device is known as DC-Passing. It is also important that the IF frequencies of 140MHz and
350MHz be supported by the device. Proxim offers a suitable model in the price list.
Grounding Kit
To ensure good lightning protection for the radio units, install grounding kits on every 50m cable
(each 50 m for long cables) at the building entrance.
We recommend to ground the IDU to the rack cabinet and the ODU to the place, where these
units are mounted such as mast mount, pole and so on. Make special effort to ensure the ground
provides low resistance and avoid ground loops or differentials. Always obey local, state,
provincial regulations with the power and grounding of such systems.
Antennas
A variety of different antennas are available from different manufacturers and in different sizes.
Antennas can be used for horizontal and vertical polarization, the right-sided and left-sided
assembly as well. A list of qualified antennas can be found in the GX800 ordering guide. If
installing into an existing system with a non-direct mount, compatible antenna waveguide
transitions are available. Check with Proxim or your distributor to accommodate this.
Furthermore, regulatory bodies such as ETSI and FCC have strict performance requirements
which must be met by both the antenna vendor and the installer. Always make sure that the
selected antenna meets the regulatory requirements of the locale of installation.
HSI Modules
The IDU comes with a standard 10/100/1000 Gigabit Ethernet RJ45 interface along with a
10/100 Fast Ethernet RJ45 interface for management. For additional traffic interfaces, check with
Proxim for HSI modules. Proxim provides 2xE1/T1 or E3/DS3(G.703) HSI modules.
Dual IDU Mount Kit
The IDUs are designed for standard 19-inch cabinet mounting. Two IDUs can be mounted on a
single rack by using Dual IDU Mount kit.
