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:
1 Remove the power cord from the wall outlet.
2 Check 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.
3 For a stand-alone configuration:
a Remove the screws at the top and bottom of the processor module, and
remove the module from the wall.
b Mount the new module by following the steps in “Wall-Mounting a
Stand-Alone Processor Module and a 2-Slot Carrier” on page 8; then go
to Step 9.
