Section 4 - Installation and Configuration
4.0 Mechanical Configuration and Mounting
The EX-2.4i is a one-piece radio design intended for deployment in a telecom equipment rack
indoors or in an appropriate environmental enclosure. The device must be deployed within an
ambient temperature range as specified and properly ventilated with no obstructions to the air
intake and exhaust. The radio occupies 1 rack unit (1.75”) in a typical telecom rack.
In most cases, additional racked equipment can be placed directly above and/or below the device
with no empty spaces in the rack. However, depending on the power consumption and
ventilation for those adjoining devices, they may pass heat to the device and render the radio
unable to cool properly, which can lead to device failure. Likewise, heat dissipation from the
radio may cause adjoining devices a similar condition. With this in mind, it is desired to have
some air space above and below the device, where possible. Where this is not possible, a thermal
analysis may be required by a professional engineer to determine the impact of thermal transfer
between all adjoining units.
It is also possible to mount the device on a wall or a table.
With respect to the connections, proper clearance shall be provided for all cables and connectors
that affix to the device. Most notably, the RF cable connector may require significant clearance
for the bend radius of the coaxial cable assembly. If desired, a properly-specified 90-degree RF
connector may be used on this connector to minimize clearance requirements, such as may be
necessary in an enclosure implementation. All RF connectors, cables and adapters must be rated
for operation over 2400 to 2483.5 MHz and their losses must be accounted for within the link
engineering design and output power settings.
4.0.1 Rack Mounting the System
Rack mounting hardware for a standard 19-inch or 23-inch rack is included in the Accessory kit.
Affix the rack mounting brackets to the sides of the unit with the screws supplied. The radio may
be flush mounted or projection mounted at a variety of depths. Rack screws are not provided, use
the appropriate screw type matching your equipment rack.
