Cisco ICS 7750 FRU Installation and Replacement
August 2, 2002
This document explains how to install and remove field-replaceable units (FRUs) in the Cisco Integrated Communications System (ICS) 7750 (referred to as the Cisco ICS 7750).
The following Cisco ICS 7750 components are FRUs:
•
Analog station interface (ASI) cards.
•Fan tray.
•Multiservice route processor (MRP) 200 and 300 cards.
•MRP3-8FXS and MRP3-16FXS cards.
•Power supply modules.
•System alarm processor (SAP) card.
•System processing engine (SPE) 310 cards.
•System switch processor (SSP) card.
•Voice interface cards (VICs), voice WAN interface cards (VWICs), and WAN interface cards (WICs). VICs, VWICs, and WICs are subcomponents of ASIs and MRPs.
Note This document is not intended for use with SPE200s. If you need assistance with an SPE200, contact the Cisco Technical Assistance Center (see the "Technical Assistance Center" section).
Note The MRP200 and MRP300 cards are both voice-and-data-capable routers that support digital and analog voice trunks and WAN routing interfaces to link remote Ethernet LANs to the Public Switched Telephone Network (PSTN), to existing private branch exchanges (PBXs), and to most common analog devices, such as fax machines and teleconferencing stations. The MRP300 has additional functionality provided by 16 MB of onboard Flash memory, with 64 MB of add-on Flash memory available as an option. Configuration files for the MRP200 are loaded and saved to the SPE running System Manager, whereas configuration files for the MRP300 are loaded and saved on the MRP300 in nonvolatile RAM (NVRAM).
Note The ASI81 and MRP3-8FXS cards are both voice-and-data-capable routers that can carry voice traffic over an IP network to link remote Ethernet LANs to central offices over WAN links (depending on the type of card installed in its WIC/VIC/VWIC slot). Each card can support eight connections to analog telephones, fax machines, and teleconferencing stations. The MRP3-8FXS has additional functionality provided by 16 MB of onboard Flash memory, with 64 MB of add-on Flash memory available as an option. Configuration files for the MRP3-8FXS are loaded and saved on the MRP3-8FXS in NVRAM. The MRP3-16FXS card has the same Flash memory capability, with support for 16 connections.
Note For information about removing and replacing dual in-line memory modules (DIMMs), packet voice data modules (PVDMs), and Virtual Private Networking (VPN) modules, refer to Installing Memory, PVDM, and VPN Modules in ASI Cards, MRP Cards, and SPE Cards in the Cisco ICS 7750.

You need the following tools and parts to install and maintain the system. If you need additional equipment, contact a customer service representative for ordering information.
•A number-1 Phillips screwdriver for installing the cable management bracket (recommended) and mounting the system.
•A 6-mm open-end wrench for adjusting the grounding lug.
•ESD-prevention equipment or the disposable ESD-preventive wrist strap included in the hardware accessory kit.
•Antistatic mat, foam pad, or bag for removed cards or modules. (Put removed components inside an antistatic bag if you plan to return them to the factory; if you are replacing components, place them on an antistatic mat or foam pad.)
•Cables and adapters:
–1 straight-through Category 5 Ethernet cable.
–1 RJ-45-to-DB-9 adapter.
–1 console (rolled EIA/TIA-232) cable.
To remove, install, and replace SPEs, you need the following additional tools and parts:
•Cisco ICS 7750 chassis equipped with one or more SPE310s.
•One or more spare SPE310s.
•(Optional) Application CDs for applications to be installed on the SPE(s) (for example, Cisco CallManager software for the Cisco ICS 7750).
•Windows-based PC or laptop, which may be connected both to the SSP Ethernet port and the SAP console port. (Specific requirements for this PC are described in the "PC Requirements" section.)
