The IDU‐H: A Base Station Alternative to PoE Devices
Using an IDU‐H instead of several PoE devices
The IDU‐H is an aggregation switch with the functionality of six PoE devices. It is ideal for use
at a base station having several collocated HSUs or RADWIN 2000 radios.

Installing an IDU‐H
The IDU‐H can sit on a table top, but is best installed in a rack using the supplied ears as in
Figure 4‐11 and Figure 4‐12.
Connecting the HBS to an IDU‐H
Connect the HBS IDU port to any of the six PoE ports of the IDU‐H.
Connecting the IDU‐H device to a network
The IDU‐H has two LAN ports, either of which may be used for network connection.
Grounding and Powering Up the IDU‐H
The IDU‐H has redundant power connection circuits. An enlarged view of the power
connectors is shown in below:
Figure 4‐34: IDU‐H power connectors, grounding lug and power plug.
• For direct DC connection: The connectors are 3 pin in line female, with polarities (left to
right) minus, ground, plus.
• For AC connection: To avoid damage to the IDU‐H, always use an AC/DC adapter and
power plug supplied by RADWIN.
Ground the unit with a 10 AWG wire before applying power.
