ATTENTION!Special Considerations
While Airespace Access Points have been engineered for easy installation, there are some guidelines
that are very important to the end users:
•PLACE Airespace Access Points NO MORE THAN 140 FEET APART FROM EACH OTHER. Placing
Airespace APs further apart almost always results in poor coverage.
•DO NOT MOUNT Airespace APs OUTSIDE BUILDINGS.
•DO NOT MOUNT Airespace APs ON BUILDING PERIMETER WALLS UNLESS THE OPERATOR
WANTS TO PROVIDE COVERAGE OUTSIDE THE BUILDING.
•MAKE SURE that plenum-mounted Airespace APs are powered using Power Over Ethernet (POE)
and use only the metal brackets (not the Ceiling-Mount Base or the Hanging-Ceiling Clips) to
comply with safety regulations.
•MAKE SURE THAT THE Airespace Access Points ARE INSTALLED VERTI-
CALLY. Airespace Access Points ARE DESIGNED TO BE INSTALLED
VERTICALLY, either standing up in a plenum or hanging from a ceiling,
to create the largest coverage area per Airespace AP. Hanging the
Airespace AP from the ceiling provides the best RF coverage.
12/29/04 Overview
90-100tbd-000 Rev 1 (Preliminary 3) 2
•DO NOT MOUNT Airespace Access Point ANTENNAS WITHIN ONE METER (3 FT.) OF ANY METAL
OBSTRUCTIONS. THE RF WAVES FROM Airespace Access Points ARE BLOCKED AND/OR
REFLECTED BY METAL OBJECTS, such as metal HVAC ducts, conduit, pipes, bookcases, elevator
shafts, stairwells, and metal walls. REFER TO THE Airespace Access Point Deployment Guide
BEFORE MOUNTING Airespace APs NEAR METAL OBSTRUCTIONS.
OverviewOverview
This guide is designed to provide you with the information needed to mount AS 1500 Airespace Access
Points (Airespace APs). Airespace APs are part of the innovative Airespace Wireless Enterprise Platform
(Airespace System), and require no manual configuration after they are mounted.
This document assumes that a site survey has been performed as described in the Airespace Access
Point Deployment Guide section in the Airespace Product Guide, that Airespace AP locations have been
selected, and that you have one Airespace AP per indicated location.
After the site survey is done, you should have a map indicating the following:
•AP locations in the middle of a ceiling or hallway.
•AP power options: power supplied by the AC-to-DC power supply orderable from the factory, or
Power over Ethernet (PoE) from the Airespace WLAN Switch, another network device, or a PoE
injector/hub (usually located in a wiring closet).
If you do not have a map, make one so you can record the MAC addresses from each location and
return them to the to the person who is planning or managing this wireless network.
Refer to the following sections to install the Airespace APs.
For more details about Airespace AP installations, refer to the Planning Notes section at the end of this
document.
Step 1: Collecting Required Tools and SuppliesStep 1: Collecting Required Tools and Supplies
•One Airespace AP per location with included mounting clips.
•Optional Airespace AP Mounting Kits, factory-orderable.
•Optional external AC-to-DC power supplies, factory-orderable.
•Map showing Airespace AP locations and power options.
•Screwdrivers, drills, and ladder.
•CAT-5 (or higher) cables to connect the Airespace AP locations and the Airespace WLAN Switch
or other network device.
Continue with Step 2: Configuring the Airespace AP Before Installation.
Note: Plenum-mounted Airespace APs and REAPs MUST BE powered using Power
Over Ethernet (POE) to comply with safety regulations.
Note: When mounting Airespace APs, make sure to maintain a 20 cm (8 in.) separa-
tion between the Airespace APs and bystanders to comply with FCC RF exposure
regulations. Refer to the FCC Statements for Airespace APs section for more
information.

90-100tbd-000 Rev 1 (Preliminary 3) 3
Step 2: Configuring the Airespace AP Before InstallationStep 2: Configuring the Airespace AP Before Installation
The following procedures are designed to make sure that your Airespace AP physical installation goes
smoothly and that initial operation is as expected. If you are unable to prepare your Airespace AP for
deployment, this Step also describes RMA (Return Material Authorization) procedures.
Configuration SetupConfiguration Setup
Configuration Steps for an Airespace APConfiguration Steps for an Airespace AP
1. Configure the Airespace Switch or Appliance for LWAPP Layer 2 Mode (use the CLI command
show switchconfig to determine the mode; if it is set to layer 3, use the CLI command config
switchconfig mode L2 to change it to Layer 2). Make sure the Airespace Switch or Appliance DS
Port is connected to the network. Use CLI, Web Browser and/or ACS procedures as described in
the Airespace Switch and Appliance Quick Installation GuideAirespace Switch and Appliance
Quick Install Guide and the Airespace Product GuideAirespace Product Guide.
