2-6 Aviat Networks
Chapter2. Health and Safety
• Eclipse with IRU600, 5.8 GHz, has been tested and certified for use with a parabolic
antenna with a maximum gain of 46.8 dBi. Higher gain antennas must not be used.
• The maximum transmit output power on the IRU 600 has been limited to a
maximum of 1W (30dBm) at the antenna port, to comply with the conducted power
limit in FCC CFR 47, Part 15.247.
Routine Inspection and Maintenance
This section overviews required and recommended inspection and maintenance
practices to ensure health and safety of installed equipment is maintained to highest
levels. For more information, refer to the Aviat publication: Best Practices.
Routine Inspections
All sites must be inspected annually, or more frequently if subject to abnormal
operating conditions such as particularly exposed sites, or sites subject to salt-spray or
heavy snow/ice loading over winter months.
The inspection should cover the physical installation including the antenna,
waveguide, equipment grounding, tower and building grounds, weatherproofing, and
general site integrity.
Where a Fan Air Filter is installed in an INU (for NEBS compliance) it must be
inspected annually, or more frequently if the INU is installed in an environment that is
nor controlled for dust exclusion.
Selected ground wires should be resistance checked and then compared with previous
checks to ensure there has been no significant change.
The operational performance of the radio and associated equipment should be checked
against their as-built figures.
Trend Analysis
Use available current and historical Eclipse alarm and performance data to determine
any trend that may lead to a failure - if allowed to continue.
Check for the following trends:
• Reducing receive signal levels
• Gradually increasing bit errors or an increasing errored seconds count
• Changes in transmit power
• Increasing occurrence of other weather related changes in performance
• Increasing occurrence of a particular hardware failure
Time spent in conducting such analysis is time well spent. Catching a problem before
it brings down the network is good network management.
