stalled.
To help with power cord management and prevent incorrect connections, attach labels to the power cords
and make a note of connection origins and destinations.

(1)
Connect the power cord plugs to the power inlets of the power supply units.
(2)
Fasten the plug of the power cord with the release tie.
Wrap the release tie around the power cord and fasten the release tie from either side. Make sure
that the release tie is not loose.
