Maintenance 

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.

Please refer to "Before You Install the P330" before undertaking any of the 

procedures detailed in this section.

Adding/Replacing an Expansion Sub-module 

The expansion sub-modules contain components sensitive to electrostatic 

discharge. Do not touch the circuit board unless instructed to do so.

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.

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.

If an expansion sub-module is removed from the stack with the power supply on, 
all configuration definitions on expansion sub-modules are lost. Both procedures for 
replacing an expansion sub-module—with saving and without saving configuration 
definitions —follow:
