The single-band RU enclosure is hanging-mounted on the mounting bracket.
3.3.2.3 RF Connection
The RF signal connections with the single-band enclosure are supported through two SMA female coaxial
connectors and one 7/16” DIN female connector. The two SMA female connectors are used for coaxial cable
connection (RF jumper) of the Tx and Rx RF signals between the CM-BTS/ANT enclosure and the
single-band RU enclosure. The 7/16” DIN female connector is used for coaxial cable connection of the
amplified duplex Tx/Rx RF signal to the CM-BTS/ANT enclosure.
3.3.2.4 Cooling
The single-band RU enclosure is cooled by continuous air flow fans mounted on the top of the casing. A
minimum of 200mm (7.87 inches) of clearance space must be provided on both the top and the bottom
sides of the Remote Node for air convection.
An alarm is provided that indicates if a high temperature condition occurs.
3.3.2.5 Powering
The single-band RU enclosure is equipped with a 4-wire AC power connector that provides a connection
point for the AC power cable distributed from the power distribution junction box. The single-band RU
enclosure is powered by 110/220V AC.
3.3.2.6 User Interface
