This document discusses the Route Switch Processor (RSP4/4+), an optional system processor available for the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers. The RSP4+ significantly increases the performance for most protocols and services over the RSP2 and the RSP4.

The RSP4/4+ supports the high system availability (HSA) feature, which allows two RSP4/4+s (or an RSP2 and an RSP4/4+) to be used in a Cisco 7507, Cisco 7505-MX, Cisco 7513, or Cisco 7513-MX router. The redundancy increases system availability during planned and unplanned network outages. See the "Configuring High System Availability" section for more information on HSA.

The RSP4/4+ also supports high availability (HA), a series of features that operates similarly to HSA, but which further minimizes system downtime. (HSA is the system default.) For more information on HA, see the "Enabling High Availability Features" section.

With HA or HSA enabled, the RSP4/4+ supports online insertion and removal (OIR).

Product Description

This section discusses the following topics:

The RSP4/4+ supports the VIP2, the VIP4 in the Cisco 7000 series routers, and the VIP2, VIP4, and the VIP6-80 in the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers. (See Figure 2 and Figure 1.) The RSP4 is not available as an upgrade to the RSP1 or RSP2.The RSP4+ is not available as an upgrade to the RSP1, RSP2, or RSP4.

Storing the IOS software images in Flash memory enables you to download and boot from upgraded Cisco IOS software images remotely or from software images resident in the RSP4/4+ Flash memory, without having to remove and replace read-only memory (ROM) devices.

Note   For specific Cisco IOS software release compatibility, refer to the "System Software" section, and to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl .

The RSP4/4+ also contains:

In addition to running the system software from Dynamic Random-Access Memory (DRAM), the RSP4/4+ contains and executes the following management functions that control the system:

The high-speed switching section of the RSP4/4+ communicates with and controls the interface processors on the high-speed CyBus. This switching section of the RSP4/4+ decides the destination of a packet and switches it based on that decision.

Note   When configuring the router for HSA or HA, you can use the RSP4 and RSP4+ in the same router, but the RSP4+ should be configured as the active RSP.

The RSP4/4+ installs in the following slots on your Cisco 7000 or Cisco 7500 series router:

The RSP4+ is an enhanced version of the RSP4 with larger default program memory (64 MB versus 32 MB), Error Correction Code (ECC) memory protection, and compatibility with Cisco IOS software releases that support the current RSP4.

Note   The Active/Standby switch has been deactivated in software. The reset button boots the system.

Note   A bank of hardware (Media Access Control [MAC]-layer) addresses for the interface ports is contained in a Non-Volatile Random-Access Memory (NVRAM) device on the router backplane.

CPU

The CPU used in the RSP4/4+ is an IDT R5000 Reduced Instruction Set Computing (RISC) processor, which runs at an external bus clock speed of 100 MHz and an internal clock speed of 200 MHz.

Memory Components

Table 1 shows the memory components on the RSP4/4+.

DRAM

DRAM stores routing tables, protocols, and network accounting applications and runs the Cisco IOS software. The standard (default) RSP4 configuration is 32 MB of DRAM, and the standard (default) RSP4+ configuration is 64 megabytes (MB) of DRAM. Both the RSP4 and RSP4+ have up to 256 MB of DRAM available through DIMM upgrades. DRAM is contained in up to two DIMM sockets: U10 (also called bank 0) and U13 (also called bank 1). When upgrading DRAM, you must use only compatible DIMMs. (Also see the "Compatibility Requirements" section.)

Caution   To prevent memory problems, DRAM DIMMS must be 3.3-volt (V) devices. Do not attempt to install higher-voltage devices (such as those designed for the RSP2) in the RSP4/4+ DIMM sockets.

For RSP4/4+ DRAM upgrade procedures, refer to the "Replacing and Upgrading DRAM DIMMs" section.

SRAM

SRAM provides packet buffering and CPU cache memory functions. The standard RSP4/4+ configuration is 2 MB of SRAM for packet buffering, and 512 kilobytes (KB) of secondary CPU cache memory.

Note   SRAM is fixed and is not field-upgradable.

