Udinga i-UPS? Kuzobe kunani ukusekela kwebhethri okuvikela ikhompyutha yakho?
Ukusekelwa kwebhethri, noma ukunikezwa kwamandla okungenakuguqulwa (UPS) , kusetshenziselwa ngokuyinhloko ukuhlinzeka umthombo wamandla wokulondoloza kumakhi ebalulekile wekhompyutha yezingxenyekazi zekhompyutha .
Ezimweni eziningi, lezo zingcezu ze-hardware zihlanganisa izindlu ezinkulu zekhompiyutha kanye nokuqapha , kodwa amanye amadivaysi angangena kwi-UPS yamandla okusekela, kuye ngokuthi ubukhulu be-UPS.
Ngaphezu kokusebenza njenge-backup lapho amandla ephuma, amadivayisi amaningi okubheja amabhethri asebenza njengamandla "abakhumuzi" ngokuqinisekisa ukuthi ugesi ogeleza kwikhompyutha yakho nezesekeli akhululekile kumaconsi noma ukuqhuma. Uma ikhompyutha ingatholi ukugeleza kagesi okuqhubekayo, umonakalo ungakwazi futhi uvame ukwenzeka.
Ngenkathi uhlelo lwe-UPS aluyona ingxenye edingekayo yesistimu ephelele yekhompiyutha, kufaka phakathi eyodwa njengengxenye yakho okwenzelwe ngaso sonke isikhathi. Isidingo sokutholakala kagesi okunokwethenjelwa ngokuvamile kuvinjelwa.
Ukunikezwa kwamandla okungenakuphazamiseka, umthombo wamandla ongaqinisekisiwe, i-UPS ye-inthanethi, i-UPS yokulinda, ne-UPS ngamagama ahlukene ebhethri yebhethri.
Ungathenga i-UPS kusuka kubakhiqizi abathandwa njenge-APC, i-Belkin, i-CyberPower ne-Tripp Lite, phakathi kwamanye amaningi.
Izipele zebhethri: Okubukeka Kanjani & amp; Lapho Bahamba khona
Isipele sebhethri sihlezi phakathi kwamandla osizo (amandla avela ngaphandle kwendonga) kanye nezingxenye zekhompyutha. Ngamanye amazwi, ikhompyutha nezesekeli zixhuma kwisipele sebhethri kanye nama-plug-backup backup odongeni.
Amadivayisi we-UPS afika ezinhlotsheni eziningi namasayizi amaningi kodwa ajwayelekile kakhulu ama-rectangular and freestanding, ahloselwe ukuhlala phansi eduze kwekhompyutha. Zonke izipele zebhethri zinzima kakhulu ngenxa yamabhethri angaphakathi.
Ibhethri elilodwa noma ngaphezulu ngaphakathi kwe-UPS inikeza amandla kumadivaysi axhunyiwe kuwo lapho amandla avela kudoti odongeni engasatholakali. Amabhethri ayaphinda alayishwe futhi aphindaphindiwe, ahlinzeke isisombululo sesikhathi eside sokugcina uhlelo lwakho lwekhompiyutha lusebenza.
I-front of the backup ibhethri ngokuvamile izoba nomshini wokushintsha amandla ukuvula noma ukuvala idivayisi futhi ngezinye izikhathi ibe nezinkinobho ezengeziwe noma ngaphezulu ezenza imisebenzi ehlukahlukene. Amayunithi wokulondoloza amabhethri aphakeme kakhulu azophinde afake izikrini ze- LCD ezibonisa ulwazi mayelana nokuthi zithwalwe kanjani amabhethri, zingakanani amandla asetshenziswayo, njll.
Ingemuva ye-UPS izofaka eyodwa noma ngaphezulu izitolo ezinikezela isipele sebhethri. Ngaphezu kwalokho, amadivaysi amaningi okulondoloza ibhethri azophinde afake ukuvikeleka kokuqhutshwa kwamanye amazwe kwezinye izindawo futhi ngezinye izikhathi ngisho nokuvikelwa kokuxhumeka kwenethiwekhi, kanye nefoni kanye nemigqa yekhebula.