•Cisco ICS 7750 System Software, which can be installed from the following sources, with the following options:
–CD-ROM—The system software release 2.x.x CD-ROM contains a complete set of the system software, including Microsoft SQL Server software and Microsoft hotfixes. The CD-ROM can be used to install release 2.x on an SPE310 that does not currently have system software installed, or it can be used to upgrade an SPE310 that currently has system software release 2.1 or 2.2 installed.
For instructions on installing the software from the CD-ROM, refer to the "Upgrading System Software on SPE310s from the CD-ROM" section in Chapter 8, "Maintaining the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide. For download and installation instructions from CCO, refer to the "Downloading and Installing System Software" section in Chapter 8, "Maintaining the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide.
–CCO—Two sets of system software release 2.x.x are available for downloading from CCO:
•S77a-2.x.x.exe—This package contains the complete set of system software version 2.x.x, including Microsoft SQL Server software, and can be used for new installations or upgrades of existing system software.
•S77a-Upgrade-2.x.x.exe—This package contains only the software components changed since release 2.1 and necessary to upgrade the ICS system software from release 2.1 or 2.2. It does not contain Microsoft SQL Server software, and so, the package is smaller and results in shorter download times. This upgrade package cannot be used for SPE310 reimaging or reinstallation of ICS system software.
Two options are presented during the installation process that determine which software set will be installed:
–Install ICS System Manager Software—Select this option to install System Manager on the SPE310. There must be one (and only one) SPE310 running ICS System Manager software in the chassis.
–Install ICS Core Software—Select this option to install ICS Core Software on any additional SPEs in the chassis, if another SPE310 is already running the ICS System Manager software.

Safety Precautions and Maintenance Guidelines
This section describes guidelines that you should follow when working on the Cisco ICS 7750.
General Safety Precautions
Read the warnings in this section before working on the system.
Warning Read the installation instructions before you connect the system to its power source.
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 16A international) is used on the phase conductors (all current-carrying conductors).
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
Warning Only personnel who are trained and qualified (IP Telephony certified for the Cisco ICS 7750) should be allowed to install or replace this equipment.
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.
Warning The device is designed to work with TN power systems.
Warning The SPE contains a lithium battery. There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.
ESD Safety Precautions
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when electronic printed circuit cards are improperly handled. ESD can result in complete or intermittent failures. Always follow these ESD-prevention procedures when removing and replacing cards and other system components:
•Ensure that the chassis is electrically connected to earth ground.
•Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
•Connect the clip to an unpainted surface of the chassis frame to safely channel ESD voltages to ground.
•To properly guard against ESD damage and shocks, the wrist strap must be used correctly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms).
Caution Static voltages as low as 30 volts can cause latent damage to circuitry. Be sure to observe all standard antistatic procedures (for example, wear a grounding strap) when handling electronic equipment and components.
Warning Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place.
Safety with Electricity
Note The following guidelines are IMPORTANT SAFETY INSTRUCTIONS.
Follow these guidelines when working on equipment powered by electricity:
•Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power off.
•Disconnect all power before installing or removing a Cisco ICS 7750 chassis.
•Do not work alone if potentially hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.
If an electrical accident occurs, proceed as follows:
•Use caution; do not become a victim yourself.
•Turn off power to the chassis.
•If possible, send another person to get medical aid. Otherwise, determine the condition of the victim, and then call for help.
•Determine whether the victim needs rescue breathing or external cardiac compressions; then take appropriate action.
Note SAVE THESE INSTRUCTIONS.

Telephone Wiring Guidelines
Follow these guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Lifting and Reaching Safety Precautions
Follow these guidelines when lifting or moving the chassis:
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Lift the unit only by using handles that are an integral part of the chassis, or by grasping the chassis underneath its lower edge.
Warning Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your legs, not your back.
System Component Identification
Figure 1 shows the major components in a typical Cisco ICS 7750:
•Slots 1 through 6 can contain a combination of SPEs, ASIs, and MRPs.
•Slot 7 must contain only an SSP.
