Ezweni lanamuhla elikhula ngokwedijithali, isidingo soxhumano lwe-inthanethi olunesivinini esikhulu, oluthembekile sikhulu kunangaphambili. Lokhu kuyiqiniso ikakhulukazi kumabhizinisi nezinhlangano, lapho uxhumano lwenethiwekhi oluzinzile lubalulekile ekusebenzeni kwansuku zonke. Kulapho amaswishi Amandla phezu kwe-Ethernet (PoE) aqala khona ukusebenza.
Yini aShintshanisa amasheya PoEuyabuza? Amaswishi enethiwekhi anikeza amandla kanye nokudluliswa kwedatha ngezintambo ze-Ethernet ukuya kumadivayisi afana namakhamera we-IP, amafoni e-VoIP, nezindawo zokufinyelela ezingenantambo. Lokhu kuqeda isidingo sentambo kagesi ehlukile, okwenza ukufakwa nokugcinwa kube lula.
Enye yezinzuzo eziyinhloko zokushintshwa kwe-PoE yikhono lokunika amandla amadivaysi ebangeni elide (kufika kumamitha angu-100). Lokhu kuwusizo ikakhulukazi ekufakweni kwangaphandle noma ezindaweni lapho izitolo zikagesi zingase ziyindlala. Ngaphezu kwalokho,Ukushintsha kwe-PoEingabeka kuqala futhi ilawule ukusatshalaliswa kwamandla ukuze kuqinisekiswe ukuthi amadivayisi abalulekile athola amandla kuqala.
Lapho ukhetha ukushintshwa kwe-PoE, kunezici ezimbalwa ezibalulekile okufanele uzicabangele. Okokuqala, isabelomali samandla sokushintsha sibalulekile ngoba sibonisa ukuthi mangakanani amandla okushintshwa okungawanikeza kumadivayisi axhunyiwe. Futhi cabangela inombolo yezimbobo ze-PoE ezidingekayo, kanye nesivinini sokudlulisa idatha soshintsho kanye nokusebenza kwenethiwekhi kukonke.
Okunye okucatshangelwayo okubalulekile ukuhambisana kweswishi ye-PoE nemishini eyinika amandla. Kubalulekile ukuqinisekisa ukuthi iswishi inganikeza izidingo zamandla ezidingekayo kuwo wonke amadivayisi axhunyiwe futhi isekele izivumelwano zenethiwekhi ezidingekayo.
Ngokufaka ubuhlakani, amaswishi e-PoE alula ukusethwa. Angahlanganiswa kalula kumanethiwekhi akhona futhi eze ngobukhulu obuhlukahlukene kanye nokucushwa ukuze ahlangabezane nezidingo ezahlukene. Amaswishi amaningi e-PoE nawo eza nesofthiwe yokuphatha eyenza kube lula ukuqapha nokulawula amadivayisi axhunyiwe.
Ngokungeziwe ekusebenzeni kwabo, ukushintsha kwe-PoE nakho kungasindisa izindleko futhi kukhuphule ukusebenza kahle kwamandla. Ngokusebenzisa ikhebula elilodwa lamandla kanye nokudluliswa kwedatha, amabhizinisi anganciphisa inani lezintambo ezidingekayo, ngaleyo ndlela ehlise izindleko zokufaka nokulungisa. Ukwengeza, ikhono lokuqalisa kabusha amadivayisi ukude ngokushintsha kwe-PoE konga isikhathi nezinsiza.
Sekukonke, ukushintshwa kwe-PoE kuyisixazululo esiguquguqukayo nesisebenzayo sokunika amandla nokuphatha amadivayisi axhumeke kunethiwekhi. Ikhono labo lokuhlinzeka ngamandla nokudluliswa kwedatha ngekhebula elilodwa le-Ethernet libenza balungele izinhlelo zokusebenza ezihlukahlukene kusukela kumabhizinisi amancane kuya kumabhizinisi amakhulu.
Ekuphetheni,Ukushintsha kwe-PoEzingamathuluzi abalulekile okuhlangabezana nezidingo zamanethiwekhi esimanje. Ikhono labo lokwenza ukufakwa kube lula, ukunciphisa izindleko kanye nokuhlinzeka ngamandla asebenzayo nokudluliswa kwedatha kubenza babe khona kunoma iyiphi inhlangano efuna ukwenza ingqalasizinda yenethiwekhi ibe lula. Ukuthi unika amandla amakhamera we-IP, amafoni e-VoIP, noma izindawo zokufinyelela ezingenantambo, amaswishi e-PoE ayisixazululo sokuzikhethela sokuxhumana okuthembekile, okungenakukhathazeka.
