Stacking Module
Stacking modules are used to connect OmniSwitch 6624, 6600-U24, and 6648 switches in a stack.
(OmniSwitch 6602-24 and 6602-48 switches have built-in stacking ports.) The stack acts as a virtual chas-
sis, with switches serving as primary and secondary management modules and Network Interface (NI)
modules. For detailed information, refer to Chapter 4, “Managing OmniSwitch 6600 Family Stacks.”
For information on installing stacking modules, refer to page 2-40. For information on removing stacking
modules, refer to page 2-42. For important installation restrictions, refer to the chassis front panel informa-
tion on pages 2-2 and 2-12, as well as “Installing Uplink and Stacking Modules” on page 2-40.
Note. Stacking modules cannot be hot swapped at any time. For more information on hot swapping, refer
to Chapter 1, “OmniSwitch 6600 Family.”

LINK/ACT LEDs
Each stacking connector has a built-in corresponding LED. This LED
indicates the link and activity status for each connector. The LED dis-
plays green when a valid cable connection exists. Flashes green as data is
being transmitted to, or received from, the adjacent switch in the stack.
HSSDC Stacking Connectors
The stacking module provides two dedicated High Speed Serial Data
Connectors (HSSDCs). These connectors are used to connect OS6624/
OS6600-U24/OS6648 switches in a stack. For detailed information on
stacks, refer to Chapter 4, “Managing OmniSwitch 6600 Family Stacks.”
