8-Slot Chassis - 3Com NETBuilder II Installing Instruction

To determine the total load on the 4-Slot chassis power supply, add the
maximum current consumption of the floppy disk drive, the main processor
module, and each installed I/O module. For the maximum current consumption
of the main processor module and each installed I/O module, refer to each
installation guide.
