Step 3 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 on the Edit MS-SPRing network graphic and while pressing Ctrl, drag the icon to

a new location.

Step 4 To lock out a west span:

a. Right-click any MS-SPRing node west channel (port) and choose Set West Protection Operation.

Figure 19-4 shows an example.

Note For two-fiber MS-SPRings, 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.

list. Click OK.

c. In the Confirm MS-SPRing Operation dialog box, click Yes . An “L” indicating the lockout appears

on the selected channel (port) where you invoked the protection switch.

Performing a lockout switch generates LKOUTPR-S and FE-LOCKOUTOFPR-SPAN conditions.

b. In the Set East Protection Operation dialog box, choose LOCKOUT SPAN from the drop-down list.
