Do not connect the power cable without powering off the device.
Do not supply power for the device before installing the device or connecting cables.
Confirm that the grounding cable is connected properly.
Insert positive and negative poles of
the power cable into holes of the plug
and then tighten screws. (Do not
mismatch the positive and negative
poles.)
Insert the plug into the socket on the
front panel of the power card and tighten
screws to fasten the plug on the power
card. (The power card is inserted into the
chassis.)
