Ama-PDU (Amayunithi Okusabalalisa Amandla) angamadivayisi asabalalisa amandla kagesi kumadivayisi amaningi ngaphakathi kwesikhungo sedatha noma igumbi leseva. Nakuba ama-PDU ngokuvamile ethembekile, angathola izinkinga ezivamile. Nazi ezimbalwa zazo namathiphu angakusiza ukuthi uwagweme:
1，Ukulayishwa ngokweqile: Ukulayishwa ngokweqile kwenzeka lapho inani lamandla eliphelele lamadivayisi axhunyiwe lidlula umthamo olinganiselwe we-PDU. Lokhu kungaholela ekushiseni ngokweqile, kuma-circuit breaker, noma ngisho nasezingozini zomlilo. Ukuze ugweme ukugcwala ngokweqile, cabanga ngalokhu okulandelayo:
*Nquma izidingo zamandla zamadivayisi akho futhi uqinisekise ukuthi aweqeli umthamo we-PDU.
*Sabalalisa umthwalo ngokulinganayo kuma-PDU amaningi uma kunesidingo.
*Qapha njalo ukusetshenziswa kwamandla futhi wenze izinguquko njengoba kudingeka.
Uma wenza ngendlela oyifisayo i-PDU yakho, ungafaka isivikeli esilayisha kakhulu ku-PDU, njenge-NewsunnIyunithi Yokusabalalisa Amandla Ohlobo lwesiJalimane enomvikeli ogcwele ngokweqile.
I-2, Ukuphathwa Kwekhebula Okungalungile: Ukuphathwa kwekhebula okungalungile kungaholela ekucindezelekeni kwekhebula, ukunqanyulwa ngengozi, noma ukugeleza komoya okuvinjiwe, okungabangela ukuphazamiseka kwamandla noma ukwehluleka kwemishini. Ukuze uvimbele izinkinga ezihlobene nekhebula:
* Hlela futhi ulebule izintambo ngendlela efanele ukuze unciphise ubunzima futhi wenze kube lula ukuxazulula inkinga.
* Sebenzisa izesekeli zokuphatha ikhebula njengezintambo zekhebula, ama-rack, namashaneli ekhebula ukuze ulondoloze ukusethwa kahle nokuhlelekile.
* Hlola njalo futhi ugcine ukuxhunywa kwamakhebula ukuze uqinisekise ukuthi avikelekile.
I-3, Izinto Zemvelo: Ama-PDU angathinteka yizimo zemvelo ezifana nezinga lokushisa, umswakama, nothuli. Amazinga okushisa aphakeme noma amazinga omswakamo aphezulu angalimaza izingxenye ze-PDU noma aholele ekungasebenzini kahle. Ukunciphisa lezi zici:
* Qinisekisa ukuthi isikhungo sedatha noma igumbi leseva linezinhlelo ezifanele zokupholisa kanye nokukhipha umoya endaweni.
* Qaphela futhi ugcine izinga lokushisa kanye nomswakama ngaphakathi kwebanga elinconywayo.
* Hlanza njalo i-PDU nezindawo ezizungezile ukuze uvimbele ukunqwabelana kothuli.
I-4, Ukuntuleka Kwe-Redundancy: Amaphuzu awodwa okwehluleka angaba inkinga ebalulekile uma i-PDU yehluleka. Ukuze ugweme lokhu:
* Cabangela ukusebenzisa ama-PDU angafuneki noma okuphakelayo kwamandla akabili kumishini ebalulekile.
* Sebenzisa amasistimu e-failover azenzakalelayo noma imithombo yamandla eyisipele njenge-UPS (Uninterruptible Power Supply).
5, Izinkinga Ezivumelanayo: Qinisekisa ukuthi i-PDU iyahambisana nezidingo zamandla nezixhumi zamadivayisi akho. I-voltage engafani, izinhlobo zesokhethi, noma izitolo ezinganele zingabangela izinkinga zokuxhuma. Buyekeza ukucaciswa futhi uxhumane nochwepheshe uma kudingeka.
6, Ukuntuleka Kokuqapha: Ngaphandle kokuqapha okufanele, kuyinselele ukuhlonza izinkinga ezingaba khona noma ukulandelela amaphethini okusetshenziswa kwamandla. Ukubhekana nalokhu:
* Sebenzisa ama-PDU anamakhono okuqapha akhelwe ngaphakathi noma cabanga ukusebenzisa amadivayisi okuqapha amandla.
* Sebenzisa isoftware yokuphatha amandla ekuvumela ukuthi ugade, uphathe, futhi ulandelele ukusetshenziswa kwamandla, izinga lokushisa, namanye amamethrikhi.
* I-PDU Eqashiwe iya idume kakhulu ezikhungweni zedatha. Ungakwazi ukuqapha isamba se-PDU noma isitolo ngasinye ukude, futhi uthathe izilinganiso ezifanele. I-Newsunn inikezela nge-OEM yeI-PDU ihlolwe.
Ukunakekelwa okuvamile, ukuhlolwa, nokuqapha okuqinile kubalulekile ekuhlonzeni nasekuxazululeni izinkinga ezingaba khona ngama-PDU. Ukwengeza, kuyanconywa ukuthi uthintane nezinkombandlela zomkhiqizi kanye nezinqubo ezihamba phambili zomkhakha zamamodeli athile we-PDU nokulungiselelwa.
