Diagnostic LEDs

When a system error occurs, the relevant LEDs on the

system

board

identify

where the errors are (see “System Board

LEDs” on

Diagnostic Test Programs

The server diagnostics test programs are stored

in nonvolatile random-a

memory (NVRAM)

on

the

system board. These

programs

are the primary

me

of

them to

test some

external

devices.

 

Also,

if you

whether

is caused by the h

The server diagnostic test programs can identify most problems associ major components of your server: the system board, Ethernet controller, controller, RAM, diskette drive, serial port, parallel port, keyboard, a

You can start the diagnostic test programs from the Startup panel, w message Press F2 for Diagnostics appears. Test options let you batch groups of tests, specify test parameters (for example, which memory DIMM you and specify the number of passes that you want to run (one throug

You can also view the server
