Press the reset button to reset the server and run the power-on self-test (POST).

You might have to use a pen or the end of a straightened paper clip to press the

button.

The server is designed so that LEDs remain lit when the server is connected to a

power source but is not turned on, provided that the power supply is operating

correctly. This feature helps you to isolate the problem when the operating system

is shut down.

Diagnosing problems using Easy LED Diagnostics

LEDs in two locations on the server are available to help you diagnose problems

that might occur during installation. Use them in the following order:

1. Easy LED Diagnostics panel - Look at this panel first. If a system error has

occurred, the system-error LED on the front of the Easy LED Diagnostics

drawer is lit. Slide the latch to the left on the front of the operator information

panel to access the Easy LED Diagnostics panel. Note any LEDs that are lit,

and then close the drawer.

2. LEDs on the system board - To identify the component that is causing the

error, note the lit LED on or beside the component.

Easy LED Diagnostics LEDs

The following table describes the LEDs on the Easy LED Diagnostics panel, the

problems that they indicate, and actions to solve the problems.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem

is solved.

v See the parts listing in the Hardware Maintenance Manual to determine which components are customer

replaceable units (CRU) and which components are field replaceable units (FRU).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.
