Product Overview
The PRP-2 provides the following additional Flash memory:
• Compact Flash (CF) disk—Optional 1 GB CF can be used for large 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 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.
For specific Cisco IOS software requirements for the PRP, see the “Cisco IOS
Software Requirements” section on page 3.
