Installation reference
Access Point 8120 overview
            The Avaya Access Point 8120 (AP 8120) is the wireless access portion of
            the Avaya WLAN 8100 Series solution. The AP 8120 provides 802.11a+n
            b/g+n wireless connectivity through six dual-band 2.4/5.0 GHz antennas;
            three dedicated to 2.4 GHz use and three dedicated to 5.0 GHz . The AP
            8120 is designed for use with the Wireless Controller 8180 (WC 8180).
            The WC 8180 coordinates and load balances domains of access points in
            the network.

            The AP 8120 communicates with the WC 8180 using a standard Category
            5 (CAT-5) or higher 10/100/1000Mbps twisted pair Ethernet cable. The
            AP 8120 is intended for indoor installations only. It does not accept the
            connection of external antennas.

            The AP 8120 requires hardware installation only. Access point
            configuration is performed on the WC 8180 after installation and
            connection to the network.

Installation preparation
Unpacking the access point
           The shipping carton for an AP contains the following items:
           •   one AP
           •   mounting kit
               — one universal mounting bracket (attached to the AP)
               — one dual size (15/16 and 5/8 inch) T-bar clamp
               — one mounting bracket that attaches to the T-bar clamp and AP
               — four adhesive rubber feet
           •   Avaya WLAN 8100 - Regulatory Information - AP 8120 document

           Verify that the items removed from the shipping carton correspond to the
           provided list. If an item is missing or damaged, contact Avaya.

Cabling requirements
           The AP 8120 access point has one RJ-45 port. This port provides a
           10/100/1000BASE-TX Ethernet connection to a Wireless Controller 8180.
           This port is used to indirectly connect an access point to a WC 8180
           through an intermediate Layer 2 or Layer 3 network.

           The access point can receive power and data through the RJ-45 port. Use
           a Category 5 (CAT-5) cable with straight-through signaling and standard
           RJ-45 connectors to connect to a network device. The AP 8120 supports
           802.3af. An Avaya-approved power injectors must be used to provide the
           access point with power over the Ethernet cable. The WC 8180 has no
           PoE capabilities.

           The Ethernet port 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.

12 Installation preparation




                                                                      840-9502-0067
                  Uneven sheath




                  You must operate the access point with a CAT-5 Ethernet cable installed
                  on the Ethernet port to ensure compliance with the Class B emissions
                  standards. Failure to comply with this installation requirement can cause
                  the device to operate in excess of the allowable emissions limits.



                  Attention: The AP 8120 access point is intended for indoor use only. Do
                  not install the device or operate it outdoors.




                  Attention: To reduce the possibility of connection interference caused by
                  dust, clean the CAT-5 connector pins before inserting a cable into an AP.


                  The following table lists the pin signals for the 10/100/1000 Ethernet
                  straight-through wiring. Pins 4, 5, 7, and 8 are used when Avaya Power
                  over Ethernet (PoE) is enabled on the port.

Management software
            If you are using the WLAN Management Software (WMS) to plan your
            Avaya Mobility System installation, you can create and verify a network
            plan for the entire Avaya network installation and generate an AP work
            order, before installing any access points.

Network plans and work orders
            A network plan and the AP work orders provide the following information
            about AP installation and configuration:
            •   number of APs required for adequate WLAN capacity in each coverage
                area
            •   detailed installation locationfor each AP
            •   settings for all APs in the WLAN

            For information about installing WLAN Management Software , creating
            and verifying a network plan, and generating an AP work order, see the
            Avaya WLAN 8100 - Planning and Engineering document.

      Wireless Controller 8180 recommendation
            Avaya recommends that you install and configure the Wireless Controller
            8180 before installing an AP. If the switch is already installed and
            configured for the access points, you can immediately verify the cable
            connection when you plug the cable into the RJ-45 port on the AP.
                            CAUTION
                            AP 8120 access points are designed to receive power only
                            from an 802.3af-compliant source or an Avaya-approved
                            power injector. Connecting an AP to a Power over Ethernet
                            (PoE) device that is not approved by Avaya can damage the
                            equipment.

            For more information about connecting an AP to a WC 8180 port, see
            Connecting to a Wireless Controller 8180.

      Wall installation recommendations
            If you plan to install an AP on a partial wall or other vertical surface, orient
            the top of the access point (the side with the LEDs) toward the intended
            coverage area. The radio antennas transmit through the top of the access
            point but not through the bottom (where the bracket is located).

Radio safety advisories
            When you enable the AP radios as part of a configuration, the radios can
            receive and transmit radio frequency energy as soon as you connect the
            AP to the WC 8180, either directly or through the network.

Access Point 8120 installation
            This section contains procedures for the installation of the Access Point
            8120.

Mounting a wireless LAN access point on a wall
            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 steps

            Step      Action

            1         Locate the appropriate position of the wall anchors. The wall
                      anchors should be 95mm apart horizontally and 80mm apart
                      vertically.

            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.

Installing an Access Point with a ceiling grid adaptor
            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:

18 Access Point 8120 installation


        Procedure steps

                 Step       Action

                 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 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.

                      Installing an Access Point with a ceiling grid adaptor   19




    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   Make electrical connections and return ceiling tiles.

Access Point Troubleshooting
      After you insert the CAT-5 cable into an AP’s port connector and enable
      PoE on the cable, observe the device’s health or link LED to determine the
      status of the connection with the WC 8180.
      •     If the LED is green and is glowing steadily, the AP was booted
            successfully by the WC 8180 and is ready for operation.
      •     If the LED is not steadily glowing green, see the following table.

      For descriptions of all the LEDs, see "Status Light-emitting diode (LED)"
      (page 10).

Common antenna terminology
           The following glossary includes basic antenna terminology that can help in
           the selection and recommendation of a particular antenna.

    Omnidirectional (Omni)
           Refers to the antenna coverage pattern. An omnidirectional antenna
           creates a uniform coverage pattern. Most omnidirectional antennas
           are weakest directly above and directly below their endpoints — this
           characteristic creates the familiar dual-lobe pattern shown on the E-plane
           graphs. Nulls are typically related to the orientation of the dipole/monopole
           antenna relative to the horizontal or vertical planes. The lobes grow and
           shrink depending upon the ground plane effects and cancellation/addition
           of the radiating signal. Omnidirectional antennas are suitable for most
           general deployments.

    Directional
           Refers to the antenna coverage pattern. A directional antenna focuses its
           lobe or radiated energy in a particular direction. In general, as the gain of a
           directional antenna increases, the radiating beamwidth or lobe decreases.
           This design increases the transmitted power and communication distance
           in a specific direction at the expense of uniform coverage, as compared
           to an omnidirectional antenna. You must aim a directional antenna at the
           intended coverage zone.

    Gain
           Expressed in dBi, indicates the relative increase in radiated power over an
           isotropic point radiating source with a reference gain of 1.0.

           Each 3 dB increment in power effectively doubles the radiated energy. For
           example, an antenna with a gain of 9 dBi increases the transmit power 8
           times more than an isotropic point radiating source. For example

           12.5 mW = 11 dBm
           11 dBm + 9dBi = 20 dBm
           20 dBm = 100 mW
           100mw/12.5 mW = 8 times more power

       E-Plane graph
               The elevation plane graph shows the radiated antenna coverage pattern
               as a vertical cross section — as if looking directly at the antenna from the
               side.

       H-Plane graph
               The horizontal plane graph shows the radiated antenna coverage pattern
               as a horizontal cross section — as if looking directly at the antenna from
               above.
