Important information to read before installing
Warning: Professional installation is required. For indoor installation
only. Before installing or using the AP, 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. The end
user is responsible for ensuring that installation and use comply with local
safety and radio regulations.
Before installing the AP, read all of the safety instructions in the Compliance
and Safety Guide included with the AP.
Cabling: You must use Cat 5e (or a higher category) cables, and where
applicable, surge protection.
Plenum installation: The AP can be installed in a plenum. The AP is suitable
for use in environmental air space in accordance with Section 300-22(C) of the
National Electrical Code, and Sections 2-128, 12-010(3) and 12-100 of the
Canadian Electrical Code, Part 1, CSA C22.1. It should be installed in a similar
orientation as in a ceiling installation. However, a qualified installer can
determine how to install/secure the AP in a plenum in an appropriate and safe
manner. Plenum-rated cables and attachment hardware must be used.
Safety: Consider the following safety information during installation:
• If your network covers an area served by more than one power distribution
system, ensure that all safety grounds are securely interconnected.
• Network cables can 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 AP is powered on when connected to a PoE power source or a local
power supply.
• The AP and all interconnected equipment must be installed indoors within
the same building (except for outdoor antennas), including all
PoE-powered network connections, as described by Environment A of the
IEEE 802.3af standard.
• Install the AP in a dry area, away from liquids.
• Ensure that the installation site is flat and anti-slip measures are in place.
• Keep the AP clean and dust-free.
Powering the AP
The AP can be powered by:
• A 10/100 or 10/100/1000 PoE-enabled switch. Various PoE-enabled
switches are available from HP.
• A PoE power injector, such as J9407B.
• An HP 48 volt power adapter, JD055B.
The AP requires 802.3af-compliant PoE. For best performance, HP
recommends that you use a gigabit connection.
Caution: If the AP will be powered by a user-supplied PoE power injector,
use only a gigabit-compatible power injector. Although 10/100 PoE-enabled
switches are compatible, PoE injectors designed for 10/100 networks only are
not compatible with the AP.

HP 425 Wireless Dual Radio 802.11n Access Point Quickstart 3 Selecting the installation site
Selecting the installation site
Consider the following:
• To meet regulatory RF exposure requirements, install the AP and any
external antennas at least 40 cm (15.75 inches) from any person.
• Install APs away from RF-emitting electronic devices, such as microwave
ovens.
• Do not install APs in a location where water seepage or condensation
occurs.
• Do not place the AP on a metal surface.
• Install the AP where there are no obstacles and wireless clients can receive
a strong signal from the AP.
Installation
The AP can be mounted on a non-metallic table or shelf, a wall, or a ceiling.
When mounting on a wall or ceiling, mount the AP bracket first, and then
attach the AP to the bracket.

Preparing for installation
HP recommends that you connect power and verify the Ethernet cable and
LEDs before you install the AP in a hard-to-reach location.
Record the MAC address and AP serial number for future reference.
If part of the power line is routed outdoors, connect the AP power cord to a
user-supplied power strip with lightning protection.
Placing the AP on a table or shelf
1. Attach the rubber feet to the back of the AP (callout 7 on page 1), and
place the AP back-side down on the table or shelf.
2. Connect an Ethernet cable to the AP.
3. Connect the other end of the Ethernet cable to a PoE-capable device, such
as an Ethernet switch.
Mounting on a wall
1. Hold the mounting bracket with the narrow end facing up, against the wall
where you want to install the AP. Mark the location of the three screw
holes.
2. Drill three holes for the wall anchors, typically 5 mm (3/16 inch) in
diameter.
3. Insert the anchors and tap them flush with the wall surface.
4. Use the mounting screws to attach the mounting bracket to the wall.
Proceed to Attach the AP on page 5.
Mounting on a suspended ceiling

AP so that it does not fall.
Controllers
To become operational, the AP must establish a management tunnel with an
HP 10500/7500 WLAN Module, HP 830, HP WX5002/WX5004, or HP
MSM720/MSM760/MSM765 zl Controller. The controller manages the AP and
provides all configuration settings.
Note: Both controller families cannot coexist on the same network. HP
10500/7500 WLAN Module, HP 830, and HP WX5002/WX5004
Controllers are not compatible with HP MSM7xx Controllers.
When power is applied, the AP establishes a connection to the controller
automatically if the AP and the controller are on the same subnet and have IP
connectivity.
