LEDs

Switch Chassis LEDs

The SFP port, BCN, STS, ENV, and QFP LEDs are located on the right side of the front of the switch. The SFP port LEDs appear as triangles pointing up or down to the nearest port. The Power Supply and Fan Module LEDs are located on the rear of the switch.

Status

BCN

Blue

The operator has activated this LED to identify this switch in the chassis.

Off

This switch is not being identified.

STS

Green

The switch is operational.

Flashing amber

The switch is booting up.

Amber

Temperature exceeds the minor alarm threshold.

Red

Power Supply LEDs

The power supply LEDs are located on the right portion of the power supply. Combinations of states indicated by the OK and Fault LEDs signify the status for the module as shown in this table.

OK LED

FAIL or FAIL/ID LED

Status

Green

Off

Power supply is on and outputting power to the switch.

Flashing green

Off

Power supply is connected to a power source but not outputting power to the switch. The power supply may not be properly installed in the chassis.

Off

Off

Either all the installed power supplies are not receiving power or an uninstalled power supply is not receiving power.

Off

Flashing amber

Power supply is operating but a warning condition has occurred—possibly one of these conditions:

  • High temperature

  • High power

  • Slow power supply fan

  • Low voltage

  • Power supply is installed in the chassis but was disconnected from the power source.

Off

Flashing amber (10 seconds) then amber

Power supply is installed without a connection to a power source.

Off

Amber

Power supply failure—possibly one of these conditions:

  • Over voltage

  • Over current

  • Over temperature

  • Power supply fan failure
