Upgrading to the PRP
Upgrading to the PRP With Rebooting the Router
If for any reason you cannot use High Availability, you should use the following procedure to upgrade
from a GRP to a PRP.
Remove the Flash disk from the PRP card and install it into slot 1 of the active GRP. The following
Step 1
message will be displayed; do not format the disk.
22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a different router or PC. A
format in this router is required before an image can be booted from this device
Verify the disk contents using the dir disk1: command.
Step 2
Router# dir disk1:
Directory of disk1:/
63832064 bytes total (46465024 bytes free)
If the Cisco IOS version is not the one you need, delete the image from the disk using the delete disk1:
Step 3
filename command. If the image is correct, continue with
Use the copy tftp: disk1: command to copy onto the Flash disk the appropriate PRP image. PRP images
Step 4
are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP
image is not executable on the GRP. When prompted to abort the copy, type n.
Router# copy tftp: disk1:
Address or name of remote host [172.16.16.254]?
Source filename [c12kprp-boot-mz.120-26.4.S]? c12kprp-p-mz.120-26.4.S
Destination filename [c12kprp-p-mz.120-26.4.S]?
Accessing tftp://172.16.16.254/c12kprp-p-mz.120-26.4.S...

Abort Copy? [confirm] n
To verify that the image has been copied correctly, verify the MD5 hash for the new image on disk1:. To
Step 5
do this, use the command verify /md5 disk1image-name. The resulting string should be compared
against the MD5 hash value posted on the Software download page on Cisco.com.
Step 6 Remove any existing boot system commands from the running configuration by using the command no
boot system.
Make a note of the image name that is being used on the PRP. You can use the command dir disk1:.
Step 7
Step 8 Set the boot system command to boot the new IOS image. Note that the reference will be against disk0:.
This is deliberate. Use the command boot system flash disk0: PRP-image-name.
Save the running configuration to disk1: by using the command copy running-config disk1:
Step 9
config-name. You can check the configuration by using the command more disk1: config-name.
Note
Confirm that disk1 now contains the IOS image and configuration by using the command dir disk1:.
Step 10
The Cisco IOS image needs to be the first image on the disk.
Turn off the router.
Step 11
Remove the GRP and insert the PRP in its place.

Do not save the configuration on the GRP. In other words, do not type copy running-config
startup-config or write memory. Not saving the configuration ensures that the GRP maintains
its original configuration, which will enable you to reinstall the GRP in the future if necessary.
