Switch is not the stack master.

Switch is the stack master or a standalone switch.

An error occurred when the switch was selecting the stack master switch, or another type of stack error occurred.

Stack LED (Catalyst 3750-X)

The stack LED shows the sequence of member switches in a stack. Up to nine switches can be members of a stack. The first nine port LEDs show the member number of a switch in a stack. Figure 1-3shows 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.
