Removing/Replacing Modules

Removing a Module

To remove a processor or 206 module:

1.Disconnect the AC power cord from the wall outlet.

2.Remove the control unit cover by sliding it directly off the backplane.

3.Grasp the front top of the module with one hand while holding down the locking tab at the base of the module with the other hand. With the locking tab down, put one finger of the same hand in the wire bracket on the bot- tom front of the module. Using both hands, pull the module forward and out, being careful not to strain the wires connected to the module. (If there is not enough slack in the wires, label and disconnect them before remov- ing the module. )

WARNING: There are no field-serviceable components inside the 206 modules or backplane. Hazardous voltages within. DO NOT OPEN THE MODULES!

Replacing a Module

To replace a defective processor or 206 module:

1.Complete the steps above for removing the module.

2.Disconnect the first telephone line from the old module and connect it to the new module. Repeat for the second telephone line (if applicable).

3.Disconnect the first extension line from the old module and connect it to the new module. Repeat for the other extensions.

4.Insert the new module as described on page 2-2.

5.Connect the AC power cord. The system performs the necessary reset procedures automatically. You should not need to reprogram the system unless you replaced the processor module, or unless you added or removed telephone lines and/or extensions when replacing the 206 modules.
