Iiswitshi ziqhele ukusetyenziswa kwiiprojekthi zangoku ezibuthathaka, ngakumbiIiswitshi zePOE.I-POE ikwabizwa ngokuba yinkqubo yendawo yendawo esekelwe kwinethiwekhi (POL, Power over LAN) okanye i-Active Ethernet (Active Ethernet), ngamanye amaxesha ibizwa ngokuba yi-Power over Ethernet.Le yinkcazo esemgangathweni yamva nje yokuhambisa idatha kunye namandla ombane usebenzisa iintambo ezikhoyo zothumelo lwe-Ethernet, kwaye igcina ukuhambelana neenkqubo ezikhoyo ze-Ethernet kunye nabasebenzisi.Ke, sikhetha njani iswitshi yePOE?

1. Qwalasela amandla esixhobo sakho

Ngokuhambelanayo khetha i-PoE switch enamandla amakhulu.Ukuba amandla esixhobo sakho angaphantsi kwe-15W, ngoko khetha i-PoE switch exhasa umgangatho we-802.3af.Ukuba amandla amakhulu kune-15W, khetha ukutshintshwa kwamandla aphezulu kunye ne-802.3at standard.Okwangoku, iiswitshi ezininzi ze-PoE zixhasa zombini kunye ne-af, ngoko ke nikela ingqalelo ngakumbi xa uthenga.

2. Izibuko elibonakalayo

Okokuqala, kuyimfuneko ukugqiba inani lonxibelelwano lokutshintsha, inani lee-fiber optical port, ulawulo lwenethiwekhi, isantya (10/100/1000M) kunye neminye imiba.Okwangoku, ujongano kwimarike ubukhulu becala 8, 12, 16, kunye namachweba angama-24.Kukho ngokubanzi enye okanye ezimbini izibuko ifayibha optical, kwaye kufuneka unikele ingqalelo ukuba izibuko optical yi 100M okanye 1000M.Kuxhomekeke kwimeko.

Ukutshintsha kwe-PoE ngokuqhelekileyo kusetyenziselwa ukudibanisa iitheminali ezinamandla kwaye zisetyenziswa njengokutshintsha ukufikelela.Qwalasela inani lamazibuko ombane we-PoE axhaswa lutshintsho ngokwenani lezixhobo zetheminali ezinikwe amandla.Ukongeza, kuyafuneka ukuba kuqwalaselwe ubungakanani bezinga eliphezulu ekufuneka izibuko lixhase ngokuhambelana ne-terminal ene-powered kunye neemfuno zokwenyani.Ngokomzekelo, ukuba i-port ye-AP yi-Gigabit kwaye isebenzisa i-11AC okanye i-dual-band, ukufikelela kwe-Gigabit kunokuqwalaselwa.

3. Iiparamitha zokubonelela ngombane

Khetha iswitshi efanelekileyo ngokweprotocol yonikezelo lwamandla (efana ne-802.3af, 802.3at okanye i-PoE engeyiyo eyomgangatho) exhaswa yi-terminal ene-powered (AP okanye i-IP camera).Iprothokholi yonikezelo lwamandla e-PoE exhaswa sisitshixo kufuneka ihambelane netheminali yombane.Zininzi iingozi zokhuseleko ezinokubakho kwiiswitshi zePoE ezingekho mgangathweni.Kucetyiswa ukuba uzame ukukhetha izixhobo ezisemgangathweni zokutshintsha kwe-48V PoE.

4. Iskimu socingo

Abasebenzisi banokuthelekisa kwaye babale iindleko ze-terminal yonikezelo lwamandla ombane wengingqi kunye neendleko zokusebenzisa iswitshi ye-PoE yobonelelo lombane.Okwangoku, umgama wonikezelo lwamandla wokutshintsha kwe-PoE ungaphakathi kweemitha ezili-100.Akukho zithintelo zoyilo, ezinokuthi zonge malunga ne-50% yeendleko zizonke.Iingcingo ezingaphakathi kweemitha ezili-100 zinokunweba ngokuguquguqukayo uthungelwano ngaphandle kokuthintelwa kukucwangciswa kweentambo zombane.Hang i-wireless APs, iikhamera zenethiwekhi kunye nezinye izixhobo ze-terminal kwiindonga eziphakamileyo okanye iisilingi zokwandiswa okuguquguqukayo, i-wiring elula, kunye nenkangeleko enhle.

5. Ukuthengiswa kwangaphambili kunye nenkxaso yobugcisa emva kokuthengisa

Khetha abarhwebi abathembekileyo ukuba bafumane ukuthengisa kwangaphambili kunye neenkonzo emva kokuthengisa

JHA,umenzi ophezulu e Shenzhen, igxile kwi-R&D kunye nemveliso yeIiswitshi zePoE,utshintsho lwamashishini, isiguquli semidiyakunye nezinye izixhobo zonxibelelwano,wamkelekile ukuba uthethe
