Chapter 1
Hardware Overview
About the Aruba AP-80SB and AP-80MB
The Aruba AP-80 MB/SB Outdoor Wireless Access Point/Bridges are dual-radio outdoor-rated wireless
access points/Wireless Distribution System (WDS) bridges that are designed for the deployment of
advanced IEEE 802.11 wireless services in harsh environments.
As an outdoor wireless access point, the AP-80 MB and AP-80SB can provide IEEE 802.11 wireless
service to local wireless clients. The AP-80SB provides 802.11b/g service only, while the AP-80MB can
provide 802.11a/b/g services simultaneously.
When deployed for wireless bridging, two or more AP-80 MB/SB models provide point-to-point or point-
to-multipoint bridge links between remote Ethernet LANs, and can simultaneously serve wireless
service for local clients on the non-bridging radio. The wireless bridge system offers a fast, reliable, and
cost-effective solution for connectivity between remote Ethernet LANs or to provide Internet access to
an isolated site.
The AP-80SB and AP-80MB are stand-alone devices that operate independent of an Aruba Mobility
Controller. They provide the following capabilities:
AP-80SB
zStand-alone wireless access point (802.11b/g) with support for wireless backhaul over 5 GHz
zPoint-to-point WDS bridge for 5 GHz or 2.4 GHz
zIntegrated 17dBi 5GHz directional panel antenna (for bridging or wireless backhaul purposes only)
zTwo 2.4 GHz N-type female detachable antenna interfaces
AP-80MB
zStand-alone wireless access point (802.11a/b/g) with support for wireless backhaul over either 5
GHz or 2.4 GHz

External Antenna Options
zBoth AP-80SB and AP-80MB models support a variety of certified, detachable antenna options.
When performing wireless bridging, the AP-80SB offers an integrated 5GHz, 17dBi 30 degree beam-
width panel antenna for point-point radio link communications.
The AP-80SB integrated antenna is primarily designed for WDS bridging applications only and therefore
is not ideally suitable for serving wireless clients. The AP-80SB only supports detachable antennas for
the 2.4 GHz band.
The AP-80MB does not include an integrated antenna, but provides instead one 2.4 GHz and one 5 GHz
N-type detachable antenna interface. In a point-to-multipoint configuration, an external high-gain
omnidirectional, sector, or high-gain panel antenna can be attached to communicate with wireless
bridges spread over a wide area and from differing directions.
The AP-80SB and AP-80MB units both require a suitable 2.4 GHz external antenna for 2.4 GHz wireless
client serving operation.
Power over Ethernet Injector/Adapter
All Aruba AP-80 MB/SB models are required to be powered over Ethernet using the supplied power over
Ethernet injector/adapter. The power injector provides two RJ-45 Ethernet ports (illustrated below):
one for connecting to the AP-80 MB/SB (AP), and one for connecting to a local LAN switch (ENET).
5 RSSI Connector
The Receive Signal Strength Indicator (RSSI) BNC connector provides a DC low output voltage
that is proportional to the received radio signal strength. A DC voltmeter can be connected to this
port to assist in aligning the antennas at both ends of a wireless bridge link.
6GroundingScrew
Even though the AP-80 MB/SB includes its own built-in lightning protection, it is important that the
unit is properly connected to ground. A grounding screw is provided for attaching a ground wire to
the unit.
The AP-80 MB/SB requires lightening protection. Aruba recommends the use of lightening
arresters. Failure to provide protection from lightening strikes will void the warranty for this
product.

Figure 3 Power over Ethernet Injector/Adaptor
The AP-80 MB/SB does not have a power switch and is powered on when its Ethernet port is connected
to the power injector, and the power injector module is connected to an AC power source. The power
injector includes one LED indicator that turns on when AC power is applied.
The power injector module automatically adjusts to any AC voltage between 100-240 volts at 50 or 60
Hz. No voltage range settings are required.
The Ethernet port uses an MDI (internal straight-through) pin configuration. You can use a straight-
through twisted-pair cable to connect the Ethernet port to most network interconnection devices (such
as a switch or router) that provide MDI-X ports.

