DC Power Systems

 External -48 VDC operating power for each DC-to-DC converter (mounted

in the chassis just behind the fan assembly) enters the chassis via a

dedicated DC power inlet mounted on the chassis back panel.

 The voltage input range for DC power systems is -40 VDC to -72 VDC.

 Use cable 4011730 for DC wiring. The #16 AWG wiring from the external -

48 VDC supply is attached to a 3-pin nylon connector which, in turn, plugs

into the DC power inlet.

 Order additional nylon plugs and connector pins from your preferred

supplier, as follows:

• Molex #03-12-1036 nylon 3-pin connector

• Molex #18-12-1222 crimp socket contact (3)

 Use a Molex Crimp Service Tool #63811-1000 or equivalent to crimp the

pins to the cable.
