Alcatel-Lucent 6600 manual Connecting the Switches in the Stack

Setting Up a Stacked Configuration Managing OmniSwitch 6600 Family Stacks

2Next, attach the other end of the cable to a HSSDC connector on the switch immediately below. Repeat this procedure until all switches in the stack are connected (see illustrations a, b, and c below).

Connecting the Switches in the Stack

Note. There are no restrictions on which HSSDC stacking ports must be connected. For example, a stack- ing cable connected to port 51 on an OS6648 may be connected to either port 51 or port 52 on the OS6648 immediately below. However, for easier management, it is recommended that you keep a consistent pattern for all switches in the stack.

3To provide added resiliency and redundancy, it is strongly recommended that you install the optional one-meter stacking cable to connect the top switch in the stack to the bottom switch in the stack. Use the unused HSSDC stacking connectors located at ports 27 and 28 (OS6624, OS6600-U24, OS6600-P24, and OS6602-24) or 51 and 52 (OS6648 and OS6602-48) of each switch, as shown. For more information on stack redundancy and the one-meter stacking cable, refer to “Redundant Stack Connection” on page 4-13.

Note. The one-meter stacking cable is available with Alcatel’s optional Redundant Stacking Kit.

Recommended Redundant Connection Between Switches

4Now that all switches in the stack are connected, continue to “Booting the Stack” on page 4-14.
