Ungakhetha kanjani i-PDU?

Inani lemali

1) Umdidiyeli: ujwayelene nezisetshenziswa ezisegumbini lekhompiyutha, ukufanisa okuphelele, ukulungiswa okuphelele, kanye nenani eliphezulu.

2) Abakhiqizi bemishini: Ingakwazi ukufanisa ngokunembile ifomu le-jack kanye nemingcele yamandla ngokuthengiswa kwemishini efana namaseva, ama-routers, amaswishi, njll., kanye nephakheji futhi ixazulule nemishini, futhi intengo iphakathi.

3) Ifekthri yeKhabhinethi: Ifekthri yekhabhinethi iyimboni yensimbi, futhi ayinazo iziqu zokukhiqiza izinto zikagesi, ikakhulukazi i-OEM yefekthri yekhabhinethi.Ukulawulwa kwekhwalithi kanye nezinguquko zomkhiqizo zimbi, intengo iyadida, izinhlanzi nezinhlanzi zixutshwe, futhi kunzima ukuzibona, kodwa ukufakwa Kwezinto Ezilula.Pakisha futhi uhlale nekhabhinethi.

I-4) Abahlinzeki bamandla kagesi abaqeqeshiwe: njengamakhabethe okusabalalisa amandla ekhanda lekholomu kanye nabathengisi abangochwepheshe be-PDU, ungathola isiqondiso sochwepheshe nosizo, ukwenza ngokwezifiso okuguquguqukayo, ukumisa okujwayelekile, ukuphepha okuphezulu, kanye nenani eliphansi, kudinga nje ukuxazululwa ngokuhlukana.

5) Imikhiqizo yasekhaya neyangaphandle: isitifiketi somkhiqizo wangaphandle siphelele, ukuqinisekiswa kwekhwalithi;kodwa intengo iphakeme, isikhathi sokulethwa side, ngokuvamile sithatha amasonto angu-6-8, ifomu lesokhethi lilodwa, futhi ukuhambisana nepulaki yemishini kubi, kuwumkhiqizo oyimodeli evamile, futhi ayikwazi ukwenziwa ngezifiso.;Ukuqinisekisa okuphelele kwezingxenye zomkhiqizo wasekhaya wezinga eliphezulu, iziqu zefekthri eziphelele, ukuhlolwa komkhiqizo owodwa, intengo emaphakathi (elingana no-1/3~1/2 wemikhiqizo yamazwe ngamazwe), isevisi ephelele, nezinga eliphezulu lokwenza ngokwezifiso imikhiqizo;kuyilapho amabhrendi asekhaya asezingeni eliphansi : Ukuqinisekiswa kwezingxenye akuphelele futhi ukuzinza kwekhwalithi akuphezulu.Iningi lazo yimikhiqizo ehlanganiswe izimboni ezincane zokuqagela.Imboni ayinazo iziqu noma isebenzisa iziqu zabanye.Amapharamitha anesiphithiphithi futhi ukuziphatha kunesibindi.Okunye kungenziwa ngokwezifiso, futhi intengo iphansi kakhulu.Esikhundleni sokusebenzisa le PDU, kungcono ukusebenzisa umugqa wamandla womkhiqizo ophezulu oyiqiniso.

Ukuhlela nokukhetha

Emabhideni amaningi egumbi lamakhompiyutha, i-PDU ayibalwa njengomugqa ohlukile njenge-UPS, ikhabethe lekhanda lekholomu, iKhabhinethi nezinye izinto zokusebenza, kanye nemingcele edingekayo ye-PDU nayo ayicacile kahle, futhi eminye ikhombisa nje umugqa wamandla, okuzodala okukhulu. inkinga emsebenzini wakamuva.: Okusho ukuthi, ukungakwazi ukuhambisana nezinye izinto zokusebenza, ukunikezwa kwamandla okungajwayelekile, ukushoda okukhulu kwesabelomali, njll. Isizathu esiyinhloko salesi simo ukuthi zombili izinhlangothi ekubhideni nasekufakeni amathenda akucaci ukuthi imaka kanjani i-PDU edingekayo?Nansi indlela elula kuwe:

I-1) Amandla wesifunda wegatsha lokusabalalisa lekhabhinethi yekhanda lekholomu + umkhawulo wokuphepha = isamba samandla ama-PDU kulo mugqa;

2) Inani lamadivayisi kukhabhinethi + imajini yokuphepha = inani lamajack awo wonke ama-PDU kukhabhinethi.Uma kunemigqa emibili engasasebenzi, inani lama-PDU kufanele liphindwe kabili ngokuya ngamapharamitha.