NVRAM

The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 128-KB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of 5 years. When replacing an RSP4/4+, be sure to back up your configuration to a remote server so you can retrieve it later.

Caution   Before you replace an RSP4/4+ in a system with one RSP4/4+, back up the running configuration to a TFTP file server or to Flash memory so you can retrieve it later. If the configuration is not saved, the entire configuration will be lost—inside the NVRAM on the removed RSP4/4+—and you will have to reenter the entire configuration manually. For instructions on how to save the configuration file, see the "Saving and Retrieving a Configuration File" section. This procedure is not necessary if you are temporarily removing an RSP4/4+; lithium batteries retain the configuration in memory until you replace the RSP4/4+ in the system.

Flash Memory

The Flash memory card for the RSP4/4+ is a 16-, 20-, or 32-MB Flash memory card, which conforms to the PC Card format (formally the Personal Computer Memory Card International Association (PCMCIA) format).

Both the onboard 8-MB Flash memory and the 16-, 20-, or 32-MB Flash memory cards allow you to remotely load and store multiple Cisco IOS software and microcode images. (The 16-MB Flash memory card is the default Flash memory card that ships with the RSP4/4+.) You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You can then boot routers either manually or automatically from any of the images stored in Flash memory. Flash memory also functions as a TFTP server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory.

Caution   To prevent system problems, use Flash memory cards in the RSP4/4+ that were formatted on an RP, RSP1, RSP2, RSP7000, or RSP4/4+ running Cisco IOS Release 11.1(8)CA1 or a later release of 11.1 CA1. You cannot use Flash memory cards on the RSP4/4+ (as storage or boot devices) that were formatted on an RP, RSP1, RSP2, or RSP7000 using a Cisco IOS boot image earlier than Cisco IOS Release 11.1(8)CA1.

Table 2 lists the Flash memory card options, with the product numbers. Table 3 lists the Flask Disk options for the RSP4+.

Note   Flash memory disks are only for the RSP4+.

Flash Disks—RSP4+ Only

Note   Flash Disks are not supported on the RSP 4.

Flash Disks allow you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You can then boot routers either manually or automatically from any of the images stored in Flash memory. Flash memory also functions as a TFTP server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory.

Flash Disks are available in 64-MB, or 128-MB sizes, and can be used in slot 0, or slot 0 and slot 1.

Caution   For a Flash Disk that was formatted on an RSP8 or RSP16 to be compatible with an RSP4+, the Flash Disk must be formatted with a boot image or Cisco IOS software image compatible with the RSP4+.

For a list of compatible software releases for the Flash Disk, refer to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl.

LEDs

Figure 2 describes the operation of the LEDs found on the RSP4/4+.

PC Card Slots

The RSP4/4+ has two PC Card slots available. Either slot can support a Flash memory card. Type I and Type II PC Cards can be used in PC Card slot 0 and slot 1. Type III PC Cards can be used in slot 1. Not all Flash memory cards that are commercially available are supported.

Note   Flask Disks are supported only in the RSP4+. Up to 2 Flash Disks may be used in an RSP4+. Flash Disks are not supported on the RSP 4

Note   Other Flash memory card limitations might apply. For additional Flash memory information, refer to the Flash memory configuration notes listed in the "Related Documentation" section.

Serial Ports

Two asynchronous serial ports on the RSP4/4+, labeled Console and Auxiliary, allow you to connect external terminal devices to monitor and manage the system. The console port is an Electronics Industries Association/Telecommunications Industry Association (EIA/TIA)-232 receptacle (female) that provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.

Note   EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment (DTE) interface; the auxiliary port supports flow control and is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

Specifications

Table 5 lists the physical specifications for the RSP4/4+.

System Software

The Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX routers support downloadable system software and microcode for most Cisco IOS and microcode upgrades. This enables you to remotely download, store, and boot from a new image. For information on upgrading software and microcode in Cisco 7500 series routers, see the Cisco IOS Configuration Fundamentals Configuration Guides for the mainline software release that you are running. The Cisco IOS Configuration Fundamentals Configuration Guides are not platform-specific; however, the information in these books also pertains to the Cisco 7500 series.

Note   For the Cisco IOS releases that are supported on the RSP4/4+, refer to the "System Software" section, and to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl .

The publication Upgrading Software and Microcode in Cisco 7000 Series and Cisco 7500 Series Routers (Document Number DOC-781144) provides instructions for upgrading over the network or from floppy disks. Flash memory contains the default system software image and bundled microcode images. The Flash memory card is supported on the RSP4/4+. Flash Disks are not supported on the RSP4. Flash Disks are supported on the RSP4+.

At system startup, an internal system utility scans for compatibility problems between the installed interface processor types and the bundled microcode images. The utility then decompresses the images into running dynamic random-access memory (DRAM). The bundled microcode images then function the same as the EPROM images.

The Cisco IOS software images reside in Flash memory, which is located either on the RSP4/4+, in the form of a single in-line memory module (SIMM), or on Flash memory cards that insert in the two PC Card slots (slot 0 and slot 1) on the front of the RSP4/4+. (See Figure 2.) Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS images remotely or from software images resident in the RSP4/4+ Flash memory.

Although no monitoring of voltage or temperature is done by the RSP4/4+, a comparator device ensures that voltage is within the normal operating ranges, and three temperature sensors on the RSP4/4+ send temperature information to the chassis interface (CI) card. The CI card reports all voltage and temperature readings, and these readings are available through standard software commands for environmental monitoring. The RSP4/4+ uses a software-controlled configuration register, so you do not have to remove the RSP4/4+ to configure jumpers. There are no user-configurable jumpers on the RSP4/4+.

Comparing the RSP4 and RSP4+

The RSP4+ is an enhanced version of the RSP4 with larger default program memory (64 MB for RSP4+; 32 MB for RSP4). The RSP4+ includes Error Correction Code (ECC) memory protection; the RSP4 does not. Both versions are compatible with Cisco IOS software releases.

To determine if you have an RSP4 or an RSP4+, perform one of the following procedures:

The following example shows sample output from the show diag command with an RSP4 installed in slot 2:

The following example shows output from the show version command with an RSP4+ installed:

Electrical Equipment Guidelines

Use the following basic guidelines when working with any electrical equipment:

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, can result in complete or intermittent failures. Each processor module contains a printed circuit card that is fixed in a metal carrier.

Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use an ESD-preventive wrist or ankle strap whenever you handle any electronic system component.

Following are guidelines for preventing ESD damage:

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

Compatibility Requirements

This section describes compatibility requirements for the RSP4/4+.

Chassis Requirements

Following are chassis slot and DRAM requirements for ensuring RSP4/4+ compatibility.

Memory Requirements

Flash memory cards and DRAM DIMMs must meet the following requirements:

Table 6 shows the systems which require reformatting before the Flash memory card can be used.

Software Prerequisites

The minimum supported Cisco IOS release compatible with the RSP4/4+ is Cisco IOS Release 11.1(22)CC or a later release of Cisco IOS release 11.1 CC. For the latest compatible software releases, refer to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl .

Use the show version and show hardware commands to display the router's current hardware and software configurations. The show microcode command lists the bundled microcode (and target hardware) version for each processor type. The show controller cbus command shows the microcode version you are running. The show diagbus command shows the RSP4/4+ board's hardware version (Version 1.0 at initial release) and revision (Revision A0 at initial release).

For additional descriptions of show commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, or as printed documents.

Note   If the required system software and microcode are not available in your system, contact a customer service representative for upgrade information. (To obtain assistance, see the "Obtaining Technical Assistance" section on page 93.)

Hardware Prerequisites

Your router configuration, protocols, and features might require more than the 32 MB of DRAM (default) shipped with the RSP4 and 64 MB (default) shipped with the RSP4+. To upgrade DRAM, see the "Replacing and Upgrading DRAM DIMMs" section.

To ensure proper operation of a system configured for HSA or HA, note the guidelines below:

Microcode Requirements

Microcode 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 latest available microcode image for each processor type is bundled and distributed with the system software image.

Note   Overriding the bundle can result in incompatibility between the various interface processors in the system. We recommend that you use only the microcode image that is bundled.