•Slot 8 must contain only an SAP.
•The Power Supply 1 and Power Supply 2 slots can each contain a power supply module (only one power supply module is required to operate the system).
•The system contains one fan tray, at the bottom of the chassis.
Note By factory-installed default, the Cisco ICS 7750 chassis comes with the SPE running System Manager installed in slot 6, and with SPEs populated from right to left. Other system cards (such as MRPs and ASIs) are populated from left to right in the chassis.
Figure 1 Cisco ICS 7750
Removing and Replacing Cisco ICS 7750 Components
This section provides general information about removing and replacing the Cisco ICS 7750 components. This section contains the following subsections:
•Best Practices for Hot Swapping
•Best Practices for Card Replacement
For detailed instructions for removing and replacing system components, see the following sections:
•Removing and Replacing SPE310s
•Removing and Replacing ASIs, MRPs, the SSP, or the SAP
•Removing and Replacing Power Supply Modules
•Removing and Replacing the Fan Tray
Warning When performing the procedures in this section, wear grounding wrist straps to avoid ESD damage to the Cisco ICS 7750. Do not directly touch the backplane with your hand or any metal tool to prevent personal injury or equipment damage.
Warning Removing cards, fans, and power supply modules can expose you to high-energy (high-amperage) circuits and possible ejection of molten metal or to the shock hazard of telephony circuit voltages. Be sure to remove all rings, watches, and other jewelry from fingers, wrists, and arms before removing panels and devices.
Note If the chassis has any empty slots, they are covered with blank panels when the Cisco ICS 7750 is shipped to you. Do not remove the panel covering an empty slot until you are ready to install a card in the slot.
Note You do not have to disassemble any system component or remove the chassis from the rack to perform any of the procedures described in this section.
Best Practices for Hot Swapping
You can hot swap cards while the Cisco ICS 7750 is operating. With hot swapping, you do not need to power down the system. However, be sure to read and follow the best practices in this section and in the "Best Practices for Card Replacement" section, and the specific instructions for removing and replacing each type of card or module before you hot swap it.
Warning Only trained and qualified (IP Telephony certified for the Cisco ICS 7750) personnel should be allowed to install or replace this equipment.
Caution When replacing a hot-swappable system card, you do not need to power down the entire chassis by using the chassis power supply switch or by unplugging the power supply. Powering down the entire chassis may cause the Cisco ICS 7750 to lose important configuration data and will interrupt any applications or functions running on other cards in the chassis. (The one exception to this is an electrical accident, in which case turning off the power is recommended; see the
"Safety with Electricity" section.)
Caution You can install only one SAP and one SSP in a single Cisco ICS 7750 chassis. If you must hot swap the SAP, the cooling fans do not operate; the system's ability to detect alarms associated with the operating environment, fans, and power supply modules is degraded; and applications using the COM ports on the SAP lose their access to those ports, until an operational SAP is properly reinserted in the chassis. If you must hot swap the SSP, the system loses LAN connectivity, and calls being made from or to Cisco IP phones that are switched through that SSP are disconnected until an operational SSP is properly reinserted in the chassis.
Note Depending on your system configuration, hot swapping of SPEs, ASIs, or MRPs can adversely affect users connected to the system. For example, if Cisco CallManager is running on only one SPE, hot swapping that SPE disconnects calls to or from the Public Switched Telephone Network (PSTN) and prevents the system from processing further PSTN traffic until an operational SPE is properly reinserted into the chassis. Similarly, hot swapping an ASI or MRP that is in the process of routing voice or WAN traffic prevents that traffic from reaching its destination. Contact your Cisco sales representative for guidelines on installing cards and software on your system for maximum availability and redundancy.
