Simba rePOE rinowanikwa kuburikidza netambo yetiweki, uye tambo yetiweki inoumbwa nemapaya mana eakamonyoroka maviri (8 core waya), saka masere epakati waya mutambo yetiweki ndiyo PoE.chinjakupa data uye simba rekufambisa midhiya yemudziyo unogamuchira. Parizvino, PoE switches inopa kutapurirana inoenderana DC simba kune inogashira End zvishandiso kuburikidza netatu PoE magetsi emagetsi modes: Mode A (end-SPAN end crossover), mode B (Mid-Span yepakati crossover) uye 4-peya.
• Mode A PoE simba rekupa maitiro
Modhi A ndeyekupedzisira-nguva. Mune iyi modhi, iyo PoE switch inopa simba kune inogashira End mudziyo kuburikidza ne1, 2, 3, uye 6 waya, uye zvakare inotumira data. 1 uye 2 materminal akanaka, uye 3 ne6 materminal asina kunaka.
• Mode B PoE magetsi ekupa maitiro
Mode B ndiyo yepakati-Span modhi. Mune iyi modhi, iyo PoEchinjainopa simba kumudziyo wekugamuchira kuburikidza ne4, 5, 7, uye 8 waya. Kana yaiswa ku10BASE-T uye 100BASE-T Ethernet, 4, 5, 7, 8 mitsetse inongofambisa kufambisa kwemagetsi, haizoite kutapurirana kwedata, saka tsoka ina dzinonziwo idle tsoka. Apo 4, 5 seye electrode yakanaka, 7, 8 se electrode yakaipa.
• Iyo 4-pairi PoE magetsi ekugadzirisa maitiro
Mune iyi modhi, iyo PoEchinjaichapa simba kumudziyo wekugamuchira kuburikidza nemitsara yose, apo 1, 2, 4, uye 5 ari materminals akanaka, uye 3, 6, 7, uye 8 inzvimbo dzisina kunaka.
Izvo zvinofanirwa kucherechedzwa kuti iyo PoE magetsi ekupa maitiro inotarwa neiyo magetsi emagetsi mudziyo, uye iyo PoEchinjauye PoE simba rekupa (simba jekiseni) rinogona kushandiswa sechishandiso chekupa magetsi kuita simba uye kuendesa data kune inotambira mudziyo. Sechishandiso chekupa magetsi, iyo PoEchinjakazhinji inoshandisa mode A yekugovera magetsi. Kazhinji, jekiseni rePoE rinoshandiswa semudziyo wepakati kubatanidza iyo isiri-standard PoEchinjauye mudziyo wekugamuchira. Inogona chete kutsigira PoE magetsi emagetsi mode mumodhi B.
PoE magetsi emagetsi kureba: Nekuti simba uye masaini etiweki anokanganiswa nyore nekupokana uye capacitance kana ichifambiswa pane network tambo, zvichikonzera kudzikisira kwechiratidzo kana kusagadzika magetsi, kureba kwekufambisa kwetambo yetiweki kunogumira, uye kureba kwekufambisa kure kunogona chete. kusvika 100 metres. PoE simba rekushandisa rinowanikwa kuburikidza netiweki tambo, saka kureba kwayo kwekutapurirana kunokanganiswa netambo yetiweki, uye kureba kwekutapurirana kureba kuri 100 metres. Nekudaro, kana iyo PoE extender ikashandiswa, iyo PoE yemagetsi renji inogona kuwedzerwa kusvika pahupamhi hwemamita 1219.
PoE magetsi ekupa modhi inounzwa mune zviri pamusoro apa, sekunge iyochinjadzakatevedzana zvigadzirwa zvataurwa pamusoro apa, ivo vakakurumbira kutaurirana zvigadzirwa muShenzhen HDV Phoelectron Technology LTD., senge: Ethernetchinja, Fiber Channelchinja, Ethernet Fiber Channelchinja, zvichingodaro, shanduko dziri pamusoro dzinogona kushandiswa mumamiriro akasiyana-siyana, kupa mamwe sarudzo kune vashandisi vane zvinodiwa zvakasiyana, kugamuchirwa kuti vauye kuzonzwisisa, isu tichapa yakanakisa mhando sevhisi.
