Hamwe niterambere ryihuse rya terefone ya IP, imiyoboro ya LAN itagikoreshwa, hamwe no kugenzura imiyoboro mumyaka yashize, urwego rwa tekiniki rugenda rwiyongera, kandi inkunga ya tekiniki itangwa nababikora iragenda irushaho kuba yuzuye kandi itunganijwe. Mu guhanahana tekinike, mubitiranya cyane namasosiyete yubwubatsi harimo ikibazo cyo gutanga amashanyarazi POE.
Ikibazo 1: Ikoranabuhanga rya PoE ni iki?
PoE (Imbaraga Zirenga Ethernet) bivuga ibikorwaremezo bya Ethernet Cat.5 bihari ibikorwa remezo bya cabling nta gihindutse, kubintu bimwe na bimwe bishingiye kuri IP (nka terefone ya IP, umurongo wa LAN utagira aho uhurira na AP, kamera y'urusobe Etc.) Mugihe wohereza amakuru, irashobora kandi tanga amashanyarazi ya DC kubikoresho nkibi. Ikoranabuhanga rya PoE rirashobora kurinda umutekano wa kabili isanzwe ihari mugihe ikora imikorere isanzwe y'urusobe rusanzwe, bikagabanya cyane ibiciro.
Sisitemu yuzuye ya PoE ikubiyemo ibice bibiri: ibikoresho byo gutanga amashanyarazi (PSE, ibikoresho byo gutanga amashanyarazi) nibikoresho byakira amashanyarazi (PD, ibikoresho bikoreshwa).
Ibikoresho byo gutanga amashanyarazi (PSE): EthernetGuhindura, Routers, hub, cyangwa ibindi bikoresho byo guhinduranya imiyoboro ishyigikira POE
Igikoresho cyakira ingufu (PD): Umushinga wo gukwirakwiza simusiga ni AP idafite umugozi.
Ikibazo 2: Amashanyarazi ya PoE arahagaze neza?
Urebye muburyo bwa tekiniki, tekinoroji ya PoE yateye imbere mumyaka kandi ubu iri mubyiciro bikuze cyane. Ariko, kubera umuvuduko wibiciro byisoko ryo kugenzura, ubwiza bwa PoEGuhinduracyangwa insinga zikoreshwa ziri hasi cyane, cyangwa igishushanyo mbonera ubwacyo nticyumvikana, bivamo akazi karemereye cyane kumishinga ukoresheje amashanyarazi ya PoE. Reba neza.
Kubijyanye no kohereza amakuru manini cyane, imbaraga nyinshi, hamwe nibisabwa kumurimo 24/7 udahagarara, gukoresha ibikoresho bya PoE byizewe neza hamwe ninsinga ni garanti yumutekano wa sisitemu yose.
Ikibazo 3: Ni izihe nyungu zo gukemura amashanyarazi PoE?
1. Koroshya insinga no kuzigama amafaranga yumurimo
Umuyoboro wa neti wohereza amakuru n'imbaraga icyarimwe. PoE ikuraho ibikenerwa mumashanyarazi ahenze nigihe gitwara cyo gushiraho amashanyarazi, kuzigama amafaranga nigihe.
2. Umutekano kandi woroshye
Ibikoresho bitanga amashanyarazi bizatanga ingufu gusa kubikoresho bigomba gukoreshwa. Gusa mugihe ibikoresho bigomba gukoreshwa bigomba guhuzwa, hazaba voltage kumurongo wa Ethernet, bityo bikureho ibyago byo kumeneka kumurongo. Abakoresha barashobora kuvanga neza ibikoresho byumwimerere nibikoresho bya PoE kumurongo, kandi ibyo bikoresho birashobora kubana ninsinga zisanzwe za Ethernet.
3. Korohereza imiyoborere ya kure
Kimwe no kohereza amakuru, PoE irashobora gukurikirana no kugenzura igikoresho ukoresheje uburyo bworoshye bwo gucunga imiyoboro (SNMP). Iyi mikorere irashobora gutanga imirimo nko guhagarika ijoro no gutangira kure.
Ikibazo cya 4: Ni izihe ngaruka cyangwa ibibi bya tekinoroji ya PoE itanga amashanyarazi mubikorwa bya injeniyeri?
1. Imbaraga zidahagije, imbaraga zakira amaherezo ntishobora gutwarwa: 802.3af isanzwe (PoE) imbaraga zisohoka ni 15.4W. Kubikoresho-bikomeye-imbere-ibikoresho, imbaraga zisohoka ntizishobora kuzuza ibisabwa.
