Second Generation Channel Interface Processor (CIP-2) Installation and Configuration

Product Numbers: CX-CIP2-ECA1(=), CX-CIP2-ECA2(=), CX-CIP2-ECAP1(=), CX-CIP2-PCA1(=), CX-CIP2-PCA2(=), CX-CIP2-U-ECA1(=), CX-CIP2-U-ECA2(=), CX-CIP2-U-ECAP1(=), CX-CIP2-U-PCA1(=), CX-CIP2-U-PCA2(=), CAB-PCA-Y=, CAB-PCA-VA=, CAB-PCA-VB= <Caveat ID>

This document contains instructions for installing (or replacing) the second-generation Channel Interface Processor (CIP2) in the Cisco 7000 series routers and the Cisco 7500 series routers.

Note The following Cisco IOS releases support the CIP2: Release 10.2(13) or later, Release 10.3(13) or later, Release 11.0(10) or later, or Release 11.1(5) or later. For earlier releases, CIP2 is supported with a special microcode image.

This microcode image is available through download from Cisco Connection Online (CCO), on disks shipped with the CIP2 when shipped separately from a system (as a spare), or is already in Flash memory on a preconfigured system. (For instructions on placing CIP2 microcode in Flash memory, see the "CIP2 Microcode Guidelines" section.)

We recommend that you load and use the version of CIP2 microcode that is bundled with your Cisco IOS software. If you choose not to, you must then copy a CIP2 microcode image into Flash memory and use a specified configuration command to instruct the Cisco IOS software to use this microcode image instead of the microcode image bundled with your version of the Cisco IOS software; however, this is unnecessary if you load the bundled, recommended CIP2 microcode version.

(For general information on CIP2 microcode, refer to the "CIP2 Microcode Overview" section. For specific instructions on configuring the Cisco IOS software to use a CIP2 microcode image from Flash memory, refer to the "CIP2 Microcode Upgrade Overview" section.)

Note For additional specific CIP2 software and hardware requirements, refer to the "CIP2 Software, Hardware, and Microcode Prerequisites" section.

Your CIP2 might contain a newer hardware version of the ESCON channel adapter (ECA). For additional specific software, hardware, and microcode requirements for the next-generation ECAs, refer to the "ECA Software, Hardware, and Microcode Prerequisites" section. For information on how to determine if your CIP2 contains a newer version of the ECA, refer to the "Verifying the ECA Hardware Version by Examining the ECA Hardware" section or the "Verifying the ECA Hardware Version Using the show controllers cbus Command" section.

For complete and detailed descriptions of CIP2-related interface and configuration commands, configuration options, and requirements, refer to the appropriate configuration and command reference publications listed in the "Related Documentation" section.

The show version and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running. The show microcode command lists the bundled microcode (target hardware) version for each processor type. The CIP (and now CIP2) microcode is no longer bundled in Cisco IOS 11.1 and later, so the show microcode command lists the default microcode that should be used with this Cisco IOS version. The show controller cbus command shows the microcode version you are running. (For additional descriptions of configuration commands, refer to the publications listed in the "Related Documentation" section.)

You can determine the current version of software or microcode stored in Flash memory either by removing the processor module and checking the Flash device label or by using the show controller cbus command and checking the EPROM version number in the output. (Refer to the "CIP2 Microcode Guidelines" section, for basic configuration information, and to the appropriate software documentation for complete configuration instructions and examples, listed in the "Related Documentation" section.)

If the displays indicate that the required system software and microcode is not available in your system, refer to the "Cisco.com" section, or contact a service representative for upgrade information.

CIP2 Microcode Overview

Microcode, also known as firmware, is a set of processor-specific software instructions that enables and manages the features and functions of a specific processor type. At system startup or reload, the system loads the microcode for each processor type present in the system.

The CIP2 microcode boot image resides in a Flash memory device on the CIP2 motherboard. The entire CIP2 microcode image is delivered on a Flash memory card, on floppy disks, or is available via download from CCO.

New microcode is released to enable new features, improve performance, or fix bugs in earlier versions. The Cisco 7000 series and Cisco 7500 series routers feature downloadable software and microcode for most upgrades. These features enable you to download new (upgraded) images remotely, store the images in router memory, and load the new images at system startup without having to physically access the router. You can store multiple versions for a specific processor type in Flash memory, and use configuration commands to specify which version the system should load at startup. All interfaces of the same type (for example, all CIP2s) use the same microcode image.