Chapter 2
Installation
Installation Overview
The Aruba AP-80 MB/SB Outdoor Wireless Access Point/Bridge is designed to be deployed outdoors,
exposed to all elements (extreme heat or sun, rain, snow, ice, cold) and mounted on a wall, pole, or
mast. The AP-80 MB/SB is supplied complete with its own mounting hardware kit for attaching the unit
to a 1.5” to 2” diameter steel pole or tube or as part of a radio mast or tower structure.
The Aruba AP-80 MB/SB indoor-rated Power over Ethernet injector (model AP-AC-80-1) must be
deployed indoors, or within an enclosure protecting it from the elements.
AP-80 MB/SB Setup Process
Setting up an AP-80SB or AP-80MB device consists of the following steps:
1. WLAN planning: The network administrator determines how many AP-80 MB/SBs are needed for
their wireless network strategy and where they will be deployed, deciding on an appropriate radio
band and channel plan to accommodate the deployment needs.
WLAN planning is discussed in more detail in Chapter 3, “Planning and Deployment
Considerations.”
2. AP provisioning: This is typically performed at a staging facility in a safe location, where the AP-80
MB/SBs are easily accessible by the network administrator and can be verified as fully operational
and provided with configuration settings prior to physical installation of the device. AP-80 MB/SB
provisioning is discussed in more detail in Chapter 3, “Planning and Deployment Considerations.”
3. AP-80 MB/SB installation: Once provisioned, each AP-80 MB/SB can be physically installed at its
intended place of operation. See “AP-80MB/SB Installation” on page 17.
4. Additional AP-80 MB/SB configuration/maintenance: The administrator may now remotely alter
configuration and maintain the AP-80 MB/SB (for example, monitoring the device and updating
software versions) via remote Telnet or WebUI. Configuring and maintaining the AP-80 MB/SB is
discussed in more detail in Chapter 5, “Advanced Configuration.”.
AP-80MB/SB Installation
Hardware installation involves these tasks, as described in this chapter:
1. Mount the unit on a wall, pole, mast, or tower using the mounting bracket.
2. Mount external antennas on the same supporting structure as the bridge and connect them to the
bridge unit.
3. Connect the Ethernet cable and a grounding wire to the unit.
4. Connect the power injector to the Ethernet cable, a local LAN switch, and an AC power source.
NOTE
Due to the typically remote, hostile environmental or precariously positioned location of the installed
device, Aruba recommends that the AP-80 MB/SB be fully provisioned in advance of physical
installation.

18 |Installation Aruba AP 80 Outdoor Wireless Access Point/Bridge | Installation and User Guide
5. Align antennas at both ends of the link.
Before mounting antennas to set up your wireless bridge links, be sure you have selected appropriate
locations for each antenna. Follow the guidance and information in Chapter 3, “Planning and
Deployment Considerations.”
Also before mounting units in their intended locations, you should first configure the devices as
described in Chapter 4, “Provisioning and Initial Setup” and Chapter 5, “Advanced Configuration.” You
should also test the basic operation of the wireless bridge links in a controlled environment over a very
short range, as described in “Staging the Installation” on page 18.
Preparing for Installation
Before installing your Aruba AP-80 MB/SB Outdoor Wireless Access Point/Bridge, verify that you are
supplied and prepared with the following items:
zOne Outdoor Ethernet cable of required length of 50 meters (164 feet), or a cable meeting the pin-out
configuration specification to the required length (not to exceed 90 meters total), shielded CAT-5
Ethernet 8-pin DIN to RJ-45
zOne power adapter shipped with the Aruba AP-80 MB/SB
zAn appropriate and stable mounting location
zA suitable electrical grounding point (on mounting mast/pole)
zAppropriate tools (wrench for mounting bolts, phillips head screwdriver, DC voltmeter (if RSSI-
based link alignment is to be performed))
Mounting items not supplied with the AP-80MB/SB — screws, bolts, and straps — should be available
and at hand prior to installation.
Due to the typically inaccessible location often best suited to deploying an outdoor wireless bridge (for
example, on rooftops, sides of buildings, or on a radio tower) it is recommended that the network
administrator pre-provision the AP-80 MB/SB system to be installed (taking note of settings, passwords,
MAC and IP addresses) prior to physical installation, and confirm that the device is fully operational
and free from fault.
Staging the Installation
Set up the units over a very short range (15 to 25 feet), either outdoors or indoors. Connect the units as
indicated in this chapter and be sure to perform all the basic configuration tasks outlined in Chapter 4,
“Provisioning and Initial Setup” When you are satisfied that the links are operating correctly, proceed to
mount the units in their intended locations.
Mounting the Unit
Using the Pole-Mounting Bracket
Perform the following steps to mount the unit to a 1.5 to 2 inch diameter steel pole or tube using the
mounting bracket:
1. Always attach the bracket to a pole with the open end of the mounting grooves facing up.
W
ARNING
Do not work on the AP-80 MB/SB or connect or disconnect cables during periods of lightening
activity.

Aruba AP 80 Outdoor Wireless Access Point/Bridge | Installation and User Guide Installation | 19
2. Place the U-shaped part of the bracket around the pole and tighten the securing nut just enough to
hold the bracket to the pole (Figure 4). (The bracket may need to be rotated around the pole during
the alignment process.)
Figure 4 Pole Mounting
3. Use the included nuts to tightly secure the wireless bridge to the bracket. Be sure to take account of
the antenna polarization direction; both antennas in a link must be mounted with the same
polarization (Figure 5).
Figure 5 Attaching the AP-80 MB/SB to a Pole.
Mounting on Larger Diameter Poles
There is a method for attaching the pole-mounting bracket to a pole that is 2 to 5 inches in diameter
using an adjustable steel band clamp (not included in the kit). A steel band clamp up to 0.5 inch (1.27
cm) wide can be threaded through the main part of the bracket to secure it to a larger diameter pole
without using the U-shaped part of the bracket. This method is illustrated (Figure 6).
