Stacking Switches (Optional)

Avaya P330 is a stackable switching system. Stacking involves the mounting and
connecting of stacking sub-modules in the P330 switch.

Installing the X330STK Stacking Sub-module in the P330

Caution: The stacking sub-modules contain components sensitive to electrostatic
discharge. Do not touch the circuit board unless instructed to do so.
To install the stacking sub-module in the Avaya P330:
1 Remove the blanking plate from the back of the Avaya P330 switch.
2 Insert the stacking sub-module gently into the slot, ensuring that the metal base
plate is aligned with the guide rails.
The metal plate of the X330STK (and not the PCB) fits onto the guide rails.
3 Press the sub-module in firmly until it is completely inserted into the
Avaya P330.
4 Gently tighten the two screws on the side panel of the stacking sub-module by
turning them.
Note: The Avaya P330 switch must not be operated with the back-slot open; the
stacking sub-module should be covered with the supplied blanking plate if necessary.

Connecting Stacking Sub-modules

Before attempting to connect stacking sub-modules, verify that you have the
required Octaplane cables.
Note: The two ends of the Octaplane cable terminate with different connectors. Each
connector can only be connected to its matching port.
The following cables are used to connect stacked switches:
• Short Octaplane cable (X330SC) – ivory-colored, used to connect adjacent
switches (Catalog No. CB0223) or switches separated by a BUPS unit.
• Long/Extra Long Octaplane cable (X330LC/X330L-LC) – ivory-colored, used to
connect switches from two different physical stacks, or switches separated by a
BUPS unit (Catalog No. CB0225/CB0270).
• Redundant/Long Redundant Octaplane cable (X330RC/X330L-RC) – black,
used to connect the top and bottom switches of a stack (Catalog No. CB0222/
CB0269).