2. Ibyago byibanda cyane: Muri rusange, PoEhinduraizatanga ingufu kuri AP nyinshi icyarimwe. Kunanirwa kwose kwa POE amashanyarazi module yahindurabizatera ibikoresho byose kunanirwa gukora, kandi ibyago biribanze cyane.
3. Ibikoresho bihanitse hamwe nigiciro cyo kubungabunga: Ugereranije nubundi buryo bwo gutanga amashanyarazi, tekinoroji ya PoE itanga amashanyarazi izongera imirimo yo kubungabunga ibicuruzwa nyuma yo kugurisha. Mu rwego rwumutekano n’umutekano, ituze n’umutekano byo gutanga amashanyarazi atandukanye nibyiza cyane.
Ikibazo 5: Nigute wahitamo PoEhindura?
1. Ni imbaraga zingahe zisabwa kugirango ibikoresho bigerweho: PoEGuhindurakoresha ibipimo bitandukanye, kandi ingufu zisohoka zizaba zitandukanye, kurugero: IEEE802.3af ntirenza 15.4W, kubera gutakaza insinga zogukwirakwiza, irashobora gutanga ibikoresho bikoresha amashanyarazi bitarenze 12.95W ikoreshwa na. PoEGuhinduraibyo byubahiriza IEEE802.3ibisanzwe birashobora gutanga ingufu kubikoresho bifite ingufu zitarenze 25W.
2. Nibikoresho bingahe bishobora gukoreshwa: Ikimenyetso cyingenzi cya PoEGuhindurani imbaraga zose zo gutanga amashanyarazi PoE. Munsi ya IEEE802.3af, niba imbaraga zose za PoE zicyambu cya 24hinduraigera kuri 370W, noneho irashobora gutanga ibyambu 24 (370 / 15.4 = 24), ariko niba ari icyambu kimwe gitanga amashanyarazi ukurikije igipimo cya IEEE802.3at Imbaraga zibarwa kuri 30W, kandi mugihe kimwe, irashobora gusa gutanga ingufu ku byambu 12 byinshi (370/30 = 12).
3. Ukeneye umubare wintera, waba uzana icyambu cya fibre, hamwe cyangwa udafite imiyoboro ya neti, umuvuduko (10/100 / 1000M).
Ikibazo 6: Intera yoherejwe neza mumashanyarazi ya PoE? Ni ubuhe butumwa bwo guhitamo insinga z'urusobe?
Intera yoherejwe neza ya POE itanga amashanyarazi ni metero 100. Birasabwa gukoresha ubwoko butanu bwinsinga zumuringa.
Umuyoboro w'amashanyarazi wa POE urasaba iki kibazo kuba ikibazo gusa mubihugu nk'Ubushinwa ndetse no mubindi bihugu aho ibicuruzwa mpimbano n'ibicuruzwa bihendutse byiganje. Ntabwo ari ikibazo mubihugu byinshi byateye imbere. POE IEEE 802.3af isanzwe isaba ko imbaraga zisohoka zicyambu cya PSE zisohoka ari 15.4W cyangwa 15.5W. Igikoresho cya PD cyakira imbaraga nyuma yo kohereza metero 100 kigomba kuba munsi ya 12.95W. Ukurikije 802.3af isanzwe ifite agaciro ka 350ma, kurwanya insinga ya metero 100 bigomba kuba (15.4-12.95W) / 350ma = 7 oms cyangwa (15.5-12.95) / 350ma = 7.29 oms.
Umuyoboro usanzwe usanzwe wujuje iki gisabwa. IEEE 802.3af poe itanga amashanyarazi ubwayo yapimwe numuyoboro usanzwe. Impamvu ituma imiyoboro ya POE itanga imiyoboro isabwa ni ukubera ko insinga nyinshi zumuyoboro ku isoko ari insinga zidasanzwe zisanzwe, zidakozwe muburyo bukurikije ibisabwa ninsinga zisanzwe. Ibikoresho by'insinga zidasanzwe zisanzwe ku isoko zirimo ibyuma bikozwe mu muringa, aluminiyumu y'umuringa, hamwe n'icyuma cyambaye umuringa. Intsinga zumuyoboro zifite indangagaciro nini zo guhangana kandi ntizikwiriye gutanga amashanyarazi ya POE. Amashanyarazi ya POE agomba gukoresha umugozi wumuringa utagira ogisijeni, ni ukuvuga umugozi usanzwe.
