The power supply is a field replacea-
ble unit (FRU) and is located in the
electronics module. The back panel of
the power supply is electronic panel 2
(Figure 6-10). Located on panel 2 are
the sockets for AC power in, switched
AC power out (to the diskette module
or the large display) DC voltage for
communications, and the primary fuse.
The power supply provides the follow-
ing DC voltages and currents to the
system:

To prevent power supply and machine
damage, overvoltage and undervoltage
protection circuits control the DC
voltages. If· any DC voltage level is
under or over the voltage limits, the
power supply will internally switch
off. An overcurrent protection cir-
cuit is also supplied. It will cause
a switch-off to occur if the combined
current outputs are more than the pow-
er supply limits. Because the
overcurrent protection controls the
combined current flow in the power
supply, a single DC circuit overcur-
rent may not cause an overcurrent
switch-off. Overvoltage, undervoltage
and overcurrent swi tch -off logic may
be reset by turning the power switch
off, then on.
A thermal protection circuit located
inside the power supply protects the
power supply and electronics from dam-
age caused by too much heat. A fan in
the power supply is used to distribute
air through the electronics module to
provide cooling. A thermal sensor
will cause a thermal switch-off if the
power supply overheats. A thermal
switch-off can be reset by turning off
the power switch and permitting the
electronics module to cool.
