cords or the low-voltage cords for your installation. Use the following procedure to
connect and route cables for Rack PDUs that you mounted vertically in the side of
your rack cabinet:
1. Connect one of the line cords to the main inlet on the Rack PDU. Use the line cord
that you will connect to your primary power source.
