b. Route the power cord through the cable management arm, or power cord
anchor, to a PDU or other suitable DC power source. Do not plug the DC
power cord into the power source.
NOTE: If using the power cord anchor, be sure to leave enough slack
in the power cord so that the redundant power supply can be removed
without disconnecting the power cord from the primary power supply.
c. Trim the DC power cord as required.
4. Connect the free end of the DC power cord to the PDU or other suitable DC
power source.
5. Connect the free end of the green/yellow safety wire to a suitable earth
ground.
IMPORTANT: If the power supply fails to operate, the blue and black
wires may be connected incorrectly. When connected properly, the
black wire should be at a higher potential (more positive) relative to the
blue wire. The power supply features reverse polarity protection so that
no damage occurs if the power supply is connected incorrectly.
