Cabling The ProST
35
CONNECTING POWER
ProST is a DC-powered device (10 – 52 VDC; 15W max. assuming up to 100-m cable length
between ProST and power source) that can be powered from one of the following power
sources:
DC power connected directly to a 48 VDC (0.5 A) DC power unit
AC power using an AC/DC power adapter connected to a standard electrical wall outlet
(110/240 VAC)
Warning: Only subscriber terminal equipment (e.g. computer modem port) that is
designed for full compliance with TNV-1 telecommunication network can be connected to
the SDA-1. Warranty of Airspan's equipment shall be made void if the SDA-1 is connected
to a computer that is not compliant with TNV-1.
Note: ProST provides a built-in lightning surge protection, complying to Surge
Immunity standard EN 61000-4-5.
DC Power Source
ProST can be connected directly to a DC power supply unit that supplies 10 – 52 VDC. The cable
setup 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). The other end of the
cable splits into two wire groups: one for the subscriber's Ethernet interface (four wires) and the
other for the DC power source interface (two wires).
Warning: The ProST should be powered by a safety approved limited DC power
source with maximum current of 1 A.
The figure below displays the ProST power supply cable setup from a DC power source.
AC Power Source
ProST can be powered from an AC power source by implementing the SDA-1, which is plugged
into a standard 110/240 VAC electrical wall outlet. In addition, the SDA-1 allows easy plug
prongs replacement to suit geographical location of electrical wall sockets (e.g. American vs.
European). The optional IDU adapters (SDA-4S Type II and SDA-4S/VL Type II) also power
ProST from the subscriber's AC electrical wall outlet. The difference between the SDA-1 and
SDA-4S Type II adapters is the method of connectivity to the power outlet, as discussed in the
subsections below.
Airspan can also provide lightning and surge protection for the SDA-1 to protect the data and
power interfaces from electrical surges caused when lightning strikes the ODU/IDU Cat 5 cable.
Using SDA-1 Type II
The SDA-1 Type II is plugged directly into a standard electrical wall outlet ((110/240
VAC). The SDA-1 Type II also allows easy plug prongs replacement to suit the
electrical wall socket (e.g. American vs. European type) of the geographical location in
which the ProST is being installed.
The AC power cabling consists of the following stages:
Changing SDA-1 Type II plug prongs
Plugging SDA-1 into wall outlet
Changing SDA-1 Plug Prongs
The SDA-1 allows you to attach plug prongs that suit the electrical wall socket of the
country in which you are installing the equipment. Therefore, before plugging the SDA-1
into the electrical outlet, ensure that the correct prongs are attached to the SDA-1.
To change the SDA-1 plug prongs:
