Troubleshooting Your System
64
A
If the date and time are not correct in the System BIOS, replace the battery
(
System Battery on page 47).
If the problem is not resolved by replacing the battery, see Getting Technical
Support on page 7.
Troubleshooting Power Supplies
c
At least one power supply must be installed for the appliance to operate. Operating
the appliance with only one power supply installed for extended periods of time
without a power-supply blank installed in the PS2 power-supply bay can cause the
appliance to overheat.
To troubleshoot power supplies:
1. Identify the faulty power supply by the power supply's status indicator ( Power
Indicator Codes on page 16).
c
If troubleshooting a power supply mismatch error, replace only the power
supply with the flashing indicator. Swapping the opposite power supply to
make a matched pair can result in an error condition and unexpected appliance
shutdown. To change from a High Output configuration to an Energy Smart
configuration or vice versa, you must power off the appliance.
2. Reseat the power supply by removing and reinstalling it ( Power Supplies on
page 31).
b
After installing a power supply, allow several seconds for the appliance to
recognize the power supply and to determine if it is working properly. The
status indicator turns green to signify that the power supply is functioning
properly.
3.
If the problem persists, replace the faulty power supply with the same type of
power supply.
If the problem persists, see Getting Technical Support on page 7.
Troubleshooting System Cooling Problems
c
Only trained service technicians are authorized to remove the appliance cover and
access any of the components inside the appliance. Before you begin this procedure,
review the safety instructions that came with the appliance.
Ensure that none of the following conditions exist:
◆
System cover, cooling shroud, drive blank, power supply blank, or front or back
filler panel is removed.
