Product Overview

Cisco IOS Software Storage

The Cisco IOS Software images 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 CompactFlash disk

slot. The CompactFlash disk contains the Cisco IOS software image. Linear flash memory cards are

also supported in the PRP-1.

The PRP-2 provides the following additional flash memory:

• CompactFlash (CF) disk—Optional 1-GB CF disk can be used for large Cisco IOS images.

Storing the Cisco IOS images in flash memory enables you to download and boot from upgraded

Cisco IOS software images remotely, or from software images that reside in PRP flash memory.

Cisco 12000 Series Internet Routers support downloadable system software for most Cisco IOS Software

upgrades. This enables you to remotely download, store, and boot from a new Cisco IOS software image.

The Cisco IOS software runs from within the SDRAM of the PRP.

Cisco IOS XR Software Storage

The PRP-3 provides the following compact flash memory for storing the Cisco IOS XR software image:

• Internal CompactFlash (CF) on board—(compact flash:) 2-GB internal compactflash is used for

large Cisco IOS XR software images.

• External CompactFlash (CF)—(disk0:) 2-GB external compactflash is used for large Cisco IOS XR

software images. The external CompactFlash can be inserted from the front panel of PRP-3.

External CompactFlash replaces the PCMCIA slots of PRP-2.

Cisco IOS XR software images remotely, or from software images that reside in PRP-3 flash memory.