Caution To ensure proper operation of the CIP2, and to preclude system problems, you should use only the CIP2 microcode image that is recommended for the version of Cisco IOS you are running (see Table 2).

By default, the CIP2 microcode is loaded from either onboard Flash memory (if you have a Cisco 7000 or Cisco 7010 with an RP) or the Flash memory card in slot0 for the Cisco 7500 series routers. The default CIP2 microcode version can be found by entering the show microcode command.

The following is a partial-display example of the show microcode command output:

(additional display text omitted from this example)


Microcode flash default images

Note For all Cisco IOS releases earlier than Cisco IOS Release 11.1, the filenames of all CIP2 microcode images use the following nomenclature: cippnn-nn, where nn-nn is the specific microcode version. In Cisco IOS Release 11.1 or later, the filenames of all CIP2 (and CIP) microcode images use the nomenclature cipnn-nn.

ECA Software, Hardware, and Microcode Prerequisites

The ECA/CIP2-motherboard assemblies ship as follows:

•Combination PCA and ECA—CX-CIP2-ECAP1(=)

•One ECA on a dual carrier—CX-CIP2-ECA1(=)

•Two ECAs on a dual carrier—CX-CIP2-ECA2(=)

(Add an equal sign (=) to the product number when you order interface processors as spares.)

One of three hardware versions of the ECA will be installed on your CIP2. The three hardware versions of the ECA can be used in all Cisco 7000 series and Cisco 7500 series routers. The three versions of the ECA are also compatible with each other and with the CIP2.

However, the second and third ECA hardware versions have specific restrictions regarding the Cisco IOS software release your host Cisco 7000 series or Cisco 7500 series router is running, and the CIP2 microcode images to use that are compatible with the second and third ECA hardware versions and the Cisco IOS software images they require.

For information on determining the ECA hardware version on your CIP2, refer to the "Verifying the ECA Hardware Version by Examining the ECA Hardware" section or the "Verifying the ECA Hardware Version Using the show controllers cbus Command" section.

The following are the specific Cisco IOS software and CIP2 microcode requirements that we recommend you carefully observe before you use the second or third ECA hardware versions installed on your CIP2 card:

•CIP2 Microcode Release cipp21-14 or later, for Cisco 7000 series and Cisco 7500 series routers running Cisco IOS Release 11.0(14) or later

•CIP2 Microcode Release cipp-k-22-15 or later, for Cisco 7000 series and Cisco 7500 series routers running Cisco IOS Release 11.0(14)BT or later

•CIP2 Microcode Release cip22-15 or later, for Cisco IOS Release 11.1(10) or later, or Release 11.2(5) or later

•All CIP2 microcode releases that work with the Cisco IOS Release 11.3 or later are compatible with the second or third ECA hardware version.

The appropriate CIP2 microcode images are bundled with the Cisco IOS software.

Verifying the ECA Hardware Version by Examining the ECA Hardware

This section contains information on how to determine which hardware version of the ECA is installed on your CIP2. Because ECAs ship under identical product numbers, you must refer to the different part numbers (73-xxxx-xx) and component layouts of the three ESCON channel adapter cards, which are shown in Figure 1, Figure 2 , and Figure 3, then make the appropriate comparisons to the CIP2/ECA assembly shipped to you.

The second and third hardware versions of the ECA are identified by part numbers 72-3936-02 or greater ( Figure 1) or 73-2185-02 or greater ( Figure 2). The first ECA hardware version is part number 73-1201-02 or lower ( Figure 3).

If you determine that you have the second or third ECA hardware version ( Figure 1 or Figure 2), you must observe and comply with the preceding ESCON channel adapter software and microcode prerequisites.

If you determine that you have the first ECA hardware version ( Figure 3), no further action is required.

Figure 2 Second ECA Hardware Version Installed on CIP2

Figure 3 First ECA Hardware Version Installed on CIP2

Verifying the ECA Hardware Version Using the show controllers cbus Command

This section provides an alternate method for verifying your ECA's hardware version.

Note If you have Cisco IOS software and CIP2 microcode images loaded and running that support the second and third ECA hardware versions (see Table 2 and the "ECA Software, Hardware, and Microcode Prerequisites" section), then you can also verify which ECA hardware version you have installed using the show controllers cbus command.

