March 2005 Completing a Stacked Configuration 27

Connecting Cables

to Stacking Modules

Guidelines

• If you have not already individually assigned slot

numbers and powered off each switch, do not connect

stacking cables to the stacking modules. Instead, refer to

“Assigning Slot Numbers” on page 25 and follow the

instructions for assigning slot numbers to each switch.

• Before attempting to connect OmniSwitch 6600 Family

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, OS6600-P24,

OS6602-24) or 51 and 52 (OS6648 and OS6602-48). For

detailed information on installing stacking modules, refer

to “Installing Uplink and Stacking Modules” on page 16.

• Stacking modules can only be installed in the far-right

module slot. This slot is labeled EXPANSION/STACK-

ING and contains port positions 27 and 28 (OS6624 and

6600-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,

OS6600-U24, OS6600-P24, OS6602-24) or 49 and 50

(OS6648 and OS6602-48).

• Port numbers are clearly marked on the chassis front

panel.

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) located on the switch’s stacking

module, as shown.
