LEDs

Switch Chassis LEDs

The BCN, STS, and ENV LEDs are located on the left side of the front of the switch. The port LEDs are appear as triangles pointing up or down to the nearest port.

LED Color Status

BCN

Flashing blue

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

Off

This module is not being identified.

STS

Green

The switch is operational.

Flashing amber

The switch is booting up.

Flashing red

Temperature exceeds 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 is connected with a transceiver or other connector.

Amber

Port is not connected.

Uplink Module LEDs

The Status (STS) LED is located on the left side of the uplink module. There is an ACT LED located below each two uplink ports. Next to each ACT LED are two triangular port LEDs that point to the top or bottom to identify their port as being the top or bottom port.
