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

LEDs
State
Meaning
Power

On
Off
The switch is receiving power.
The switch is NOT receiving power.
Fault
(orange)
Off
Flashing
†
On
The normal state; indicates that there are no fault conditions on the switch.
A fault has occurred on the switch, 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 briefly at the beginning of switch self test after the switch is powered on or reset. If on
for a prolonged time, the switch has encountered a fatal hardware failure, or has failed its
self test. See chapter 4, “Troubleshooting” for more information.
Self Test
(green)
Off
On
Flashing
†
The normal operational state; the switch is not undergoing self test.
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.
A component of the switch has failed its self test. The Status LED for that component, for
example a switch module, and the switch Fault LED will flash simultaneously.
Status/Fan
(green)
On
Flashing
†
The cooling fans are operating normally.
One or more of the cooling fans have failed. The switch Fault LED will be flashing
simultaneously.

†
A power supply is installed in the position in the back of the switch corresponding to the
number, and the supply is plugged in to an active AC power source. As shipped, the switch
has a single power supply in position 1.
A power supply is not installed in the position corresponding to the number.
The power supply installed in the position corresponding to the number is not plugged in
to an active AC power source, or has experienced a fault. The switch Fault LED will be
flashing simultaneously.
