Surge protection and grounding

WARNING
If you plan on connecting an outdoor antenna to the MSM320, make sure that proper
lightning surge protection and grounding precautions are taken according to local electrical
code. Failure to do so may result in personal injury, fire, equipment damage, or a voided
warranty. The HP hardware warranty provides no protection against damage caused by static
discharge or a lightning strike.

Cabling

You must use the appropriate cables, and where applicable, surge protection, for your given
region. For compliance with EN55022 Class-B emissions requirements, use shielded Ethernet
cables.

Plenum installation

The MSM320 can be installed in a plenum (UL2043 rating). It should be installed in a similar
orientation as in a ceiling installation. However, it is left to a qualified installer to determine
how to install/secure the MSM320 in a plenum in an appropriate and safe manner. Plenum-
rated cables and attachment hardware must be used.

Country of use

In some regions, you are prompted to select the country of use during setup. Once the
country has been set, the MSM320 will automatically limit the available wireless channels,
ensuring compliant operation in the selected country. Entering the incorrect country may
result in illegal operation and may cause harmful interference to other systems.

External Antennas

Caution
When using an external antenna, depending on the country of use, the antenna selected, and
your radio settings, it may be mandatory to reduce the radio transmission power level to
maintain regulatory compliance. For specific power limits for your country, consult the
Antenna Power-Level Setting Guide (for MSM Products) available from:
www.hp.com/networking/support
To set the radio power transmission level, for controlled access points see Transmit power
control in the MSM7xx Controllers Management and Configuration Guide. For autonomous
access points, see Transmit power control in the MSM3xx / MSM4xx Access Points
Management and Configuration Guide.

Power supply

The MSM320 is intended to have its power supplied by a Listed Information Technology
Equipment AC Adaptor, Sparkle Co. Inc., Models FSP015-1AD201A or FSP015-DYAA1xx,
rated output 5 Vdc, 3A (marked Class 2 or LPS) available as HP part number J9405A. As an
alternative, the MSM320 may be connected to an external PoE source.
