Connect two power cords to the AC inlets.
Use the standard power cord coming with the server and the cord coming with the power
supply unit. The POWER/STATUS lamp (green) blinks when the power cords are
connected. If the lamp does not blink, check if the power is supplied to the unit. If the
lamp remains off or the POWER/STATUS lamp goes on amber, the power cord or the
power supply unit may be defected or the power supply bay containing the power supply
unit may be failed. Contact your service representative to ask for maintenance.

Turn on the power of the server.
The POWER/STATUS lamps on the power supply units go on.

Make sure that any error on the power supply unit occurs with the STATUS lamp and
POST.
See Chapter 8 for details of error indications.
When the POWER/STATUS lamp of the power supply unit goes on amber, reinstall the
power supply unit. If the POWER/SLEEP lamp is still amber, contact your service
representative.
NOTE:
When the optional power supply unit is installed but the power
cord is connected to either of the power supply unit, the
POWER/STATUS lamp on the other unit goes on amber.