Best Practices for Card Replacement
This section provides best practices for replacing system cards:
•Best Practices for Resetting or Removing Cards
•Best Practices for Inspecting the Chassis Backplane and Card Connectors Before Installing Cards
•Best Practices for Installing Cards
Best Practices for Resetting or Removing Cards
Consult these guidelines (and the instructions in "Best Practices for Hot Swapping") before resetting or removing cards:
•Check card LEDs before attempting to reset or remove a card.
•Do not press the SHTDN button on any card in the Cisco ICS 7750 chassis unless you are directed to do so.
Caution Always use the extractor levers to disengage cards from the chassis. Failure to use the levers can cause system error messages that indicate a card failure. However, do not use the extractor levers to lift or support the weight of the cards.
Best Practices for Inspecting the Chassis Backplane and Card Connectors Before Installing Cards
Before you install a card, perform the following inspections:
•Inspect the backplane for bent pins (see Figure 2) or bent dividers between rows.
If the backplane has bent pins, do not install a card in that slot. Installing a card into a damaged backplane slot will damage the connector on the card.
Figure 2 Backplane Inspection
•Inspect the card for damaged holes on the connector (see Figure 3).
If the connector has damaged holes, do not install the card. Installing a card that has a damaged connector will damage the backplane. Return damaged cards to Cisco (see the "RMA Return Instructions" section).
Figure 3 Card Connector Inspection
Best Practices for Installing Cards
When installing cards, consult these guidelines, and follow the card-specific instructions:
•Do not force the card faceplate into its slot. This action can damage the pins on the backplane if they are not aligned properly with the module or card.
•Before installing a card, be sure to align its top and bottom edges with the upper and lower card guides in the chassis slot. Do not attempt to push the card into its slot until its top and bottom edges are in proper alignment.
•When installing a card, carefully slide it all the way into the slot, and press both extractor levers inward (toward the center of the card) as far as they will go. The front of the card should now be flush with the other cards in the chassis. Using this method ensures that the card connector correctly mates with the backplane. For more information and an illustration on installing a card, see the "Installing an SPE" section.
If the card is particularly tight in its slot, or if the extractor lever engagement hooks are not engaging with the chassis, you might need to take the card out and insert it again to cause its extractor levers to engage properly.
Caution Do not push the card with so much force that it bends in the middle, since bending a card might force its sensitive electronic components to come in contact with adjacent cards.
•The card or module should be firmly seated in the slot. Any card or module that is only partially connected to the backplane can disrupt system operation.
•After card installation is complete, always use the lock-down screws (at the top and bottom of the card) to secure the card firmly in place in the chassis. If the screws do not engage, the extractor levers are not properly aligned, and the card is not firmly seated in the chassis. Remove and reinsert the card until you can fully tighten the screws.
Removing and Replacing SPE310s
This section describes how to determine the function of an SPE, tells how to install and replace SPEs, and contains the following subsections:
•Accessing the SPE310
•Removing an SPE
•Installing an SPE
•Verifying SPE Installation
•Configuring a New or Replacement SPE
•Downgrading ICS System Software
Note This document is not intended for use with SPE200s. If you need assistance with an SPE200, contact the Cisco Technical Assistance Center (see the "Technical Assistance Center" section).
Accessing the SPE310
You can access the SPE310 Windows interface to determine whether the SPE is running ICS System Software or ICS Core Software. The SPE310 Windows interface can be accessed in either of the following ways:
•Accessing the SPE310 Windows Interface Through Terminal Services Client
•Accessing the SPE310 Windows Interface Through Directly Connected Peripherals
Refer to Chapter 5, "Operating the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide for more information on accessing the SPE310 Windows interface through Terminal Services Client or through directly connected peripherals.
Accessing the SPE310 Windows Interface Through Terminal Services Client
To access the SPE310 Windows interface through Terminal Services Client, follow these steps:
Step 1 On the PC that you use to administer the Cisco ICS 7750, choose Start > Programs > Terminal Services Client > Client Connection Manager.
