Power Supply Shutdowns
Power Supply Shutdowns
If the power supply shuts down, or appears to fail at
power-on, you might have one of the following problems:
- Too many devices are set to start instantly.
See 'Setting the Motor-Start Jumper' on page 414 in the PS/2
Hardware Maintenance Manual.
- There are too many large-capacity devices installed
(such as hard disk drives).
The nominal operating current of the devices installed collectively
exceeds the available current of the power supply.
See the 'Personal System/2 Installation Planning' guide (form
number G41G-2927) for more information.
Unplug the power cord and wait two minutes before checking
voltages to give the power supply capacitors time to discharge.
NOTE:
Verify that the voltage-select switch (if applicable) is set for
the correct voltage.
If the voltages are correct and the Symptom-to-FRU index does
not solve the problem, go to Undetermined Problems on page 183
in the PS/2 Hardware Maintenance Manual.
