Switch Chassis LEDs
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
1
A fault has occurred on the switch, one of the switch modules, an individual port, a power
supply, or a fan. The Status LED for the module or other component 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 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
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
1
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
The cooling fans are operating normally.
Flashing
1
One or more of the cooling fans have failed. The switch Fault LED will be flashing
simultaneously.
Status/Power
(green -
numbers
corresponding
to the power
supply
positions)
On
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.
Off
A power supply is not installed in the position corresponding to the number.
Flashing
1
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.
Status/
Modules
(green - letters
corresponding
to the switch
module slots)
On
A module is installed in the switch module slot corresponding to the letter and the module
is undergoing or has passed self test. This also occurs when you install a module when
the switch is already powered on (“hot swap”).
Off
A module is not installed in the switch module slot corresponding to the letter.
Flashing
1
The module status LED flashes very briefly when a module is being hot swapped. If the LED
flashes for a prolonged time, the module in the slot corresponding to the letter has failed
self test or encountered some other fault condition. See chapter 4, “Troubleshooting” for
a more information.
