MPS+1-AC Modules
Indicators
There are two LEDs on the front of
the MPS+1-AC power supply unit.
The LEDs indicate the following:
■
Left: If the left LED is constantly
lit up green, the output voltage
is +3.3 V.
■
Right: If the right LED is con-
stantly lit up green, the output
voltage is –42 V.
The LEDs only indicate that the volt-
age is present. They do not say any-
thing about the voltage quality.
Operational Information
The MPS+1-AC power supply unit
will be ready for operation as soon as
it has been plugged into the desig-
nated slot (see
Slots starting on
page 22).
The mains voltage of 230 V is drawn
through the standard IEC connector.
The output voltages are fed to the
BPV+1-12 backplane through the
96-pin spring contact strip (see
Backplane starting on page 28).
In the event of a power failure, the
power supply unit will generate a
power failure signal.
