XR520H Quick Installation Guide
XR520H Quick Installation Guide
The XR520H Hardened Wireless Access Point provides Xirrus
wireless technology in a hardened case for installation outdoors and
in other harsh environments. This guide describes how to install the
XR520H on a pole or wall and execute the initial power up of the
Access Point. The pole or wall can be a structure that is installed at
ground level or on a roof. The XR520H is not compatible with other
Xirrus mounting options. For additional information, see the Wireless Array User’s Guide.
This document is intended ONLY for XR520H model Access Points. For other XR
models please see the Quick Installation Guide for that model series.
1) You Need the Following Items

Accessory Kit (included in each Wireless Access Point carton) includes:
oMounting bracket and eight attachment screws
oGrounding screw
oWatertight RJ connector assembly

Appropriate tools, bands, screws, and/or anchors required for the desired mounting
location (not provided with the Access Point).

Antenna and low-loss outdoor-rated coaxial cables terminated with N Male to
Reverse Polarity TNC connectors (e.g., Xirrus part number ANT-CAB-195-10-MM).
Note that some antennas include integrated cables as part of the unit, and these do
not need separate cables – an example is shown in the photo in Step 9.

Grounding wire

Workstation with a Web browser to configure the Wireless Access Point.

RJ-45 Ethernet connection(s) to your wired network.

Power—XR520H Access Points are powered via Power over Gigabit Ethernet (PoGE)
using an outdoor-rated Ethernet Cat 5e or Cat 6 cable that also carries data traffic.
Only Xirrus-supplied power injectors, or 802.3af or 802.3at PoE-compliant switches,
may be used to power the XR520H. The XR520H is powered by one injector port
rated at 20W or higher. The Xirrus PoGE Power Injector requires an AC outlet. See
the PoGE Installation Guide for more information.
NOTE: Xirrus PoGE Injectors and switches must be installed and used indoors.

2) Choose a Suitable Location
The XR520H is tested to IP65 water proof and dust proof requirements to protect against
severely wet and dusty environments. For optimal placement, we recommend that a predictive
survey be performed by a qualified Xirrus partner.

Choose a location that is not subjected to submersion.

Direct sunlight may raise the effective ambient temperature many degrees above air
temperature. It is best to choose a location that has some protection from the sun.

The maximum cable length between the XR520H and the RJ-45 Ethernet Network is
100 meters. The PoGE Injector is not a repeater, so its location will not increase this
distance.

The XR520H can operate from a Wireless Distribution System (WDS) link. However,
the unit will need to be configured via the Ethernet connection prior to mounting
and power must still be supplied via the RJ-45 Ethernet connector.

Keep the unit away from electrical devices or appliances that generate RF noise—at
least 3 to 6 feet (1 to 2 meters).
3) Prepare the Mounting Location
Part of the mechanical installation is to ensure that the Access Point is grounded to earth
ground to dissipate any static electric charge that may develop due to wind.

Determine a good electrical earth ground point near the Access Point mounting
location. If an earth ground point is not available, consult an electrician to have one
installed.

Before the Access Point is attached to a wall or pole, secure a grounding wire and
lug to the Access Point with the provided screw in the location indicated by the
arrow, below.

4) Attach the Mounting Plate to the Access Point
The accessory kit includes a mounting plate. Mounting plate dimensions are included in the
Drawings section at the end of this guide. The mounting plate can be used for wall or pole
mounting by reversing the side of the plate exposed. Attach the mounting plate to the Access
Point using the eight provided screws in the locations indicated below (secure in at least 4
places).
For Wall Mounting:
For Wall Mounting, position the bracket with the four slotted flanges pointed towards the
Access Point, as shown in Step 3, above.
For Pole Mounting:
For Pole Mounting, position the bracket with the four slotted flanges pointed away from the
Access Point, as shown below.
5) Mount the Access Point on a Pole or Wall
5a) Pole Mounting
For pole mounting, Xirrus recommends using metal straps (not included with the Access Point).
The metal straps can be obtained from BAND-IT-IDEX, Inc. (www.BAND-IT-IDEX.com). See
their web site for additional contact information. Complete the following steps to mount the
Access Point to a pole.

Install the metal bands through the holes in the
mounting bracket.

Note that the photos below show a different
mounting bracket. The steps for installation are
identical, however.

XR520H Quick Installation Guide

Hand tighten the Band-It strap through the pole
mounting bracket, thread it through the strap buckle
and then bend the strap back.

Using the Band-It tool, place the tool onto the strap.

Rotate the Band-It tool so that it can pull the excess
strap through the buckle and turn the crank until the
strap is very tight.

Once the strap is satisfactorily tight, rotate the Band-
It tool back so that the strap cannot slide back
through the buckle.

Using the built in cutting tool on the Band-
It tool, cut
the excess strap.

XR520H Quick Installation Guide

Your installation should now appear as shown here.

Using a hammer, bend back and flatten the
remaining strap.

Using a hammer, bend and flatten the two tabs on
the buckle to hold the flattened strap end in place.

The completed attachment should have the
mounting bracket firmly seated against the pole.
One band should be enough for most installations
however a second band can be used for additional
mounting security.
5b) Wall Mounting

Place the Access Point in the desired location and
mark the location of the two mounting holes on
the wall, as shown.

Drill and prepare the holes for the desired screw
type. In metal walls the holes may be tapped to
the proper thread or alternatively the Access
Point may be mounted with sheet metal screws.
For concrete walls a plastic anchor and screw are
suggested.
NOTE: Mounting screws for attaching the plate to
the wall are not provided in the kit.

The Access Point should already be secured to the mounting plate (Step 4). Mount
the assembly to the wall, securing it at the two locations indicated.

6) Ground to Earth Ground
WARNING: This equipment must be externally
grounded using a customer-supplied ground wire
before power is applied. Contact the appropriate
electrical inspection authority or an electrician if you
are uncertain that suitable grounding is available.
The mechanical installation must ensure that the AP is
grounded to earth ground to dissipate static electric charge that may develop due to wind. In
Step 3, you secured a grounding wire to the Access Point (see Step 3 if this has not been done).

After Step 3 is complete and the AP is mounted to the wall or pole, attach the
grounding wire from the AP to the electrical earth ground point that you located or
installed in Step 3. The photo shows an earth ground connection where the Access
Point is mounted on a pole at ground level and the grounding wire is attached to a
stake driven into the ground.

Continue the installation by mounting the antenna and attaching the cables as
described in Steps 7, 8, and 9.
7) Install an Antenna
NOTE: See the Warnings and Notices regarding external antennas in the Warning &
Notices section of this guide.
NOTE: Be sure to configure the Access Point’s IAPs to the proper bands (2.4 GHz and
5.0 GHz) in Step 11. Each must match the band of the antenna to which it is connected.

Install your antenna as directed by the manufacturer.

Use low-loss outdoor-rated coaxial cables terminated with N Male to Reverse
Polarity TNC connectors for connection to the AP antenna ports (e.g., Xirrus part
number ANT-CAB-195-10-MM). Note that some antennas include integrated cables
as part of the unit, and these do not need separate cables.
8) Connect the Ethernet Cable with the Waterproof Connector
All XR520H Access Points are powered directly via their Gigabit Ethernet connection.

Power: These Access Points are only powered through the GIG POE port. Only
Xirrus-supplied power injectors, or 802.3af or 802.3at PoE-compliant switches, may
be used to power the XR520H.

Data: Data is supplied to the Gigabit port via the same cable that powers the Access
Point.
NOTE: It is VERY IMPORTANT to assemble the waterproof connector properly,
following the directions below. Failure to do so may expose the AP to the elements, and
may result in an intermittent connection causing the AP to connect at very low speeds!

XR520H Quick Installation Guide

The Ethernet cable must be terminated with a simple RJ45 plug with the tab exposed,
as shown on the left below. Do not use a plug with a tab protector boot, as shown on
the right. This will not seat properly in the waterproof connector, and the assembly
will not be watertight.

The components of the connector are shown in the photo below in the order that
they are placed onto the Ethernet cable, and also shown in more detail as a color-
coded drawing. You will perform a few assembly steps below before sliding the
parts onto the cable.

Seat the O-ring (shown in red) on the connector body (gray) at its RJ45 jack side.

Note the slots in the collar of the connector body and the matching tabs inside the
connector ring. Insert the connector body into the connector ring so that they mate.

Slide the sealing nut (shown in green) and the connector body assembly over the
Ethernet cable as shown.


Attach the split washer and split rubber grommet over the cable.

Seat the washer in the sealing nut and slide the grommet into the connector body.

Snug all of the components together as shown, but leave the RJ45 connector
protruding. Tighten the sealing nut lightly, making sure that the RJ45 connector is
rotated so that it will seat easily in the connector body later.

Plug the RJ45 connector into the port on the bottom of the XR-520H, making sure that
its tab clicks in place for a secure connection.

Seat the RJ45 connector correctly in the connector body.

Note the slotted track in the connector ring on the bottom of the AP and the
matching tabs inside the connector ring in the waterproof connector assembly,
below. Screw the assembly onto the AP’s connector ring so that they mate securely.