Step 2 Use the Client Connection Manager to open a Terminal Services connection with the target SPE:
•If you already have a Terminal Services Client connection defined for the target SPE, choose it, and choose File > Connect.
•If you do not have a Terminal Services Client connection defined for the target SPE, choose File > New Connection, and follow the instructions in the wizard, and then choose File > Connect.
The Terminal Services Client window opens. You can use Terminal Services Client to access standard Windows utilities on the SPE310, such as Windows Explorer and the Control Panel.
Note You cannot perform a full installation of ICS System Manager (including Microsoft SQL server software) over Terminal Services Client. You must access the SPE310 through directly connected peripherals to install ICS System Manager. You can install ICS Core Software over Terminal Services Client.
Accessing the SPE310 Windows Interface Through Directly Connected Peripherals
You can connect a monitor, keyboard, and mouse directly to the SPE310 to access the Windows user interface, as follows:
Step 1 Connect the monitor cable to the video port on the SPE310, and power on the monitor.
Step 2 Do one of the following, based on the type of peripherals that you are using:
•USB—Connect a USB keyboard to one SPE310 USB port, and connect a USB mouse to the other SPE310 USB port.
•PS/2—Connect the "Y" splitter cable for your keyboard and mouse to the keyboard/mouse port on the target SPE310. Then connect your keyboard and mouse to the available ends of the "Y" splitter cable.
Note If you are using the "Y" splitter cable to connect a PS/2 mouse and a keyboard to the SPE310, the keyboard and mouse must be connected at or before the time that the SPE310 is rebooted in order to be recognized by the operating system. A USB keyboard and mouse are usually recognized without rebooting the operating system.
Note For a summary of the issues related to the connection of peripherals to SPE310s, as well as best practices for using peripherals with SPE310s, refer to the "Using Peripherals with SPE310s" section in Chapter 5, "Operating the Cisco ICS 7750," in the Cisco ICS 7750 Installation and Configuration Guide.
Installing Microsoft Terminal Services Client
If Microsoft Terminal Services Client is not installed on your PC, complete the following steps:
Step 1 Open Netscape Communicator or Microsoft Internet Explorer.
Step 2 In the Location or Address field, enter the following URL:
http://www.microsoft.com/windows2000/downloads/recommended/TSAC/tsmsi.asp
Step 3 Follow the instructions to download and install Microsoft Terminal Services Client.
Determining the Function of an SPE
Follow these steps to use ICS System Manager to determine whether the SPE installed in the chassis is running ICS Core Software or ICS System Manager software:
Step 1 On a PC connected to the ICS 7750 or on the SPE running System Manager, launch a web browser, and access ICS System Manager by entering the following in the address field:
http://SPE IP address/ics
where SPE IP address is the IP address of the SPE running System Manager.
The ICS System Manager screen appears in the browser window, and you are prompted for a user ID and password.
Step 2 In the User ID field, enter admin.
Step 3 In the Password field, enter the ICS super admin password (set during ICSConfig).
Step 4 Click Login.
Step 5 Examine the displays provided in ICS System Manager to determine the function of each card in the chassis. For example:
ICS System Manager: V3.2.8
or
ICS Core Software: V3.2.8
Step 6 Exit ICS System Manager when you have finished.
Removing an SPE
This section explains how to remove SPEs. Figure 4 shows how to remove a card.
Figure 4 Removing Cards from the Cisco ICS 7750 Chassis
You do not have to turn off the power for these procedures.
Caution When replacing an SPE, do not power down the entire chassis by using the chassis power supply switch or by unplugging the power supply. Powering down the entire chassis may cause the Cisco ICS 7750 to lose important configuration data and will interrupt any applications or functions running on other cards in the chassis.
Note Powering down an SPE will interrupt any services or applications running on that SPE. Measures should be taken to minimize impact on users.
Note If you have a chassis with more than one SPE installed and if you are not certain which SPE is running System Manager and which card or cards are running other applications, you can use ICS System Manager to check. See the "Determining the Function of an SPE" section.
