Complete the 

 for all MS-SPRing nodes 

in the network.

(Optional) Use this step only if you wish to ensure that a software revert to the previous software release 
is no longer possible. Complete the 

 again for all nodes, or groups of nodes you are upgrading. 

Complete the 

 for any nodes that are not using 

Simple Network Time Protocol (SNTP).

As needed, upgrade any spare TSC cards by installing the spare in the standby slot.

When you insert a spare TSC card in the standby slot, a software mismatch alarm is raised. The working 
software on the active TSC card is then copied to the standby TSC, causing the standby TSC card to reset. 
When the standby TSC card reset completes, the standby TSC is running the same software version as 
the active TSC card.

You can activate only one node at a time; however, you can begin activation of the next node as soon as 
the TSC cards for the current node have rebooted successfully (wait 5 minutes from the time the 
SYSBOOT alarm is raised).

Backup the Software R8.0 database, using the 

, and substituting Software R9.0 for Software R8.0.

Return to your originating procedure (NTP).

During activation, MS-SPRing spans are not protected. You must leave the MS-SPRing in the lockout 
state until you have finished activating all nodes in the ring, but you must be sure to remove the lockout 
after you have finished activating.

If you have an MS-SPRing provisioned, before beginning the upgrade you 
must perform a span lockout at each node in the ring.
The database must be backed up prior to locking the MS-SPRing.
