Caution: The expansion sub-modules contain components sensitive to electrostatic discharge. Do not touch the circuit board unless instructed to do so.

Installing the Expansion Sub-module into the Avaya P330

1Remove the blanking plate or other sub-module (if installed).

2Insert the sub-module gently into the slot, ensuring that the Printed Circuit Board (PCB) is aligned with the guide rails.

The PCB not the metal base plate fits into the guide rail.

3Firmly press the sub-module until it is completely inserted into the Avaya P330.

4Gently tighten the two screws on the front panel of the expansion sub-module by turning them.

Removing an Existing Expansion Sub-module

1Loosen the screws by turning the knobs.

2Take hold of the two knobs (one near each side of the front panel) and pull gently but firmly towards yourself.

3Insert another expansion sub-module or the blanking plate.

Note: If an expansion sub-module is removed from the stack with the power supply on, all configuration definitions on expansion sub-modules are lost. To remove an expansion sub-module and save configuration definitions:

1Turn off the power supply.

2Remove an expansion sub-module.

3Insert another expansion sub-module.