Complete the following steps to remove an SPE:
Step 1 Press the SHTDN button on the card that you want to remove.
Note If the SPE to be removed is already shut down, this step is unnecessary, and you can proceed to Step 2.
The STATUS LED on the card starts blinking; after several minutes, it turns off. Wait for the STATUS LED to turn off before continuing.
Step 2 Put on an ESD-preventive wrist strap, and attach it to an unpainted chassis surface.
Caution To prevent ESD damage, handle cards by the edges only, and use an ESD-preventive wrist strap or other grounding device.
Step 3 For the SPE that you wish to remove, completely loosen the lock-down screws (at the top and bottom of the card).
Step 4 Press the upper and lower extractor levers outward (away from the center of the card) at the same time to disengage the card from the backplane. Pull the card out only far enough (about 1 inch) to disengage from the backplane; do not completely remove the card from the chassis.
Caution Always use the extractor levers to disengage or seat cards. Failure to use the levers can cause system error messages that indicate a card failure. Do not use the extractor levers to lift or support the weight of the cards.
Note Unseating or removal of the SPE should be done only when the SPE has been safely shut down. In normal use, you should not unseat or remove an SPE without first ensuring that the SPE has been shut down.
Warning High performance devices on system cards can get hot during operation. To remove a card, hold it by the faceplate and bottom edge. Allow the card to cool before touching any other part of it or placing it an anti-static bag.
Step 5 Grasp the extractor levers, and gently pull the card partially out of the chassis slot until you can grasp the card front panel with one hand. Place your other hand under the card to balance the weight of the card as you prepare to pull it out of the slot.
Step 6 Pull the card straight out of the slot. Avoid touching the circuitry or any connector pins.
Step 7 Place the card on an antistatic mat or foam pad until you are ready to reinstall it in the chassis. If you plan to return the card to the factory, place it inside an antistatic bag, and see the "RMA Return Instructions" section.
Step 8 Repeat Step 1 through Step 7 as needed to remove additional SPEs.
Installing an SPE
This section explains how to install SPEs. Figure 5 shows how to install a card.
Figure 5 Installing Cards in the Cisco ICS 7750 Chassis
You do not need to power down the entire chassis for these procedures.
Caution When installing cards, be sure to apply equal amounts of pressure to the top and bottom of the card. You can damage the card and the chassis backplane if you apply too much pressure to either the top or the bottom of the card.
Follow these steps to install an SPE:
Step 1 Put on an ESD-preventive wrist strap, and attach it to an unpainted chassis surface.
Caution To prevent ESD damage, handle cards by the edges only, and use an ESD-preventive wrist strap or other grounding device.
Step 2 Align the SPE with the upper and lower card guides in an available chassis slot, and make sure that the extractor levers are in the open position (pointing up and down).
Step 3 With the top and bottom edges of the card in the card guides, gently slide the card into the chassis until you feel resistance. Because there are grounding clips near the front and rear of the card guides, you might need to increase the amount of force that you use to get the card past the grounding clips. If you encounter extreme resistance, pull the card out slightly and push it back in again.
Step 4 Press the upper and lower extractor levers inward (toward the center of the card) at the same time until they lock into their slots. This step firmly seats the SPE into the chassis.
Step 5 Fasten the lock-down screws for the SPE, securing it in the chassis.
Step 6 Verify the installation (see the "Verifying SPE Installation" section).
Verifying SPE Installation
This section explains how to verify an SPE installation.
To verify that the SPE is operating correctly, check that its STATUS LED is functioning as follows:
•The STATUS LED blinks green when the power-on self-test (POST) is in process or the card is shutting down.
•The STATUS LED is green when the POST is complete, card initialization is complete, and the card is operating correctly.
•The STATUS LED is off when the shutdown process is complete (indicates that the card can be removed from the chassis or that power is off for the entire Cisco ICS 7750).
