    373 Both the NEC ODU and IDU are, as telecom systems, powered by a -48VDC power source. [[BR]]
    374 
    375 It is recommended that two separate -48VDC power supplies, with 110VAC feeds, be provided, one for each unit.  This avoids the need for a -48VDC distribution panel, with circuit breakers, and yet still allows individual control for each unit.  Furthermore, it allows the power supply for the ODU to be mounted in a weathertight box on the roof, if that is preferred to mounting with the indoor testbed equipment.[[BR]]

    377 Power feed connections are outlined in the [http://groups.geni.net/geni/attachment/wiki/WiMAXInteg/CampusInstallation/BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)][[BR]]

     377The power supply for the ODU can be mounted in a weathertight box on the roof (assuming a 110VAC supply is avaialble on the roof), or it can be mounted indoors, with the indoor testbed equipment.[[BR]]

    382383 * Additional outdoor power cable, two conductors, 12AWG, rated for outdoor use, for connection between the roof and the power supply, typically mounted in the equipment room
