Product Overview

The PRP-2 contains the following additional components:

•SDRAM—Up to 4 GB of Cisco-approved synchronous dynamic random-access memory (SDRAM) on two dual in-line memory modules (DIMMs). 1 GB of SDRAM is the default shipping configuration. SDRAM is field replaceable only when using Cisco-approved DIMMs.

Note Software releases prior to 12.0(30)S do not recognize more than 2 GB of SDRAM and will only use the first 2 GB of the installed memory. This does not affect the functioning of the PRP-2, but commands such as show version will indicate that only 2 GB of SDRAM are installed.

•Hard disk drive—40-GB hard disk drive can be optionally installed on the PRP-2 board.

•CF—1-GB compact flash disk can be optionally installed on the PRP-2 board.

Cisco IOS Software Storage

The Cisco IOS software images that run the Cisco 12000 Series Router system are stored in Flash memory. Two types of Flash memory ship with the PRP-1:

•Onboard Flash memory—Ships as a single in-line memory module (SIMM). This Flash memory contains the Cisco IOS boot image (bootflash) and is not field replaceable.

•Flash disk—The PRP ships with an ATA Flash disk that can be installed in either Flash disk slot. The Flash disk contains the Cisco IOS software image. Linear Flash memory cards are also supported in the PRP-1.
