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.
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.
