Mounting
The QH450 hot standby full duplex radio is housed as a 3RU 19” rack mounted set, encompassing 2 x 1RU QB full duplex
radios and 1 x 1RU QH Hot Standby Controller. The Controller and full duplex radios are each supplied with x2 1RU mounting
brackets, which should be fitted to each sides of each unit before it can be installed into a 19” rack. The mounting brackets
can be fitted to the side of each unit in 3 different locations to provide different mounting capabilities: Front Mount, Proud
Mount or Center Mount. Refer to the QB450 Mounting guide for a graphical representation of the different mounting
positions.
The unit should be mounted in a clean and dry location, protected from water, excessive dust, corrosive fumes, extremes
of temperature and direct sunlight. Allow sufficient passive or active ventilation to allow the full duplex radio fans to pass air
through the internal heat sink efficiently.
All RF, power and digital I/O connections are made at the rear of the unit. All User interfaces are located at the front of the
unit, this includes: Ethernet interface, Serial COM port interfaces and Auxiliary interfaces.
