EA_Gatekeeper model 2210 Ethernet backhaul
4
The EA_Gatekeeper model 2210 is designed to operate from a 120 VAC to 277 VAC (nominal) power
supply. Power is routed through the AC line power entry gland and the wires land on the screw
terminals located on the bottom side of the SPD module. The screw terminals should be torqued to 6
inch-pounds (0.678 Newton-meters). The cable entry gland dome nut must be torqued to 20 inch-
pounds (2.26 Newton-meters).
To maintain the NEMA 4X integrity to the device, steps must be taken to ensure proper sealing of the
enclosure features. The cable used for the Ethernet communications and for powering the gatekeeper
must be a smooth, round-jacketed, outdoor rated cable. The enclosure lid screws must be installed in
the corners of a lid and torqued to 5 inch-pounds (0.565 Newton-meters). These screws are provided
in the parts bag attached to the inside of the enclosure lid. This product is equipped with an anti-
condensation heater and must configured in the field before mounted on a pole (see “Placing the
EA_Gatekeeper model 2210 into service” on page 5).
The enclosure should not be opened when ambient temperatures fall below 32 °F (0 °C). Opening the
enclosure lid when temperatures are below freezing may result in damage to the enclosure lid gasket
and compromising the seal. If the enclosure must be opened when temperatures are below freezing,
first gently warm the enclosure around the lid gasket to ensure the gasket is not frozen to the sealing
surface.
LAN communications
The gatekeeper supports different antenna options. If the antenna is mounted on the unit itself (that is,
a local external antenna), no additional steps are required when placing the gatekeeper into service.
If the gatekeeper is to be installed at a location that requires a greater height to overcome blocked
signals, a remote antenna is required.

Placing the gatekeeper into service requires mounting the
remote external antenna in a suitable location. The antenna should be mounted in the clear, as free
from conductive or metallic obstructions as possible. The connectors should be sealed for
waterproofing.
Do not use a standard RG-8/U cable with solid polyethylene dielectric. The losses in solid dielectric
RG-8/U cables in short distances make solid dielectric RG-8/U cables unacceptable.
For assemblies that use a remote mounted antenna, be sure to waterproof the RF cable terminations
(such as, using coax sealant) to help prevent water entering the cable terminations.
This device has been designed to operate with the antennas listed below and having a maximum
gain of 5.15 dBi. Antennas not included in this list or having a gain greater than 5.15 dBi are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.

help you order the correct antennas and cables.
