Stacking LED Indicators
Stacking LED indicators include the Stack ID indicator on the front panel and the Link/Act indicators on the
front of the DES-332GS stacking module.
Each stacking module has Link and Act LED indicators on its front panel for the IEEE 1394 IN/OUT pair and
the GBIC port.

The ACT LED blinks to indicate activity on the link.
STACK NO.
The Stack Number seven-segment LED displays the Unit number assigned to the
Switch. A zero (0) in the display indicates that the stacking module is in the process
of determining the stack status and has not yet resolved the Switch’s Unit number.
NOTICE:
Do not connect the stacked Switch group to the network until you have
properly configured all Switches for stacking. An improperly configured Switch
stack can cause a broadcast storm.
