InCell ERAU Installation
ERAUs are typically mounted on walls or ceilings throughout the building according to a design
drawing. ERAUs may also be mounted in ceiling rafters, beams or on to poles. Upon
application of system power, indicators on the ERAU give the installer a visual indication of
ERAU power and link status.
Allow 45 minutes for installing the ERAU and connecting the antenna, fiber and power cables.
Upon application of system power, indicators on the ERAU front panel will give the installer a
visual indication of power and the downlink link status.
Connect the antenna jumper cable to the ERAU Type N connector and ensure that the connector
is tight, but do not over-tighten and damage the ERAU connector.
If a composite fiber optic/power cable is being used between the CDU and the ERAU, connect
the plastic 2-pin power connector of the cable to the power connector on the ERAU. The
connectors are keyed to ensure that there are no power polarity problems. If local DC power is
used for the ERAU, connect the local power supply to the AC source and the plug the DC power
supply into the auxiliary power connector on the ERAU. Andrew can provide an optional DC
wall mount power supply with 6-foot cord for local powering of the ERAU.
To ensure trouble free connections, all fiber optic connectors on the ERAU and their mating
cable connectors should be thoroughly cleaned using high purity (99%) alcohol and dry
compressed air.
