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 Octaplane cable (X330LC) – ivory-colored, used to connect switches from
two different physical stacks, or switches separated by a BUPS unit (Catalog No.
CB0225).
• Redundant cable (X330RC) – black, used to connect the top and bottom
switches of a stack (Catalog No. CB0222).
To connect stacked switches:
1 Plug the light grey connector of the Short Octaplane cable into the port marked
“to upper unit” of the bottom Cajun P330 switch.
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.
Note:
If you have split the stack, use the Long Cable instead of the Short Cable
where required.
4 If you wish to implement stack redundancy, use the Redundant Cable to
connect the 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 Cajun P333T 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 Cajun P330 switches. 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.
