What to Do

1.Check the system LEDs.

There is a group of three LEDs located near the top left corner of the front panel and duplicated on the back panel. Their status can tell you the following.

LED

Indicates

Action

 

 

 

Locator (left)

A system administrator can

 

turn this on to flag a system

 

that needs attention.

Fault (middle)

If lit, hardware or software has

 

detected a problem with the

 

system.

Power/OK (right)

If off, power is not reaching

 

the system from the power

 

supplies.

Identify the system.

Check other LEDs or run diagnostics to determine the problem source.

Check AC power source and check the power supplies.

The Locator and Fault LEDs are powered by the system’s 5-volt standby power source and remain lit for any fault condition that results in a system shutdown.

2.Check the power supply LEDs.

Each power supply has a set of four LEDs located on the front panel and duplicated on the back panel. Their status can tell you the following.

LED

Indicates

Action

 

 

 

OK-to-Remove (top)

If lit, power supply can safely

 

be removed.

Fault (2nd from top)

If lit, there is a problem with

 

the power supply or one of its

 

internal fans.

DC Present (3rd from

If off, inadequate DC power is

top)

being produced by the supply.

AC Present (bottom)

If off, AC power is not

 

reaching the supply.

Remove power supply as needed.

Replace the power supply.

Remove and reseat the power supply. If this does not help, replace the supply.

Check power cord and the outlet to which it connects.

3.Check the fan tray LEDs.

There are two LEDs located behind the media door, just under the system control switch. One LED on the left is for Fan Tray 0 (CPU) and one LED on the right is for Fan Tray 1 (PCI). If either is lit, it indicates that the corresponding fan tray needs reseating or replacement.
