Check the power cord

Perform the following check on all of the power cords that the customer uses to supply power to the frame.
Note: Skip steps 2 and 3 if the power cord is wired directly to the power source.

PDU power

  1. Check all power cords for damage, broken insulation, or burned pins. Ensure that the removable plug is fully inserted in the PDU.
  2. Verify that all of the FRU power supply units (PSUs) have a cable clip installed. The cable clip is located on the handle of each PSU and secures the power cable.
  3. Verify that all delta-connected PDU power cords have the following label (L036) in place and readable:
    delta-connected PDU power cords label, L036

    This line cord uses an appliance coupler that is not intended to be mated, unmated, or moved while electrically active. Supply voltage to appliance coupler should be turned off (for example: by the supply side plug or branch circuit breaker) whenever the line cord is being plugged, unplugged, or is not attached to the product. (L036)

  4. Measure the resistance from the earth pin of the disconnected power cord to frame earth of the PDU. The reading must be 0.1 ohms or less.
  5. Check the strain relief clamp to ensure that it is correctly installed and tightly fastened.

BPA power

  1. Check all power cords for damage, broken insulation, or burned pins. Ensure that the removable plug is fully inserted in the BPA.
  2. Verify that all of the FRU power supply units (PSUs) have a Cabling Locking Assembly (CLA) safety cap installed and that the following label (L035) present and readable. The CLA is located on the handle of each PSU.

    This connection is for use only with equipment provided by the original manufacturer. Do not plug any other equipment to this connection. DC current is present on this connection. It may only be serviced by trained personnel, following product instructions closely, to ensure the correct order of operations is followed. Appliance coupler not intended to break DC current. Never connect or disconnect with power on, there is a risk of arc-flash and/or connector damage. Always ensure power is off before separating or making the connection. (L035)

  3. Measure the resistance from the earth pin of the disconnected power cord to frame earth of the BPA. The reading must be 0.1 ohms or less.
  4. Check the strain relief clamp to ensure that it is correctly installed and tightly fastened.
