This document describes the Route Switch Processor (RSP8), an optional system processor for the Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX and Cisco 7576 routers. The RSP8 significantly increases the performance for most protocols and services over the RSP2 and RSP4/RSP4+.
The RSP8 supports the high system availability (HSA) feature, which allows two RSP8s (or an RSP8 and an RSP16) to be used in a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX router. See the "Configuring High System Availability" section for more information on HSA.
The RSP8 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.

Product Description
The topics discussed in this section are:
•
•
•
The RSP8 supports 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 1 and Figure 2.) The RSP8 is available as an upgrade to an existing RSP4, RSP2, or RSP1. The RSP8 contains the central processing unit (CPU) and most of the memory components for the router. The Cisco IOS software images reside in Flash memory, located on the RSP8:
•
•
Note
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 RSP8 Flash memory, without having to remove and replace read-only memory (ROM) devices.
The RSP8 also contains:
•
•
In addition to running the system software from DRAM, the RSP8 contains and executes the following management functions that control the system:
•
•
•
•
The high-speed switching section of the RSP8 communicates with and controls the interface processors on the high-speed CyBus. This switching section of the RSP8 decides the destination of a packet and switches it based on that decision.

1 64 MB of DRAM is the default DRAM configuration for the RSP8. The RSP8 is preconfigured with either two 32-MB DIMM or one 64-MB DIMM.
2 Do not mix memory sizes. If installing 2 DIMMs, both DIMMs must be the same size. If your router includes redundant RSPs, the RSPs should have the same memory size.
3 SRAM is not user-configurable or field-upgradable.
4 A system configuration file is contained in NVRAM, which allows the Cisco IOS software to control several system variables.
5 A 20-MB Flash memory card is the default shipping configuration for the RSP8 products.
6 The Flash Disk is offered as an option under the RSP8. You can use a Flash Disk side-by-side with a Flash memory card.
DRAM
DRAM stores routing tables, protocols, and network accounting applications and runs the Cisco IOS software. The standard (default) RSP8 configuration is 64 MB (preconfigured with either two 32-MB DIMMs or one 64-MB DIMM) of DRAM, with up to 256 MB available through DIMM upgrades. DRAM is contained in up to two DIMM sockets: U12 (also called bank 0) and U15 (also called bank 1). When upgrading DRAM, you must use DIMMs from Cisco. (Also see the "Compatibility Requirements" section.)
Caution
SRAM
SRAM provides packet buffering and CPU cache memory functions. The standard RSP8 configuration is 8 MB of SRAM for packet buffering and 2 MB of tertiary (L3) CPU cache memory.
Note
NVRAM
The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 2-MB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of 5 years. When replacing an RSP8, be sure to back up your configuration to a remote server so you can retrieve it later.
Caution
Flash Memory Cards and Flash Disks
Flash memory cards (formerly called PCMCIA cards) and 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 memory cards are available in 16-, 20-, or 32-MB sizes. Flash memory cards can be used in the RSP8 second PC Card slot for additional space, or as a backup to the main Flash memory.
Flash Disks are an alternative to the Flash memory cards, with more storage capacity. Flash Disks are available in 48-MB, 64-MB or 128-MB sizes, and can be used in slot 0, slot 1, or slots 0 and 1. You can use the Flash Disk side-by-side with the Flash memory cards.
Caution
For a list of compatible software releases for the Flash memory card and Flash Disk, refer to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl.

Serial Ports
Two asynchronous serial ports on the RSP8, 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
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 3 lists the physical specifications for the RSP8:
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. The publication Upgrading Software and Microcode in Cisco 7000 Series and Cisco 7500 Series Routers (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. Flash memory cards and Flash Disks are supported.
For the latest software release information, refer to the Software Advisor at http://www.cisco.com/pcgi-bin/Support/CompNav/Index.pl.
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 on the RSP8 in the form of a single in-line memory module (SIMM), on Flash memory cards, or on Flash Disks that insert in the two PC Card slots (slot 0 and slot 1) on the front of the RSP8. (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 RSP8 Flash memory.
Although no monitoring of voltage or temperature is done by the RSP8, a comparator device ensures that voltage is within the normal operating ranges, and three temperature sensors on the RSP8 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 RSP8 uses a software-controlled configuration register, so you do not have to remove the RSP8 to configure jumpers. There are no user-configurable jumpers on the RSP8.
Installation Prerequisites
Before beginning the installation procedures, review the following sections to ensure awareness of the appropriate regulatory and safety requirements, and to ensure that your RSP8 hardware functions properly with compatible components:

Caution
You must also format any flash disk for the RSP8 on an RSP8. Also see the Using the Flash Disk document.
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.

