Step 1 From the View menu, choose Go to Network View.

a new location.
Step 4 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.

other nodes turn green. This confirms the Manual switch.
Step 8 From the File menu, choose Close.
