The stack LED shows the sequence of member switches in a stack. Up to four switches can be members
of a stack. The first four port LEDs show the switch member number.
first switch, which is stack member number 1. For example, if you press the Mode button and select

member numbers of other stack members. The other port LEDs are off because there are no more

When you select the Stack LED, the respective Stack LEDs are green when the stack ports (on the switch
rear panel) are up, and the respective Stack LEDs are amber when the ports are down. SFP+ module port
LEDs 1 and 2 on the switch show the status for stack ports 1 and 2, respectively.
If the port LEDs are green on all the switches in the stack, the stack is operating at full bandwidth. If any
port LED is not green, the stack is not operating at full bandwidth.