-Make sure AP ports are available (either Direct-Connect Mode through the Switch
physical ports, or in Appliance Mode through the Airespace Switch or Appliance
Management/AP-Manager Interface).
-Set the Airespace Switch or Appliance as the Master, so new Airespace APs always
associate with it. Use the CLI command show network config to determine if the
Airespace Switch or Appliance DS Port is the Master. If it is not, make it the Master with
the CLI command config network master-base enable. Make sure to use the CLI
command config network master-base disable after you have configured the AP(s).
-Refer to the Airespace Product Guide for other settings.
2. Take the Airespace AP out of the box and plug it into a front-panel 10Base-T connector on the
Master Switch (Direct-Connect Mode), or through the same subnet that Airespace Switch or
Appliance is on (Appliance Mode).
3. Apply power to the AP:
-Use 802.3af-compatible Power Over Ethernet (PoE) from the Airespace Switch or
Appliance or from an orderable inline power injector. If you do not have PoE available,
use an orderable external AC-to-48 VDC Power Supply plugged into the side of the AP.
-After powering up the AP, the RED Alarm LED comes on for a short period (about 15-20
seconds) and then all the LEDs blink sequentially back and forth, indicating that the AP
is trying to connect to an Airespace Switch or Appliance. This can continue for up to five
Note: Perform the following procedure on each Airespace AP BEFORE deploying the
Airespace AP in its final location.
12/29/04 Step 2: Configuring the Airespace AP Before Installation
90-100tbd-000 Rev 1 (Preliminary 3) 4
minutes. If the AP remains in this mode for more than five minutes, the AP is unable to
find the Master Airespace Switch or Appliance. Check the connection between the AP
and the Airespace Switch or Appliance and make sure the Airespace AP and the
Airespace Switch or Appliance are on the same subnet.
-If the Power light does not come on, check the power (it can be powered either with
Power over Ethernet or a from an orderable AP External Power Supply.
-Make sure that a DHCP server is configured in the Airespace Switch or Appliance for
both the Management Interface and AP-Manager Interface using the CLI, Web Browser,
or ACS interface, and that the DHCP server is operating correctly.
-Once the AP finds the Airespace Switch or Appliance, it attempts to download the new
Airespace Operating System code if the AP code version differs from the Airespace
Switch or Appliance code version. While this is happening, the LEDs on the top of the
AP blink on and off together.
4. Once the Airespace Operating System code download is successful, the AP reboots. The GREEN
LED turns on and the two AMBER/AMBER LEDs indicate the states of the 802.11a and 802.11b/
g networks. If a AMBER/AMBER LED remains off.
-Note that the Red LED can light for a short period (10-20 seconds) when the AP
reboots. If the RED LED comes on AND STAYS ON for more than a minute, disconnect
the AP and call Airespace Global Services & Support.
-Use the CLI command show ap summary. If the new AP appears on the list, it has been
configured successfully.
-From the CLI, Web Browser or ACS interface, configure the AP with its Primary,
Secondary and Tertiary Airespace Switch or Appliance names as described in the
Airespace Product Guide.
-If you will be using the AP in a mobility or a WPS group, set the mobility or WPS group
name using the CLI, Web Browser or ACS interface.
-If required, use the CLI, Web Browser or ACS interface to customize the AP-specific
802.11a, 802.11b and 802.11g network settings. Once again, the two AMBER/AMBER
LEDs indicate the states of the 802.11a and 802.11b/g networks. If any part of the
network is disabled, the corresponding AMBER/AMBER LED remains off.
5. If everything works correctly (the GREEN LED is on and the RED LED is off), disconnect the
Airespace AP and take it to its final destination and install it as described in this document. If
your Airespace AP fails this visual test, refer to RMA Procedures in the Airespace Product Guide
to return your Airespace APs.
6. When you have installed and powered up the Airespace AP in its final destination, verify that
the LEDs are in the same state they were in at the end of Step 4.
-If no LEDs are on, the AP is most likely not receiving power.
-If the LEDs blink sequentially back and forth for more than five minutes, the Airespace
AP is unable to find its Primary, Secondary or Tertiary Airespace Switch or Appliance.
Check the connection between the Airespace AP and the Airespace Switch or Appliance,
and make sure the AP and the Airespace Switch or Appliance are either on the same
subnet or that the AP has a route back to its Primary, Secondary and Tertiary Airespace
Switches and Appliances.
-If the Airespace AP is not on the same subnet as the Airespace Switch or Appliance,
make sure there is a DHCP server on the same subnet as the Airespace AP. Also, make
sure that the route between the Airespace AP and the Airespace Switch or Appliance
can process IP fragmented packets.