Refer to the arrow in the following partial-display example of the show controllers cbus command; a second or third ECA hardware version is indicated by hw version 02 or  hw version 03: 

Router# show controllers cbus

If the installed ECA is the second ECA hardware version, then  hw version 02 is displayed, as follows: 

(additional text omitted from this example)

 
—>  ECA0: hw version 02, microcode version C50602D4

If the installed ECA is the third ECA hardware version, then  hw version 03 is displayed, as follows: 

(additional text omitted from this example)

 
—>  ECA0: hw version 03, microcode version C50602D4

Note If you determine that you have the second or third hardware version of the ECA (hw version 02 or hw version 03 is displayed), you must observe and comply with the ECA software and microcode prerequisites (refer to Table 2 and the "ECA Software, Hardware, and Microcode Prerequisites" section).

If you determine that you have the first hardware version of the ECA (hw version 00 or hw version 01 is displayed), no further action is required.

If you see either of the following sets of error messages displayed, you must upgrade the Cisco IOS software and CIP2 microcode by observing and complying with the ECA Cisco IOS software and microcode prerequisites (refer to Table 2 and the "ECA Software, Hardware, and Microcode Prerequisites" section). 

%CIP2-0-MSG: %ADAPTER-0-DIAGFAIL: Port 0 failed the I/O chip tests diagnostic 
%CIP2-0-MSG: %ADAPTER-0-DIAGDATA: Module Call: 123 Error ID: FF85


%CIP2-0-MSG: %ADAPTER-0-DIAGFAIL: Port 0 failed the Electrical wrap diagnostic

%CIP2-0-MSG: %ADAPTER-0-DIAGDATA: Module Call: 1221 Error ID: FE14

Note Running CIP2 microcode versions earlier than cip21-11 and cip22-12 with the second or third ECA hardware versions will always result in error messages. Running CIP2 microcode versions earlier than cip21-14 and cip22-15 with the second or third ECA hardware versions might result in error messages.

GEM DISSE ANVISNINGER


Electrical Equipment

Follow these basic guidelines when working with any electrical equipment:

•Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

•Disconnect all power and external cables before moving a chassis.

•Do not work alone when potentially hazardous conditions exist.

•Never assume that power has been disconnected from a circuit; always check.

•Do not perform any action that creates a potential hazard to people or makes equipment unsafe.

•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Telephone Wiring

Use the following 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.

Preventing Electrostatic Discharge Damage

Electrostatic Discharge Damage (ESD), which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures.

Following are guidelines for preventing ESD damage:

•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

•When you work at the interface processor end of the chassis, connect the equipment end of the strap to a captive installation screw on an installed interface processor, or to any unpainted chassis surface.

•When you install a processor module, use the ejector levers to properly seat the bus connectors in the backplane, then tighten both captive installation screws.

•Handle processor modules by the carrier handles and carrier edges only; never touch the board or any connector pins.

•When you remove a processor module, place it card side up on an antistatic surface or in a static shielding bag. Immediately place the module in a static shielding bag if you need to return it to Cisco.

•Avoid contact between electronic equipment and clothing. Antistatic straps only protect the equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Guidelines for Interface Processor Removal and Installation

This section describes mechanical functions of system components, emphasizes the importance of following correct procedures to avoid unnecessary board failures, and is for background only; specific procedures follow in the "CIP2 Hardware Installation" section.

You can remove and replace interface processors while the system is operating; you do not need to notify the software or reset the system power. This functionality enables you to add, remove, or replace interface processors with the system online, which provides a method that is seamless to end users on the network, maintains all routing information, and ensures session preservation.

After an interface processor is reinstalled, the system brings on line only interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command.

Caution The system can indicate a hardware failure if you do not follow proper procedures. Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or inserting another interface processor. Disrupting the sequence before the system completes its verification can cause the system to interpret hardware failures.

All interface processors have ejector levers that allow you to firmly seat an interface processor in the interface processor slot. The function of the ejector levers is to align and seat the card connectors in the backplane.

Caution Always use the ejector levers to remove or install the CIP2. The ejectors help ensure that backplane connectors on the card are fully seated in, or fully ejected from, the backplane. Failure to use the ejector levers could result in a partial backplane connection, which can hang the system.

The captive installation screws on the ends of the CIP2 faceplate, when tightened, provide EMI shielding and also help ensure proper seating in the backplane. After using the ejector levers to install a CIP2, tighten the captive installation screws to prevent the CIP2 from becoming partially dislodged from the backplane. These screws must be tightened to meet EMI specifications.

Tools and Parts Required

You need the following tools and parts to install or replace a CIP2. If you need additional equipment, contact a customer service representative for ordering information.

