Notices, Warnings, & Compliance Statements
Notices
Read all user documentation before powering this device. Please verify the integrity of the
system ground prior to installing Xirrus equipment. Additionally, verify that the ambient
operating temperature does not exceed 65°C.
Software used by the modular Arrays (APs) is covered by the Xirrus Software License and
Product Warranty Agreement.
Non-Modification Statement: Unauthorized changes or modifications to the device are not
permitted. Use only Xirrus-approved external antennas supplied or recommended by the
manufacturer. Modifications to the device will void the warranty and may violate FCC
regulations.
UL Statement: Use only with listed ITE product.
Operating Frequency: The operating frequency in a wireless LAN is determined by the
Array. It is important that the Array is correctly configured to meet the local regulations. If
you have questions regarding the compliance of Xirrus products, please contact us at:
Xirrus, Inc., 2101 Corporate Center Drive, Thousand Oaks, CA 91320, USA. Tel:

The 2-GHz b/g/n radio operates in 2.4 GHz ISM band. It supports channels 1-11 in US, 1-13
in Europe, and 1-13 in Japan. It has two transmitters with a maximum total output power of
25dBm for 802.11b/g/n operation. Output power is configurable to 5 levels. It has three
receivers that enables maximum-ratio combining (MRC).
The 5-GHz a/n radio operates in the UNII-2 band (5.25 - 5.35 GHz), UNII-2 Extended/ETSI
band (5.47 - 5.725 GHz), and the upper ISM band (5.725 - 5.850 GHz). It has two transmitters
with a maximum total output power of 26 dBm for UNII-2 and Extended/ETSI bands for the
A-domain. The total maximum output power for the upper ISM band is 28 dBm for A-
domain. Power settings will change depending on the regulatory domain
High power radars are allocated as primary users (meaning they have priority) in the
5250MHz to 5350MHz and 5650MHz to 5850MHz bands. These radars could cause
interference and/or damage Wireless LAN devices.
Calculating the Maximum Output Power: The regulatory limits for maximum output power
are specified in EIRP (equivalent isotropic radiated power). The EIRP level of a device can
be calculated by adding the gain of the antenna used (specified in dBi) to the output power
available at the connector (specified in dBm).
