Njengoba imishini ye-IT iba mincane kakhulu, ihlanganiswe kahle kakhulu, futhiesekelwe ku-rack, igumbi lekhompyutha, "inhliziyo" yesikhungo sedatha, liveze izidingo ezintsha nezinselele zokwakhiwa nokuphathwa kwalo. Indlela yokunikeza indawo yokusebenza ethembekile yemishini ye-IT ukuqinisekisa ukunikezwa kwamandla okungenakugwenywa kanye nezidingo zokushabalalisa ukushisa okuphezulu sekuyinto ebalulekile ekunakweni okwandayo kwabasebenzisi abaningi.
Ikhabhinethi yokuxhumana yangaphandleuhlobo lwekhabhinethi yangaphandle. Libhekisela kukhabhinethi ethonywe ngqo isimo sezulu semvelo futhi eyenziwe ngezinto zensimbi noma ezingezona ezensimbi. Abasebenzi abangagunyaziwe abavunyelwe ukungena nokusebenza. Lihlinzekwa kumasayithi okuxhumana angenantambo noma ezindaweni zokusebenza zenethiwekhi enezintambo. Imishini yezindawo zokusebenza zangaphandle kanye nezinhlelo zokuphepha.
Emcabangweni wendabuko, incazelo yendabuko yabasebenzi bamakhabethe egumbini lekhompyutha lesikhungo sedatha ithi: ikhabethe limane nje liyisithwali semishini yenethiwekhi, amaseva kanye neminye imishini egumbini lekhompyutha lesikhungo sedatha. Ngakho-ke, ngokuthuthukiswa kwezikhungo zedatha, ingabe ukusetshenziswa kwamakhabethe emakamelweni ekhompyutha esikhungo sedatha kuyashintsha? Yebo. Abanye abakhiqizi abagxile emikhiqizweni yegumbi lekhompyutha banikeze amakhabethe imisebenzi eminingi ngenxa yesimo samanje sokuthuthukiswa kwamakamelo ekhompyutha esikhungo sedatha.
1. Thuthukisa ubuhle begumbi lekhompyutha ngokubukeka okuhlukahlukene
Ngaphansi kwendinganiso esekelwe kububanzi bokufakwa kwemishini obuyi-intshi ezingu-19, abakhiqizi abaningi basungule ukubukeka kwamakhabethe futhi benza imiklamo emisha ehlukahlukene bebheka ukubukeka kwamakhabethe ezindaweni ezilodwa neziningi.
2. Qaphela ukuphathwa okuhlakaniphile kwamakhabhinethi
Kumakamelo ekhompyutha esikhungo sedatha anezidingo eziphezulu zendawo yokusebenza kanye nokuphepha kwamakhabethe, kunesidingo esikhulayo samakhabethe esistimu ahlakaniphile ukuhlangabezana nezidingo ezifanele. Ubuhlakani obuyinhloko bubonakala ekwahlukaneni kwemisebenzi yokuqapha:
(1) Umsebenzi wokuqapha izinga lokushisa nomswakama
Uhlelo lwekhabhinethi oluhlakaniphile luhlonyiswe ngedivayisi yokuthola izinga lokushisa nomswakama, engaqapha ngobuhlakani izinga lokushisa nomswakama wendawo yangaphakathi yesistimu yokuphakelwa kwamandla elawulwayo, futhi ibonise amazinga okushisa nomswakama aqashwe esikrinini sokuthinta sokuqapha ngesikhathi sangempela.
(2) Umsebenzi wokuthola intuthu
Ngokufaka izitholi zomusi ngaphakathi kohlelo lwekhabhinethi ehlakaniphile, isimo somlilo sohlelo lwekhabhinethi ehlakaniphile siyatholwa. Uma kwenzeka okungajwayelekile ngaphakathi kohlelo lwekhabhinethi ehlakaniphile, isimo se-alamu esifanele singaboniswa esibonakalayo sokubonisa.
(3) Umsebenzi wokupholisa ohlakaniphile
Abasebenzisi bangasetha isethi yamazinga okushisa ohlelweni lokuphakelwa kwamandla olulawulwayo ngokusekelwe endaweni yokushisa edingekayo lapho imishini ekhabetheni isebenza. Lapho izinga lokushisa ohlelweni lokuphakelwa kwamandla olulawulwayo lidlula leli banga, iyunithi yokupholisa izoqala ukusebenza ngokuzenzakalelayo.
(4) Umsebenzi wokuthola isimo sesistimu
Uhlelo lwekhabhinethi oluhlakaniphile ngokwalo lunezinkomba ze-LED zokubonisa isimo salo sokusebenza kanye nama-alamu okuqoqwa kolwazi lwedatha, futhi lungaboniswa ngokwemvelo esikrinini sokuthinta se-LCD. I-interface iyinhle, ivulekile futhi icacile.
(5) Umsebenzi wokufinyelela idivayisi ehlakaniphile
Uhlelo lwekhabhinethi ehlakaniphile lunokufinyelela kumadivayisi ahlakaniphile kufaka phakathi amamitha kagesi ahlakaniphile noma izinsiza zikagesi ezingenakunqandeka ze-UPS. Lufunda amapharamitha edatha ahambisanayo ngokusebenzisa isikhombikubona sokuxhumana se-RS485/RS232 kanye nephrothokholi yokuxhumana ye-Modbus, futhi luwabonisa esikrinini ngesikhathi sangempela.
