Warning It is critical that the power source supports the DC power requirements of your
Nodegrid. Make sure that your power source is the correct type and that your DC
power cables are in good condition before proceeding. Failure to do so could result in
personal injury or damage to the equipment.
Warning Wiring to power from a DC supply may be confusing, especially in telecom
racks, where the supply's positive wire (usually of red color) goes to the ground, and the
hot wire (usually of black color) carries the -48VDC. In case of any doubt, consult a
certified electric technician before proceeding with connections. Failure to do the right
connections could result in personal injury or damage to the equipment.
