Figure 5-34 A four-node MS-SPRing after the trunk cards are moved to different slots at one node
Procedure: Move an MS-SPRing Trunk Card
Caution Always wear an authorized electrostatic discharge wrist band when removing or installing
ONS 15454 SDH cards.
Step 1 Start CTC for one of the MS-SPRing nodes and display network view. Clear any alarms or conditions in
the network/ring. See the Check for Alarms procedure on page 5-61.
Step 2 Switch traffic away from the node where the trunk card will be moved:
a. Start CTC for the node that is connected through its east port to the target node. (In the Figure 5-33
on page 5-44 example, this is Node 1.) Click the Maintenance > Ring tabs.
b. From the East Switch list, choose FORCE RING. Click Apply.
When you perform a manual switch, a manual switch request equipment alarm (MANUAL-REQ) is
generated. This is normal.