(6) Umsebenzi wokukhipha oguqukayo we-Relay
Uma uhlelo lwekhabhinethi ehlakaniphile luxhumanisa i-logic yesistimu eklanywe kusengaphambili, umlayezo ovame ukuvuleka/uvame ukuvalwa uzothunyelwa esiteshini se-DO se-hardware interface ukuze kushayelwe imishini exhunywe kuyo, njenge-alamu ezwakalayo nebonakalayo, amafeni, njll. kanye neminye imishini.
Ake sifingqe ezinye zezinkinga mayelanaikhabhinethiusayizi wakho. U iyunithi emele ubukhulu bangaphandle beseva futhi iyisifinyezo seyunithi. Ubukhulu obunemininingwane bunqunywa yi-Electronic Industries Association (EIA), iqembu lemboni.
Isizathu sokucacisa usayizi weseva ukugcina usayizi ofanele weseva ukuze ibekwe phezu kwerakhi yensimbi noma ye-aluminium. Kunezimbobo zezikulufo zokubopha iseva ku-rakhi ukuze ivumelane nezimbobo zezikulufo zeseva, bese iqiniswa ngezikulufo ukuze kube lula ukufakwa kweseva ngayinye endaweni edingekayo.
Ubukhulu obucacisiwe ububanzi beseva (48.26cm = 19 amayintshi) kanye nokuphakama (okuphindaphindwayo okungu-4.445cm). Ngenxa yokuthi ububanzi bungama-intshi angu-19, i-rack ehlangabezana nale mfuneko ngezinye izikhathi ibizwa ngokuthi "Irekhi engamasentimitha angu-19." Iyunithi eyisisekelo yobukhulu ingu-4.445cm, kanti i-1U ingu-4.445cm. Bheka ithebula elingezansi ukuthola imininingwane: Ukubukeka kwekhabhinethi ejwayelekile engu-19 intshi inezinkomba ezintathu ezivamile: ububanzi, ukuphakama, kanye nokujula. Nakuba ububanzi bokufakwa kwemishini yephaneli engu-19 intshi ingu-465.1mm, ububanzi obuvamile bamakhabhinethi bungu-600mm no-800mm. Ukuphakama ngokuvamile kusuka ku-0.7M-2.4M, kanti ukuphakama okuvamile kwamakhabhinethi aqediwe angu-19 intshi kungu-1.6M no-2M.
Ukujula kwekhabhinethi ngokuvamile kusuka ku-450mm kuya ku-1000mm, kuye ngobukhulu bemishini ekhabhinethi. Ngokuvamile abakhiqizi bangenza ngezifiso imikhiqizo ngokujula okukhethekile. Ukujula okuvamile kwamakhabhinethi aqediwe angama-intshi angu-19 yi-450mm, 600mm, 800mm, 900mm, kanye ne-1000mm. Ukuphakama okuhlala imishini efakwe kukhabhinethi ejwayelekile engama-intshi angu-19 kumelelwa yiyunithi ekhethekile ethi "U", 1U=44.45mm. Amaphaneli emishini asebenzisa amakhabhinethi ajwayelekile angama-intshi angu-19 ngokuvamile akhiqizwa ngokwezincazelo ze-nU. Kweminye imishini engeyona ejwayelekile, iningi lawo lingafakwa ku-chassis engama-intshi angu-19 ngokusebenzisa ama-baffle engeziwe e-adaptha futhi alungiswe. Imishini eminingi yezinga lobunjiniyela inobubanzi bamaphaneli obungama-intshi angu-19, ngakho-ke amakhabhinethi angama-intshi angu-19 yiwona ikhabhinethi ejwayelekile evame kakhulu.
I-42U ibhekisela ekuphakameni, 1U=44.45mm. AIkhabhinethi engu-42uayikwazi ukubamba amaseva angu-42 e-1U. Ngokuvamile, kuvamile ukubeka amaseva angu-10-20 ngoba adinga ukubekwa ngesikhala ukuze kuqedwe ukushisa.
Amasentimitha angu-19 ububanzi bungu-482.6mm (kukhona "izindlebe" ezinhlangothini zombili zedivayisi, kanti ibanga lokufaka imbobo yezindlebe lingu-465mm). Ukujula kwedivayisi kuhlukile. Izinga likazwelonke alichazi ukuthi ukujula kumele kube yini, ngakho ukujula kwedivayisi kunqunywa umenzi wedivayisi. Ngakho-ke, ayikho ikhabethe le-1U, imishini ye-1U kuphela, futhi amakhabethe asukela ku-4U kuya ku-47U. Okusho ukuthi, ikhabethe le-42U lingafaka ngokombono imishini ephezulu ye-42 1U, kodwa empeleni, ngokuvamile iqukethe amadivayisi ayi-10-20. Okuvamile, ngoba adinga ukuhlukaniswa ukuze kuqedwe ukushisa.
