On OmniSwitch 6624, 6600-U24, 6600-P24, and 6648 switches only, note the following important guide-
lines before connecting stacking cables to stacking modules:

• Before attempting to connect OS6624, OS6600-U24, OS6600-P24, and OS6648 switches in a stacked 

configuration, be sure that stacking modules are installed in the EXPANSION/STACKING slots of all 
switches. The stacking module provides two dedicated High Speed Serial Data Connectors (HSSDCs) 
at ports 27 and 28 (OS6624, OS6600-U24, and 6600-P24) or 51 and 52 (OS6648). For detailed infor-
mation on installing stacking modules, refer to 

• Stacking modules can only be installed in the far-right module slot. This slot is labeled EXPANSION/

STACKING and contains port positions 27 and 28 (OS6624, OS6600-U24, and 6600-P24) or 51 and 
52 (OS6648). 

• Do not attempt to install the stacking module at the EXPANSION slot at port positions 25 and 26 

(OS6624, OS6600-U24, and 6600-P24) or 49 and 50 (OS6648).

On all OmniSwitch 6600 Family switches, note the following important guidelines before connecting 
stacking cables to stacking modules:

• If you have not already individually assigned slot numbers and powered off each switch, do not 

connect stacking cables to the stacking ports. Instead, refer to 

 

and follow the instructions for assigning slot numbers to each switch. 

• Port numbers are clearly marked on the chassis front panel.

• For information on setting up stack redundancy, refer to 

To connect stacking cables to stacking modules and link your OmniSwitch 6600 Family switch into a 
virtual chassis, follow the steps below:

1 Starting from the top of the stack, attach one end of a 30 cm stacking cable to a High Speed Serial Data 
Connector (HSSDC) port, as shown.
