Installing Expansion Sub-modules
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
1 Remove the blanking plate or other sub-module (if installed).
2 Insert 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.
3 Firmly press the sub-module until it is completely inserted into the Avaya P330.
4 Gently tighten the two screws on the front panel of the expansion sub-module
by turning them.
Note:
The Avaya P330 switch must not be operated with the expansion slot open;
the expansion sub-module slot should be covered with the supplied blanking plate
if necessary.
