Replacing the Stacking Sub-module

To replace the X330STK-ML stacking sub-module:

1Power to the switch may remain on.

2Loosen the screws to the stacking sub-module by turning the knobs.

3Take hold of the two knobs (one near each side of the front panel) and pull gently but firmly towards yourself.

4Insert the new stacking sub-module gently into the slot, ensuring that the metal base plate is aligned with the guide rails.

The metal plate—notthe PCB of the X330STK-ML— fits onto the guide rails.

5Press the sub-module in firmly until it is completely inserted into the Avaya P330.

Caution: Ensure that the screws on the module are properly aligned with the holes in the chassis before tightening them.

6Gently tighten the two screws on the side panel of the stacking module by turning the screws. Do not use excessive force when tightening the screws.
