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 igcinelwe 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:
