Remarks
8.1
Maximum EIRP
The transmit EIRP is the sum of the conductive transmit power, IEEE Std 802.11n
multilple stream effect, and the antenna gain. By default, Meru 433 SERIES AP
EIRP is set lower than the regulatory limit with the default antenna.
8.2
Dual Concurrent Same Band Operation
With grant of additional regulatory approval and FCC Permit-but-Ask, users may
configure two radios in 433 SERIES AP on the same band (i.e., two or three
radios are on the 5.x CHz but in the different or same channels).
However, user shall expect performance deterioration due to RF collision and
collocation interference. It is important that users adopt external antennas, with
extended coaxial pigtail cables, with 433 SERIES APe in such use case. User
shall place antennas far apart to reduce interference.
Meanwhile, user shall also reduce 433 SERIES APe transmit power, for each
radio, by at-least 3 dBm from its default setting.
8.3
Manufacturing Information
The 433 SERIES AP models are built in China. Contact with Meru Networks for
manufacturing related information.
8.4
Distributed Antenna Systems (DAS)
Meru Networks does not certify or endorse any specific Distributed Antenna
System (DAS) vendors. Meru Networks will provide support to Meru Wi-Fi
customers that use distributed antennas within the terms and conditions of the
MeruAssure Terms of Service and in accor- dance with the customer's support
agreement. Meru Customer Support will support Meru software and hardware,
and will work jointly with DAS vendors to identify and troubleshoot issues, but any
support related to RF issues, including RF coverage, shall be the responsibility of
the DAS vendor.
Meru Networks recommends that customers use only a DAS that has been tested
to work with Meru hardware and software. Meru does not provide any site surveys,
design or implementa- tion of Wi-Fi over DAS. Meru recommends that customers
obtain such services from a trained and qualified systems integrator or from their
DAS vendor.
8.5
Air Handling Space Requirements
When installing APs in an air-handling space, as described in Article 300.22(C) of
the National Electric Code® (2008 edition, pages 70-135 and 70-136), the unit
should only be powered by the Ethernet port (PoE), not by the AC-powered power
supply.
Note
Only AP433e can be applied in air-handling space.
When the product is installed in air-handling spaces, the cables employed should
be suitable under NEC Articles 300.22 and 725 and marked accordingly, for use in
plenums and air-handling spaces with regard to smoke propagation, such as CL2-
P, CL3-P, MPP or CMP.
The products should be installed in accordance with all applicable, local
regulations and practices. Compliance applies only when the plastic facade is
removed from the AP.
