Trapeze Networks
MX Recommendation
Trapeze Networks recommends that you install and configure the MX before installing an MP. If the
MX is already installed and configured for the MP, you can immediately verify the cable connection(s)
when you plug the cable(s) into the MP.
Wall Installation Recommendations
If you plan to install an MP on a partial wall or other vertical surface, orient the top of the MP (the
side with the LEDs) toward the intended coverage area. The radio antennas transmit through the top
of the MP but not through the bottom, where the bracket is located.
This recommendation does not apply if you plan to use external antennas. You can orient the
antennas independently of the MP. Orient an external antenna to face the intended coverage area.
MP Radio Safety Advisories
When you enable the MP radio(s) as part of MX configuration, the radios can 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 MPs meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1-1991.
Proper installation of the MP according to the instructions in this manual will result in user exposure
that is below the FCC recommended limits.
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one of the following measures:
❑Reorient or relocate the receiving antenna.
❑Increase the separation between the equipment and receiver.
❑Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
❑Consult the dealer or an experienced radio/TV technician for help.
Warning!
An Indoor MP is designed to receive power only from an 802.3af-compliant source, a
Trapeze Networks Mobility Exchange (MX), or a Trapeze-approved power injector.
Connecting an MP to a Power over Ethernet (PoE) device not approved by Trapeze
Networks can damage the equipment.

FCC Caution for the MP-522E
To comply with FCC part 15 rules in the United States, the system must be
professionally installed to ensure compliance with the Part 15 certification. It is the
responsibility of the operator and professional installer to ensure that only certified
systems are deployed in the United States. The use of the system in any other
combination (such as co-located antennas transmitting the same information) is
expressly forbidden.
The device could automatically discontinue transmission in case of absence of
information to transmit, or operational failure. Note that this is not intended to
prohibit transmission of control or signaling information or the use of repetitive codes
where required by the technology.
The device for the band 5150-5250 MHz is only for indoor usage to reduce potential for
harmful interference to co-channel mobile satellite systems.
The maximum antenna gain permitted (for devices in the bands 5250-5350 MHz and
5470-5725 MHz) to comply with the e.i.r.p. limit.
The maximum antenna gain permitted (for devices in the band 5725-5825 MHz) to
comply with the e.i.r.p. limits specified for point-to-point and non point-to-point
operation as appropriate, as stated in section A9.2(3).
High-power radars are allocated as primary users (meaning they have priority) of the
bands 5250-5350 MHz and 5650-5850 MHz and these radars could cause interference
and/or damage to LE-LAN devices
