Power On a Power Supply

1. 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.
2. Identify the prerequisite and subsequent service tasks you must perform in conjunction with this procedure.

   See Servicing Power Supplies.

3. Reconnect the power cord to the power supply.
   

   The AC LED lights green to indicate that 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.

4. Access the Oracle ILOM CLI.

   See Access the Oracle ILOM CLI (NET MGT Port).

5. Enter the restricted Linux shell.

   See Enter the Restricted Linux Shell.

6. Verify the power supply's operation with the checkpower and checkvoltages commands on the management controller.

   For example, to check the power supplies:

   FabMan@switch_name->checkpower
   PSU 0 present status: OK
   PSU 1 present status: OK
   All PSUs OK
   FabMan@switch_name->

   FabMan@switch_name->checkvoltages
   Voltage ECB OK
   Measured 3.3V Main = 3.28 V
   Measured 3.3V Standby = 3.40 V
   Measured 12V = 11.90 V
   Measured 5V = 4.99 V
   Measured VBAT = 3.01 V
   Measured 2.5V = 2.49 V
   Measured 1.8V = 1.78 V
   Measured I4 1.2V = 1.22 V
   All voltages OK
   FabMan@switch_name->
