\u00dcldine teave objekti ja serveri kohta<\/b><\/h3>\n

\nMeie ettev\u00f5te DATANETWORKS v\u00f5itis uue kolmekorruselise b\u00fcroohoone struktuurse kaabliv\u00f5rgu (SKV) rajamise tellimuse. V\u00f5rk sisaldab 321 porti, 14 patch-paneeli. Miinimumn\u00f5uded vaskkaabli ja komponentide puhul on cat 6a, FTP, kuna vastavalt uutele ISO 11801 standarditele peaks ettev\u00f5tte v\u00f5rgus kasutama v\u00e4hemalt 6. kategooria kaablit.<\/p>\n

Valik langes Corning tootevalikule. Valisime moodulid patch-paneelide jaoks, kuna neid on lihtsam hooldada ning \u00fche porta rikke korral saab selle h\u00f5lpsasti v\u00e4lja vahetada, kaotamata paneeli kasulikku ruumi. Kasutasime Corning sx500 mooduleid, varjestatud, cat 6a, Keystone paigaldust\u00fc\u00fcpi. Ostsime 42U CMS tootja kapp koos perforatsiooniga uste paremaks seadmete ventilatsiooniks ja suurendatud k\u00fclgruumiga kaabli paigalduse ja v\u00f5rgu seadmete paigaldamise optimeerimiseks. Tulevikus tuleb 800 mm laiusest kapp v\u00e4ga kasuks. Serveri kaablik\u00e4ik on ehitatud 300*50 mm v\u00f5rkkorvilt, toetudes mutritele ja klambritele.<\/p>\n

V\u00f5rgu rajamine kestis aasta jooksul, objekti erineva valmiduse t\u00f5ttu. Mina ja mu kolleeg k\u00e4isime paar korda aitamas kaabli k\u00e4igu ja kaabli venitamise seadistamisel, kuid peamise t\u00f6\u00f6 tegid teised paigaldajad. Meie t\u00f6\u00f6 viimaseks etapiks objektil oli kaabli paigaldamine ja \u00fchendamine kommunikatsioonikapis. Kogu protsess kestis viis p\u00e4eva, millest kolm p\u00fchendasime kaabli paigaldamisele korvitesse ja jaotamisele patch-paneelidele.<\/p>\n

\nServerisse sisenedes n\u00e4gime kolme kaabli sissetoomist, kaks tulid lae all olevast korvist ja \u00fcks p\u00f5randa alt kapi alla. Esialgu otsustasime l\u00fchendada liinid ligikaudu vajaliku pikkuseni, j\u00e4ttes mitu sentimeetrit varu \u00fchendamiseks ja m\u00e4rkimiseks. M\u00f5nede kaablite pikkus oli selgelt liiga suur, mis oleks takistanud edasist t\u00f6\u00f6d kaabli kammi ja korvi paigaldamisel. L\u00f5ikades liigse pikkuse, sorteerisime kaablid patch-paneelide j\u00e4rgi, 24 liini \u00fche paneeli jaoks ja iga pakendi \u201ekammisime\u201c PANDUIT'i kaabli paigaldusvahendi abil. M\u00f5eldes ette kaabli pakendite sissetoomise j\u00e4rjekorra peale kappi, kinnitasime need kaabli rihmadega, j\u00e4rgides iga 25-30 sentimeetri j\u00e4rel j\u00e4rjekorda. On soovitav eelnevalt aru saada paneelide asukohast ja paigaldada kaabel j\u00e4rjestikku, et v\u00e4ltida segadust. See protsess v\u00f5ttis meilt kaks p\u00e4eva, t\u00f6\u00f6 oli monotoonne, kuid tulemuseks on kaablik\u00e4ikude visuaalne ja tehniline korrastus. Kappi sissetoomisel otsustasime teha kaabli varu silmusena, et tagada edaspidine mugavus teenindusolukordades.<\/p>\n

Moodulite \u00fchendamine, patch-paneelide valimine ja paigaldamine kappi<\/b><\/h3>\n

\nKuna kaabel oli viidud patch-paneeli paigaldamise kohale, kinnitasime kaabli rihmadega liinid paneeli korraldusse vastavalt porta numbrile. Seej\u00e4rel l\u00f5ikasime veel kord liigse kaabli pikkuse, j\u00e4ttes paar sentimeetrit l\u00f5ikamiseks varuks.<\/p>\n

