address lines A0 and A1 to indicate to the power supply’s EEPROM which position the power
supply is located in the server system.

The FRU circuits inside the power supply are powered off of 5VSB on the system side of the
or’ing device and grounded to ReturnS (remote sense return). The Write Control (or Write
protect) pin is tied to ReturnS inside the power supply so that server management can write to
the EEPROM.
