Chapter 1 Product Overview

Route Processors

Note GRP route memory configurations of 512 MB are compatible with only Product Number GRP-B=. Cisco IOS Release 12.0(19)S or 12.0(19)ST or later, and ROMMON Release 11.2 (181) or later are also required.

•SRAM—512 kilobytes (KB) of static random-access memory (SRAM) for secondary CPU cache memory functions. SRAM is not user configurable or field upgradeable.

•NVRAM—512 KB of nonvolatile RAM (NVRAM). NVRAM is not user configurable or field upgradeable.

•Memory—Most of the additional memory components used by the system, including onboard Flash memory and up to two Personal Computer Memory Card International Association (PCMCIA)-based Flash memory cards and Advanced Technology Attachment (ATA) Flash disks.

The GRP is shipped with 20 MB of Flash memory as the default configuration.

•Sensors—Air-temperature sensors for environmental monitoring.

Note The GRP memory options and instructions for upgrading memory are described in the Cisco 12000 Series Gigabit Switch Router Memory Replacement Instructions (Document Number 78-4338-xx).

The Cisco IOS software images for operating the router reside in Flash memory on the GRP. The Flash memory can be either the single in-line memory module (SIMM) on the GRP or a PCMCIA Flash memory card that inserts into either PCMCIA slot 0 or slot 1 (labeled SLOT-0 and SLOT-1) on the front of the GRP. (See Figure 1-5.)

Note The GRP Flash memory SIMM contains the Cisco IOS software boot image, and a PCMCIA Flash memory card contains the Cisco IOS software image.

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 GRP Flash memory. The Cisco IOS software runs from within GRP DRAM.
