Ukukhetha isikhathi sokuhlela

Kumabhidi amaningi esikhungo sedatha, ayibonisi i-PDU njengohlu oluhlukile oluhlangene ne-UPS, amakhabethe ahlukahlukene, ama-racks nezinye izinto zokusebenza, kanye nemingcele ye-PDU ayicacile kahle. Lokhu kuzodala inkinga enkulu emsebenzini wakamuva: kungase kungafani nezinye izinto zokusebenza, ukusatshalaliswa okungajwayelekile, ukushoda okukhulu kwesabelomali, njll. Isizathu esiyinhloko salesi simo ukuthi zombili izinhlangothi azicaci ukuthi zilebula kanjani izidingo ze-PDU. Nansi indlela elula yokwenza.

1) Amandla wesifunda segatsha kukhabhinethi yamalungu afanayo + umkhawulo wokuphepha = amandla aphelele ama-PDU kulo mugqa.

2) Inombolo Yezisetshenziswa ku-rack+ yokuphepha yemajini = inani lezitolo kuwo wonke ama-PDU endaweni yokubeka. Uma kunemigqa emibili engasasebenzi, inombolo ye-PDU kufanele iphindwe kabili ngepharamitha.

3) Izinto ezisetshenziswa amandla aphezulu kufanele zihlakazwe kuma-PDU ahlukene ukuze kulinganiswe ukusebenza kwesigaba ngasinye.

4) Enza ngendlela oyifisayo izinhlobo ze-PDU zokuphuma ngokuya ngalawo mapulaki asetshenziswayo angakwazi ukuhlukaniswa nentambo yamandla. Uma ipulaki engahlukaniswa nentambo yamandla ingahambisani, ingaxazululwa ngokufaka esikhundleni sentambo yamandla.

5) Lapho ukuminyana kwemishini kuphezulu ekhabetheni, kungcono ukhethe ukufakwa okuqondile; kuyilapho uma ukuminyana kwemishini kuphansi, kungcono ukhethe ukufakwa okuvundlile. Okokugcina, i-PDU kufanele inikezwe isabelomali sekhotheshini esihlukile ukugwema ukushoda okukhulu kwesabelomali.

Ukufakwa kanye nokulungisa iphutha

I-1) Amandla ekhabhinethi kufanele afane namandla wesifunda segatsha kukhabhinethi ye-array kanye namandla e-PDU, ngaphandle kwalokho kuzonciphisa ukusetshenziswa kwenkomba yamandla.

2) Indawo ye-U ye-PDU kufanele ibekelwe ukufakwa kwe-PDU evundlile, kuyilapho ukufakwa kwe-PDU eqondile kufanele unake i-engeli yokukhweza.

Isikhathi sokusebenza

1. Naka inkomba yokwenyuka kwezinga lokushisa, okungukuthi, ukushintsha kwezinga lokushisa kwepulaki yedivayisi namasokhethi e-PDU.

2. Nge-PDU yokuqapha ekude, unganaka izinguquko zamanje ukuze unqume ukuthi okokusebenza kusebenza kahle yini.

3. Sebenzisa ngokugcwele idivayisi ye-PDU yokufaka izintambo ukuze ubolise amandla angaphandle epulaki yedivayisi kumasokhethi e-PDU.

Ubudlelwano phakathi kwefomu lezitolo ze-PDU namandla alinganiselwe e-PDU

Uma usebenzisa i-PDU, sihlangabezana nezimo lapho ipulaki yedivayisi ingafani namasokhethi e-PDU. Ngakho-ke, lapho senza ngokwezifiso i-PDU, kufanele siqale siqinisekise ifomu lepulaki lemishini namandla emishini, siphethe i-oda ngokulandelayo:

Amandla esokhethi okukhiphayo e-PDU = amandla epulaki edivayisi ≥ amandla edivayisi.

Ubudlelwano obuhambisanayo phakathi kwepulaki namasokhethi e-PDU bumi kanje:
