J164 and J165 from the LVPS.
2. Turn the AC power switch On.
3. Verify the DC voltages between the
following pins on the LVPS:
P163-1 <=> P163-2 = +24
VDC?
P164-1 <=> P164-4 = +3.3
VDC?
P165-2 <=> P165-3 = +5
VDC?
P165-4 <=> P165-5 = +3.3
VDC?
4 1. Turn the AC power switch Off.
2. Connect J164 to the LVPS then turn
the AC power switch On.
