[Aipuwaton] Yini amandla phezu kwe-Ethernet (Poe)?

Inkinga idinga ukuxazulula

Yini amandla ngaphezulu kwe-ethernet (poe)

Amandla ngaphezulu kwe-Ethernet (POE) ubuchwepheshe bokuguqula abavumela amakhekhe enethiwekhi ukuhambisa amandla kagesi kumadivayisi ahlukahlukene ngaphakathi kwenethiwekhi, aqede isidingo sezitolo ezihlukile zamandla noma adaptha. Le ndlela yenza lula ukufakwa kwamadivayisi, ngoba kungathola womabili amandla nedatha ngentambo eyodwa, kusiza ukuguquguquka okukhulu kanye nokusebenza kahle ekwakheni izingqalasizinda.

Ingabe wonke amakhabethe amakhabethe okusekelwa?

Akuzona zonke izintambo ze-Ethernet ezidaliwe zilingana uma kuziwa ekusekelweni kwe-PoE. Ngenkathi ikati5e noma amakhebuli aphezulu ethernet angasekela i-POE, amakhebula amakati angama-Cat5 angaphatha kuphela ama-voltage aphansi. Kusetshenziswa amakhebuli e-Cat5 kumandla we-Power Class 3 noma ama-Class 4 Amadivayisi (ama-PD) angaholela ezindabeni zokushisa ngokweqile. Ngakho-ke, kubalulekile ukukhetha uhlobo olufanele lwekhebula ngezidingo zakho ze-PoE.

Izicelo ze-poe

Ukuguquguquka okuhlukahlukene kwe-poe kuhlanganisa izinhlobo eziningi zezicelo emikhakheni ehlukahlukene. Amanye amadivaysi ajwayelekile anganikwa amandla nge-poe afaka:

Intuthuko kumazinga wePoe

Okujwayelekile kwakamuva kubuchwepheshe be-POE kuziwa ngokuthi yi-Hi Poe (802.3BT TYPE 4), engahambisa amandla afinyelela kuma-100 WAMANDLA nge-Cat5E Cables. Le ntuthuko ivumela amandla wamadivayisi anamandla amakhulu amandla, akhuthazelele ukusungula nokusebenza. Kodwa-ke, kubalulekile ukuqaphela ukuthi ukukhulisa amandla okwandayo kungaholela ekutheni isizukulwane esiphakeme sokushisa kanye nokulahleka kwamandla okukhulu ngaphakathi kwekhebula.

Izincomo zokusetshenziswa kahle kwe-poe

Ukunciphisa izingqinamba ezihlobene nokushisa kanye nokulahleka kwamandla, ochwepheshe bancoma ukusebenzisa amakhekhe wenethiwekhi ye-100%, enikezela ngokusebenza okungcono kanye nokuphila okude. Ngokwengeziwe, ukugwema ukusetshenziswa kwama-poe litjectors noma ukushintshwa okungase kungasekeli ukulethwa kwamandla okusebenzayo kuyalulekwa. Ngokusebenza okuthe xaxa, izintambo zekati6 ziyindlela ephakeme ngenxa yabaqhubi bawo obukhulu bethusi, ethuthukisa ukuncipha kokushisa kanye nokusebenza okuphelele kwezicelo ze-POE.

Ukugcina

Ekuphetheni, Amandla ngaphezulu kwe-Ethernet (Poe) yisisombululo esiguqula umdlalo esenza lula ukulethwa kwamandla kumadivayisi anethiwekhi anezinkundla Njengoba ubuchwepheshe buyaqhubeka nokuvela, i-POE ihlala iyisidlali esibalulekile kumadivayisi anika amandla ngempumelelo, okufaka isandla kubukhali futhi kuxhumeke ezindaweni ezixhunyiwe kuzo zonke izicelo ezahlukahlukene. Ngokuqonda amakhono ayo nokusebenzisa imikhuba emihle kakhulu, abasebenzisi bangasiza ngokuphelele izinzuzo zalobu buchwepheshe obusha.
