OL-11636-01
When not explicitly specified, this document uses the term route processor (RP)
to indicate either the GRP or the PRP.
If you install a second, redundant RP, it must be of the same type as the primary
RP.
For information on the Performance Route Processor, see the
Processor" section on page
The GRP front view is shown in
The Cisco IOS software images that run the Cisco 12404 router reside in
Flash memory, which is located on the GRP in the form of a single inline memory
module (SIMM), and on the PCMCIA cards, called Flash memory cards, that
insert in the two PCMCIA slots on the front of the GRP. 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 12000 series routers no longer ship with GRP or GRP-B processors as
these items are now End of Sale (EOS). Refer to the the Cisco 12000 End of Life
(EOL) web page for additional information.
