Amandla phezu kwe-Ethernet (i-PoE) ubuchwepheshe bokuhlinzeka ngogesi obusekelwe kunethiwekhi yendawo (LAN), engadlulisela amandla nedatha kudivayisi ngentambo yenethiwekhi eku-Ethernet. Ukusetshenziswa kwalobu buchwepheshe kunganciphisa kakhulu izindleko zokusebenza futhi konge isikhathi sokusebenza. Njengamanje, kukhona ukushintsha okuhlukahlukene okusekelwe kubuchwepheshe be-PoE emakethe, ikakhulukazi ukushintsha kwe-PoE, ukushintsha kwe-PoE+, namaswishi e-PoE++. Sicela ulandeleI-JHA TECHukuqonda umehluko phakathi kwalezi zinguquko.

Iyini i-PoE? Kuyini ukushintshwa kwe-PoE?

I-PoE (ebizwa nangokuthi i-IEEE 802.3af standard) iyindinganiso entsha esekelwe ohlelweni lwamandla phezu kwe-Ethernet olwamenyezelwa iqembu elisebenzayo le-IEEE 802.3 ngo-2003. Izinga libeka ukuthi idivayisi eyamukela amandla (PD), njengefoni ye-VoIP. , idinga kuphela ukusebenzisa amapheya amabili asontekile entambo yenethiwekhi efanayo ukuze inikwe amandla ngesikhathi senqubo yokwamukela amandla, futhi ukusetshenziswa kwayo kwamandla e-PoE kungafinyelela ku- 12.95W.

I-PoE switch, ebizwa nangokuthi i-PoE power supply switch, uhlelo lokusebenza olusekelwe kubuchwepheshe be-PoE. Kuwushintsho olunganikeza amandla kanye nokudluliswa kwedatha kutheminali eyamukelayo ngesikhathi esifanayo ngekhebula yenethiwekhi, futhi ingeyemishini yokugcina ugesi (PSE). Ngokuvamile, ukushintsha kwe-PoE okuvumelana nezinga le-802.3af kungasekela ukunikezwa kwamandla okuphezulu okungu-15.4W ngembobo ngayinye, futhi amandla kagesi aphuma ku-44V-57V. I-voltage yokufaka yedivayisi ye-PoE exhunywe kule swishi ye-PoE ingu-37V-57V.

Yini i-PoE+? Iyini iswishi ye-PoE+?

I-PoE+ (ebuye ibizwe ngokuthi yi-IEEE 802.3af standard), njengokuthuthukela kubuchwepheshe be-PoE, iyindinganiso yezobuchwepheshe ye-PoE eyakhishwa ngo-2009. Ngokusetshenziswa kabanzi kobuchwepheshe be-PoE, ezinye izisetshenziswa zokwamukela amandla njengama-AP angenawaya zidinga amandla amaningi kakhulu. ngaphezu kwe-12.95W. Ukuze kuxazululwe le nkinga, iqembu elisebenzayo le-IEEE 802.3 likhiphe ubuchwepheshe be-PoE+ obuklanyelwe ukunikeza amandla aphezulu kumadivayisi.

Iswishi ye-PoE+ iyafana neswishi ye-PoE esiyishilo ngenhla, futhi inikeza amandla kudivayisi yetheminali ye-PoE ngentambo yenethiwekhi. Umehluko ukuthi ukunikezwa kwamandla okuphezulu kwembobo ngayinye yeswishi ye-PoE+ ngu-30W, kanye ne-voltage yokuphakela amandla ngu-50V-57V. Ukunikezwa kwamandla okuphezulu okutholwe idivayisi yokwamukela amandla kungakhushulwa ku-25.5W, futhi i-voltage inganyuswa ibe ngu-42.5V-57V.

Yini i-PoE++? Iyini ukushintsha kwe-PoE++?

Ngokuthuthuka okuqhubekayo kwemakethe yezicelo ze-PoE, izinga le-IEEE 802.3 lengeze izinga le-IEEE 802.3bt. Kuleli qophelo, ubuchwepheshe be-PoE ++ buye bavela. Ngaphansi kwezinga le-IEEE 802.3bt, ubuchwepheshe be-PoE++ bunezinhlobo ezimbili zamagatsha. Ubuchwepheshe obubodwa be-PoE++ obubizwa nge-Type3 bunganikwa amandla ngamapheya amabili noma amane asontekile ekhebuli yenethiwekhi efanayo, futhi bunganikeza amandla okufaka afika ku-51W wedivayisi eyamukela amandla.Obunye ubuchwepheshe be-Type4PoE++, obudinga ukunikeza amandla ku-PoE. idivayisi yokugcina kuwo wonke amapheya ekhebula lenethiwekhi, namandla okufaka angafinyelela ku-71W. Ngaphezu kwalokho, kunobuchwepheshe be-PoE obusekelwe ezingeni le-IEEE 802.3bt elibizwa ngokuthi i-UPOE (amandla omhlaba wonke phezu kwe-Ethernet). Lobu buchwepheshe buphathelene ne-Cisco, futhi imodi yokusebenza ifana nobuchwepheshe be-Type3PoE (PoE++), futhi amandla okufaka anganikezwa kudivayisi yokugcina eyamukelayo ngu-51W. Ngakho-ke, abanye abantu embonini bazophinde babheke i-UPOE njenge-PoE++.

Njengokuthuthukela ekushintsheni kwe-PoE namaswishi e-PoE+, amaswishi e-PoE++ anganikeza amandla afinyelela kwangu-60W ngembobo ngayinye yokushintsha kwe-Type3PoE++, kanye no-100W ku-Type4. Bheka ithebula elingezansi ukuze ubuke imingcele ethile yokushintsha kwe-PoE++ nezinye izinhlobo ezimbili zamaswishi.
