Upgrading Software on Redundant NRP-1s
Step 5 Use the squeeze EXEC command to permanently delete the primary NRP-1 images that are marked for
deletion.
NRPslot5# squeeze flash:
NRPslot5# squeeze bootflash:
Step 6 If you performed Step 3, use the copy EXEC command to transfer the files back from the TFTP server
to the primary NRP-1’s Flash memory.
NRPslot5# copy tftp://10.1.1.1/filename1 flash:filename1
NRPslot5# copy tftp://10.1.1.1/filename2 flash:filename2
NRPslot5# copy tftp://10.1.1.1/filename3 flash:filename3
...
Step 7 Use the dir EXEC command to verify that the new system image is the first file listed in the primary
NRP-1’s Flash memory.

Updating the Boot System Variable
If you completed the instructions in the “Updating the Boot System Variable ” section on pageB-10, then
both the primary and secondary NRP-1 configurations already reflect the new startup image.
Switch the Primary and Secondary NRP-1s
Complete the following step from the NSP to switch the primary and secondary NRP-1s. Before you
begin this task, NRPslot5 is still the primary device, and NRPslot6 is still the secondary device.
Step 1 Use the redundancy force-failover EXEC command to switch the primary and secondary devices.
Switch# redundancy force-failover slot 5
NRPslot5 is now the secondary device, and NRPslot6 is the primary device. NRPslot5 automatically
resets itself, and runs the new image in standby mode. Both the primary and secondary NRP-1s are now
running the new image.
Example—Upgrading Redundant NRP-1s
This section presents an example of upgrading redundant NRP-1 images from
CiscoIOSRelease12.0(7)DC to CiscoIOS Release 12.1(1)DC1.
The example is broken up into the following tasks:
1. Upgrading the Images on the Secondary NRP-1
2. Identifying the New Image as the Startup Image
3. Reloading the Secondary NRP-1
4. Upgrading the Images on the Primary NRP-1
5. Switching the Primary and Secondary NRP-1s
