System status LEDs
Three system LEDs are located at the bottom of the front panel that identify system status. During
POST, the switch performs internal tests and LED tests. During POST, the LEDs are lit intermittently.
After POST is successfully completed, the LEDs will behave as described in

behavior.
identifies how the system status LEDs behave when certain conditions are met. During
POST, all LEDs are lit briefly. Certain error conditions will illuminate the amber Fault LED; for
example, if temperatures exceed normal parameters. In such circumstances, power will shut off.
