Avaya P3343T-ML manual Installing the X330STK-ML Stacking Sub-Module Optional

Chapter 4 Installation

Installing the X330STK-ML Stacking Sub-Module (Optional)

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 P334T-ML:

1Remove the blanking plate from the back of the P334T-ML switch.

2Insert 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-ML (and not the PCB) fits onto the guide rails.

3Press the sub-module in firmly until it is completely inserted into the P334T-ML.

4Gently turn the two screws on the side panel of the stacking sub-module until they are secure.

The P334T-ML must not be operated with the back-slot open. The stacking sub- module should be covered with the supplied blanking plate if necessary.

Only use the X330STK-ML stacking module with the P334T-ML.

Connecting Stacked Switches

The two ends of the Octaplane cable terminate with different connectors. Each connector can only be connected to its matching port.

You can use the following cables 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).

These are the same cables that are used with all the P330 switches.

To connect stacked switches:

When adding a module to an existing stack, first connect the stacking cables and then power up the module.

1Plug the light grey connector of the Short Octaplane cable into the port marked “to upper unit” of the bottom P330 switch.

2Plug dark grey connector of same Short Octaplane cable to the port marked “to lower unit” in the unit above. The connections are illustrated in Figure 4.3.

3Repeat Steps 1 and 2 until you reach the top switch in the stack.
