3.2 Remote ON/OFF
The per PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on
the +48VDC power rail. When this signal is not pulled low by the system, or left open, the +48VDC output turns off.
The 5Vsb output remains on. This signal is pulled to a standby voltage by a pull-up resistor internal to the power sup-
ply. The power supply fan(s) shall operate at the lowest speed.
Signal Type
Accepts an open collector/drain input from the system.
Pulled-up to the 3V3sb located inside the power supply.
