 This procedure provides instructions for using manual (forced switching) and

automatic protection switching commands with the DS3 MUX and ODS2 modules. Executing
one of the Force commands forces the working or protect module online. Executing the Enable
APS or Disable APS command enables or disables Automatic Protection Switching (APS).

 A “toggle” field type means the user can press the space bar to view and select the

next option that is described; or the user can press the “R” key to view and select the
previous option. An “input” field type means the user must type an entry in the field
according to the parameters described. A “fixed” field is locked, and cannot be changed
by the user.

 Edits can be made in the configuration database in one of two ways: 1) If the

complete field is highlighted, use the space bar to toggle forward or the “R” key to
reverse toggle through the options for that field. 2) If only the first space or the field is
highlighted, type in the data that applies to that field.

 Edits to the configuration database can be saved after each change in one of two

ways: 1) Press an arrow key and then Enter or Return once; or 2) Press Enter or Return
twice

 after all selections and entries are made in the screen but before leaving the screen.

 Press CONTROL-A for help information on moving around and editing fields.

 Commands can be initiated on more than one unit by using the arrow keys to

move to each unit and pressing the space bar to select each unit.

1. Use the arrow keys to select System Maintenance from the Main Menu. Press Enter or

Return.

2. Use the arrow keys to select Force/APS Commands from the System Maintenance Menu.

3. Use the arrow keys to move to the Command field. Use the space bar to select blank space

(which means “make no changes”), FORCE TO WORKING, FORCE TO PROTECT,
Enable APS, or Disable APS for each ODS2 pair and DS3 MUX pair installed in chassis.

 Access Identifier

 Status will only appear for those units that have switching capability and are

configured as protected.

4. Assign the selections by pressing Enter or Return.
