Off

 

Switch is not the active switch.

 

 

 

Green

 

Switch is the active switch or a standalone switch.

 

 

 

Amber

 

An error occurred when the switch was selecting the active

 

 

switch, or another type of stack error occurred.

 

 

Slow blinking green

Switch is in stack standby mode.

 

 

 

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 member number of a switch in a stack. Figure 1-5shows the LEDs on the first switch, which is stack member number 1. For example, if you press the Mode button and select Stack, the LED for port 1 blinks green. The LEDs for ports 2 and 3 are solid green, as these represent the member numbers of other switches in the stack. The other port LEDs are off because there are no more members in the stack.
