Abangani abaningi abasebenza ekuqaphelweni kwezokuphepha kanye nobunjiniyela bokuhlanganisa okungenantambo banokuqonda okuhle kokunikezwa kwamandla e-POE futhi bayaqaphela izinzuzo zokuphakelwa kukagesi kwe-PoE. Kodwa-ke, kuzintambo zangempela zobunjiniyela, bathole ukuthi ukuthunyelwa kwe-PoE kunemikhawulo eminingi, njengokusebenzisa izindlela zezintambo zendabuko lapho ukuphela okuphezulu kushintshwa kanye namadivayisi aphansi angayisekeli i-POE.
Njengoba kwaziwa, izindlela zezintambo zendabuko zinezindleko eziphezulu zokufaka izintambo kanye nezabasebenzi, ezingahambisani nokulungiswa okulandelayo. Lesi sihloko sihlola izindlela ezine zokusetshenziswa konjiniyela zokuphakelwa kwamandla kwe-PoE. Ngemva kokuzijwayeza ngalezi zindlela ezine, ungasebenzisa ukutholakala kwamandla kagesi kwe-PoE ukuze unciphise ukukhathazeka kunoma yisiphi isimo.
1. Kokubili amaswishi namatheminali asekela i-PoE
Le ndlela ilula kakhulu ukuthi amaswishi e-POE axhunywe ngokuqondile kuma-AP angenantambo namakhamera enethiwekhi asekela ukunikezwa kwamandla e-POE ngamakhebuli enethiwekhi. Nokho, amaphuzu amabili alandelayo kufanele futhi aqashelwe:
1. Thola ukuthi ukushintsha kwe-POE kanye ne-AP engenantambo noma ikhamera yenethiwekhi kungamadivayisi ajwayelekile e-POE
2. Kuyadingeka ukuqinisekisa ngokucophelela ukucaciswa kwekhebula lenethiwekhi elithengiwe. Ikhwalithi yekhebula yenethiwekhi ibalulekile. Izintambo zenethiwekhi ezisezingeni eliphansi zingabangela i-AP noma i-IPC ukuthi ingakwazi ukuthola amandla noma iqale kabusha njalo
2, Ukushintsha kusekela i-POE, i-terminal ayisekeli i-POE
Lolu hlelo luxhuma ukushintsha kwe-POE kusihlukanisi se-POE, esihlukanisa ukunikezwa kwamandla kumasignali wedatha namandla. Kunemigqa emibili yokuphumayo, owodwa ulayini wokuphuma kwamandla, kanti omunye ulayini ophumayo wesignali yedatha yenethiwekhi, okuyintambo yenethiwekhi evamile. Amandla okukhipha amandla ahlanganisa i-5V/9/12V namanye amatheminali okungewona e-POE angakwazi ukufanisa okokufaka okuhlukahlukene kwe-DC, okusekela izinga le-IEEE802.3af/802.3at. Ikhebuli yokukhipha isignali yedatha, eyaziwa nangokuthi ikhebuli yenethiwekhi evamile, ingaxhunywa ngokuqondile embobeni yenethiwekhi yetheminali engeyona i-POE eyamukelayo.
3, Ukushintsha akusekeli i-POE, i-terminal isekela i-POE
Lolu hlelo lubandakanya ukuxhuma iswishi kugesi we-POE, owengeza amandla kukhebula lenethiwekhi futhi liwathumele kutheminali. Lesi sixazululo sifanelekile ekwandiseni inethiwekhi yezintambo ekhona ngaphandle kokuthinta inethiwekhi yoqobo.
4, Iswishi ayisekeli i-POE, futhi isiphetho asisekeli i-POE
Lolu hlelo luhlanganisa ukuxhuma iswishi kugesi we-PoE, bese kuba isihlukanisi se-POE, futhi ekugcineni siyidlulisele kutheminali.
I-Scheme 3 kanye ne-Scheme 4 zilungele ukuguqulwa kwamanethiwekhi omdabu, lapho ukushintshwa kwangempela kungazange kusekele ukuphakelwa kukagesi kwe-POE kodwa befuna ukusizakala ngezinzuzo zokuphakelwa kukagesi kwe-POE.
Kafushane, i-POE ingasetshenziswa kunoma yisiphi isimo, ikwenze kube lula ukusebenzisa izinsiza ezihlukahlukene ezilethwa yi-POE. Kubalulekile futhi ukukhetha ukushintshwa kwe-PoE. Ukushintsha okuhle kwe-POE kungenza yonke isistimu izinze futhi kube lula ukuyinakekela. Iswishi ye-POE ye-CF FIBERLINK nesihlukanisi se-POE zinekhwalithi eqinisekisiwe, enekhwalithi enhle kakhulu.
