Connecting Cables to Stacking Ports
On OmniSwitch 6624, 6600-U24, and 6648 switches only, note the following important guidelines before
connecting stacking cables to stacking modules:
• Before attempting to connect OS6624, OS6600-U24, 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 and OS6600-U24) or 51 and 52 (OS6648). For detailed information on installing stacking
modules, refer to “Installing Uplink and Stacking Modules” on page 2-29.
• 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 and OS6600-U24) or 51 and 52 (OS6648).
• Do not attempt to install the stacking module at the EXPANSION slot at port positions 25 and 26
(OS6624 and OS6600-U24) or 49 and 50 (OS6648).
On all OmniSwitch 6600 series switches, note the following important guidelines before connecting stack-
ing 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 “Assigning Slot Numbers” on page 3-8
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 “Redundant Stack Connection” on page 3-13.
To connect stacking cables to stacking modules and link your OmniSwitch 6600 series 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.
