7 Connecting to Power
ProST can be powered from one of the following power sources:
¾
2DC power: connected directly to a 10 - 52 DC power source
¾
2AC power: connected to a standard electrical wall outlet (110/240 VAC) using an AC/DC
power adapter
In addition, Airspan offers an optional
2third-party outdoor, lightning and surge protector that
protects the ODU-to-IDU CAT 5e cable's power and data signals from any electrical surges due to
lighting strikes.
Note: ProST is designed with a built-in lightning surge protection that
complies with the Surge Immunity standard EN 61000-4-5.
7.1 DC Power Source
ProST can be connected directly to a DC power supply unit that supplies 10 – 52 VDC (0.2 to 0.9
A; 15W maximum, assuming up to 100-m cable length between ProST and power source).
The ProST-to-DC power connectivity is supported by a splitter cable. One end of the splitter cable
connects to the ProST (using the RJ45-to-DB15 adapter or connecting directly to the 15-pin D-
type port); the other end of the cable splits into the following two wire groups:
¾ One group for the subscriber's Ethernet interface (four wires for the Tx and Rx signals)
¾ One group for the DC power source interface (two wires for +48 VDC and +48 RTN)
Caution: ProST should be powered by a safety approved Class II limited DC
power source with maximum current of 1A.
