System LEDs

System LEDs are located on the front and rear of each CPU- I ⁄ O enclosure.

The LEDs can be single-color or bicolor:

• Single-color LEDs are green, amber, or white.

• Bicolor LEDs can be green or amber.

At any time, the LEDs can also have one of three different states:

• Unlit, or OFF

• Steady on, or ON

• Blinking

You can determine the state of a particular component by interpreting the combinations

of LED colors and states. For example, you can determine if system components are

operating in duplex or simplex mode. Duplex mode means that the components are

partnered and the partner is operating properly. Simplex mode means that the partner

failed or was removed.

Tabl e 3 -1 describes the general meaning of the LED colors and states.