12/29/04 Step 3: Preparing Mounting Locations
90-100tbd-000 Rev 1 (Preliminary 3) 5
After you have prepared all Airespace APs, reconfigure the Airespace Switch or Appliance so it is not the
Master. A Master Airespace Switch or Appliance should only be used for configuring Airespace APs and
not in a working network. Note that the Master Airespace Switch or Appliance is normally not used in a
deployed network, so the Master Airespace Switch or Appliance setting is automatically disabled upon
reboot or AireOS code upgrade.
After completing Step 2: Configuring the Airespace AP Before Installation for all Airespace APs and
REAPs, continue with Step 3: Preparing Mounting Locations.
Step 3: Preparing Mounting LocationsStep 3: Preparing Mounting Locations
On your map, you should have the Airespace AP locations, mounting options, and power options.
•Find the required mounting locations.
Figure - Factory-Supplied Mounting Clips
•Attach the hanging ceiling clips to the Airespace AP. Make sure you leave enough space around
the Airespace AP to plug the CAT-5 cable, optional external antenna cable(s), optional power
supply cable, and optional Kensington MicroSaver Security Cable into the sides of the Airespace
AP.
•Alternatively, use the optional mounting bases and/or brackets to mark the wall or ceiling
locations for sheet metal, drywall, or other screws. Make sure you leave enough space around
the Airespace AP and brackets to plug the CAT-5 cable, optional external antenna cable(s),
optional power supply cable, and optional Kensington MicroSaver Security Cable into the sides
of the Airespace AP.
Note: MAKE SURE that plenum-mounted Airespace APs use only the metal Projec-
tion-Mount and Flush-Mount brackets (not the Hanging-Ceiling Clips) and are
powered using Power Over Ethernet (POE) to comply with safety regulations.
12/29/04 Step 3: Preparing Mounting Locations
90-100tbd-000 Rev 1 (Preliminary 3) 6
Figure - Factory-Orderable Mounting Brackets
•If necessary, drill holes for the various cables where they can be mostly hidden from casual
view. When you are mounting the Airespace AP using an optional separately-orderable
projection-mount L-bracket (the one with two long legs), the cables can be routed through the
5/8-inch (15.9 mm) holes in the bracket.
•Route the CAT-5, optional power supply, optional external antenna cable(s), and optional
Kensington MicroSaver Security cables to where they can plug into the Airespace AP. Make sure
to leave about 6 inches (15 cm) of slack in the cables for future modifications.
•Attach the brackets to the wall or ceiling, or install screws for ceiling-mount base:
-Where you are going to use the projection-mount or flush-mount bracket, use
customer-supplied sheet metal, drywall, or other screws to attach the bracket to the
ceiling or wall.
•Where you are going to use the ceiling-mount base, install customer-supplied sheet metal,
drywall, or other screws with 1/4 inch (6.35 mm) or smaller heads protruding from the ceiling
about 0.1 inch (2.5 mm).
•If necessary, drill holes for the various cables where they can be mostly hidden from casual
view.
•Route the CAT-5, optional power supply, optional external antenna cable(s), and optional
Kensington MicroSaver Security cables to where they can plug into the Airespace AP. Make sure
to leave about 6 inches (15 cm) of slack in the cables for future modifications.
You are now ready to install the Airespace APs. Continue with Step 4: Mounting the Airespace APs.

About CablesAbout Cables
•You will run one CAT-5 Ethernet cable from the Airespace AP to the Airespace WLAN Switch,
another network device, or a PoE injector/hub.
When the Airespace AP will be mounted below the ceiling using the ceiling mount or wall mount
brackets, you may have to drill a hole into the ceiling plenum to run the CAT-5 cable to the wir-
ing closet. When the CAT-5 cable cannot be run through the ceiling plenum, find another path
to route the cable from the Airespace AP to the wiring closet.
When the Airespace AP will be mounted above the ceiling using the ceiling mount or wall mount
brackets, run the CAT-5 cable to the wiring closet through the ceiling plenum. When the CAT-5
cable cannot be run through the ceiling plenum, find another path to route the cable from the
Airespace AP to the wiring closet.
•When you are powering the Airespace AP from AC power, route the power supply cable from
the AC convenience outlet to the Airespace AP. Make sure you secure the AC power plug so it
will be difficult for people to pull on the power cord or unplug the power supply from the AC
power outlet.
•When you are powering the Airespace AP from a PoE source (Airespace WLAN Switch, another
network device, or a PoE injector/hub), you do not need to route a separate power cable to the
Airespace AP, because the Airespace AP will receive its power across the CAT-5 Ethernet cable.