•Number 2 Phillips or one-quarter-inch flat-blade screwdriver for the captive installation screws on the CIP2. (Although most interface processors use slotted screws, some interface processor carriers use Phillips screws.)

•A new CIP2 shipped as one of the product numbers listed in the "CIP2 Model Numbers" section.

•The appropriate cables for your CIP2 type: bus and tag for a PCA (with terminal blocks or 78-pin connectors) and/or ESCON fiber with duplex connectors for an ECA.

•ESD-preventive wrist strap or other device for preventing ESD damage.

•Interface processor filler (MAS7K-BLANK) if you are removing a CIP2 and not installing a new CIP2 or other interface processor in the empty slot.

Channel Attachment Overview

A mainframe channel (referred to as a channel) is an intelligent processor that manages the protocol on the communications media and controls the data transfer to and from the main central processing unit (CPU) storage. Devices called input/output processors (IOPs) communicate between the host CPU and the channel. One IOP controls multiple channels, and there is no relationship between the number of CPUs and the number of IOPs.

The channel relieves the mainframe CPU of direct communication with input/output (I/O) devices, which saves processing cycles and allows data processing and communications tasks to run concurrently. Channels use one or more channel paths as the links between mainframes and I/O devices. I/O devices are connected directly to control units, which provide the logical capabilities required to operate and control the I/O devices.

CIP2 Overview

The CIP2 provides up to two channel interfaces for Cisco 7000 series and Cisco 7500 series routers; in some situations, this can eliminate the need for a separate front-end processor (FEP). The CIP2 contains combinations of a bus and tag (also called an original equipment manufacturer's interface [OEMI] and a parallel I/O interface) adapter and an Enterprise Systems Connection (ESCON) adapter. The bus and tag adapter is called the Parallel Channel Adapter (PCA), and the ESCON adapter is called the ESCON Channel Adapter (ECA). (For important information on the ECA hardware versions refer to the "ECA Software, Hardware, and Microcode Prerequisites" section.) The PCA and ECA connect directly to the CIP2, and all combinations of the two adapters are available.

Note The ECAs and PCAs must be upgraded or replaced (in the field) by a Cisco-certified maintenance provider only. The CIP2 supports online insertion and removal, which allows you to install or remove a CIP2 while the system is operating, without shutting down system power.

Caution To prevent system problems in Cisco 7000 series and Cisco 7500 series systems running Cisco IOS images earlier than Cisco IOS Release 11.1(5), CIP2 (second-generation) cards must not be installed in the same chassis system with CIP (first-generation) cards.

CIP2 Description

The CIP2 ( Figure 11) consists of a motherboard that is mounted on a metal carrier and one or two ECA and/or PCA interfaces. (The CIP2's front-panel label reads Channel Interface Processor 2.) The ECA and PCA interfaces attach to the motherboard by means of a multipin connector located at the rear edge of the adapter. The ECA and PCA provide the channel attachment interfaces to connect your CIP2 to your channel.

The CIP2 has two DRAM SIMMs and comes configured with 32 MB of DRAM as the minimum standard (default) memory configuration. The CIP2 also has a Flash memory device for storing the CIP2 microcode boot image.

Figure 11 CIP 2

Note The ECA and PCA adapters can be upgraded or replaced (in the field) by a Cisco-certified maintenance provider only.

Caution To prevent damage, and to prevent insertion problems caused by misalignment of the adapters and motherboard, do not attempt to remove the adapters or motherboard from the carrier.

CIP2 Model Numbers

There are three CIP2 carrier types, which offer the following five interface adapter combinations:

•One PCA on a PCA/ECA carrier—CX-CIP2-PCA1

•Combination PCA and ECA—CX-CIP2-ECAP1

•One ECA on a dual carrier—CX-CIP2-ECA1

•Two ECAs on a dual carrier—CX-CIP2-ECA2

•Two PCAs on a dual carrier—CX-CIP2-PCA2

Add an equal sign (=) to the product number when you order interface processors as spares. For example, the product number for the one PCA on a PCA/ECA carrier if ordered as a spare is CX-CIP2-PCA1(=).

The ECA has a female, duplex connector, and the PCA has a female, DB-78 connector. Figure 12 shows the ECA and PCA interface combinations that are available.

