15.Access Point 8120 installationThis section contains procedures for the installation of the Access Point8120.Mounting a wireless LAN access point on a wallThe mounting bracket is designed to use wall anchors with threadedsection diameters ranging between 3.5mm and 4.5mm. If wall anchorshave threaded diameters greater than 3.5mm, only the two mounting holesmarked ‘A’ may be used. If wall anchors have threaded diameters of lessthan 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 wallmounting bracket cannot be installed over them.Perform the following procedure to mount a wireless LAN access point ona wall:Procedure stepsStep Action1Locate the appropriate position of the wall anchors. The wallanchors should be 95mm apart horizontally and 80mm apartvertically.Avaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.
16 Access Point 8120 installationThe wall bracket is designed to use a minimum of 2 anchors anda maximum of 4.2Install 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.3Slip the wall bracket over the heads of the screws and slide thebracket to the right as viewed facing the wall.4Tighten the screws to secure the wall mounting bracket tightlyagainst the wall.5Align the mounting tabs on the bottom of the access point sheetmetal enclosure with the vertically oriented keyhole slots in themounting bracket.Avaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.
Installing an Access Point with a ceiling grid adaptor 176Allow the access point to slide down the keyhole slots, makingsure the access point mounting tabs are seated at the bottomof the slot.7Secure the access point to the wall mounting bracket and tightenthe thumbscrews.8Verify that the access point is secured to both the bracket andto the wall.--End--Installing an Access Point with a ceiling grid adaptorThe ceiling grid adaptor comes with two interlocking bracket parts. Thelarger bracket includes keyhole shaped slots which mate with tabs on theunder surface of the AP and a threaded hole that mates with the captivethumbscrew on the AP. The smaller bracket also includes a captivefastener and it can be oriented with respect to the larger bracket in twodifferent ways corresponding to narrow or wide ceiling grids.Perform the following procedure to install the access point with a ceilinggrid adaptor:Avaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.
18 Access Point 8120 installationProcedure stepsStep Action1Secure a safe work environment. Obtain a ladder that allowseasy access to the ceiling grid system.2Identify an appropriate location on the ceiling grid where theceiling T-bars are safely accessible and where the ceiling tilescan be temporarily elevated and cleared away from the workarea. The adaptor bracket assembly is intended for use with thethin section grid runners, not the thicker section runners used tocross large spans. To provide access for hands and tools, use apair of pencils or sticks to hold up the ceiling tiles out of the grid.Doing this provides easy access for securing the bracket to thegrid.3Mount the larger bracket to the grid. While installing, payattention to the width of the grid strip in order to ascertain theappropriate orientation for the smaller bracket which is installednext.4Mount the interlocking small bracket to the large bracket andclamp the two pieces together on the grid. The smaller brackethas tabs formed into it which engage slots in the larger tab. Thisallows the two parts to slide together and lock to one another.When this is done, the two brackets effectively clamp themselvesaround the ceiling grid. When the two halves of the bracket arecorrectly slid together, the captive fastener in the small bracketshould engage threads provided in the larger bracket. Use ascrewdriver to screw down the captive fastener. Securing thetwo brackets in this manner is essential to prevent them fromdisengaging from one another. Tighten the captive fastenerscrew securely.Avaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.
Installing an Access Point with a ceiling grid adaptor 195Attach the access point to the bracket. Align the access pointsecuring tabs with the keyhole slots in the ceiling grid bracketand carefully slide the access point onto the ceiling grid bracketassembly. If the access point and the bracket assembly arecorrectly engaged, it should be possible to engage the accesspoints captive thumbscrew into the threaded tab provided on theceiling grid bracket.6Make electrical connections and return ceiling tiles.--End--Avaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.

27.Common antenna terminologyThe following glossary includes basic antenna terminology that can help inthe selection and recommendation of a particular antenna.Omnidirectional (Omni)Refers to the antenna coverage pattern. An omnidirectional antennacreates a uniform coverage pattern. Most omnidirectional antennasare weakest directly above and directly below their endpoints — thischaracteristic creates the familiar dual-lobe pattern shown on the E-planegraphs. Nulls are typically related to the orientation of the dipole/monopoleantenna relative to the horizontal or vertical planes. The lobes grow andshrink depending upon the ground plane effects and cancellation/additionof the radiating signal. Omnidirectional antennas are suitable for mostgeneral deployments.DirectionalRefers to the antenna coverage pattern. A directional antenna focuses itslobe or radiated energy in a particular direction. In general, as the gain of adirectional antenna increases, the radiating beamwidth or lobe decreases.This design increases the transmitted power and communication distancein a specific direction at the expense of uniform coverage, as comparedto an omnidirectional antenna. You must aim a directional antenna at theintended coverage zone.GainExpressed in dBi, indicates the relative increase in radiated power over anisotropic point radiating source with a reference gain of 1.0.Each 3 dB increment in power effectively doubles the radiated energy. Forexample, an antenna with a gain of 9 dBi increases the transmit power 8times more than an isotropic point radiating source. For example12.5 mW = 11 dBm11 dBm + 9dBi = 20 dBm20 dBm = 100 mW100mw/12.5 mW = 8 times more powerAvaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.
28 Common antenna terminologyE-Plane graphThe elevation plane graph shows the radiated antenna coverage patternas a vertical cross section — as if looking directly at the antenna from theside.H-Plane graphThe horizontal plane graph shows the radiated antenna coverage patternas a horizontal cross section — as if looking directly at the antenna fromabove.Avaya WLAN 8100Installation–AP 8120NN47251-302 01.AD 10 May 2010.
