Symptom
Possible Cause
Action
The mouse pointer does
not display on the
monitor.
The mouse is connected
incorrectly or the mouse
cable is loose.
The system is in console
mode.
The mouse is faulty.
Make sure the mouse cable is
connected correctly in the
mouse connector.
The mouse pointer displays
only when the operating
system is running. Boot the
operating system.
Replace the mouse.
Printer Problems
Verify that the printer is correctly cabled to the system (see Figure 1-3 to verify the
connection) and refer to the printer's documentation if necessary.
Overheating Problems
The system contains internal sensors that monitor system and power supply temperature
and shut down the system if maximum temperature limits are exceeded. If the system
shuts down unexpectedly:
•
Ensure that the top panel is properly in place. Refer to "Top Panel" in Chapter 5,
"Installing and Removing Components" for information on removing and replacing
the panel.
•
Verify that the ambient temperature does not exceed the limits specified in Table 2-1,
"Optimal Environmental Conditions."
•
Refer to Table 8–3, "Power Problems" to troubleshoot power supply problems and fan
failure.
Using the Fail-Safe Loader
The fail-safe loader (FSL) allows you to boot an Update Utility diskette in an attempt to
repair corrupted console files that reside within the Flash ROMs on the system board. Use
the FSL only when a failure at startup prevents you from accessing the console mode and
you have checked the operator control panel for progress messages.
