Installing the sensor
Caution: Professional installation required. Prior to
installing or using the sensor, consult with a
professional installer trained in RF installation and
knowledgeable in local regulations including building
and wiring codes, safety, channel, power,
indoor/outdoor restrictions, and license requirements
for the intended country. It is the responsibility of the
end user to ensure that installation and use comply
with local safety and radio regulations.
Important: To prevent abuse and intrusion by
unauthorized personnel, it is extremely important to
install sensors such that it is difficult to unplug the
devices from the network or from the power outlet.
Cabling: You must use the appropriate cables, and
where applicable for your region, surge protection.
For compliance with EN55022 Class-B emissions
requirements use shielded Ethernet cables. Cables with
large boots may not insert into the RJ-45 connectors
properly. HP recommends that you do not use such
cables.
Plenum installation: The MSM415 and appropriate
cabling can be installed in a plenum (UL2043 rating).
The sensor should be installed with its top surface
facing the floor (similar orientation as in a ceiling
installation). However, it is left to a qualified installer
to determine how to install/secure the sensor in a
plenum in an appropriate and safe manner.
Plenum-rated cables and attachment hardware must
be used.
Safety: Take note of the following safety information
during installation.
If your network covers an area served by more
than one power distribution system, be sure all
safety grounds are securely interconnected.
Network cables may occasionally be subject to
hazardous transient voltages (caused by lightning
or disturbances in the electrical power grid).
Handle exposed metal components of the network
with caution.
The sensor is powered-on when connected to a
PoE power source.
The sensor and all interconnected equipment must
be installed indoors within the same building
(except for outdoor models/antennas), including
all PoE-powered network connections as described
by Environment A of the IEEE 802.3af standard.
Powering the sensor
The sensor can be powered by:
A 10/100 or 10/100/1000 PoE-enabled switch.
Various PoE-enabled switches are available from
HP.
An HP PoE 1-Port Power Injector (J9407A).
If the sensor will be powered by a user-supplied PoE
power injector, use only a gigabit-compatible power
injector. PoE injectors designed for 10/100 networks
only are not compatible with the sensor.
Mounting the bracket
The sensor can be mounted on a wall or a suspended
ceiling. In either case, the first step is to mount the
bracket, and the second step is to attach the sensor to
the bracket.
Mounting on a wall-mounted electrical box
1.
Disconnect power and take any other needed
security precautions.
2.
Remove the electrical box cover and any contents.
3.
Pull the Ethernet cable down into the box, and
then through the hole in the bracket.
4.
Hold the bracket against the box respecting the
UP indicator, and attach the bracket to the box
using appropriate countersunk screws.
Mounting directly on a wall
1.
Respecting the UP indicator on the bracket, hold
the bracket against the wall at the desired
position. Mark two holes for the screws (wall
anchors) and one hole in the cutout area of the
bracket for the Ethernet cable.
2.
Drill two holes for the wall anchors, typically 4.7
mm (3/16 inch) in diameter.
