o The position of the Antenna Unit should provide sufficient air circulation
For mounting in a 19” equipment rack, chose the Antenna Unit position following these
guidelines:
o Locate free space in the rack of 3U height
o Use a location which allows for minimum coaxial cable length to connect the
antenna
Follow the following steps to mount the AU in a 19” equipment rack using the rack
mounting kit (optional)
o Attach the 277X AU to the shelf using the 4 provided screws.
o Place the shelf into the rack and secure with the 4 provided screws
3.4.4.3 Connecting the Antenna to the AU
Connect the antenna to the AU, using low loss coaxial cables. If the antenna cable is
terminated with a connector other than N-type (male) on the AU end, use an
appropriate connector adaptor.
When connecting an N-type connector, firmly hand-tightening is adequate.

3.4.4.4 Connecting the Optical Fiber
o When using MMF, connect the 277X AU to the fiber-infrastructure using the
special Zinwave patch-cord. Connecting to the fiber-infrastructure without the
special patch-cord will lead to a poor quality optical link and reduced maximum
transmission distance.
o Connect the patch-cord end with the SMF (yellow) and MMF (orange or grey)
cords to the AU. Connect the patch-cord end with the two MMF (both cables
either orange or grey) cords to the fiber infrastructure.
o The SC connectors are keyed with a slot and will thus only fit in one (i.e. the
correct) direction.
o Insert the SC duplex connector into the optical I/O port on the AU and press it
firmly into place, making sure that both sides of the connector are securely
latched (indicated by a “clicking” sound)
