Kwihlabathi lanamhlanje elikhula ngokwedijithali, isidingo soqhagamshelo lwe-intanethi olukhawulezayo noluthembekileyo sikhulu kunangaphambili. Oku kuyinyani ngakumbi kumashishini nakwimibutho, apho uqhagamshelo lwenethiwekhi oluzinzileyo lubalulekile kwimisebenzi yemihla ngemihla. Kulapho ke ii-Power over Ethernet (PoE) switches ziqala khona ukusebenza.
Yintoni iUtshintsho lwePoEUyabuza? Ziiswitshi zenethiwekhi ezibonelela ngombane kunye nokudluliselwa kwedatha kwiintambo ze-Ethernet ukuya kwizixhobo ezifana neekhamera ze-IP, iifowuni ze-VoIP, kunye neendawo zokufikelela ezingenazingcingo. Oku kususa imfuneko yentambo yombane eyahlukileyo, okwenza ukufakwa kunye nokugcinwa kube lula.
Enye yezona nzuzo ziphambili zeeswitshi zePoE kukukwazi ukunika amandla izixhobo kumgama omde (ukuya kuthi ga kwiimitha ezili-100). Oku kuluncedo ngakumbi kwiindawo zangaphandle okanye kwiindawo apho iindawo zokufaka umbane zinqabile khona. Ukongeza,Iiswitshi zePoEbanokubeka phambili kwaye balawule ukusasazwa kwamandla ukuqinisekisa ukuba izixhobo ezibalulekileyo zifumana amandla kuqala.
Xa ukhetha iswitshi yePoE, kukho izinto ezibalulekileyo ekufuneka ziqwalaselwe. Okokuqala, uhlahlo lwabiwo-mali lwamandla lweswitshi lubalulekile kuba lubonisa ukuba iswitshi inokubonelela ngamandla angakanani kwizixhobo ezixhunyiweyo. Kwakhona qwalasela inani leeports zePoE ezifunekayo, kunye nesantya sokudlulisa idatha yeswitshi kunye nokusebenza kwenethiwekhi iyonke.
Enye into ebalulekileyo ekufuneka iqwalaselwe kukuhambelana kweswitshi yePoE nezixhobo ezisebenza kuyo. Kubalulekile ukuqinisekisa ukuba iswitshi inokubonelela ngeemfuno zamandla ezifunekayo kuzo zonke izixhobo ezixhunyiweyo kwaye ixhase iiprotokholi zenethiwekhi ezifunekayo.
Ngokuphathelele ukufakwa, iiswitshi zePoE zilula ukuziseta. Zingadityaniswa lula kwiinethiwekhi ezikhoyo kwaye ziza ngobukhulu obahlukeneyo kunye noqwalaselo ukuhlangabezana neemfuno ezahlukeneyo. Uninzi lweeswitshi zePoE lukwaza nesoftware yolawulo eyenza kube lula ukujonga nokulawula izixhobo eziqhagamshelweyo.
Ukongeza ekusebenzeni kwazo, ii-PoE switches zinokonga iindleko kwaye zonyuse ukusebenza kakuhle kwamandla. Ngokusebenzisa intambo enye yombane kunye nokudluliselwa kwedatha, amashishini anokunciphisa ubungakanani bentambo efunekayo, ngaloo ndlela ehlisa iindleko zokufakela kunye nokugcinwa. Ukongeza, ukukwazi ukuqalisa kwakhona izixhobo kude nge-PoE switch konga ixesha kunye nezixhobo.
Lilonke, iswitshi yePoE sisisombululo esisebenziseka lula nesisebenzayo sokunika amandla nokulawula izixhobo eziqhagamshelwe kwinethiwekhi. Ukukwazi kwazo ukubonelela ngombane kunye nokudluliselwa kwedatha ngentambo enye ye-Ethernet kuzenza zilungele ukusetyenziswa kwezicelo ezahlukeneyo ukusuka kumashishini amancinci ukuya kumashishini amakhulu.
Ukuququmbela,Iiswitshi zePoEzizixhobo ezixabisekileyo zokuhlangabezana neemfuno zenethiwekhi zanamhlanje. Ukukwazi kwazo ukwenza lula ukufakela, ukunciphisa iindleko kunye nokubonelela ngamandla asebenzayo kunye nokudluliselwa kwedatha kuzenza zibe yinto ebalulekileyo kuyo nayiphi na intlangano efuna ukwenza lula iziseko zayo zenethiwekhi. Nokuba kukunika amandla iikhamera ze-IP, iifowuni ze-VoIP, okanye iindawo zokufikelela ezingenazingcingo, iiswitshi ze-PoE zisisombululo esikhethwayo sokunxibelelana okuthembekileyo nokungenaxhala.
