Stack LED

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. Figure 1-8 shows the LEDs on the

first switch, which is stack member number 1. For example, if you press the Mode button and select

Stack, the port LED 1 blinks green. The LEDs for port 2 and 3 are solid green, as these represent the

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

members in the stack.

Figure 1-8 Stack L ED

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.
