Power On a Power Supply

1. Identify the prerequisite and subsequent tasks you must perform in conjunction with this procedure, to achieve a goal.

   See the table in Servicing the Power Supplies.

2. Reconnect the power cord to the respective receptacle at the rear of the chassis.
   

   The Connected LED lights to indicate the power supply is connected to facility power.

3. Use the enablepsu command to bring the power supply to a fully powered state.

   For example, to fully power on power supply 0:

   # enablepsu 0
   Turning on 12V ...
   PSU 0, 12 V on
   #

4. Verify the power supply’s operation with the showpresent and psustatus commands.

   For example, to check power supply 0:

   # showpresent | grep PSU
   PSU 00 present, state = ON
   PSU 01 present, state = ON
   PSU 02 present, state = ON
   PSU 03 present, state = ON
   #

   # psustatus 0
   PSU 0, 12 V on
   #

5. (Optional) Display and record the power supplies FRU ID information:

   # clia fruinfo 20 FRU_number

   where FRU_number is from Component Addressing.

   The following example is the output for power supply 0:

   # clia fruinfo 20 3
