STS

Green

The switch is operational.

Flashing amber

The switch is booting up.

Amber

Temperature exceeds the minor alarm threshold.

Red

Temperature exceeds the major alarm threshold.

Off

The switch is not receiving power.

ENV

Green

Fans and power supply modules are operational.

Amber

At least one fan or power supply module is not operating.

(port)

Green

Port admin state is 'Enabled', SFP is present and the interface is connected (that is, cabled, and the link is up).

Amber

Port admin state is 'Disabled, or the SFP is absent, or both.

off

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

Flashing amber

Power supply is operating but a warning condition has occurred—possibly one of the following 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

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

Amber

Power supply failure—possibly one of the following conditions:

  • Over voltage

  • Over current

  • Over temperature

  • Power supply fan failure.
