Note:
The LEDs may flash different colors during diagnostic tests and POST. This does not
indicate a problem unless the LEDs do not display a healthy pattern after POST or the other
diagnostic tests are complete.
The following table describes the switch status LED on the fan side of the switch.
Interpreting POST Results
Each time the switch is powered on or reset, the switch performs POST, a system check, by default.
POST lasts a minimum of 1 minute, depending on the devices connected to the switch, and the port
status LEDs flash different colors during POST.
