Chaper Planning Repeaer Insallaion This chaper conains informaion ha will help you prepare for insalling he Micro 00-TX4 repeaer. This includes insallaion requiremens and sysem planning chars. Insallaion Requiremens To help ensure a correc insallaion, read his secion o deermine he environmenal, elecrical, spaial, and cable requiremens. Environmenal Requiremens Be sure he operaing environmen for he repeaer is wihin he following ranges: Temperaure: 3º o ºF (0º o 50ºC) Humidiy: 5% o 95% (non-condensing) Aliude: 0 o 0,000 fee (0 o 3 km) Clearance: minimum of inches (5. cenimeers) on each side of he repeaer for proper venilaion Elecrical Requiremens The elecrical requiremens for a Micro 00-TX4 repeaer are as follows: 00 40 VAC.5 0.75 Amps (.5A @ 00 VAC 0.75A @ 40 VAC) 50 60 Hz Cauion: The power oule mus be a non-swiched, hree-pronged, grounded oule. Do no use a hree-o-wo pronged adaper a he oule. Doing so may resul in elecrical shock and/or damage o he repeaer and will void your warrany. Noe: If he supplied power cord is los or damaged, replace i wih a power cord of he same ype and curren raing (0A). The replacemen cord should also mee required regulaory approvals o ensure emissions compliance. -
Insallaion Requiremens Planning Repeaer Insallaion Spaial Requiremens The Micro 00-TX4 repeaer s dimensions are 3 inches (heigh) x 6.95 inches (widh) x 4 inches (deph). You can inerconnec wo Micro 00-TX4 repeaers. If here is no enough space o moun he repeaers in a single rack or sack hem on a single shelf, or if you wan o place he repeaers in differen locaions, you can place hem side by side on separae shelves or in separae racks. See Twised-Pair (UTP) Wire Requiremens for more informaion. Be sure o allow a leas inches (5. cenimeers) on each side of he repeaer for proper air circulaion and cable connecions. Twised-Pair (UTP) Wire Requiremens The wised-pair wiring you use o connec he repeaer s RJ-45 pors mus mee he following minimum specificaions and requiremens o ensure long-erm reliabiliy. The wiring mus be unshielded wised-pair (UTP) Caegory 5. Two pairs of he four-pair wiring are used for signalling. Depending on building codes, differen insulaion maerials may be required. Plenum-raed or TEFLON -coaed wiring may be required in some areas. The wire gauge should be beween 8 and 6 AWG. (Mos elephone insallaions use 4-gauge wiring.) Solid copper Insalling New Wire If you are insalling he repeaer where no wiring is presen, or if exising wiring does no mee he above specificaions, insall new wiring. The new wiring should conform o naional and local elecrical wiring code requiremens and mee he above specificaions. When insalling wire, i is a good idea o insall exra pairs of wire for fuure expansion. If you are unfamiliar wih wiring insallaion or he applicable local elecrical wiring code or he 00BASE-TX specificaion, you should have a professional, licensed (if applicable) insaller perform he insallaion. -

MACs ha are separaed by a bridge are wihin differen collision domains. Daa Terminal Equipmen. A DTE can be a source or desinaion communicaions device (ypically a compuer) ha sends or receives nework ransmissions. Elecronic Indusries Associaion. The EIA is an organizaion ha ses elecrical and elecronic inerface sandards. The abiliy of a device (such as a redundan power supply) o be added o or removed from a hub wihou powering down he hub. A device used o provide conneciviy beween DTEs. Hubs perform basic funcions such as resoraion of signal ampliude and iming, collision deecion and noificaion, and signal broadcas o lower level hubs and DTEs. Inernaional Elecroechnical Commission. The IEC, an organizaion comprised of commiees from several differen counries, ses inernaional elecrical and elecronic sandards. Insiue of Elecrical and Elecronic Engineers. The IEEE, a membership organizaion made up of people in elecronics relaed fields, is involved wih seing sandards for communicaions and compuers. Glossary -

A mechanism for connecing wo and only wo repeaer ses. A delay or ime gap beween CSMA/CD packes inended o provide inerface recovery ime for oher CSMA/CD sublayers and for he Physical Medium. For 0BASE-T, he IPG is 9.6 us (96 bi imes). For 00BASE-T, he IPG is 0.96 us (96 bi imes). Coninuous ransmission from a node, generally as a resul of a hardware or firmware failure. A mechanism for conrolling abnormally long ransmissions. The lengh of ime from he poin a which he firs bi of a packe eners a por o he poin a which he firs bi of he packe exis anoher por. Ligh Emiing Diode, ypically used o indicae he operaing saus of a hub or module. A communicaion mechanism used in 0BASE-T neworks o indicae link saus and, in auo-negoiaion equipped devices, o communicae informaion abou abiliies and negoiae communicaion mehods. 0BASE-T uses Normal Link Pulses (NLPs) which indicae link saus only. 0BASE-T and 00BASE-T nodes equipped wih auo-negoiaion exchange informaion using a Fas Link Pulse (FLP) mechanism which is compaible wih NLP. Media Access Conroller A module is manageable if i conains an SNMP agen and here is a daa communicaion pah o ha agen from an SNMP manager. A ransparen signal inerface beween he MAC or repeaer and he media ransceiver device. Nework Inerface Card. A NIC is a plug-in expansion board ha enables nodes o send and receive daa over he nework. The elecrical disconnecing of a node from a LAN a is poin of connecion o a hub. The node remains physically aached. A node can be auopariioned by he hardware when 30 consecuive frame errors occur. The recepion of one good frame re-enables he auopariioned por. A Proocol Daa Uni (PDU) is a packe ha conains conrol informaion and opional daa. An exernal connecor used o connec PCs and oher node devices o he nework. A device ha amplifies a signal a regular inervals in a communicaions circui. A repeaer uni plus is associaed physical layer inerfaces (MAUs or PHYs). Glossary -
Glossary RJ-45 Segmen Sack Twised Pair Wire Uplink UTP Wiring Environmen Wiring Close An 8-wire modular connecor used for 0BASE-T Eherne, 00BASE-T Eherne, and some elephones. A single collision domain. Each Fas Eherne segmen suppors a 00 Mbps bandwidh. A muliple segmen implemenaion increases he bandwidh of a Local Area Nework. A sack is a group of inerconneced hubs. Two insulaed copper wires wised ogeher. The wiss vary in lengh o reduce he poenial for signal inerference beween pairs. In cables greaer han 5 pairs, he wised pairs are grouped and bound ogeher in a common cable sheah. Twised pair cable is he mos common ype of ransmission media. The connecion from one hub o anoher, usually done o expand a nework segmen. Unshielded Twised Pair cable is usually conneced using RJ-45 connecors. Any building communicaions wiring sysem. A room, close or cabine where saion cable is erminaed on crossconnec blocks and where he building communicaions sysem can be adminisered. Glossary - 3
