Installing a DC power supply

WARNING: To reduce the risk of electric shock, be sure that the cable grounding kit is properly installed and connected to a suitable protective earth terminal before connecting the power source to the frame.
Two lugs ship in the kit with the -48V DC power supply. The two-hole lug specification is as follows:
  • Width – 0.41 in (10.41 mm)

  • Bolt hole size – 0.20 in (5.08 mm)

  • Hole spacing – 0.63 in (16.00 mm)

Prerequisites
  • Be sure the -48V DC power cables are installed. For more information, see the HPE Synergy 12000 Frame -48V DC Power Cable Installation Instructions.

  • Be sure that a ground connection to the HPE Synergy 12000 Frame has been properly installed. See Installing the DC power grounding kit or the document that ships with the kit.

  • Gather the following tools:
    • Torx T-25 screwdriver

    • Crimper

Procedure
  1. Place the power supply on a flat, level surface.
  2. Open the input connector on the new power supply by lifting the input connector cover.
  3. Crimp a two-hole lug onto the -48V DC cable.
  4. Insert the two-hole lug through the aperture labeled "-48V" on the power supply input connector.
  5. Secure the two-hole lug to the -48V DC input connector terminal with two screws.
