Ukutshintsha kwePoEibhekisa kutshintsho olunokubonelela ngonikezelo lwamandla womnatha kwiitheminali ezisebenza kude ngentambo yenethiwekhi. Sisixhobo esiqhelekileyo sonikezelo lwamandla kwiinkqubo zobonelelo lwamandla e-PoE. Nangona kunjalo, ukuba umtshintshi awunawo umsebenzi we-POE, ngaba imodyuli eyongezelelweyo yonikezelo lwamandla epoe inokudityaniswa kumandla e-AP ngokutshintsha? Enyanisweni, kunokwenzeka. Inokuthathwa kuphela njengokusebenzisa i-4578 yeenyawo zentambo yenethiwekhi kwindawo ye-100M yenethiwekhi ukuhambisa amandla. Oko kukudibanisa umdibanisi we-POE (owaziwa ngokuba ngumbane we-POE) phakathi kokutshintsha kunye ne-AP, kodwa isiseko sixhomekeke ekubeni i-AP yakho isekela ukufumana umbane we-POE.

PoE tshintsha imowudi yonikezelo lwamandla enye

Ke ukuba une-AP engenazingcingo efakwe kwisilingi, uninzi lwayo luyayixhasa. Esinye isiphelo yintambo yenethiwekhi evela kwi-network port, kwaye enye isiphelo yintambo yenethiwekhi kunye neplagi ye-DC, efakwe kwi-port yenethiwekhi ye-AP kunye ne-port yamandla. Yiyo leyo. Nangona kunjalo, kulo mzekelo, kukho iindlela ezimbini zokusebenzisa i-POE ukubonelela amandla kwi-AP, kodwa i-48V eyongezelelweyo kwi-12V ye-POE splitter yongezwa kwi-AP.

Olu hlobo lwe-POE eqhekezayo yi-DC48V ukuya kwi-12V yesiguquli. Esinye isiphelo yintambo yenethiwekhi ukusuka kwi-network port ukuya kwi-POE, kwaye enye isiphelo yintloko yentambo yenethiwekhi kunye neplagi yamandla ye-DC, efakwe kwi-port yenethiwekhi ye-AP kunye ne-port yamandla.

PoE tshintsha indlela yonikezelo lwamandla amabini

Esinye isiphelo yiplagi yentambo yenethiwekhi, efakwe kwiplagi yodonga lwenethiwekhi ekhokelela kwi-AP. Iyafana naleyo ikwindlela yokuqala. Ukuba i-manual ayibhali ukuxhasa i-POE, ngokuqhelekileyo ayixhaswanga, kuba ukongeza le nxalenye yesiphaluka kufuna amashumi e-yuan. Iindleko. Xhuma intambo yenethiwekhi ukusuka kwitshintshi kunye ne-adapter yamandla ye-12V kwi-AP yakho, kodwa akukho nxalenye ye-transformer; uxhulumaniso lweDATHA lunokudityaniswa kwi-AP. Ukuba ixhaswa, imodyuli ye-48V ye-POE yonikezelo lwamandla inokudityaniswa phakathi kokutshintsha kunye ne-AP. Kukho izibuko ezimbini zenethiwekhi kwimodyuli yonikezelo lwamandla e-POE, kwaye iswitshi eqhagamshelwe kwi-DATA ibhaliwe. I-port ye-DATA ifakwe kwintambo yenethiwekhi ukusuka kutshintshi, kwaye i-DATA & POWER port ifakwe kwintambo yenethiwekhi ekhokelela kwi-AP. Emva koko intambo yenethiwekhi ekupheleni kwe-AP ixhunywe kwi-POE yokuhlukanisa okanye i-splitter, ekwaxhaswa nayo, kodwa ukunikezelwa kwamandla kuzinzile kwaye ubude bentambo yenethiwekhi buvunyelwe ukufikelela kwiimitha ezili-100 okanye ngaphezulu. Le ndlela inexabiso eliphantsi kakhulu, kodwa ukuba umgangatho wentambo yenethiwekhi uhlupheke kakhulu okanye ude kakhulu, uya kubangela ukunikezelwa kwamandla okwaneleyo kwi-AP.

Iingcebiso zokutshintsha kwePOE

Indlela yokuqala iyabiza kwaye idinga i-AP ukuxhasa ukunikezelwa kwamandla kaPoe. Ukuba awuyixhasi, awukwazi ukusebenzisa le ndlela yoqhagamshelwano. Kungenjalo, kulungile ukuba ixhotyiswe ngokubhaqwa okuzenzekelayo kwesixhobo esifumana amandla. Ukuba imodyuli ye-POE inyanzelekile ukuba inikeze amandla, iya kutshisa i-AP. Ngokubanzi, eyona ilula idibanisa kwimarike yile inesiphelo esinye. Elinye izibuko lothungelwano kunye nelinye i-DC female connector. Ingaba iyayixhasa le ncwadana iya kubhalwa (okanye ubuze umrhwebi), umzekelo, kubhaliwe ukuba ixhasa i-IEEE 802.

I-port female port ye-DC kwi-combiners ifakwe kwi-adapter yamandla ye-AP, kwaye ifanelekile kuphela kwi-100M yenethiwekhi yendawo. Ukuba idibaniswe kwinethiwekhi yeGigabit, iya kutshisa isixhobo. Le ndlela ayiyonxalenye ye-POE eqhelekileyo. Ukuba awuyiplagi eludongeni, kuya kufuneka uthenge olo hlobo lwesihlanganisi semodyuli. Abanye abavelisi baya kuba livila kwaye babhale nje ukuba baxhasa unikezelo lwamandla lwe-POE. 3af okanye IEEE 802.3at, okuthetha ukuba bayayixhasa.
