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): Guhindura Ethernet, router, hubs, 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 ryikurikiranabikorwa, ubwiza bwa PoE yahinduwe cyangwa insinga zikoreshwa ziri hasi cyane, cyangwa igishushanyo mbonera ubwacyo nticyumvikana, bikavamo 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. Ingaruka yibanze cyane: Mubisanzwe, PoE switch izatanga ingufu kuri AP nyinshi icyarimwe.Kunanirwa kwose kwa POE itanga amashanyarazi ya switch bizatera ibikoresho byose kunanirwa gukora, kandi ibyago birakabije.
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 ushobora guhitamo icyerekezo cya PoE?
1. Ni imbaraga zingahe zisabwa kugirango ibikoresho bikoreshwe: Guhindura PoE ikoresha ibipimo bitandukanye, kandi ingufu zisohoka zizaba zitandukanye, urugero: IEEE802.3af ntirenza 15.4W, kubera gutakaza insinga zohereza, irashobora gutanga ibikoresho hamwe gukoresha ingufu zitarenze 12.95W zikoreshwa na.PoE ihindura yujuje ubuziranenge bwa IEEE802.3at irashobora gutanga ingufu kubikoresho bifite ingufu zitarenze 25W.
2. Nibikoresho bingahe bishobora gukoreshwa: Ikimenyetso cyingenzi cyerekana PoE ni imbaraga zose zitangwa na PoE.Ukurikije ibipimo bya IEEE802.3af, niba ingufu zose za PoE zihinduranya ibyambu 24 bya PoE igera kuri 370W, noneho irashobora gutanga ibyambu 24 (370 / 15.4 = 24), ariko niba ari amashanyarazi yicyambu kimwe ukurikije IEEE802 .3ibisanzwe Imbaraga zibarwa kuri 30W, kandi mugihe kimwe, irashobora gutanga ingufu kubicyambu 12 gusa (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.
