LEDs
As described in the next three tables, there are LEDs on the switch chassis,
on the Switch Engine Module, and on the switch modules that keep you
informed of the status of the switch and the network connections.

LEDs State Meaning
Power
(green) On The switch is receiving power.
Off The switch is NOT receiving power.
Fault
(orange) Off The normal state; indicates that there are no fault conditions on the switch.
Flashing†A fault has occurred on the Switch Engine, one of the switch modules, a power supply,
or a fan. The Status LED for the module or other device with the fault will flash
simultaneously.
On On briefly at the beginning of switch self test after the switch is powered on or reset. If

†The flashing behavior is an on/off cycle once every 1.6 seconds, approximately.
LED State Meaning

(orange) Off The normal state; indicates that there are no fault conditions on the Switch Engine.
On or
Flashing†A fault has occurred on the Switch Engine. The switch Fault LED and the Self Test
LEDwillalsobeeitheronorflashingsimultaneously,dependingonthetypeoffailure.
Self Test
(green) Off The normal operational state; the switch is not undergoing self test.
On The switch self test and initialization are in progress after you have power cycled
or reset the switch. The switch is not operational until this LED goes off. The Self
Test LED also comes on briefly when you “hot swap” a module into the switch and
the module is automatically self tested.
Flashing†Acomponentoftheswitchhasfaileditsselftest.TheStatusLEDforthatcomponent,
for example a switch module, and the switch Fault LED will flash simultaneously.
Mode Select
(3 green LEDs) Act Indicates that the port Mode LEDs are displaying network activity information.
Fdx Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode.
100 Indicates that the port Mode LEDs are lit for ports that are operating at 100 Mbps.
