PCB
A949.0402
The primary power supply unit(s) as well as the frame’s backplane PCB are
directly plugged to the PSII PCB. It generates all the DC voltages required
by the frame from the 24 VDC delivered by the primary power supply unit(s),
and it constantly monitors all supply voltages. As long as everything is ok, a
relay is energized. In case of failure of any one of the supply voltages, the relay
releases. Both NO and NC relay contacts are available on the
FAN/STATUS
front panel connector
of the right-hand primary PSU only
.
The PSII PCB contains no adjustable elements.
The LED part of the PCB (not shown here) is located behind the frame’s front
panel and connected with a ribbon cable to P1 of the PSII PCB; it indicates
available/missing cards and supply voltages as well as the boot sequence and
errors while booting.
