Preparing for installation
IMPORTANT:
For regulatory identification purposes, the HP 425 is assigned a regulatory model number (RMN)
BJNGA-FB0002. This regulatory number should not be confused with the marketing name HP 425, or
product code JG653A, JG654A, JG655A, JG656A, JG687A, and JG688A.
Safety recommendations
W
ARNING!
•This product is designed for specific application and needs to be installed by someone with RF and
related rule knowledge. The general user shall not attempt to install or change the setting.
•Before installation and operation, read all of the safety instructions in
Compliance and Safety Guide
supplied with your AP.
General safety recommendations
To avoid possible bodily injury or equipment damage, read the following safety recommendations
before you install an HP 425. The recommendations do not cover every possible hazardous condition.
•Make sure the ground is dry and flat and anti-slip measures are in place.
•Keep the chassis clean and dust-free.
•Do not place the AP in a moist area and avoid liquid surrounding the AP.
•Keep the chassis and installation tools away from walkways.
European Union Commission Regulation 1275/2008
The power data for affected products—including the power consumption of the product in networked
standby if all wired network ports are connected and all wireless network ports are activated—is
provided in section P14, “Additional information,” of the product IT ECO Declaration available
at http://www.hp.com/hpinfo/globalcitizenship/environment/productdata/iteconetworking.html.
Checking the installation site
W
ARNING!
Please carefully select the installation position and make sure the final output power does not exceed the
limit set forth in relevant rules. The violation of the rule could lead to serious federal penalty.

2
Determine the installation position by observing the following principles:
•To meet regulatory RF exposure requirements, install the device at a location where the radiating
antenna can be kept 40 cm (15.75 in) from any person.
•Leave as few obstacles (such as wall) as possible between APs and clients.
•Install APs away from electronic devices (such as microwave ovens) that might generate radio
frequency (RF) noise.
•Do not install APs in a place where water seeping, water soaking, and condensing occur. Prevent
water or moisture from entering the APs.
•Do not place the device on any metal surface. Place it where there are no obstacles and good
signal strength is available.
Accessories provided with the AP
W
ARNING!
Only use the antennas which have been approved by the applicant. Unapproved antenna(s) may produce
unwanted spurious or excessive RF transmitting power, which is prohibited and could be in violation of
FCC/IC limits.

Installation preparation checklist
Before you install an AP, verify the following items:
•Connect the power cord and connect the AP to the network. Examine the LED status to make sure
the AP can operate correctly. For more information about AP LEDs, see "Appendix B LEDs."
•Verify that cabling has been completed.
•The device supports 802.3af-compliant PoE. To achieve the best performance, HP recommends that
you use a GE connection to the power device.
•Record the MAC address and serial number of the AP (marked on the rear of the AP) for future use.
•If part of the power line is routed outdoors, use a power strip with lightning protection (user supplied)
to connect the power cord of the AP to the power line.

To mount the AP to a ceiling T-rail:
1. Loosen the two M3 × 8 screws on each clip holder. Do not remove the screws.
2. Adjust the T-rail clips to make the T-rail holder wider than the T-rail. See callout 1 in Figure 11. Then
lock the T-rail with the T-rail holder according to the arrow indicated in callout 2 in Figure 11.
Figure 11 Attaching the T-rail holder to the T-rail
3. Tighten the four M3 × 8 screws on the two clip holders.
4. Verify that the T-rail holder is attached to the T-rail.
5. Hook the mounting clip (see callout 3 in Figure 12) of the wall-mounting bracket to the mounting
hook (see callout 2 in Figure 12) of the T-rail holder.
6. Insert the two M4 × 5 screws (see callout 1 in Figure 12) through the two 5 mm (0.20 in) diameter
holes on the wall-mounting bracket according to the dashed line shown in Figure 12. Attach the
screws to the T-rail holder.
7. Verify that the wall-mounting bracket is attached to the T-rail.
8. Connect the AP to the network by using an Ethernet cable.

Mounting the AP on a ceiling
CAUTION:
•Verify that the AP is secured to the mounting bracket to avoid falloff.
•Do not use this method to mount the AP to a location made of low-intensity materials such as a plaster
ceiling. If this installation method is required in such an environment, put a high-intensity plate beneath
the ceiling to secure the installation.
•The ceiling tiles must be less than 18 mm (0.71 in) thick, and the ceiling must be able to bear a wei

To install the AP on a ceiling:
1. Drill three 5.0 mm (0.20 in) diameter holes in the ceiling where you want to mount the AP. The
distance between the three holes must be the same as the distance between the three bolt holes on
the mounting bracket.
2. Insert the hex-head bolts into the bolt holes on the mounting bracket and the holes in the ceiling.
From above the ceiling, fasten the hex nuts to the hex-head bolts to fix the mounting bracket to the
ceiling.
3. Connect the AP to the network by using an Ethernet cable.
4. Install the AP to the wall-mounting bracket. For more information, see "Mounting the AP on a wall."

Connecting the power supply
The device can be powered by using a local or PoE power supply. You can select either method as
needed. Make sure the power supply for either method is well grounded before you power on the AP.
Before you connect the local or PoE power supply, verify that the power supply is steady. You can use a
local power source, an uninterruptible power supply (UPS), or a user-supplied power generator to supply
power to the AP.

After powering on the AP, examine the AP status LED. For more information about AP LEDs, see
“Appendix B LEDs."
Connecting the AP to a local power supply
The AP is not shipped with a power adapter or power cable.
The device supports both listed AC and DC power adapters marked “LPS” or limited power source. You
can connect the power port of the AP to the power source through a power adapter to supply power to
the AP as shown in Figure 15.

Connecting the AP to a PoE power supply
CAUTION:
Identify the marks for the network port and console port to avoid connection mistakes.
When you apply 802.3af PoE power supply, connect one end of the network cable to the network port
on the AP, and the other end to an Ethernet port on a PoE-capable device (for example, a PoE-capable
Ethernet switch). If the uplink device of the AP is a PoE switch, use an Ethernet cable to directly connect
the Ethernet port of the AP to the PoE device as shown in Figure 16.(indoor used)

Connecting the AP to the network
APs can access the Internet or metropolitan area network (MAN) through the Ethernet uplink interface. To
implement Internet or MAN access, connect the Ethernet port of the AP to an Ethernet port of an Ethernet
switch.
When the AP operates as a fit AP, all of its settings are configured on the AC. You can use the display
wlan ap all command to examine the AP status on the AC. When the AP status is R/M, the AP has been
successfully connected to the AC.
