7. Route the power cord through the handle and cable tie if any, so that it does
not accidentally become unplugged.
8. Connect the other ends of the dc power cable to the dc power source. Cut the
wires to the correct length, but do not cut them shorter than 150 mm (6 inch).
If the power source requires ring terminals, you must use a crimping tool to
install the ring terminals to the power cord wires. The ring terminals must be
UL approved and must accommodate the wires that are described in note 118.
The minimum nominal thread diameter of a pillar or stud type of terminal must
be 4 mm; for a screw type of terminal the diameter must be 5.0 mm.
9. Turn on the circuit breaker for the dc power source to which the new power
supply is connected.
10. Make sure that the green power LEDs on the power supply are lit, indicating
that the power supply is operating correctly.
11. If you are replacing a power supply with one of a different wattage in the
server, apply the new power information label provided over the existing power
information label on the server. Power supplies in the server must be with the
same power rating or wattage to ensure that the server will operate correctly.
12. If you are adding a power supply to the server, attach the redundant power
information label that comes with this option on the server cover near the
power supplies.
