Ŷ The serial port connector is only functional in a power supply that is installed in a baseplate
that also contains the CPU. The serial port is not functional on a power supply that is installed
in an expansion or remote baseplate.
Ŷ Any device connected to the serial port that uses +5 VDC power from the Series 90-30 power
supply must be included in the calculation for maximum power consumption (see “Power
Supply Loading Calculations” in Chapter 2).
CPU Serial Port Information
The serial port connector on the power supply accesses the CPU serial port, which is a feature of all
Series 90-30 CPUs. See Chapter 5, “CPUs” for information on this serial port.
