Jumpers, LEDs | Cisco Systems RSP8 specification

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.
