PARALLEL UNITS Screen
The PARALLEL UNITS screen controls the behavior of this power source in a multi-unit
parallel system where two or more power sources are paralleled to provide higher power
level systems.
This screen is accessed from the SYSTEM SETTINGS screen using the “Parallel Units” soft key
(SK5).
Figure 6-32: PARALLEL UNITS Screen
The first field shows the number of units found at power up on the system bus. A value of 1
means this is a stand-alone unit (not part of a larger system).
The following settings can be configured on this screen:
Predefine expected units
Tells the power source how many total units to expect to
find on the system interface bus at power up. If the number
found is less than the number expected as set by the user,
one or more units may not be powered up or missing.
Leaving this check box off means the system will operate
with the number of units found, regardless.
Stand-alone unit
Set this check box if you want the power supply to operate
as a stand-alone unit, even if it is connected to the system
interface bus. To do so, you must make sure the outputs of
this power source are not connected to any other units’
outputs.
Expected parallel units
Use this field to enter then number of expected units only if
the “Predefine expected units” option is checked.
The following soft keys are available from the PARALLEL UNITS screen:
SOFT KEY
Description
Discover units
(SK1)
Re-scan the system interface bus to determine how many units
are on the bus. This also happens at power on.

Returns to the previous screen.
