Note - For residual power discharge, the power cord must remain unattached to the power supply for at least one minute before powering on a power supply.
Identify the prerequisite and subsequent service tasks you must perform in conjunction with this procedure.
Reconnect the power cord to the power supply.
The AC LED lights green to indicate the power supply is connected to facility power. A moment later, the OK LED lights green to indicate the power supply is at full power.
Verify the power supply’s operation with the checkpower and checkvoltages commands on the management controller.
For example, to check the power supplies:
# checkpower PSU 0 present status: OK PSU 1 present status: OK #
# checkvoltages Voltage ECB OK Measured 3.3V Main = 3.28 V Measured 3.3V Standby = 3.40 V Measured 12V = 12.06 V Measured 5V = 5.10 V Measured VBAT = 3.17 V Measured 1.8V = 1.78 V Measured 1.2V Standby = 1.21 V Measured 1.8V Standby = 1.80 V Measured 2.5VA = 2.51 V Measured 2.5VB = 2.51 V Measured 1.2VA = 1.22 V Measured 1.2VB = 1.21 V Measured 1.2VC = 1.21 V Measured 1.2VD = 1.21 V Measured 1.2VE = 1.21 V Measured 1.2VF = 1.21 V All voltages OK #
