No.

LED

Icon or Label

Description

Locator LED and

button (white)

You can turn on the Locator LED to identify a particular server.

When lit, the LED displays as a fast blink. The blinking will time

out after 15 minutes. Turn on the Locator LED by pressing the

Locator button, or see

“Locate the Server” on page 49

System Faulit

(Service Action

Required) LED

(amber)

The

fmadm

faulty

command provides details about any

faults that cause this indicator to light. See

“Check for

Faults” on page 33

Under some fault conditions, individual component fault LEDs

are lit in addition to the Server Service Required LED.

Power OK LED

(green)

Indicates these conditions:

■

Off

– Server is not running in its normal state. Server power

might be off. The SPM might be running.

■

Steady on

– Server is powered on and is running in its normal

operating state. No service actions are required.

■

Fast blink

– Server is running in standby mode and can be

quickly returned to full function.
