PoE (Imbaraga hejuru ya Ethernet) bivuga imbaraga hejuru ya tekinoroji ya Ethernet yohereza icyarimwe imbaraga hamwe namakuru binyuze mumigozi igoramye. Ikoreshwa ryikoranabuhanga rirashobora kunoza neza ituze no guhuza imiyoboro, bityo ikaba itoneshwa nabantu. Kugeza ubu, hari porogaramu zitandukanye zishingiye ku ikoranabuhanga rya PoE ku isoko, nka Gigabit PoE ihindura, ibikoresho bya PoE, amashanyarazi ya PoE, n'ibindi.

Injiza ya PoE ni iki?

Injira ya PoE nayo yitwa midspan, charger ya PoE cyangwa adaptate ya PoE. Ihuza ibyuma bitari PoE hamwe nibikoresho bya PoE bikoresha ingufu (PD) binyuze mumigozi y'urusobe (nka Cat5eCat6Cat6a, nibindi) ikora. Ibi bikoresho mubisanzwe birakwiriye ahantu hagomba gushyirwaho ibikoresho bito bito ariko bikabura amashanyarazi. Iki gisubizo kigera ku ntera ishimishije mu guhuza imiyoboro ku giciro gito, ku buryo kwishyiriraho ibikoresho bitakibujijwe n’imiterere n’imiterere ihari.

Ibyiza byo gutera inshinge PoE bigaragarira cyane cyane mubice bikurikira:
* Byoroshye kwishyiriraho: Gusa uhuze amashanyarazi kubikoresho bya terminal ya PoE na switch kugirango utange imbaraga namakuru yohereza amakuru.
* Biroroshye kwaguka: Ibimenyetso byerekana amakuru byasohotse bitari PoE birashobora guterwa mumashanyarazi binyuze mumurongo wumuyoboro, kugirango utange imbaraga nogukwirakwiza amakuru kubikoresho bikoresha icyarimwe, bizana byinshi byoroshye. Kuri Igikoresho.
* Zigama amafaranga: Gukoresha amashanyarazi ya PoE birashobora gukomeza imiyoboro yububiko bwa mbere hashingiwe ku gukoresha neza ibikoresho byumwimerere, bityo bikabika cyane amafaranga yakoreshejwe.

Ubwoko bw'inshinge:

Amashanyarazi asanzwe ya PoE & Amashanyarazi adasanzwe

Amashanyarazi asanzwe ya PoE bivuga amashanyarazi akurikiza amahame yinganda za PoE (nka IEEE802.3af, IEEE802.3at cyangwa igipimo cya IEEE802.3bt). Ukurikije inganda za PoE zingana na 802.3af, 802.3at cyangwa 802.3bt, ibikoresho bitanga amashanyarazi PoE (PSE) hamwe nigikoresho gikoresha amashanyarazi bizahita biganira iyo bihujwe, kandi imishyikirano irashobora gutsinda mugihe gusa ibikoresho kumpande zombi bihuye uburyo bumwe. Nyuma yumushyikirano hagati yibi bikoresho byombi ugenda neza, igikoresho cyo gutanga amashanyarazi kizatanga ingufu kubikoresho bikoreshwa. Muri ubu buryo bwo gukora bwa tekinoroji isanzwe ya PoE, umutekano wibikoresho bya PoE urashobora kwizerwa cyane. Mubisanzwe, 802.3af, 802.3at cyangwa 802.3bt isanzwe itanga amashanyarazi ni 44-57V (DC).

Amashanyarazi adasanzwe ya PoE muri rusange yerekeza kubikoresho byamashanyarazi bidahuye nuburinganire bwinganda zose (nka IEEE802.3af, IEEE802.3at cyangwa IEEE802.3bt). Umuvuduko ukoreshwa wibikoresho bidasanzwe bya PoE ni 18-48V (DC). Niba agaciro ka voltage yibikoresho byombi bihujwe bidahuye, birashobora kwangiza burundu igikoresho.

12V / 24V / 48V Amashanyarazi

Amashanyarazi ya PoE arashobora kugabanywamo ubwoko butatu ukurikije ingufu ziva hanze: 12V, 24V na 48V. Mugihe uguze amashanyarazi ya PoE, ugomba gusuzuma niba voltage yibikoresho bya PoE ihujwe nayo bihuye.

Usibye ibyiciro bibiri byavuzwe haruguru byo gutanga amashanyarazi, Injira ya PoE irashobora kandi kugabanywa ukurikije umubare wibyambu bitandukanye, nkumuriro umwe w’amashanyarazi PoE hamwe n’ibyambu umunani bitanga amashanyarazi n'ibindi.