Installing the RSP8
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 RSP8:
•
•
•
After the new RSP8 is secure, follow the procedures in the "Troubleshooting the Installation" section to verify that it is installed and functioning properly.
Removing the RSP8
Caution
Note
When you remove or install the RSP8, be sure to use the ejector levers, which help to ensure that the RSP8 is fully inserted in the backplane or fully dislodged from it. An RSP8 that is only partially connected to the backplane can halt the system unless a second RSP8 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 RSP8 into the slot and ensure that the board connectors are fully seated in the backplane.
To remove the RSP8, complete the following steps:
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6

Step 8
This completes the removal procedure. If you removed the RSP8 to replace DIMMs, proceed to the "Replacing and Upgrading DRAM DIMMs" section. If you are replacing the RSP8, proceed to the next section to install the new RSP8.
Replacing the RSP8
Caution
Note
The RSP8 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 RSP8, complete the following steps:

This completes the procedure for replacing the RSP8.
Connecting a Console Terminal
The system console port on the RSP8 is a DB-25 receptacle DCE port for connecting a console terminal, which you need to configure in order to communicate with your system. The console port is located on the RSP8 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 RSP8, and then follow the steps in the "Restarting the System" section.
Figure 5 Console and Auxiliary Port Connections
Note
Connecting to the Auxiliary Port
The auxiliary port on the RSP8 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 RSP8 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 RSP8s installed and the HSA or the HA feature enabled, you can connect to either the console or auxiliary ports simultaneously on both RSPs using a special, optional Y-cable. If only one RSP8 is installed, it is the system active by default.
Note
Figure 6 shows the console Y-cable and Figure 7 shows the auxiliary Y-cable.
Figure 6 Console Y-Cable (Part Number CAB-RSP8CON=)
Figure 7 Auxiliary Y-Cable (Part Number CAB-RSP8AUX=)
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 RSP8 is installed and functioning properly:

When you have verified all the conditions in Step 2 through Step 6 (or Step 7 if you have a second RSP8 installed and want to use the HSA or HA features), the installation is complete. If you replaced the RSP8 and saved your configuration file to a remote server before doing so, see the "Retrieving the Configuration File" section. If you replaced the RSP8 and did not save the configuration, use the configure command or the setup facility to reenter the configuration information.
An error condition exists if no LEDs go on at power up or after initialization, or if the CPU halt LED go on and remain on. If this happens, proceed to the "Troubleshooting the Installation" section to try to isolate the problem.
For more complete configuration information, refer to the Configuration Fundamentals Configuration Guide and the Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, or as printed documents.
If you have a second RSP8 installed, you must configure the HSA (or HA, if you prefer) features for your Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX router. Read the following caution, and then proceed to the "Configuring High System Availability" section, or the "Enabling High Availability Features" section.
Caution
This completes the procedure for restarting the system.
Configuring the Router for a Single RSP8
If you have a single RSP8, you can configure your system according to the Cisco IOS release appropriate for your router. See the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware at http://www.cisco.com/univercd/cc/td/doc/product/software/index.htm.
If you have more than one RSP8 (or an RSP8 and an RSP16), and you are using a Cisco 7507 or a Cisco 7507-MX router or a Cisco 7513 or a Cisco 7513-MX router, you must configure your router for either high system availability (HSA), the default (see the "Configuring High System Availability" section), or high availability (HA) (see the "Enabling High Availability Features" section).
Using the EXEC Command Interpreter
Before you configure your system using the EXEC-level commands, you must enter the privileged level of the EXEC command interpreter using the enable command. The system prompts you for a password if one has been set. The system prompt for the privileged EXEC level ends with a pound sign (#) instead of an angle bracket (>).
At the console terminal, enter the privileged EXEC level as follows:
Step 1
Router> enablePassword:Step 2
Step 3
Router#The pound sign (#) at the system prompt indicates the privileged level of the EXEC command interpreter, from which you can execute EXEC-level commands.
This completes the procedure for using the EXEC command interpreter.
For configuration information and support, refer to the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.
Note
For troubleshooting information, refer to the "Troubleshooting the Installation" section.
Configuring High System Availability
This section describes high system availability (HSA), a feature that enables a router to continue processing and forwarding packets after a planned or unplanned outage.
It includes the following topics:
•
•
HSA is the system default when two RSP8s, or an RSP8 and an RSP16 (one designated as the "active" and the other as the "standby") are installed in a router and the active RSP8 fails. The standby RSP8 takes over in this situation, known as a "cold standby." The router restarts without manual intervention (for example, without inserting a new RSP) by rebooting with the standby RSP. The standby has its own image and configuration file and acts as a single processor.
Caution
Note
When two new RSP8s (or an RSP8 and an RSP16) are installed at the same time, the RSP that occupies the first even RSP slot on the router is the active (normally the RSP16 if the RSP8 is used in conjunction with the RSP16), and the RSP that occupies the odd RSP slot is the standby. If a crash has occurred, the RSP in the odd slot becomes the active and the RSP in the even slot becomes the standby.
HSA is supported on the following routers: Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX. HSA is not supported on the Cisco 7505 or the Cisco 7576 routers.
The cold standby procedure, from initial failure to first packet transmission, currently takes approximately eight to ten minutes.
For more complete HSA configuration information, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Configuration Fundamentals Command Reference publications, which are available online, on the Cisco Documentation CD-ROM, or as printed copies.
HSA Active and Standby Operation
During HSA operation, the active RSP8 card functions as if it were a single processor, controlling all functions of the router. The standby RSP8 card does nothing but actively monitor the active RSP8 for failure.
When the standby RSP8 detects a nonfunctional active RSP8, the standby resets itself and takes part in active-standby arbitration. Active-standby arbitration is a ROM monitor process that determines which RSP8 card is the active and which is the standby upon startup (or reboot).
If a system crash causes the active RSP8 to fail, the standby RSP8 becomes the new active RSP8 and uses its own system image and configuration file to reboot the router. The failed RSP8 card (now the standby) remains inactive until you perform diagnostics, correct the problem, and then issue the standby reload command.
With HSA operation, use the following guidelines:
•
