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.

To connect stacked switches:

Note: When adding a module to an existing stack, first connect the stacking cables
and then power up the module.
1 Plug the light grey connector of the Short Octaplane cable into the port marked
"to upper unit" of the bottom P330 Family module.
2 Plug 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.
3 Repeat Steps 1 and 2 until you reach the top switch in the stack.
4 If you wish to implement stack redundancy, use the Redundant Cable to
connect the port marked " to lower unit" on the bottom switch to the port
marked "to upper unit" on top switch of the stack.
5 Power up the added modules.
Caution: Do not cross connect two P330 switches with two Octaplane (light-colored)
cables. If you wish to cross-connect for redundancy, use one light-colored Octaplane
cable and one black redundancy cable. Figure 4.2 shows an incorrect connection.
