Caution Traffic is not protected during a manual ring protection switch.
Step1 From the View menu, choose Go To Network View.
Step2 Click the Provisioning > MS-SPRing tabs.
Step3 Choose the MS-SPRing and click Edit.
Tip To move an icon to a new location, for example, to see MS-SPRing channel (port) information more
clearly, click an icon, and drag and drop it in a new location.
Step4 Right-click any MS-SPRing node channel (port) and choose Set West Protection Operation (if you
chose a west channel) or Set East Protection Operation (if you chose an east channel).
Note The squares on the node icons represent the MS-SPRing working and protect channels. You can
right-click either channel. For four-fiber MS-SPRings, the squares represent ports. Right-click
either working port.
Step5 In the Set West Protection Operation dialog box or the Set East Protection Operation dialog box, choose
MANUAL RING from the drop-down list. Click OK.
Step6 Click Yes in the two Confirm MS-SPRing Operation dialog boxes.
Step7 Verify that the channel (port) displays the letter “M” for Manual ring. Also verify that the span lines
between the nodes where the Manual switch was invoked turn purple, and that the span lines between all
other nodes turn green on the network view map. This confirms the Manual switch.
Step8 From the File menu, choose Close.
