Replacing Modules

Replacing system modules is similar to how the modules were installed into the control unit. The procedure varies slightly between the stand-alone/2-slot carrier configuration and the 5-slot carrier configuration.

Replacing Modules in a Stand-Alone or 2-Slot Carrier Configuration

CAUTION:

Before starting, verify that you have batteries installed in the processor module by viewing the display of the telephone at extension 10.

To replace a module or modules in a stand-alone or 2-slot carrier configuration:

1Remove the power cord from the wall outlet.

2Check the slack in the wires. If there is not enough slack to remove the module without pulling the line and extension cords free, label and disconnect the wires before continuing.

3For a stand-alone configuration:

aRemove the screws at the top and bottom of the processor module, and remove the module from the wall.

bMount the new module by following the steps in “Wall-Mounting a Stand-Alone Processor Module and a 2-Slot Carrier” on page 14; then go to Step 9.
