LED Reference Information
Firmware Operation and Port Activity LEDs
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
Common LED States
Although the adapter LED has many possible states, the three most common are:
•Normal, that is, the link is up
•
•
Normal Link Up
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.
