View of DC Power Cords
The DC power cord has a connector only for the server end. Therefore, a terminal
matching the DC power supply equipment will need to be attached to the DC power
supply end of the cord.
C.1.3 Facility Power Requirements
The power supply that can be used with the M3000 server is restricted to DC power
supply equipment that is separate from the AC power, or DC power supply
equipment that has double or reinforced insulation for high, dangerous voltages.
Always mount overcurrent protective devices between the DC power supply
equipment and the M3000 server. One overcurrent protective device is required for
each power supply line. The overcurrent protective devices must comply with the
following specifications:
■
Current rating: 30 A
■
Voltage rating: at least 65 Vdc
■
Operation type: Immediate shutdown type (however, overcurrent protective
devices should not operate against 1 ms rush currents with a peak current of
100 A)
■
Number of poles: 2 (-48 Vdc to -60 Vdc line and RTN line)
