Ezweni lanamuhla elikhula ngedijithali, isidingo sokuxhumeka kwe-inthanethi okusheshayo nokuthembekile sikhulu kunanini ngaphambili. Lokhu kuyiqiniso ikakhulukazi emabhizinisini nasezinhlanganweni, lapho ukuxhumana kwenethiwekhi okuzinzile kubalulekile ekusebenzeni kwansuku zonke. Yilapho izinkinobho ze-Power over Ethernet (PoE) ziqala khona ukusebenza.
KuyiniIswishi ye-PoEUyabuza? Ziyi-network switch ezihlinzeka ngamandla kanye nokudluliselwa kwedatha ngezintambo ze-Ethernet kumadivayisi afana namakhamera e-IP, amafoni e-VoIP, kanye nezindawo zokufinyelela ezingenantambo. Lokhu kuqeda isidingo sentambo kagesi ehlukile, okwenza ukufakwa nokugcinwa kube lula.
Enye yezinzuzo eziyinhloko zamaswishi e-PoE yikhono lokunika amandla amadivayisi amabanga amade (kufika kumamitha ayi-100). Lokhu kuwusizo ikakhulukazi ekufakweni kwangaphandle noma ezindaweni lapho iziteshi zikagesi zingase zingabi khona. Ngaphezu kwalokho,Izishintshi ze-PoEingabeka phambili futhi iphathe ukusatshalaliswa kwamandla ukuqinisekisa ukuthi amadivayisi abalulekile athola amandla kuqala.
Uma ukhetha iswishi ye-PoE, kunezici eziningana ezibalulekile okufanele uzicabangele. Okokuqala, isabelomali samandla seswishi sibalulekile ngoba sibonisa ukuthi iswishi inganikeza amandla angakanani kumadivayisi axhunyiwe. Futhi cabanga ngenani lamachweba e-PoE adingekayo, kanye nesivinini sokudlulisa idatha seswishi kanye nokusebenza kwenethiwekhi iyonke.
Okunye okubalulekile okufanele kucatshangelwe ukuhambisana kweswishi ye-PoE nemishini eyisebenzisayo. Kubalulekile ukuqinisekisa ukuthi iswishi ingahlinzeka ngezidingo zamandla ezidingekayo kuwo wonke amadivayisi axhunyiwe futhi isekele amaphrothokholi enethiwekhi adingekayo.
Ngokuphathelene nokufakwa, amaswishi e-PoE alula ukuwasetha. Angahlanganiswa kalula kumanethiwekhi akhona futhi eze ngobukhulu obuhlukahlukene kanye nokucushwa ukuze kuhlangatshezwane nezidingo ezahlukene. Amaswishi amaningi e-PoE abuye abe nesofthiwe yokuphatha eyenza kube lula ukuqapha nokulawula amadivayisi axhunyiwe.
Ngaphezu kokusebenza kwazo, ama-PoE switch angonga izindleko futhi andise ukusebenza kahle kwamandla. Ngokusebenzisa ikhebula elilodwa lokudlulisa amandla kanye nedatha, amabhizinisi anganciphisa inani lezintambo ezidingekayo, ngaleyo ndlela ehlise izindleko zokufaka nokulungisa. Ngaphezu kwalokho, ikhono lokuqalisa kabusha amadivayisi kude nge-PoE switch longa isikhathi nezinsiza.
Sekukonke, i-PoE switch iyisisombululo esisebenziseka kalula nesisebenzayo sokunika amandla nokuphatha amadivayisi axhunywe kunethiwekhi. Amandla abo okuhlinzeka ngamandla nokudluliselwa kwedatha ngekhebula elilodwa le-Ethernet kubenza bafanelekele izinhlelo zokusebenza ezahlukahlukene kusukela emabhizinisini amancane kuya emabhizinisini amakhulu.
Ekuphetheni,Izishintshi ze-PoEzingamathuluzi awusizo okuhlangabezana nezidingo zamanethiwekhi anamuhla. Ikhono lazo lokwenza lula ukufakwa, ukunciphisa izindleko kanye nokuhlinzeka ngamandla asebenzayo kanye nokudluliswa kwedatha kuzenza zibe yinto ebalulekile kunoma iyiphi inhlangano efuna ukwenza lula ingqalasizinda yayo yenethiwekhi. Kungakhathaliseki ukuthi kunika amandla amakhamera e-IP, amafoni e-VoIP, noma izindawo zokufinyelela ezingenantambo, ama-PoE switch ayisisombululo esikhethwayo sokuxhumana okuthembekile nokungenazinkathazo.
