Xirrus I-Beam Mounting Kit For XN4, XS4 And XS-3500 ... - Moonblink

I-Beam Mounting Kit
XE-2100/2120
Installation Guide
The Wi-Fi Array I-Beam Mounting Kit is intended for indoor
applications that require suspending a Wi-Fi Array from an exposed
I-beam. There are two versions of this kit:
w
w
XE-2100—for four-port Arrays: XS4 and XS-3500
XE-2120—for eight- and sixteen-port Arrays: XS8/16 and
XS-3700/3900
The key features of the I-Beam Mounting Kit include:
w Secure mounting—security chain provides an extra level of
protection.
w Simple to install—only a few common tools are required and
no holes must be drilled.
The photo at the right shows a complete installation. In this case, a
customer supplied Lexan shield has also been installed. This is not
part of a typical installation, and is not needed unless the Array is
being used in an environment with a risk of physical impact.

I-Beam Mounting Kit Installation Guide
Prepare for Mounting the Array
1. Determine the mounting location. Carefully review any local building codes, and read the
planning information, installation prerequisites, and installation instructions in “Installing the
Wi-Fi Array” in the Xirrus Wi-Fi Array User’s Guide, Part # 800-0006-001.
Determine the desired mounting orientation of the Array. The orientation is described in terms
of where the Array’s abg2 radio is pointed. Since abg2 is typically used as a monitor, the Array is
commonly oriented to point abg2 towards the area of least required coverage (for example,
towards an outside wall). Changing the orientation of the Array is discussed in Step 4 on page 5.
Check for obstructions at the mounting location. In general, place the mount away from
fluorescent light fixtures, metal pipes, etc., if the option is available.
2. Run and terminate the power and data communication cables that will be connected to the
Wi-Fi Array. If external antennas will be used with the Array, they should be terminated with
RP-TNC connectors. See “Installing the Wi-Fi Array” in the Xirrus Wi-Fi Array User’s Guide to
determine your cabling requirements. .
It is recommended to leave a service loop of cable length (at least 10 extra feet) at the location of
the installation for servicing the Array and for potential adjustment of the mounting location.
Power: There are different power options for the Array, depending on the type of power used
by the Array (AC or DC), and whether you will be using Xirrus Power over Gigabit Ethernet
(PoGE). If you purchased a Xirrus power system, please see the guide provided with it.
Data: Run the data cables to the Array, based on which ports you will be using (Gigabit 1,
Gigabit 2, Fast Ethernet, Serial).
Install the I-beam Mounting Bracket
2. Secure bolts against I-beam
1. Mount the bracket to the underside of the I-beam,
adjusting the positions of the I-beam clamps to fit
the beam snugly. Make sure that the I-beam
clamps are located so that both clamps adequately
clamp on to the I-Beam itself. It may be necessary
to move the I-Beam clamps on the bracket either in
or out. If this is necessary, use a 9/16" socket
wrench to loosen the 3/8" bolt a couple of turns,
slide the clamp into the desired location, and
retighten the clamp to the UniStrut bracket.
1. Adjust I-beam clamps
2. Next, place the I-Beam clamp on to the I-Beam. Using a crescent wrench (or an appropriate
open ended wrench), tighten the square head bolts on top of the clamps to hold the bracket in
place. There is no need to overtighten this clamp, as the square head bolts simply hold the
clamp and bracket assembly in place.

Attach Array Mounting Plate to Bottom Plate
The Array mounting plate (supplied with the Array) must be fastened to the I-beam mount’s bottom
plate. There are two types of bottom plate as shown below, but the procedure is the same for both.

Bottom Plate: for XS4 and XS-3500
XE-2120
8/16-Port Array Mounting Plate installed on
Bottom Plate: for XS8/16 and XS-3700/3900
1. Line up the Array mounting plate with the mounting holes on the bottom plate of the I-beam
mount. (Orientation of the Array mounting plate with respect to the Array’s abg2 radio is not a
concern—it may be changed by rotating the bottom plate with respect to the down rod.)
2. Using the four supplied 1/4-20 x 3/4” bolts, secure the mounting plate to the bottom plate (4
places, as shown). Tighten to 10-12 lbf.ft (1.38-1.66 kgf.m). Do NOT over-tighten the bolts or the
plate may be damaged.
3. Attach the bottom plate to the threaded end
of the down rod, screwing it on firmly.
Make sure that the union ring is screwed
down tightly.

4. The down rod is furnished with the collar at
the top assembled. If you disassemble it,
reassemble it as follows:
Important! The pin goes through the two
larger holes at the top of the rod, and the
collar slides up to seat the pin in slots
inside the collar. Tighten the set screw,
ensuring that is seated in the set screw hole,
as shown on the right.

Note to the installer: It is critical that this component be assembled correctly, as the full weight of the
assembly is supported by the pin, not the set screw.

Suspend the Down Rod
1. Hang the down rod from the I-beam by seating the
down rod’s collar in the black cup under the I-beam
bracket.
2. Secure the rod to the beam with the security chain.
Fasten the clamp at the end of the chain to the
I-beam as shown on the right. Using a crescent
wrench (or an appropriate open ended wrench),
tighten the square head bolts on top of the clamp to
hold the clamp in place.
3. Verify that the clamp attaching the chain to the rod is
tightly fastened.
4. If you need to adjust the orientation of the mounting plate, you may slightly loosen the union
ring above the bottom plate (see the Bottom Plate Assembly on page 2), and rotate the plate.
Secure the union ring tightly when you are done.
Connect Data and Power Cables
1. Feed the cables through the mounting plate for 8- and 16-port Array models, then connect the
cables to the Array.
2. When the cables are connected, turn on the power switch—before attaching the unit to the
mounting plate (next step). Verify that the Ethernet link LED lights and the LED boot sequence
begins. The radio LEDs on the front of the unit will illuminate in rotation, indicating that the
Array software is loading and the unit is functioning correctly.
Attach the Array to the Mounting Plate
1. Gently align the Array with the key post on
the mounting plate, then turn the Array to the
right to lock the unit into place at the 4 lugs—
similar to a smoke detector.
