Simba pamusoro peEthernet (PoE) inyanzvi yekugadzira magetsi yakavakirwa panharaunda yenharaunda network (LAN), iyo inogona kuendesa simba uye data kune mudziyo kuburikidza netiweki tambo muEthernet. Kushandiswa kweiyi tekinoroji kunogona kuderedza zvakanyanya mari yekushandisa uye kuchengetedza nguva yekushandisa. Parizvino, kune maswiti akasiyana-siyana anoenderana nehunyanzvi hwePoE pamusika, kunyanya PoE switch, PoE + switch, uye PoE ++ switch. Ndokumbira uteedzere.JHA TECHkuti unzwisise musiyano uripo pakati pema switch aya.

Chii chinonzi PoE? Chii chinonzi PoE switch?

PoE (inonziwo IEEE 802.3af standard) chiyero chitsva chakavakirwa paSimba rePower over Ethernet rakashambadzirwa neIEEE 802.3 boka rinoshanda muna 2003. Chiyero chacho chinoti mudziyo wekugamuchira simba (PD), wakaita sefoni yeVoIP. , inongoda kushandisa maviri akamonyoroka eiyo tambo yetiweki kuti ishandiswe panguva yekugamuchira simba, uye mashandisiro ayo ePoE simba anogona kusvika kusvika. 12.95W.

PoE switch, inonziwo PoE magetsi emagetsi switch, chishandiso chakavakirwa paPoE tekinoroji. Iyo switch iyo inogona kupa simba uye data kutapurirana kune inogashira terminal panguva imwe chete kuburikidza netiweki tambo, uye ndeyemagetsi emagetsi terminal zvishandiso (PSE). Kazhinji, poE switch inoenderana ne802.3af standard inogona kutsigira huwandu hwemagetsi e15.4W pachiteshi, uye magetsi emagetsi ari 44V-57V. Mhepo yekupinza yePoE mudziyo yakabatana nePoE switch iyi ndeye 37V-57V.

Chii chinonzi PoE+? Chii chinonzi PoE + switch?

PoE+ (inonziwo IEEE 802.3af chiyero), sekusimudzira kuPoE tekinoroji, chiyero chehunyanzvi chePoE chakaburitswa muna 2009. Nekushandiswa kwakapararira kwehunyanzvi hwePoE, mamwe maturusi ekugamuchira simba akadai seasina waya AP anoda simba rakawanda. kupfuura 12.95W. Kugadzirisa dambudziko iri, boka rekushanda reIEEE 802.3 rakaburitsa tekinoroji yePoE+ yakagadzirirwa kupa simba repamusoro kumidziyo.

Iyo PoE + switch yakafanana nePoE switch yatataura pamusoro, uye inopawo simba kuPoE terminal mudziyo kuburikidza netiweki tambo. Musiyano ndewekuti huwandu hwemagetsi echiteshi chega chega chePoE + switch ndeye 30W, uye magetsi emagetsi ari 50V-57V. Iyo yakawanda yemagetsi inogamuchirwa nemagetsi inogamuchira mudziyo inogona kuwedzerwa kusvika 25.5W, uye voltage inogona kuwedzerwa kusvika 42.5V-57V.

Chii chinonzi PoE++? Chii chinonzi PoE ++ switch?

Nekuenderera mberi kwekusimudzira kwemusika wekushandisa wePoE, iyo IEEE 802.3 standard yakawedzera iyo IEEE 802.3bt standard. Panguva ino, teknolojia yePoE ++ yakabudawo. Pasi peIEEE 802.3bt chiyero, PoE ++ tekinoroji ine marudzi maviri emapazi. Imwe teknolojia yePoE ++ inonzi Type3 inogona kushandiswa nembiri kana ina dzakamonyoroka dzetambo imwechete yetiweki, uye inogona kupa kusvika ku51W yemagetsi ekuisa kune mudziyo unogamuchira simba.Imwe inyanzvi yeType4PoE ++, inoda kupa simba kuPoE. terminal mudziyo kuburikidza ese maviri maviri etiweki tambo, uye simba rekuisa rinogona kusvika 71W. Pamusoro pezvo, kune tekinoroji yePoE yakavakirwa pachiyero cheIEEE 802.3bt chinonzi UPOE (simba repasi rose pamusoro peEthernet). Iyi tekinoroji inoenderana neCisco, uye maitiro ekushanda akafanana neType3PoE tekinoroji (PoE ++), uye simba rekuisa rinogona kupihwa kune yekugamuchira yekupedzisira mudziyo i51W. Naizvozvo, vamwe vanhu vari muindasitiri vanozotorawo UPOE sePoE ++.

Sekusimudzira kune PoE switch uye PoE + switch, PoE ++ switch inogona kupa kusvika ku60W yemagetsi emagetsi pachiteshi cheType3PoE ++ switch, uye 100W yeType4. Tarisa patafura pazasi kuti uone iwo chaiwo maparamendi ePoE ++ switch uye mamwe maviri marudzi ekuchinja.
