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]] |
