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 P332G-ML:
1 Remove the blanking plate from the back of the P332GP332G-ML 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-ML (and
not the PCB) fits onto the guide rails.
3 Press the sub-module in firmly until it is completely inserted into the
P332GP332G-ML.
4 Gently turn the two screws on the side panel of the stacking sub-module until
they are secure.
Note: The P332GP332G-ML must not be operated with the back-slot open. The
stacking sub-module should be covered with the supplied blanking plate if necessary.
Note: Only use the X330STK-ML stacking module with the P332GP332G-ML.
Connecting Stacked Switches
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).
These are the same cables that are used with all the P330 switches.
