The amount of current/power that can be supplied to the Units mounted in a
Rack is limited by the capacity of the Rack's Power Supply Unit. Refer to the
following tables when designing your system so that the total current con-
sumption of the mounted Units does not exceed the maximum current for
each voltage group and the total power consumption does not exceed the
maximum for the Power Supply Unit.
The following table shows the maximum currents and power that can be sup-
plied by Power Supply Units in CPU Racks and Expansion Racks.
When calculating current/power consumption in a CPU Rack, be sure to
include the power required by the CPU Unit itself, as well as the I/O Control
Unit if one or more Expansion Racks is connected. Likewise, be sure to
include the power required by the I/O Interface Unit when calculating current/
power consumption in an Expansion Rack.
