Use the standard power cord coming with the server and the cord coming with the power supply unit. The

cord or the power supply unit may be defective or the power supply bay containing the power supply unit may
have failed. Contact your service representative to ask for maintenance.

POWER 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/FAIL lamp on the other unit goes on amber.
