Preparing for installation
Before starting the installation, perform the checks described in this section.
Safety precautions during installation
When developing a site, installing equipment, or performing maintenance, ensure that all
national and local safety standards are followed by all personnel.
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 Radiation hazard assessment on page 4-86, in particular the
minimum separation distances.
Observe the following guidelines:
• Never work in front of the antenna when the CMU is powered.
• Always power down the CMU before connecting or disconnecting the drop cable from
the CMU, ODU or LPU.
Grounding and lightning protection requirements
Ensure that the installation meets the requirements defined in Grounding and lightning
protection on page 2-7.
Selecting installation options
Use the installation report to determine which installation options are required. Refer to
Link planning on page 2-2.
When installing a 1+1 Hot Standby link, refer to 1+1 Hot Standby link protection on page
1-64 for an overview of alternative hardware configurations.