List of Parts and Tools

You need some or all of the following parts and tools to install, remove, and replace an RSP4/4+ or to upgrade DRAM. If you need additional equipment, contact a customer service representative for ordering information.

Caution   To prevent memory problems, DRAM DIMMs must be 3.3-volt (V) devices. Do not attempt to install higher-voltage devices (such as those designed for the RSP2) in the RSP4/4+ DIMM sockets.

Installing the RSP4/4+

Before you begin, be sure that your system meets the minimum software, hardware, and microcode requirements described in the "Compatibility Requirements" section.

This section includes the following procedures for installing or replacing an RSP4/4+:

After the new RSP4/4+ is secure, follow the procedures in the "Troubleshooting the Installation" section to verify that it is installed and functioning properly.

Removing the RSP4/4+

Caution   Removing the only installed RSP4/4+ from a system while the system is operating will cause the system to crash. Consider this before removing an RSP4/4+ while the system is operating. To ensure that the standby RSP4/4+ operates properly with the full system configuration should the active RSP4/4+ ever fail, the standby RSP4/4+ must have the same DRAM and Flash memory capacity as the active RSP4/4+. See the "Memory Components" section for RSP4/4+ memory component requirements.

Note   The carriers on processor modules have EMI fences for EMI shielding; therefore, they fit very tightly in the chassis slots. To ensure that you can properly remove or install an RSP4/4+ in RSP slot 7, we recommend that you proceed as follows: first remove an interface processor installed in slot 8, remove or install the RSP4/4+ in RSP slot 7 (and fasten its captive installation screws as appropriate), and then reinstall the interface processor in slot 8.

When you remove or install the RSP4/4+, be sure to use the ejector levers, which help to ensure that the RSP4/4+ is fully inserted in the backplane or fully dislodged from it. An RSP4/4+ that is only partially connected to the backplane can halt the system unless a second RSP4/4+ is installed.

Figure 3 shows the ejector lever mechanism. When you simultaneously push the ejector levers inward (toward the carrier handle), the levers push the RSP4/4+ into the slot and ensure that the board connectors are fully seated in the backplane.

To remove the RSP4/4+, complete the following steps:

Step 2   Attach an antistatic strap to yourself and then connect the equipment end of the strap to a captive installation screw on an installed interface processor, or to any unfinished chassis surface.

Step 3   If you are replacing the RSP4/4+, disconnect any devices that are attached to the console or auxiliary ports. If you are removing the RSP4/4+ for maintenance and will reinstall the same one, you can leave the devices attached provided that doing so will not strain the cables.

Step 4   Use a screwdriver to loosen the two captive installation screws. (See Figure 3.)

Step 5   Place your thumbs on the ends of each of the ejector levers and simultaneously pull them both outward, away from the carrier handle (as shown in the illustration at the bottom of Figure 3c) to release the carrier from the slot and to dislodge the RSP4/4+ from the backplane.

Step 6   Grasp the handle of the RSP4/4+ with one hand and pull the RSP4/4+ straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 4.) Keep the carrier parallel to the backplane. Avoid touching the board or any connector pins.

Step 7   Place the removed RSP4/4+ on an antistatic mat or foam. If you plan to return the RSP4/4+ to the factory, immediately place it in an antistatic bag to prevent ESD damage.

Step 8   Attach the equipment end of the ESD-preventive strap to the RSP4/4+ before performing any maintenance on the RSP4/4+ that might create an ESD hazard.

This completes the removal procedure. If you removed the RSP4/4+ to replace DIMMs, proceed to the "Replacing and Upgrading DRAM DIMMs" section. If you are replacing the RSP4/4+, proceed to the next section to install the new RSP4/4+.

Replacing the RSP4/4+

Caution   Removing the only installed RSP4/4+ from a system while the system is operating will cause the system to crash. Consider this before removing an RSP4/4+ while the system is operating. To ensure that the standby RSP4/4+ operates properly with the full system configuration should the active RSP4/4+ ever fail, the standby RSP4/4+ must have the same DRAM and Flash memory capacity as the active RSP4/4+. See the "Memory Components" section for RSP4/4+ memory component requirements.

