IBM Models 5 - Using the Diagnostic Processor; Understanding the Light Path Leds

2. For devices with separate test instructions, refer to those instructions when
testing.
3. When using application software, you can receive error messages that pertain
to the software. See the software manual for a description of those messages.
Using the diagnostic processor
The system unit contains a diagnostic processor that assists in the diagnosis of
common hardware field problems. This task is accomplished using:
v Diagnostic LEDs
v System Event Log Viewer
Understanding the light path LEDs
Table 12 describes the light path LEDs and the component or process each LED
represents. This table also describes the possible conditions and actions for you to
resolve the condition.
Table 12. Diagnostic processor LEDs
LED Component or process Conditions when blinking Action
2 CPU fan
v The CPU fan temperature has
exceeded 90° C.
v The fan is no longer spinning.
1. Check the CPU vent for
blockages or dust build up.
2. Ensure that the fan is plugged
into the system board.
3. Make sure that no obstacle is
preventing the fan from
spinning.
3 HDD fan
v The HDD temperature has
exceeded 60° C.
v The fan is no longer spinning.
4 HDD The HDD failed the hard disk
health check.
1. Check that the HDD
connection to the system.
Make sure that it is secured
and completely engaged in the
drive bay.
2. If the HDD presence or type
change is intended, no failure
occurred. Reset the system
event log to clear the failure.
5 Power supply The power supply input voltage is
operating outside supported
parameters.
Check the system power supply
to ensure that it is supplying the
correct and supported voltage. If
not, replace the power supply.
6 Memory A memory DIMM in the system
failed the POST memory test.
Test the memory DIMM with the
IBM Retail Store Solution
diagnostic to ensure that it is not
defective. If defective, replace.
8 Information An event has occurred and is
waiting to be cleared from the
system event log.
View the Warning/Information
attribute in the system event log.
When finished, clear the system
event log to reset the information
