Introduction
This section provides basic maintenance information for the Avaya P330 switch and
its components. For issues that are not covered in this chapter or in
"Troubleshooting the Installation," please contact your Avaya representative.
Caution: Please refer to "Before You Install the P330" before undertaking any of the
procedures detailed in this section.
Adding/Replacing an Expansion Sub-module
Caution: The expansion sub-modules contain components sensitive to electrostatic
discharge. Do not touch the circuit board unless instructed to do so.
Adding an Expansion Sub-module to 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.