Note   The carriers on processor modules have EMI fences for EMI shielding; therefore, they fit very tightly in the chassis slots. To ensure that you can properly remove or install an RSP4/4+ in RSP slot 7, we recommend that you proceed as follows: first remove an interface processor installed in slot 8, remove or install the RSP4/4+ in RSP slot 7 (and fasten its captive installation screws as appropriate), and then reinstall the interface processor in slot 8.

The RSP4/4+ is keyed for installation only in an RSP slot. By default, the active RSP is the one that occupies the first RSP slot in the router: slot 2 in the Cisco 7507 and Cisco 7507-MX, and slot 6 in the Cisco 7513 and Cisco 7513-MX.

To install an RSP4/4+, complete the following steps:

Step 2   Place the back of the RSP4/4+ in the appropriate RSP slot and align the notches along the edge of the carrier with the grooves in the slot. (See Figure 3a.)

Caution    To prevent damage to the backplane, you must install the RSP4/4+ in one of the two RSP slots on the router. The slots are keyed for correct installation. Forcing the RSP4/4+ into a different slot can damage the backplane and the RSP4/4+.

Step 3   While keeping the RSP4/4+ parallel to the backplane, carefully slide the carrier into the slot until the RSP4/4+ faceplate makes contact with the ejector levers, and then stop. (See Figure 3b.)

Step 4   Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously push both ejector levers inward (toward the handle) until they are parallel to the faceplate. (See Figure 3c.)

Step 5   Use a screwdriver to tighten the captive installation screws on the ends of the RSP4/4+. (See Figure 3a.)

Step 6   Use a screwdriver to tighten the two captive installation screws on the RSP4/4+ faceplate to prevent the RSP4/4+ from becoming partially dislodged from the backplane and to ensure proper EMI shielding. (These screws must be tightened to meet EMI specifications.)

Step 7   If you disconnected the console terminal to remove the RSP4/4+, or if you are installing a new RSP4/4+, connect the console terminal to the console port. (See the "Connecting a Console Terminal" section.)

Step 8   Ensure that a console terminal is connected (see the "Connecting a Console Terminal" section) and that it is turned on.

Step 9   Turn the system power back on, and proceed to the "Restarting the System" section to check the installation.

Connecting a Console Terminal

The system console port on the RSP4/4+ is a DB-25 receptacle DCE port for connecting a data terminal, which you need to configure in order to communicate with your system. The console port is located on the RSP4/4+ just below the auxiliary port, as shown in Figure 5, and is labeled Console.

Before connecting the console port, check the documentation for your terminal to determine the baud rate of the terminal you are using. The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600,8N2). Use the console cable provided to connect the terminal to the console port on the RSP4/4+, and then follow the steps in the "Restarting the System" section.

Note   The console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

Connecting to the Auxiliary Port

The auxiliary port on the RSP4/4+ is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a channel service unit [CSU], data service unit [DSU], or other router) to the router. The port is located next to the console port on the RSP4/4+ and is labeled AUX. An example of a modem connection is shown in Figure 5.

Using the Y-Cables for Console and Auxiliary Connections

For systems with two RSPs installed and the HSA or the HA feature enabled, you can connect to either the console or the auxiliary ports simultaneously on both RSPs using a special, optional Y-cable.If only one RSP2 is installed, it is the system active by default.

Note   The Y-cables are not required; two individual console cables and two individual auxiliary cables can be used instead.

Figure 6 shows the console Y-cable and Figure 7 shows the auxiliary Y-cable.

Restarting the System

When you turn the system power back on, verify that the system boots and resumes normal operation. If you are restarting the system after upgrading the DRAM, expect that it will take the system longer to complete the memory initialization portion of the boot sequence with more DRAM. (See the "Verifying System Startup Sequence" section.)

Follow these steps to verify that the RSP4/4+ is installed and functioning properly:

Step 2   Observe the RSP4/4+ LEDs. While the system initializes, the CPU halt LED on the RSP4/4+ stays on. It goes off when the boot process is complete. As the RSP4/4+ initializes each interface processor, the status LEDs on each interface processor go on and off in irregular sequence.

Step 3   For a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX with HSA or HA configured, verify that the console terminal displays the system banner and startup screen as the system restarts.
