Fault/Stack Mode LED

The fault/stack mode LED shows either a fault condition or the switch stack status, depending on the Mode button selection. When the switch module is not stacked and there is no fault, the LED is off. If the switch module is stacked and the stack mode LED is selected, the stack member LED is active.

Table 1-5lists the LED colors and their meanings (only Catalyst Switch Module 3110G and 3110X).