3) Ukusabalalisa imishini yamandla aphezulu kuma-PDU ahlukene ngangokunokwenzeka ukuze ulinganise amandla amanje esigaba ngasinye;

4) Iphethini yembobo ye-PDU yenziwe ngendlela oyifisayo ngokusekelwe kumapulaki edivayisi izintambo zawo zamandla azikwazi ukuhlukaniswa.Uma izixhumi zedivayisi izintambo zamandla zazo zingahlukaniswa zingahambelani, intambo yamandla ingashintshwa ukuze kuxazululwe inkinga;

I-5) Uma ukuminyana kwemishini ekhabhinethi kuphezulu, i-PDU kufanele ifakwe ngokuqondile ngama-jack amaningi.Uma ukuminyana kwemishini kukhabhinethi kuphansi, i-PDU kufanele ifakwe ivundlile ngojeke abambalwa.Okokugcina, isabelomali sekhotheshini esehlukile kufanele sinikezwe i-PDU ukugwema ukushoda okukhulu kwesabelomali.

Izindawo zokuthenga

1) Khetha umkhiqizo ofanelana nawe ngokwesimo sakho esithile;

2) Khetha imikhiqizo evela kubakhiqizi abajwayelekile (yebo, abanye abakhiqizi bangase babe abakhiqizi abavamile, kodwa i-PDU ingase ingabi umkhiqizo wabo ovelele, ngakho kufanele uqaphele lapho ukhetha. Nakuba udokotela wezilwane engudokotela, awukwazi ukucabanga ukuthi isikhathi eside. njengoba engudokotela, futhi ungudokotela odumile.

3) Umbuso unokuhlolwa kwekhwalithi efanele kanye nesitifiketi semikhiqizo ehlukahlukene.Lapho ukhetha imikhiqizo ye-PDU, kufanele uqale ubheke iziqu zomenzi, bese ubheka ukuqinisekiswa kwekhwalithi yomkhiqizo.Kuphephile ukukhetha imikhiqizo ejwayelekile;

4) Ngemva kokufingqa lokhu okungenhla, bese uqonda insizakalo yangemva kokuthengisa yemikhiqizo ehlobene (noma ngabe muhle kangakanani umkhiqizo, akekho ongaqinisekisa ukuthi ngeke wephulwe, ngakho-ke isevisi yangemva kokuthengisa nayo iyinkinga eyinhloko; futhi khumbula ukuthi insizakalo yangemva kokuthengisa ayikwazi ukushiwo ngegama kuphela, kunconyelwa ukumila izimpande. , ibeke ngamagama);

5) Lapho ukhetha i-PDU, kufanele uqale ubheke iziqu zomkhiqizi kanye nemibhalo yesitifiketi sasefekthri ukuze uqinisekise ukwethembeka kokucubungula;okwesibili, bheka iziqu zomkhiqizo, imibhalo yokuhlola, imanyuwali yemikhiqizo, amapuleti okuhlonza, njll. ukuze uqinisekise umkhiqizo.evamile.I-PDU iwumkhiqizo owenziwe ngezifiso ozinikezele ekusabalaliseni amandla egumbini lekhompyutha.Inani lesipiliyoni sokufanisa ukusetshenziswa kwamandla kwemishini egumbini lekhompyutha libaluleke kakhulu.Ngakho-ke, isipiliyoni somkhiqizi siyinkomba ebalulekile yokuhlola ukuzinza nobuchwepheshe bomkhiqizo we-PDU.Isiqondiso sangaphambi kokuthengisa: Ukuthi kukhona yini ukuqondiswa kokuthengiswa kwangaphambili kuwuphawu olubalulekile lokuthi umkhiqizi we-PDU uchwepheshe noma cha.Uma ungenaso isiqondiso sochwepheshe lapho ukhetha futhi wenza ngendlela oyifisayo, uzokhokha izindleko ezibuhlungu ngokuhamba kwesikhathi: okokusebenza ngeke kukwazi ukusebenzisa ugesi, ukufanisa amandla akonele, indawo ephansi iphansi, ngisho nemishini eshisiwe kanye nokuphazamiseka kwentambo kagesi kuzolandela. isudi.