Oma praktika jooksul olen proovinud erinevaid mooduleid erinevatelt br\u00e4ndidelt. Pean \u00fctlema, et k\u00f5ige mugavam on Legrandi isekinnitusmoodul. Neil, kui p\u00f6\u00f6rata plastist nuppu, j\u00e4\u00e4b vastus osa kinnitatud ja tuleb ainult juhtmete otsad l\u00f5igata, kuid need komponendid on 5e UTP kategooriast, mis antud juhul meile ei sobi. Corningi moodul koosneb kahest osast ja vaskliimimisribast ekraani \u00fchendamiseks. Keerdpaaride v\u00e4rviskeem on h\u00e4sti kokku pandud ja v\u00e4hendab riski segadusse minna paaride l\u00f5ppude \u00fchendamisel. Testimisel osutus vigade osakaaliks alla 10%, mis 642 mooduli puhul, arvestades ekraani, on normaalne tulemus. \u00dchendamist\u00f6\u00f6d kestisid umbes 15 tundi, mina olin \u00fche racki k\u00fclje peal, partner teisel. Kogu selle aja pidin t\u00f6\u00f6tama seistes, mugavat t\u00f6\u00f6kohta ei olnud, sest racki tagaosa asus liiga l\u00e4hedal \u00fchenduskohale. Partner t\u00f6\u00f6tas istudes, tal vedas). Meie ametis tuleb tihti t\u00f6\u00f6tada ebamugavates tingimustes ja asendites. Vahel on palav, vahel k\u00fclm, kitsas, liiga k\u00f5rge v\u00f5i v\u00e4ga madal. Olen pidanud kaabli t\u00f5mbamiseks roomama v\u00f5i rippuma k\u00f5rgusel turvav\u00f6\u00f6 kinnitatud. Selle p\u00e4rast armastan oma t\u00f6\u00f6d, alati uusi asukohti, \u00fclesandeid ja lahendusi, mida tihti tuleb ise v\u00e4lja m\u00f5elda. B\u00fcroos istumine pole mulle kindlasti sobiv, p\u00e4rast 8 aastat selliseid seiklusi. Nii, kui 14 pat\u0161ipaneeli kokku monteeritud, on aeg k\u00f5ik kokku viia ja n\u00e4ha, milleks kulus viis p\u00e4eva. Kui paneelid ja kaabli korraldajad oma rakendustele kinni pandud (eelnevalt j\u00e4tan ruumi switchide paigaldamiseks) ja n\u00e4ed tulemust, saad tohutult rahulolu, seda v\u00f5iks nimetada euforiaks. Arvan, et tellija saab v\u00e4hem rahulolu kui mina, kui t\u00f6\u00f6 on tehtud korralikult. Vahel juhtub, et j\u00e4\u00e4b midagi ideaalset tegemata ja hiljem on raske magama j\u00e4\u00e4da, m\u00f5tled sellele, seet\u00f5ttu j\u00f5udsin j\u00e4reldusele, et parem on kohe h\u00e4sti teha. Loodan, et see on ka teie reegel t\u00f6\u00f6s!<\/p>\n

V\u00f5rgu testimine seadmega Fluke Networks DTX-1500<\/h3>\n

\nV\u00f5rgu terviklikkuse ja v\u00e4rvi pin-out'i testimist saab teha mitme seadmega. On lihtsaid testereid, millel on traadi ja v\u00e4rvikoosk\u00f5la testimise funktsioon, kuid v\u00f5rgu sertifitseerimise ja tootjani garantii saamiseks (antud juhul 20 aastat Corning'ilt) tuleb testida v\u00f5rku seadmega nagu DTX-1500 vastavalt rahvusvahelistele standarditele ISO v\u00f5i TIA. Seade peab kindlasti l\u00e4bima kalibreerimise kord aastas, mida me edukalt teeme, vastasel juhul pole tulemused kehtivad. Erinevalt tavalisest testerist, n\u00e4itab Fluke, millised paarid on segamini l\u00e4inud, samuti lingi pikkuse, signaali kadude ja palju muud teavet. Vea korral n\u00e4itab Fluke, millisel kaabli otsal probleem tekkis, mis oluliselt lihtsustab komponendi teenindamist. Seade ei ole odav, kuid suure SCS-i rajamiseks on see h\u00e4davajalik. P\u00e4rast testimise l\u00f5petamist saadetakse tulemused tootja hindamiseks ja kui k\u00f5ik on h\u00e4sti, annab ta garantii oma tootele.<\/p>\n

Testimise l\u00f5petamisel, k\u00f5ik vead parandades ja koristades, v\u00f5ib objekti montaa\u017eimeest pidada l\u00f5petatuks. Viiep\u00e4evane t\u00f6\u00f6reis on l\u00f5ppenud ja me s\u00f5idame rahulolevana koju. Edasi on projektijuhid ja projekteerijad, kelle \u00fclesanne on dokumentatsiooni esitamine.<\/p>\n

Autori kaudu:<\/i><\/b><\/p>\n

Soovin, et te saaksite nautida oma t\u00f6\u00f6d, h\u00e4sti tehtud projektidest. Minu jaoks on kohutav, kui t\u00f6\u00f6 on halvasti tehtud, m\u00f5tlen pidevalt sellele, ei saa rahu. Olen aru saanud, et on lihtsam kohe h\u00e4sti teha. Loodan, et see on ka teie reegel t\u00f6\u00f6s.
