Yini Amandla phezu kwe-Ethernet(POE)

Amandla phezu kwe-Ethernet (i-PoE) ubuchwepheshe obuguqulayo obuvumela izintambo zenethiwekhi ukuthi zidlulisele amandla kagesi kumadivayisi ahlukahlukene ngaphakathi kwenethiwekhi, okuqeda isidingo sezindawo ezihlukene zikagesi noma ama-adaptha. Le ndlela yenza ukufakwa kwamadivayisi kube lula, njengoba angathola kokubili amandla kanye nedatha ngekhebula elilodwa, kube lula ukuguquguquka okukhulu nokusebenza kahle kwingqalasizinda yokwakha.

Ingabe Wonke Amakhebuli E-Ethernet Asekela I-PoE?

Akuwona wonke amakhebuli e-Ethernet adalwe alingana uma kukhulunywa ngokusekela i-PoE. Nakuba izintambo ze-Cat5e noma ze-Ethernet eziphezulu zingasekela i-PoE, izintambo ze-Cat5 zingaphatha kuphela ama-voltage aphansi. Ukusebenzisa izintambo ze-Cat5 ukunika amandla Ikilasi 3 noma Amadivayisi Anamandla Ekilasi 4 (ama-PD) kungaholela ezinkingeni zokushisisa ngokweqile. Ngakho-ke, kubalulekile ukukhetha uhlobo olulungile lwekhebula ngezidingo zakho ze-PoE.

Izicelo ze-PoE

Ukuguquguquka kwe-PoE kuhlanganisa izinhlobonhlobo zezinhlelo zokusebenza emikhakheni eyahlukene. Amanye amadivayisi ajwayelekile anganikwa amandla nge-PoE afaka:

Ukukhanyisa kwe-LED, amakhiwokhi, izinzwa zokuhlala, amasistimu ama-alamu, amakhamera, ama-Monitor, ama-Window shades, amakhompyutha aphathekayo ane-USB-C, ama-Air conditioner, neziqandisi.

Ukuthuthuka Kwamazinga we-PoE

Izinga lakamuva kubuchwepheshe be-PoE laziwa nge-Hi PoE (802.3bt Type 4), elingaletha amandla afinyelela kwangu-100 W ngezintambo ze-Cat5e. Lokhu kuthuthukiswa kuvumela ukunikwa amandla kwemishini edla amandla kakhudlwana, kugqugquzelwe ukusungulwa kanye nokusebenza. Nokho, kubalulekile ukuqaphela ukuthi ukukhushulwa kokulethwa kwamandla kungaholela ekukhiqizeni ukushisa okuphezulu nokulahlekelwa okukhulu kwamandla ngaphakathi kwekhebuli.

Izincomo Zokusetshenziswa Okulungile kwe-PoE

Ukuze unciphise izinkinga ezihlobene nokushisa ezingaba khona nokulahlekelwa amandla, ochwepheshe batusa ukusebenzisa izintambo zenethiwekhi zethusi ezingu-100%, ezinikeza ukuqhutshwa okungcono nokuhlala isikhathi eside. Ukwengeza, ukugwema ukusetshenziswa kwezijovo ze-PoE noma amaswishi okungenzeka angakusekeli ukulethwa kwamandla okuphumelelayo kuyancomeka. Ngokusebenza okukhulu nakakhulu, izintambo ze-Cat6 ziyinketho ephakeme kakhulu ngenxa yamakhondaktha azo ethusi aminyene, athuthukisa ukuchithwa kokushisa nokusebenza kahle okuphelele kwezinhlelo ze-PoE.

Isiphetho

Sengiphetha, i-Power over Ethernet (i-PoE) iyisixazululo esishintsha umdlalo esenza lula ukulethwa kwamandla kumadivayisi anenethiwekhi kuyilapho kuthuthukisa ukusebenza kwawo nokuhlanganiswa ngaphakathi kwengqalasizinda ekhona. Njengoba ubuchwepheshe buqhubeka nokuvela, i-PoE isalokhu ingumdlali obalulekile ekunikezeni amandla amadivayisi ngempumelelo, inikela ezindaweni ezihlakaniphile nezixhumeke kakhulu kuzo zonke izinhlelo zokusebenza ezihlukahlukene. Ngokuqonda amandla ayo nokusebenzisa imikhuba ehamba phambili, abasebenzisi bangakwazi ukusebenzisa ngokugcwele izinzuzo zalobu buchwepheshe obusha.