Amadivayisi wesipele sebhethri akhiqizwa ngezinga elihlukile lokukwazi ukusekela. Ukuze unqume ukuthi unamandla kangakanani we-UPS oyidingayo, okokuqala, sebenzisa i-EXtreme Power Supply Calculator ukubala izidingo ze-wattage yakho. Thatha le nombolo bese uyifaka kwizimfuneko zamattery kwamanye amadivaysi ongayifaka kwi-backup ibhethri. Thatha lenani elihlanganisiwe bese uhlola nomkhiqizi we-UPS ukuthola isikhathi sakho sokugijima kwebhethri uma ulahlekelwa amandla kusuka odongeni.
UPS on-Line vs UPS ngokuma
Kunezinhlobo ezimbili ezihlukene zama-UPS: I-UPS yokulinda uhlobo lokulondoloza ibhethri olufana nokunikezwa kwamandla okungaphazamiseki okungaxhunyiwe ku-intanethi kodwa alusebenzi ngokushesha.
Indlela osebenza ngayo i-UPS ngokuqapha amandla angena ekuhlinzekeni kokulondoloza ibhethri futhi angashintshi ibhethri aze athole inkinga (okungathatha ama-millisecond 10-12). I-UPS ye-inthanethi, ngakolunye uhlangothi, ihlala ihlinzeka amandla kwikhompyutha, okusho ukuthi inkinga itholakele noma cha, ibhethri ihlale ingumthombo wamandla wekhompiyutha.
Ungacabanga nge-UPS ye-inthanethi njengokungathi ibhethri ku-laptop. Ngenkathi i-laptop ixhunyiwe emgodini odongeni, ithola amandla njalo ngebhethri elithola amandla okuqhubekayo odongeni. Uma amandla okusodonga asuswe (njengokungathi ngesikhathi sokuphuma kwamandla), i-laptop iyakwazi ukuqhubeka inikwe amandla ngenxa yebhethri eyakhelwe ngaphakathi.
Umehluko wezwe wangempela-obala phakathi kwezinhlobo ezimbili zezinhlelo zokulondoloza ibhethri yilokho, uma inikezwa ibhethri inegunya elanele, ikhompyutha ngeke iguqulwe kusuka ekuphumeni kwamandla uma ixhunyiwe kwi-UPS ye-inthanethi, kodwa ingase ilahlekelwe amandla (ngisho noma imizuzwana embalwa kuphela) uma ifakwe ku-UPS yokulinda engaphenduli ngokuphuma ngokushesha ... nakuba izinhlelo ezintsha zingathola ukukhishwa kwamandla ngokushesha ku-2 ms.
Njengoba kunikezwe inzuzo echazwe nje, i-UPS e-inthanethi ngokuvamile ibiza ngaphezu kwe-UPS elayini.
Ulwazi Oluthe xaxa kuma-Backup Backup
Amanye amasistimu okulondoloza ibhethri owatholayo angabonakala engenangqondo ngoba ahlinzeka ngamaminithi ambalwa kuphela. Kodwa into okufanele ucatshangelwe yukuthi ngisho namaminithi angu-5 wamandla engeziwe, ungalondoloza ngokuphepha noma yimaphi amafayela avulekile futhi uvale ikhompyutha ukuvimbela umonakalo wehadiwe noma we-software.
Okunye okumele kukukhumbule ukuthi ukukhathazeka kangakanani kwikhompyutha yakho ukuvala ngokushesha lapho amandla evala ngisho namasekhondi ambalwa. Ngomshini oxhunywe kwi-UPS ye-intanethi, umcimbi onjalo ungase uphinde ungabonakali ngoba ibhethri izobe inikeza amandla ngaphambi, ngesikhathi, nangemva kokuphumula kwamandla.
Uma ngabe i-laptop yakho ike yalala noma ivalwe kuwe ngemuva kokuyeka ukuyisebenzisa okwesikhashana, kodwa kuphela uma ingaxhunyiwe, uyazi ukuthi amadivaysi anikwe amandla asebhethri angaziphatha ngendlela ehlukile kunezidakamizwa. Lokhu kungenxa yokukhethwa kwamandla okwakhiwe ngaphakathi ohlelweni lokusebenza .
Ungasetha into efanayo ekhompyutheni yedeskithophu esebenzisa i-UPS (uma i-UPS ikwazi ukuxhuma nge- USB ) ukuze ikhompiyutha ingene kumodi ye-hibernation noma ivale ngokuphepha uma ishintshela amandla emthamo ngesikhathi sokuphuma.