Note The ALARM LED on Cisco ICS 7750 cards turns yellow during the POST. If the ALARM LED on any card does not turn off upon completion of the POST, that card is not functioning correctly. For general information on solving problems with cards, refer to Chapter 3, "Solving Hardware Problems," in the Cisco ICS 7750 Troubleshooting Guide.
Configuring a New or Replacement SPE
This section provides the procedures for configuring a new or replacement SPE after the SPE is installed. This section contains the following subsections:
•SPE Installation and Replacement Scenarios
•Installing a New SPE for Applications
•Replacing an Existing SPE for Applications
•Replacing the SPE Running System Manager
SPE Installation and Replacement Scenarios
This section describes the scenarios in which SPE installation and/or replacement might be required:
•Installing a new SPE for applications—In this instance, you already have a functioning SPE running System Manager in the Cisco ICS 7750 chassis, and you might have one or more existing SPEs for applications. The goal, as identified in this scenario, is to add another SPE and set it up so that it can have applications installed on it. (See the "Installing a New SPE for Applications" section.)
•Replacing an existing SPE for applications—In this case, you have an SPE for applications already installed in the chassis, but you wish to replace this SPE with a new one. Here, you might also want to migrate saved configuration data and settings to the new SPE once it is in place and operational. (This scenario includes the assumption that a successful backup was completed for the previously installed applications.) In this scenario, the existing SPE running System Manager and any other installed SPEs are left intact and unchanged. (See the "Replacing an Existing SPE for Applications" section.)
•Replacing the SPE running System Manager—This is a more complex scenario, and it requires the greatest number of steps to complete. In addition, although adding or replacing an SPE for applications can be done while the chassis is running, with minimal impact on users and services, replacing the SPE running System Manager takes more time and might require temporary interruption of services. For this reason, replacing the SPE running System Manager is best done at a time when interruption of service will have minimal impact, such as during scheduled maintenance. (See the "Replacing the SPE Running System Manager" section.)
Note Because there can be only one SPE running System Manager in a chassis, system software and any application data must be backed up (if possible) before removing the original SPE running System Manager.
The following sections will address each of these scenarios. You need to follow only the instructions in the scenario that applies to your situation.
Note The procedures and steps for installing specific applications (such as Cisco CallManager) are beyond the scope of this document. For information on how to install, configure, back up, and restore Cisco ICS 7750-compatible applications, refer to the user documentation for those applications. If you still need assistance, see the "Obtaining Technical Assistance" section.
Note To reduce chances for error and other conditions which could result in lengthy interruption of Cisco ICS 7750 services, it is recommended that you attempt to install or replace only one SPE in a chassis at a time. If you need to perform this operation for more than one SPE in a chassis, complete the entire installation or replacement process for a single SPE, and verify that is functioning properly, before installing or replacing the next SPE. In such a situation, always replace the SPE running System Manager first (if it is one of the SPEs that need to be replaced).
Installing a New SPE for Applications
The procedures in this section apply to installing a new additional SPE in a Cisco ICS 7750 chassis. This assumes that the new additional SPE was shipped from Manufacturing, and as such, has the applicable ICS software installed. These procedures do not apply to replacing an existing SPE for applications or to replacing the SPE running System Manager.
Note To replace an existing SPE for applications, see the "Replacing an Existing SPE for Applications" section. To replace the SPE running System Manager, see the "Replacing the SPE Running System Manager" section.
To install the new SPE for use as an additional SPE that runs applications, insert the SPE into an empty slot in the Cisco ICS 7750 chassis, following the instructions detailed in the "Installing an SPE" section.
Note After you install the SPE in the chassis, wait several minutes before you begin configuring the new SPE, so that the Windows 2000 operating system can finish booting. If you start ICSConfig before Windows 2000 is running, the new SPE will not be discovered, resulting in an error condition.
