When the number of power inputs for the array cabinets in the equipment
room of the customer cannot meet the requirements of the 5 + 5 power
supply solution, short-circuiting processing is required for power input of
the PIUs using copper fittings. There are two locations for installing copper
fittings on a PIU. Install short copper fittings and corresponding input
power cables, and then install long copper fittings and corresponding input
power cables.
