GbE NIC LEDs

Location of the LEDs for single-port GbE NICs

The following illustration shows the location of LEDs for both the copper and fiber single-port GbE NICs.

Location of LEDS on multiport GbE NICs

The following illustration shows the location of LEDs for both the copper and fiber dual-port GbE NICs. The LEDs on the quad-port GbE NIC are the same as the LEDs on the dual-port GbE NIC.

What the copper GbE NIC LEDs mean

The following table explains what the LEDs on the copper GbE NIC mean.

Note
The LEDs on the quad-port GbE NIC are the same as the LEDs on the dual-port GbE NIC.