After you have installed the new SPE into the chassis, you can proceed to the "Using ICSConfig to Configure the New SPE for Applications" section.
If you wish to install applications on the SPE, see the "Installing Applications" section.
Using ICSConfig to Configure the New SPE for Applications
To configure the new SPE for applications, follow these steps:
Step 1 On a PC with network connectivity to the Cisco ICS 7750 or on the SPE running System Manager, launch a web browser.
Step 2 Enter the following URL:
http://SPE IP address/icsconfig/
where SPE IP address is the IP address of the SPE running System Manager.
Step 3 Log in as administrator, using the user ID administrator and the current password (the default is changeme).
Step 4 Click ICS 7700 System Setup.
Step 5 Make any necessary changes to the configuration screens. (Refer to the Cisco ICS 7750 Installation and Configuration Guide for instructions.) Make a note of the IP address of the new SPE. Go to Step 6 to see the changes.
Step 6 When you have configured the necessary settings, the Summary page displays a list of all the configuration pages and the data entered in each field.
All of the page names listed on the Summary page are links to the configuration pages, where you can change any information that you entered. To change any of the settings, click the associated hyperlinked page. When the settings are correct, click Next to continue to the Ready to Submit page.
Note The Ready to Submit page provides instructions on what to do after you submit the changes to the Cisco ICS 7750. Submitting and processing these changes can require up to 20 minutes.
Step 7 Click Submit.
Caution After clicking
Submit, do not reboot your Cisco ICS 7750 or perform any configuration tasks on the Cisco ICS 7750 until this process has completed.
Step 8 Verify that the SPE is functioning correctly (see the "Verifying Card Installation" section).
After you have installed and configured the SPE, you can continue with the "Installing Applications" section.
Installing Applications
For information on how to install and configure applications on the newly installed SPE, refer to the documentation for the applications.
Caution If you are upgrading system software on an SPE running Cisco Unity, you may need to manually stop some of the services that are running on the Cisco Unity SPE before you can perform the upgrade. Refer to the Release Notes for System Software Release 2.4.0 on the Cisco ICS 7750 for detailed steps to follow to complete the Cisco Unity upgrade.
Replacing an Existing SPE for Applications
The procedures described in this section apply to replacing (or swapping) an existing SPE that is running applications only (not the SPE running System Manager). In this scenario, you remove an SPE for applications and replace it with a new SPE intended to perform the same functions as the previous SPE.
Note To install an additional SPE for applications, see the "Installing a New SPE for Applications" section. To replace the SPE running System Manager, see the "Replacing the SPE Running System Manager" section.
To replace an SPE for running applications that is already installed in an ICS 7750 chassis, you need to complete the following in order:
1. Back up configuration data and settings for the original SPE for applications (if application backup functions are available). See the "Backing Up Application Software Data" section.
2. Shut down and remove the SPE that is to be replaced. See the "Shutting Down and Removing the SPE for Applications" section.
3. Insert and power up the new SPE in the same or a different chassis slot. See the "Installing the Replacement SPE for Applications" section.
4. Set the correct date, time, and host name for the SPE. See the "Setting the Date, Time, and Host Name on the Replacement SPE" section.
5. Use ICSConfig to configure the SPE. See the "Using ICSConfig to Configure the Replacement SPE for Applications" section.
6. Install applications and restore application configuration data and settings (if available). See the "Installing Applications" section.
The following sections describe the process in detail.
Backing Up Application Software Data
For information on how to back up application data on an existing SPE, refer to the documentation for each application. Note that not all applications have built-in backup and restore features; in those cases, you need to back up and restore the application data manually.
If you do plan to restore backed up application data, you should also record the IP address and host name of the SPE being replaced. Later, during the configuration phase of setting up the SPE for applications, you will be directed to rename the SPE to match the host name of the card you removed.
To locate the SPE host name, follow these steps:
Step 1 Connect a monitor cable to the video port on
