Installation

 

 

4If 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.

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.

You can build a stack of up to 10 P330 switches (any mixture of P330 and P330- ML modules within 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.
