Emulex Adapters User Manual

 

Emulex adapters have a POST test. Each port has a set of green and yellow LEDs (visible through 
openings in the adapter's mounting bracket) that indicate the conditions and results of the POST. 

•

Green = firmware operation

•

Yellow = port activity 

Adapter LEDs also identify possible problems. For more information on LED states, see Table 1 on 
page 20. 

LEDs can help you locate:

•

Bad cables

•

Bad transceivers

•

Bad switches or hub ports

LEDs can help you determine whether:

•

The switch or hub is on

•

The driver is loaded

•

The driver reset the adapter

Although the adapter LED has many possible states, the three most common are:

•

Normal, that is, the link is up

•

Link-down or adapter waiting

•

Heart-beat indication

A normal link up means that the driver is loaded and talking to the switch. Everything is operational. 

1 Gb/s link up:

•

For 1Gb/s adapters, a normal link up state is indicated with a solid green LED and a slow 
blinking (1 Hz) yellow LED. 

•

For 2 Gb/s adapters, a solid green LED and a slow blinking yellow LED.

•

For 4 Gb/s adapters, a solid green LED and a single blinking yellow LED.

2 Gb/s link up:

•

For 2 Gb/s adapters, a solid green LED and a fast blinking yellow LED.

•

For 4 Gb/s adapters, a solid green LED and a double blinking yellow LED.

•

For 8 Gb/s adapters, a solid green LED and a fast double blinking yellow LED.
