Ukhetho lwexesha lokucwangcisa

Kwiibhidi ezininzi zamaziko edatha, ayibonisi i-PDU njengoluhlu olwahlukileyo kunye ne-UPS, iikhabhathi zoluhlu, iiracks kunye nezinye izixhobo, kunye neeparamitha zePDU azicacanga kakuhle.Oku kuya kubangela inkathazo enkulu kumsebenzi kamva: ayinakuhambelana nezinye izixhobo, ukuhanjiswa okungekho semgangathweni, ukunqongophala okukhulu kwebhajethi, njl. Esona sizathu siphambili salo mcimbi kukuba omabini amaqela akacacanga indlela yokubhala iimfuno zePDU.Nantsi indlela elula yokuyenza.

I-1) Umbane wesiphaluka sesebe kwikhabhinethi yoluhlu + umda wokhuseleko = amandla apheleleyo e-PDU kulo mgca.

2) Inani leZixhobo kwi-rack + i-margin yokhuseleko = inani leentengiso kuzo zonke ii-PDU kwi-rack.Ukuba kukho imigca emibini engafunekiyo, inani lePDU kufuneka liphindwe kabini kunye nepharamitha.

I-3) Izixhobo eziphezulu zamandla kufuneka zihlakazwe kwii-PDU ezahlukeneyo ukuze zilungelelanise umbane wesigaba ngasinye.

4) Yenza ngokwezifiso iintlobo zokuphuma kwePDU ngokwezo plug zezixhobo ezingenako ukwahlulwa kwintambo yombane.Ukuba iplagi enokwahlulwa kwintambo yombane ayihambelani, inokusombulula ngokutshintsha intambo yamandla.

5) Xa ukuxinana kwezixhobo kuphezulu kwikhabhinethi, kungcono ukhethe ukufakela ngokuthe nkqo;ngelixa ukuba ukuxinana kwezixhobo kuphantsi, kungcono ukhethe ukufakela okuthe tye.Okokugqibela, iPDU kufuneka inikwe uhlahlo lwabiwo-mali olwahlukileyo ukuthintela ukunqongophala okukhulu kohlahlo lwabiwo-mali.

Ukufakela kunye nokulungiswa kweempazamo

I-1) Amandla ekhabhinethi kufuneka ahambelane namandla esiphaluka sesebe kwikhabhinethi yoluhlu kunye namandla e-PDU, ngaphandle koko kuya kunciphisa ukusetyenziswa kwesalathisi samandla.

I-2) Isikhundla se-U se-PDU kufuneka sigcinelwe ukufakela kwe-PDU ethe tye, ngelixa ukufakwa kwe-PDU ethe nkqo kufuneka ubeke ingqalelo kwi-angle yokunyuka.

Ixesha lokusebenza

1. Nika ingqalelo kwisalathisi sokunyuka kweqondo lokushisa, oko kukuthi, utshintsho lweqondo lokushisa kwiplagi yesixhobo kunye neziseko zePDU.

2. Kwi-PDU yokubeka iliso kude, unokunikela ingqalelo kwiinguqu zangoku ukujonga ukuba ngaba isixhobo sisebenza ngokufanelekileyo.

3. Sebenzisa ngokupheleleyo isixhobo socingo sePDU ukubolisa amandla angaphandle eplagi yesixhobo kwiisokethi zePDU.

Ubudlelwane phakathi kwefom yeevenkile zePDU kunye namandla alinganisiweyo ePDU

Xa usebenzisa i-PDU, sidibana neemeko apho iplagi yesixhobo ayihambelani neziseko zePDU.Ke ngoko, xa sisenza ngokwezifiso iPDU, kufuneka siqale siqinisekise iplagi yesixhobo kunye namandla esixhobo, sithwele umyalelo ngolu hlobo lulandelayo:

Amandla e-socket ephumayo ye-PDU = amandla eplagi yesixhobo ≥ amandla esixhobo.

Ubudlelwane obuhambelanayo phakathi kweplagi kunye neesokethi zePDU zimi ngolu hlobo lulandelayo:
