About Power Supply Connections

The AC Power Interface supplies 48V main power to the modules in the system chassis. Main power is automatically applied after (1) the AC power cords between the AC Power Interface and the customer-supplied power distribution unit (PDU) are connected, and (2) the OK power LED on the system chassis flashes.

Note

By default, the Sun Blade Server Modules do not automatically power on when the system chassis powers up. For more information see Power-On System Chassis for First Time.

The AC inlets on the Power Interface provide power to each power supply module. All power supply modules have seperate power cords.
