Warning:
Do not operate access point near unshielded blasting caps or in an otherwise explosive
environment unless the device has been modified for such use by qualified personnel.
Warning:
Do not touch or move the access point when the antennas are transmitting or receiving.
Warning:
Before using a wireless device in a hazardous location, consult the local codes, national codes,
and safety directors of the location for usage constraints.
Cable requirements
The Ethernet ports on the access point cannot accept a CAT-5 cable that has an uneven sheath as
shown below. The RJ-45 connector on the cable will not seat properly in the receptacle on the
access point. Use a CAT-5 cable with an even sheath instead.
Mounting the WLAN AP 8120 with External Antenna on a wall
About this task
The WLAN AP 8120 with External Antenna installs similarly to the WLAN AP 8120. In addition to
installing the access point itself, with the WLAN AP 8120 with External Antenna you must also
mount the adjoining antennas. You can mount the WLAN AP 8120 with External Antenna on the
wall using wall anchors.
Plan your installation to allow for the installation of both the access point and the antennas. Ensure
you have the correct length of cable to connect the access point to the antennas. Each antenna
comes with three 3–ft pre-installed permanent cables. If your installation distance is greater than the
length of the original cables, you can attach additional 10–ft extension cables.
Note:
Assembling the external antenna to the WLAN AP 8120 with External Antenna is completed
through Reverse Polarity SMA (RP-SMA) connectors. The installer should properly torque the
connector using a 5/16 inch torque wrench that is set to 3-5 in·lbf (0.3 to 0.6 N·m) for brass, and
7-10 in·lbf (0.8–1.1 N·m) for stainless steel connectors. Flats are also provided on the cable
side of the connector assembly so that you use a second wrench to prevent it rotating and
damaging the joint to the cable. Avaya also recommends that you clean out loose debris from
the internal surfaces before connecting.

Warning:
The AP 8120 with External Antenna is designed for indoor use only and must not be used
outdoors.
Warning:
The AP 8120 with External Antenna must be installed by a professional installer. Read and
follow all warning notices and instructions on the product or included in the documentation.

The mounting bracket is designed to use wall anchors with threaded section diameters ranging
between 3.5mm and 4.5mm. If wall anchors have threaded diameters greater than 3.5mm, only the
two mounting holes marked ‘A’ may be used. If wall anchors have threaded diameters of less than
3.5mm, the holes marked ‘A’ and the holes marked ‘B’ may be used. All wall anchors must have a
head diameter of less than 10mm or the wall mounting bracket cannot be installed over them.
Perform the following procedure to mount a wireless LAN access point on a wall:
Procedure
1. Locate the appropriate position of the wall anchors. The wall anchors should be 95mm apart
horizontally and 80mm apart vertically.
June 2014 Installation Job Aid (English) for Avaya WLAN 8100 series- WLAN AP 8120 with External Antenna 3

The wall bracket is designed to use a minimum of 2 anchors and a maximum of 4.
2. Install the screws into the wall anchors but do not seat them fully, leave at least a 2mm gap
between the screw head and the wall.
3. Slip the wall bracket over the heads of the screws and slide the bracket to the right as
viewed facing the wall.

4. Tighten the screws to secure the wall mounting bracket tightly against the wall.
5. Align the mounting tabs on the bottom of the access point sheet metal enclosure with the
vertically oriented keyhole slots in the mounting bracket.

6. Allow the access point to slide down the keyhole slots, making sure the access point
mounting tabs are seated at the bottom of the slot.
7. Secure the access point to the wall mounting bracket and tighten the thumbscrews.
8. Verify that the access point is secured to both the bracket and to the wall.
9. Mount the external antennas to the wall within the specified distance from the access point.
If you are installing Laird antennas, you can mount the antennas on a mast or vertical
surface (wall) using the articulated mount and mounting bolts.

If you are installing TYCO antennas, attach mounting brackets to the wall and attach the
antennas to the mounting brackets.

10. Verify that the antennas are securely mounted to the wall (or mast, in the case of a Laird
antenna installation).
11. Attach the antenna cables to the access point.
Use the following table to match the 180 degree TYCO antenna and the 70 degree Laird antenna
connectors to the AP8120 - with External Antenna inputs with the cables. The 180 degree TYCO
antenna connectors are labeled the same as the AP8120 - with External Antenna inputs.

Installing the WLAN AP 8120 with External Antenna to the ceiling
About this task
The WLAN AP 8120 with External Antenna installs similarly to the WLAN AP 8120. In addition to
installing the access point itself, with the WLAN AP 8120 with External Antenna you must also
mount the adjoining antennas. You can mount the WLAN AP 8120 with External Antenna on the
ceiling using a ceiling grid adaptor.
Plan your installation to allow for the installation of both the access point and the antennas. Ensure
you have the correct length of cable to connect the access point to the antennas. Each antenna
comes with three 3–ft pre-installed permanent cables. If your installation distance is greater than the

The ceiling grid adaptor comes with two interlocking bracket parts. The larger bracket includes
keyhole shaped slots which mate with tabs on the under surface of the AP and a threaded hole that
mates with the captive thumbscrew on the AP. The smaller bracket also includes a captive fastener
and it can be oriented with respect to the larger bracket in two different ways corresponding to
narrow or wide ceiling grids.
Perform the following procedure to install the access point with a ceiling grid adaptor:
Procedure
1. Secure a safe work environment. Obtain a ladder that allows easy access to the ceiling grid
system.
2. Identify an appropriate location on the ceiling grid where the ceiling T-bars are safely
accessible and where the ceiling tiles can be temporarily elevated and cleared away from the
June 2014 Installation Job Aid (English) for Avaya WLAN 8100 series- WLAN AP 8120 with External Antenna 8

work area. The adaptor bracket assembly is intended for use with the thin section grid
runners, not the thicker section runners used to cross large spans. To provide access for
hands and tools, use a pair of pencils or sticks to hold up the ceiling tiles out of the grid.
Doing this provides easy access for securing the bracket to the grid.
3. Mount the larger bracket to the grid. While installing, pay attention to the width of the grid
strip in order to ascertain the appropriate orientation for the smaller bracket which is installed
next.
4. Mount the interlocking small bracket to the large bracket and clamp the two pieces together
on the grid. The smaller bracket has tabs formed into it which engage slots in the larger tab.
This allows the two parts to slide together and lock to one another. When this is done, the
two brackets effectively clamp themselves around the ceiling grid. When the two halves of
the bracket are correctly slid together, the captive fastener in the small bracket should
engage threads provided in the larger bracket. Use a screwdriver to screw down the captive
fastener. Securing the two brackets in this manner is essential to prevent them from
disengaging from one another. Tighten the captive fastener screw securely.

5. Attach the access point to the bracket. Align the access point securing tabs with the keyhole
slots in the ceiling grid bracket and carefully slide the access point onto the ceiling grid
bracket assembly. If the access point and the bracket assembly are correctly engaged, it
should be possible to engage the access points captive thumbscrew into the threaded tab
provided on the ceiling grid bracket.
6. Mount the external antennas to the wall within the specified distance from the access point.
