Hamwe niterambere ryiterambere ryiterambere rya tekinoroji ya PoE, abahindura PoE kuri ubu bari mubyiciro bikuze cyane, ariko, kubera isoko ryikurikiranabikorwa ryubu munsi yigitutu cyibiciro, ubwiza bwibikoresho byatoranijwe bya PoE cyangwa insinga biri hasi cyane, cyangwa igishushanyo mbonera ubwacyo ni bidafite ishingiro, bizavamo imirimo iremereye cyane yo kubungabunga imishinga itanga amashanyarazi. Umushinga wo gukurikirana imiyoboro itandukanye nu rusobe rusanzwe rwinjizwamo insinga, ubwinshi bwo kohereza amakuru ni bwinshi, imbaraga ni nyinshi, kandi bisaba akazi kadahagarara amasaha yose, bityo rero kubona amashanyarazi ya PoE adahagaze. Ariko amashanyarazi ya POE mubyukuri ntahungabana? Reka tumenye uburyo abahindura PoE bashobora guhuzwa neza kandi ni izihe nyungu z'umutekano zo guhinduranya PoE? Reka turebe!

Nigute ushobora kwemeza ihuza rihamye rya PoE switch？

① Koresha uburyo busanzwe bwa PoE. Guhindura PoE idasanzwe ntabwo ifite IEEE802.3af cyangwa IEEE802.3at protocole. Hatitawe ku kuba igikoresho cya terefone gishyigikira amashanyarazi ya PoE, guhatira amashanyarazi 48V byangiza ibikoresho byanyuma. Kubwibyo, gukoresha ikoreshwa rya PoE risanzwe kugirango uhuze nintambwe yambere yo kwemeza imikorere ihamye ya sisitemu.

. Koresha umugozi wujuje ibyangombwa. Irinde kugura imigozi idasanzwe ya patch yujuje ubuziranenge. Kuberako bidakozwe muburyo bukwiranye nibisabwa numuyoboro usanzwe, ibyuma byambaye umuringa / aluminium / icyuma birashobora kubaho. Kubwibyo, kurwanya insinga zumuyoboro bizaba binini kandi ntibikwiriye gutanga amashanyarazi ya PoE.

Kugena ingufu zikoreshwa mubikoresho bya terefone. Ibipimo bitandukanye bya PoE byahinduwe bifite imbaraga zitandukanye zo gusohora, nka: IEEE802.3af isanzwe ya POE irashobora gutanga ingufu kubikoresho bifite ingufu nyinshi zitarenza 15.4W; Ihinduka rya PoE rihuye na IEEE802.3at isanzwe irashobora gutanga amashanyarazi kubikoresho bitagikoreshwa cyane bitarenze 30W. Ukurikije intera yoherejwe hamwe nigihombo cyibintu, ingufu nyinshi zishobora gutangwa zishobora kuba nke.

Sobanura umubare wibikoresho bya terefone. Ukurikije ibipimo bya IEEE802.3af, niba amashanyarazi yose ya PoE yumurongo wa 24 wicyambu cya PoE agera kuri 370W, irashobora gutanga ibyambu 24 (370 / 15.4 = 24),; Ariko niba ibarwa ukurikije igipimo cya IEEE802.3at kugirango icyambu kimwe gitange amashanyarazi ntarengwa ya 30W, icyarimwe, irashobora gutanga amashanyarazi gusa ku byambu 12 kuri byinshi (370/30 = 12).

Menya intera yoherejwe. Intera itanga amashanyarazi ya PoE ihinduka igenwa nintera yo kohereza ibimenyetso byamakuru. Iyo igipimo cyo kohereza ari 100Mbps, intera ntarengwa ibimenyetso byamakuru bishobora koherezwa ni 100m. Kubwibyo, urebye intera yoherejwe hashingiwe ku gipimo cyo kohereza ni kimwe mu bintu byemeza ihuza rihamye rya PoE.

Afite IETF RFC2544 isanzwe. Ibipimo ngenderwaho birashobora gutanga serivisi yo guhagarika ibipimo ngenderwaho kugirango igerageze kwinjiza ibikoresho byurusobekerane rwibikoresho, umubare wibikoresho bisubira inyuma, igipimo cyo gutakaza paki no gutinza imikorere, no gukurikirana ihuza rihamye rya PoE.
