State Meaning
On The internal power supply is working properly.
Off No power connection. The switch is NOT receiving power.
Off The normal state; indicates there are no fault conditions on the switch.
2
Flashing A fault has occurred with a component on the switch. The Status LED for
the component with the fault will flash simultaneously.
On On briefly after the switch is powered on or reset, at the beginning of
switch self test. If this LED is on for a prolonged time, the switch has
encountered a fatal hardware failure, or has failed its self test. See
chapter 4,
On The Locator LED is used to locate a specific switch in an area full of
Flashing switches. The LED can be set to be on solid or flash for a specified number
Off of minutes (1-1440). The default is 30 minutes. Use the command
"chassislocate".
On green Normal operation. The switch is ready to supply PoE power.
Flashing One or more ports has experienced a fault condition for PoE delivery. The
2
orange Fault LED will be flashing simultaneously. If it is a self test failure, the Test
LED will be flashing simultaneously. When the switch is put in PoE LED
Mode, the Mode LED for the port with the problem will also be flashing
simultaneously.
Flashing One or more ports has an alert condition for PoE delivery, for example, an
1
orange oversubscription condition (not enough PoE power available). Only this
LED will be flashing, the Fault LED is off. When the switch is put in PoE
LED Mode, the Mode LEDs for the ports with the alert condition will also
be flashing.
On green The cooling fan is operating normally.
Flashing The cooling fan has failed. The switch Fault LED will be flashing
2
orange simultaneously.
Off The normal operational state; the switch is not undergoing self test.
On green The switch self test and initialization are in progress after the switch has
been power cycled or reset. The switch is not operational until this LED
goes off. The Test LED also comes on briefly when you "hot swap" an SFP
into the switch; the SFP is tested when it is hot swapped.
Flashing A component of the switch has failed its self test. The switch Fault LED,
2
orange Test LED, and the failed component LED will flash simultaneously.
