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.

Note: You can build a stack of up to 10 P330 switches (any mixture of P330 and

P330-ML modules wihin a stack is possible). If you do not wish to stack all the

switches in a single rack, use long Octaplane cables to connect two physical stacks

as shown in Figure 4.3.
