Interpreting Diagnostic Indicator Lights on the System Unit
When no display appears on your monitor, you can read self-test
results by looking at the diagnostic indicator lights on the back
of the system unit. They are located between the ThinWire
Ethernet connector and the reset button.
Table 9-8 lists the error messages you might see on the
diagnostic indicator lights and tells you what they mean and
how to use them to find out what the problem is. The four
lights on the left display a pattern that tells you where the
problem is. The four lights on the right provide additional
information about the problem.
Warnings: Always shut down the worksystem software and turn the
workstation off before connecting or disconnecting a piece of hardware
and before removing the cover from the system unit or reattaching it.
Always use the antistatic wrist strap when handling memory or other
option modules, whether they are in or out of the system unit.
Chapter 4 of this guide contains instructions for removing
and replacing the cover of the system unit and for use of the
antistatic wrist strap and handling of memory and other option
modules.
