PROCEDURE 3
Output Voltage Check
1.
Plug the AC power cord to the power supply unit, then
turn on the power.
2.
Use a multimeter to confirm that the output voltages
for the two power supply connectors conform to the
values given in table 2-1.
3.
If the voltages are within the range of values given in
table 2-1, the power supply unit is normal, but the
system board is probably defective.
Go to the system
board isolation procedures in section 2.4.
4.
If the voltages are still not within the range of
values given in table 2-1, go to PROCEDURE 4.
