Power Share Backplane

The power share backplane distributes the power load of the system among two or three power supplies. The backplane is mounted on two snap-on standoffs and six threaded standoffs on the center wall inside the chassis.

▲WARNINGS

The power button on the front panel of the system does not turn off the AC power. To remove AC power from the system, you must unplug the AC power cord from each power supply or wall outlet.

Hazardous voltage, current, and energy levels are present inside the power share backplane. There are no user serviceable parts inside it; servicing should be done only by technically qualified personnel.
