Preparing for configuration and alignment
This section describes the checks to be performed before proceeding with unit
configuration and antenna alignment.
Safety precautions during configuration and alignment
All national and local safety standards must be followed while configuring the units
and aligning the antennas.
WARNING
Ensure that personnel are not exposed to unsafe levels of RF energy.
The units start to radiate as soon as they are powered up. Respect the
safety standards defined in Compliance with safety standards on
page 4-22, in particular the minimum se
paration distances. Observe
the following guidelines:
o Never work in front of the antenna when the ODU is powered.
o Always power down the PoE power supply (or PIDU) before connecting or
disconnecting the drop cable from either the power supply, ODU or LPU.
Regulatory compliance during configuration and alignment
All applicable radio regulations must be followed while configuring the units and
aligning the antennas. For more information, refer to Compliance with radio
reg
ulations on page 4-27.
Selecting configuration options
Use the installation report to determine which configuration options are required.
