Route Switch Processor (RSP8) Installation and Configuration Guide
OL-4920-02
Installation Prerequisites
–
12.1(0) or a later release of Cisco IOS Release 12.1
–
12.1(2)E or a later release of Cisco IOS Release 12.1 E
Note
You can reboot from a Flash memory card or Flash Disk in the RSP8 that was previously formatted on
an RSP4+.
•
You must first reformat the Flash memory card or Flash Disk on an RSP8, that was previously
formatted on one of these other RSP-based systems, before you can use it as a boot or storage source
with the RSP8. Refer to
Flash Memory Card Installation Instructions
(part number DOC-782083=)
for instructions on reformatting a Flash memory card. Refer to
Using the Flash Disk
(part number
DOC-785819=) for instruction on reformatting a Flash Disk.
Software Prerequisites
The minimum supported Cisco IOS release compatible with the RSP8 is release 12.0(5)T or a later
release of Cisco IOS release 12.0 T. For the latest compatible software releases, refer to the Software
Advisor at
http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.
Note
The 32-MB Flash memory card is compatible with Cisco IOS Release 12.1(5)T1 or a later release of
12.1 T.
Use the show version and show hardware commands to display the router’s current hardware and
software configurations. The show microcode command lists the bundled microcode (and target
hardware) version for each processor type. The show controller cbus command shows the microcode
version you are running. The show diagbus command shows the RSP8 board’s hardware version and
revision.
For additional descriptions of show commands, refer to the Configuration Fundamentals Configuration
Guide and Configuration Fundamentals Command Reference publications, which are available online,
on the Documentation CD-ROM, or as printed documents.
Note
If the required system software and microcode are not available in your system, contact a customer
service representative for upgrade information. (To obtain assistance, see the
“Obtaining Technical
Assistance” section on page 89
.)
Hardware Prerequisites
Your router’s configuration, protocols and features might require more than the 64 MB of DRAM that is
shipped with the RSP8. To upgrade DRAM, see the
“Replacing and Upgrading DRAM DIMMs” section
on page 74
.
To ensure proper operation of a system configured for HSA or HA, note the guidelines below:
•
With HSA and HA, the RSP8 can interoperate with another RSP8, or with an RSP16.
•
To ensure that the standby RSP8 operates properly, the active and the standby RSP8 (or the RSP8
and the RSP16) should have the same DRAM configuration and boot ROM version.
•
Removing the active RSP8 while the system is operating might cause the system to crash; however,
the system reloads with the standby RSP8 as the new active RSP8. To prevent system problems, do
not remove the active RSP8 while the system is operating.
