Installation
This section presents all tasks required to install the Exalt Digital Microwave Radio.
Mechanical Configuration and Mounting
The i-Series radios are one-piece radio designs 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 standard models occupy 1 rack unit
(1RU = 1.75”/4.5cm ) height in a typical telecom rack. The -16 models occupy 1.5 RU
(2.625”/6.7cm).
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 power consumption and
ventilation for adjoining devices, they may pass heat to the device, not allowing the radio
to cool properly and increasing the risk of malfunction. Heat dissipation from the radio
may also affect adjoining devices. Provide air space above and below the device, where
possible. If not possible, a thermal analysis may be required by a professional engineer to
determine the impact of thermal transfer between all adjoining units.
Provide proper clearance for all cables and connectors attached to the device. Notably,
the RF cable connector may require significant clearance for the bend radius of the
coaxial cable assembly. Use a properly specified 90º RF connector to minimize clearance
requirements, which may be necessary in enclosure implementations. All RF connectors,
cables, and adapters must be rated for operation within the radio’s frequency range
(2400–2483.5 MHz for EX-2.4i; 4940-4990 MHz for EX-4.9i; 5250–5850 MHz for EX-
5i). RF connector losses must be accounted for within the link engineering design and
output power settings.
Rack Mounting
Rack mounting hardware for a standard 19" (48cm) rack is included in the accessory kit.
Attach the rack mounting brackets to the sides of the unit with the provided screws. The
radio can be mounted in one of four configurations:
• Front flush mount (front panel even with the rack mounting surface)
