Cisco Cisco ONS 15600 Multiservice Switching Platform (MSSP) 安装指南

You can only activate one node at a time; however, you can begin activation of the next node as 
soon as the controller cards for the current node have rebooted successfully (wait 5 minutes from 
the time when the SYSBOOT alarm is raised). The database must be backed up prior to locking 
the BLSR.

(Optional) If you wish to ensure that a software revert to the previous software release will no longer be 
possible, complete the

 to accept the load.

As needed, upgrade any spare TSC cards by installing the spare in the standby slot of a Software R8.0 
node.

When you insert a spare TSC card in the standby slot, a software mismatch 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.

To back up the Software R8.0 database for the Working software load, see 

 in order to preserve the database for the R8.0 software.

During activation, BLSR spans are not protected. You must leave the BLSR 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. The database must be backed up prior to locking the BLSR.

To prevent ring or span switching, perform the lockout on both the east and west spans of each node.

If you have a BLSR 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 BLSR.
