Diagnostic Leds - HP zx2000 Technical Reference Manual

diagnostic LEDs

The four diagnostic LEDs on the front bezel of the system are used for diagnosing the health of
the system. These LEDs warn of impending hardware failures and allow you to take preventive
action, such as making a system backup or replacing a component before it fails. These
diagnostic LEDs are labeled 1, 2, 3 and 4.
The location of red LEDs can be used to identify the category of the fault or warning. For
example, if LED one is red, there is a problem with memory. However, if LEDs one and two are
both red, there is a problem with the system processor.
If the diagnostic LEDs indicates an error, check the SEL (page D-4) for a more detailed
explanations of the failure.
The following symbols are used in the LED tables.
