Figure 3-13. Stacking Module LED Indicators

The Link and Act LEDs have the same function as the corresponding LEDs for the switch’s Ethernet ports. The Link LED lights to confirm a valid link, while the ACT LED blinks to indicate activity on the link.

The Stack No. seven-segment LED displays the Unit number assigned to the switch. A 0 (a zero) 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.

The stacking order can be automatically configured using the switch’s MAC address the lower the numerical value of a given switch’s MAC address, the lower the number in the stacking order the switch will be assigned. The switch with the lowest MAC address, will then become the Master Switch. This is the Stacking Module’s default mode.

Alternatively, the stacking order can be manually assigned using the console’s Command Line Interface (CLI).
