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 on page 25 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 on page 41.

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:
•In the form of a single in-line memory module (SIMM) (U1 in Figure 2)
•On up to two PC Cards (called Flash memory cards), or two Flash Disks, or a combination of PC
Cards and Flash Disks that insert in the two PC Card slots (slot 0 and slot 1)
Note For the Cisco IOS releases that are supported on the RSP8, refer to the “System Software” section on
page 9 and to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.
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:
•Most of the additional memory components used by the system, including 16-d onboard Flash
memory and up to two Flash memory cards (16-, 20-, or 32-MB Flash memory card, with a 20-MB
Flash memory card being the shipping default).
•Air-temperature sensors for environmental monitoring. (All of the logic for the environmental
monitoring functions is contained on the router interface card.)
In addition to running the system software from DRAM, the RSP8 contains and executes the following
management functions that control the system:
•Sending and receiving routing protocol updates
•Managing tables and caches

Product Description
Memory Components
Table 1 shows the memory components on the RSP8.
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 on page 13.)
Caution To prevent memory problems, DRAM DIMMS must be 3.3-volt (V) devices. Do not attempt to install
higher-voltage devices in the RSP8 DIMM sockets.
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.

Product Description
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 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 Before you replace an RSP8 in a system with one RSP8, back up the running configuration to a Trivial
File Transfer Protocol (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
RSP8—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 on page 69. This
procedure is not necessary if you are temporarily removing an RSP8; lithium batteries retain the
configuration in memory until you replace the RSP8 in the system.
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 A flash memory card must be formatted on an RSP8 if you want it to work in an RSP8.
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/cgi-bin/Support/CompNav/Index.pl.
Jumpers
There are no user-configurable jumpers on the RSP8.
LEDs
Table 2 describes the operation of the LEDs found on the RSP8:

Product Description
PC Card Slots
The RSP8 has two PC Card slots available. Either slot can support a Flash memory card or a Flash Disk.
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 or Flash Disks that are commercially available are supported.
Note Other Flash memory card or Flash Disk limitations might apply. For additional information, refer to the
“Related Documentation” section on page 2.
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 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.

Product Description
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/cgi-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.
