6. Grasp the handle on the rear of the power supply and slide the power supply
forward into the power-supply bay until it clicks. Make sure that the power
supply connects firmly into the power-supply connector.
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
“Regulations” on page 75. 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.
