Installing and Connecting an MP-622
Installation Requirements and Recommendations
MP-622 Installation Guide
3 – 2
Rain — The MP-622 is weatherproofed against rain. Also, prolonged heavy rain has no
significant effect on the radio signal. However, it is recommended to apply weatherproof sealing
tape around the Ethernet port and antenna connectors for extra protection. If moisture enters
a connector, it may cause a degradation in performance.
Snow and Ice — Falling snow, like rain, has no significant effect on the radio signal. However,
a build up of snow or ice on antennas may cause a degradation in performance. In this case, the
snow or ice has to be cleared from the antennas to restore proper operation of the unit.
Ethernet Cabling
When you have determined a suitable location for the MP-622, you must plan a cable route from
the MP-622 outdoors to the power injector module indoors. Consider these points:
The Ethernet cable length should never be longer than 328 ft (100 m).
Determine a building entry point for the cable.
Determine if conduits, bracing, or other structures are required for safety or protection of the
cable.
For lightning protection at the power injector end of the cable, consider using a lightning
arrestor immediately before the cable enters the building.
Grounding
It is important that the MP-622 unit, cables, lightning arrestors, and any supporting structures
are properly grounded. The MP-622 unit includes a grounding screw for attaching a ground wire.
Be sure that grounding is available and that it meets local and national electrical codes.
MP Radio Safety Advisories
When you enable the MP radio(s) as part of MX configuration, the radios are able to receive and
transmit radio frequency energy as soon as you connect the MP to the MX, either directly or
through the network.
Radio Frequency Exposure
Federal Communications Commission (FCC) Docket 96-8 for Spread Spectrum Transmitters
specifies a safety standard for human exposure to radio frequency electromagnetic energy emitted
by FCC-certified equipment. When used with the proper antennas (shipped in the product),
Trapeze Networks MP access point products meet the uncontrolled environmental limits found in
OET-65 and ANSI C95.1-1991. Proper installation of the MP access point according to the
instructions in this manual will result in user exposure that is below the FCC recommended
limits.

See the Outdoor Power Supply Installation Guide for details on installing the power
supply for the MP-622.