Figure 12 CIP2 Interface Channel Adapter Combinations

Caution The second and third ECA hardware versions have specific software, hardware, and microcode requirements that must be observed to ensure proper system operation. To determine if you have the first ECA or the second ECA on your CIP2, refer to the "ECA Software, Hardware, and Microcode Prerequisites" section.

CIP2 DRAM Configurations

Each CIP2 model is available in the following configurations of dynamic random-access memory (DRAM) single in-line memory modules (SIMMs):

•32-MB DRAM—MEM-CIP-32M

•32-MB DRAM—MEM-CIP-32M(=)

•64-MB DRAM—MEM-CIP-64M(=)

•128-MB DRAM—MEM-CIP-128M(=)

Note MEM-CIP-32M is the default memory configuration that ships on the CIP2. MEM-CIP-32M= is a spare memory option, which is intended for CIP2 cards ordered without DRAM.

All CIP2 DRAM upgrade products ship with the configuration note Upgrading DRAM on the CIP2 (Document Number 78-3915-xx, where xx is the latest version of the document). This configuration note is also available on the Documentation CD-ROM.

CIP2 DRAM can be upgraded in the field by Cisco-certified service personnel only.

CIP2 LED Indicators and Sequences

Following are the functions of the CIP2 LEDs ( Figure 13):

•Enabled—Indicates that the CIP2 has been enabled for operation by the system.

•Present—Indicates that the ECA or PCA adapter has been detected by the CIP2.

•Loaded—Indicates that the ECA or PCA adapter firmware has been completely loaded.

•Signal—For the ECA, this LED indicates that the Sync signal has been detected. For the PCA, this LED indicates that the Operational Out signal has been detected. Note that even though a system reset and selective reset both cause the operational out signal to drop, the signal LED will still be on during those sequences.

•Online—For the ECA, this LED indicates that an establish-logical-path request has been received from the channel. For the PCA, this LED indicates that the PCA is ready to establish connection to the host channel.

It is unlikely a system would have the resources to support the total number of available addresses.


ESCON Cable

The ECA interface uses 62.5/125 micrometer, multimode, fiber-optic cable with male duplex connectors at each end ( Figure 14). ESCON cables are not available from Cisco. Refer to the ESCON specifications in Table 3, and contact your cable supplier or the vendor of your host CPU to order the correct ESCON cable.

Figure 14 ESCON Interface Duplex Connector for the ECA

Bus and Tag Cables

Following are descriptions and illustrations of the bus and tag cables.

Y Cable

The bus and tag cable with three 78-pin connectors ( Figure 15) has a DB-78 male (PCA) connector on the CIP2 end, a DB-78 female connector on the next-control-unit end, and a DB-78 male connector on the from-host end.

Figure 15 PCA Bus and Tag Cable (Y Cable)

The bus and tag model number is CAB-PCA-Y (referred to as the Y cable). The male connector might be labeled IN and is typically black, but can also be a dark gray. The female connector might be labeled OUT and is typically light gray. The female OUT cable is nearest to the select/bypass switch, which is shown in Figure 16. (The IBM part number is 89F8392; however, this number is subject to change.)

Caution The Y cable must connect directly to the PCA. Do not connect any other cables directly to the PCA.

Note Note that the select/bypass switch is marked S (for select mode) and B (for bypass mode). The switch is located on the rear of the PCA connector ( Figure 16). The select/bypass switch is required to separate the cable from the PCA without "opening" the select-out loop.

Caution To prevent halting the system or negatively affecting the mainframe operating system, verify that the select/bypass switch is in bypass mode before you remove the PCA connector from the CIP2.

Figure 16 Select/Bypass Switch on the Rear of the PCA Connector (CAB-PCA-Y Bypass Shown

In select mode the PCA is operational, and the select-out signal is passed in a loop to all control lines on the channel. All control units have a relay that shorts the incoming select-out signal to the outgoing select-out signal when power is not applied to the control unit. When power is applied, the relay is opened, and the signal is passed to the PCA.

Without the select/bypass switch in bypass mode, the channel would need to be taken offline before servicing or replacing a CIP2. If the selected address does not match, the select-out signal is passed to the next control unit. If the select-out signal gets all the way back to the channel, the control unit being addressed is not present.

Note In bypass mode, the incoming select-out signal is shorted to the outgoing select-out signal, bypassing the PCA and allowing other devices on the channel to function properly.

Caution Make sure you provide adequate strain relief for the heavy bus and tag cables that attach to the PCA, to prevent damaging the PCA connector on the CIP2 by unintentionally disconnecting the Y cable from the PCA connector.
