  7. Route the power input lead cords between the rear RETMA rail and the side panel.

    A PDU has one power input lead cord, which you must route between the side panel and the rear RETMA rail.

    Route the power input lead cord either down through the bottom of the rack, or up through the top of the rack, depending on where you plan to connect them to the main power source.

    If you are routing the cables through the bottom of the rack, refer to the Sun Rack II User's Guide for the dimensions of the floor cutout.


    Caution

    Caution  -  Never twist, kink, or tightly bend a power input lead.
