    Iyini iswishi ye-PoE enikwe amandla yinethiwekhi?

    Isikhathi sokuthumela: Sep-15-2020

    Ngaphambi kokuqonda i-PoEamaswishi, kufanele siqale siqonde ukuthi i-PoE iyini.

    I-PoE iwumthombo wamandla ngaphezu kobuchwepheshe be-Ethernet. Kuyindlela yokunikeza amandla ukude kumadivayisi enethiwekhi axhunyiwe (njenge-Wireless LAN AP, Ucingo lwe-IP, i-Bluetooth AP, Ikhamera ye-IP, njll.) kukhebula yedatha ye-Ethernet evamile, ukususa Inkinga yokufaka idivayisi ehlukile yokuphakela amandla Idivayisi yetheminali yenethiwekhi ye-IP ikwenza kungadingeki ukuthi kusetshenziswe isistimu yokuphakelwa kwamandla ehlukile yedivayisi endaweni yokusetshenziswa, enganciphisa kakhulu izindleko zezintambo nokuphatha zokuphakelwa kwamatheminali futhi ikhuthaze ukuthuthukiswa kwezinkambu ezihlobene.

    IShintshanisa amasheya PoEkusekelwe kwendabukoUkushintsha kwe-Ethernet, ngokungezwa komsebenzi we-PoE ngaphakathi, ukuze ishintshaayinawo umsebenzi wokushintshanisa idatha kuphela, kodwa futhi ingadlulisela amandla ngekhebula lenethiwekhi ngesikhathi esifanayo. Lokhu ukunikezwa kwamandla enethiwekhishintsha. Ingahlukaniswa kokujwayelekileamaswishingokubukeka. Amaswishi e-PoE anegama elithi “PoE” ngaphambili kwephaneli, okubonisa ukuthi anemisebenzi ye-PoE, kuyilapho amaswishi avamile engenawo.

    Ukuqaphela ukunikezwa kwamandla enethiwekhi ngokushintsha kwe-PoE kunezinzuzo eziningi.

    1.Ukuthunyelwa okulula. Asikho isidingo sokumba imigodi, ukudonsa izintambo, noma ukufaka amasokhethi amandla ukuze usebenzise i-PoE. Udinga eyodwa kuphelaImbobo ye-RJ45ukuhlinzeka ngezindlela ezihlukene zokunikezwa kwamandla kumadivayisi ezindaweni ezahlukene nge-Ethernet ekhona.

    2.Okuvumelana nezimo. Nge-PoE, indawo yokufakwa kwamakhamera enethiwekhi nezindawo zokufinyelela okungenantambo akusakhawulelwe. Noma ngabe ikude kangakanani isokhethi yamandla e-AC, ingasatshalaliswa noma kuphi lapho kudingeka khona, okwenza nokuqapha kwenethiwekhi kuphelele kakhulu.

    3.Kuvikeleke kakhudlwana. Uma kuqhathaniswa ne-AC power supply,Ukunikezwa kwamandla kwe-PoEingeyesigaba samanje esibuthakathaka, futhi ayikho ingcuphe yokuphepha yomsinga oqinile. Ngaphezu kwalokho, amandla anikezwa ngentambo yenethiwekhi. Kuphela uma okokusebenza okudinga ukuphakelwa kwamandla kuxhunyiwe, ikhebuli ye-Ethernet izoba ne-voltage, esusa ubungozi bokuvuza emugqeni.

    4.Izindleko eziphansi. Izindleko ezishiwo lapha azibhekiseli kuphela emalini, kodwa futhi zihlanganisa izindleko zesikhathi. Izintambo zikagesi zendabuko zidinga izindleko zabasebenzi futhi zidinga isikhathi esithile ukuqeda, okuyizindleko ezinkulu. Isebenzisa i-PoE kuphelashintshangokunikezwa kwamandla, akukho msebenzi wezandla noma isikhathi esiningi, ngokuyisisekelo xhuma futhi udlale, kulula kakhulu, kulula futhi kuyashesha.

    5.Ukuphatha okulula. Ukuphathwa nokugcinwa kwesistimu yokuqapha evamile kuyinkimbinkimbi kakhulu futhi kunzima. Ukusebenzisa amandla e-PoE kungalawula ukude, ukulungisa kabusha noma ukusetha kabusha amakhamera enethiwekhi kanye nezindawo zokufinyelela ezingenantambo.

    Ukushintsha kwe-PoEhlinzeka ngamakhamera enethiwekhi ngokuthuthukiswa kokuthembeka, ukunciphisa izindleko, kanye nokusetshenziswa kalula. Ngokuthuthuka okunamandla kokubhekwa kwenethiwekhi, amakhamera amaningi wenethiwekhi anganikwa amandla yi-PoE.
