Kwihlabathi lanamhlanje elandayo ledijithali, imfuno yesantya esiphezulu, uqhagamshelo oluthembekileyo lwe-intanethi inkulu kunangaphambili. Oku kuyinyani ngakumbi kumashishini kunye nemibutho, apho unxibelelwano lwenethiwekhi oluzinzileyo lubalulekile kwimisebenzi yemihla ngemihla. Apha kulapho Amandla phezu kwe-Ethernet (PoE) iiswitshi ziza kudlala.
Yintoni naUkutshintsha kwePoEuyabuza? Zizitshintshi zenethiwekhi ezibonelela ngamandla kunye nokuhanjiswa kwedatha kwiintambo ze-Ethernet kwizixhobo ezifana neekhamera ze-IP, iifowuni zeVoIP, kunye neendawo zokufikelela ezingenazintambo. Oku kuphelisa imfuno yentambo yombane eyahlukileyo, ukwenza ukufakela kunye nokugcinwa kube lula.
Enye yeenzuzo eziphambili zokutshintsha kwe-PoE kukukwazi ukwenza izixhobo zombane kumgama omde (ukuya kwi-100 yeemitha). Oku kuluncedo ngakumbi kufakelo lwangaphandle okanye iindawo apho iindawo zokukhupha umbane zinokunqongophala. Ukwengeza,Iiswitshi zePoEinokubeka phambili kwaye ilawule ukuhanjiswa kwamandla ukuqinisekisa ukuba izixhobo ezibalulekileyo zifumana amandla kuqala.
Xa ukhetha utshintsho lwe-PoE, kukho izinto ezininzi ezibalulekileyo ekufuneka uziqwalasele. Okokuqala, uhlahlo lwabiwo-mali lwamandla okutshintsha lubalulekile kuba lubonisa ukuba ubungakanani bamandla okutshintsha unokubonelela ngezixhobo ezixhunyiwe. Kwakhona qwalasela inani leezibuko ze-PoE ezifunekayo, kunye nesantya sokudluliselwa kwedatha yokutshintsha kunye nokusebenza kwenethiwekhi ngokubanzi.
Olunye uqwalaselo olubalulekileyo kukuhambelana kokutshintsha kwePoE kunye nesixhobo esisinika amandla. Kubalulekile ukuqinisekisa ukuba utshintsho lunokubonelela ngeemfuno zamandla eziyimfuneko kuzo zonke izixhobo ezixhunyiwe kunye nokuxhasa iiprothokholi zenethiwekhi ezifunekayo.
Ufakelo-bulumko, iiswitshi ze-PoE zilula ukuseta. Ziyakwazi ukudityaniswa lula kwiinethiwekhi ezikhoyo kwaye ziza kwiindidi ezahlukeneyo zobukhulu kunye noqwalaselo ukuhlangabezana neemfuno ezahlukeneyo. Uninzi lweeswitshi ze-PoE nazo ziza nesoftware yolawulo eyenza kube lula ukujonga nokulawula izixhobo eziqhagamshelweyo.
Ukongeza ekusebenzeni kwabo, iiswitshi ze-PoE zinokonga iindleko kunye nokwandisa ukusebenza kakuhle kwamandla. Ngokusebenzisa ikhebula elilodwa lombane kunye nokuhanjiswa kwedatha, amashishini anokunciphisa inani le-wiring efunekayo, ngaloo ndlela ehlisa iindleko zokufakela kunye nokugcinwa. Ukongeza, ukukwazi ukuqalisa ngokutsha izixhobo ngokutshintsha kwePoE konga ixesha kunye nezixhobo.
Ngokubanzi, utshintsho lwe-PoE sisisombululo esiguquguqukayo nesisebenzayo sokunika amandla kunye nokulawula izixhobo eziqhagamshelwe kwinethiwekhi. Ukukwazi kwabo ukubonelela ngamandla kunye nokuhanjiswa kwedatha kwikhebula elilodwa le-Ethernet libenza bafaneleke kwiintlobo ezahlukeneyo zezicelo ezivela kumashishini amancinci ukuya kumashishini amakhulu.
Ukuququmbela,Iiswitshi zePoEzizixhobo ezixabisekileyo zokuhlangabezana neemfuno zothungelwano lwale mihla. Ukukwazi kwabo ukwenza lula ukufakela, ukunciphisa iindleko kunye nokubonelela ngamandla asebenzayo kunye nokudluliselwa kwedatha kwenza kube yinto efunekayo kuyo nayiphi na inhlangano efuna ukwenza lula iziseko zabo zenethiwekhi. Ingaba iikhamera ze-IP zamandla, iifowuni zeVoIP, okanye iindawo zokufikelela ezingenazintambo, iiswitshi ze-PoE ziyisisombululo sokhetho oluthembekileyo, uxhulumaniso olungenaxhala.
