Switch.7.PXM.a >

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.

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.

switch.7.PXM.a > addred 2 11 2 switch.7.PXM.a > addred 3 11 2 switch.7.PXM.a > addred 4 11 2

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.

switch.7.PXM.a > softswitch <fromSlot> <toSlot>

This step makes the secondary card active and resets the primary RPM-PR card. When the primary card resets, it loads the upgraded software defined in Step 1.

Step 4 Modify the configuration of the secondary card to boot from the new upgrade software and enter WR MEM to save the configuration.

Step 5 Enter the softswitch command, as follows, to switch to the primary card from secondary card. This command is executed only after the primary card has booted and is in the standby state.

switch.7.PXM.a > softswitch <fromSlot> <toSlot>

This step makes the upgraded primary card active and resets the secondary card. When the reset is complete, the secondary card runs the upgrade software and is now in the standby state.
