Adding Additional Primary Cards
You can add one or more additional RPM-PR cards as primary cards backed up by the secondary card.
To do this, enter the addred command as follows.
To do this, enter the addred command as follows.
Switch.7.PXM.a > addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
Repeat this step for each additional card you want to add to the secondary card backup protection. In the
following example, the primary cards in slots 2, 3, and 4 are being backed up by the secondary RPM-PR
in slot 11.

Upgrading Redundant RPM-PR Cards
The following procedure describes how to upgrade redundant RPM-PR cards.
Note
Redundancy must be established as described above, before you use this procedure.
Step 1
On the primary active RPM-PR card, modify the running configuration to boot from the new upgrade
software.

Step 2
Enter WR MEM to execute the write memory command, which saves the configuration.
Step 3
Enter the softswitch command, as follows, to switch to the secondary card.
