Step 6 Ensure that the previously standby NSC is now active and that the NSC in <logicalSlotNumber> is
now in standby state.
Step 7 For an MGX 8260 configured for NSC redundancy, force a switchback to the NSC indicated in Step 3.
Use the swcd command:
swcd <standbySlotNumber>
Where <standbySlotNumber> is the number of the standby/redundant NSC (currently in active state).
Step 8 Repeat Step 3 through Step 7 for all NSCs in your system.
Note If the NSC does not have a back card, it may reboot in MISMATCH state. Fix this by entering the
command chcdif <logicalSlotNumber> 3. This returns the NSC to No-Back-Card mode.
Database Configuration Information
You do not need to clear the configuration database when performing a graceful upgrade from Release
1.2.2, 1.2.3, or 1.2.4 to Release 1.2.5. Nongraceful upgrades require a database reconfiguration.
