M'nthawi yamakono ya digito, ma switch a Ethernet amatenga gawo lofunikira pakukhazikitsa ndi kusunga maukonde opanda msoko. Kumvetsetsa mawonekedwe ndi maubwino awo ndikofunikira, makamaka kwa anthu omwe akufuna kuwongolera magwiridwe antchito a netiweki. Nkhaniyi ikufuna kupereka chiwongolero chokwanira pa ma switch a Ethernet ndi momwe angathandizire kudalirika kwa maukonde. Kusintha kwa Efaneti ndi chipangizo chomwe chimalumikiza zida zingapo, monga makompyuta, maseva, ndi osindikiza, ku netiweki yapafupi (LAN) kapena netiweki yadera lalikulu (WAN). Imakhala ngati chigawo chapakati chomwe chimathandizira kulumikizana pakati pa zidazi potumiza mapaketi a data kumalo oyenera.

Kusintha kwa PoE kumagwira ntchito ngati chosinthira, ndipo chitha kugwiritsidwanso ntchito ngati chosinthira nthawi zonse. Komabe, ikagwiritsidwa ntchito ngati masinthidwe wamba, mtengo wa switch ya PoE sunakulitsidwe, ndipo ntchito zamphamvu zosinthira PoE zimawonongeka. Chifukwa chake, pali zochitika pomwe palibe chifukwa choperekera mphamvu ya DC ku chipangizo cholumikizidwa ndikungofunika kutumiza deta. , Ndibwino kuti musankhe kusintha kwanthawi zonse, ndipo ngati simukusowa kutumiza deta komanso magetsi, ndi bwino kusankha kusintha kwa PoE. Ngati mukufuna kusintha chosinthira wamba kukhala chosinthira cha PoE, ngati muphatikiza chosinthira wamba kukhala chosinthira cha PoE, magetsi ndi kutumizirana data sizingachitike nthawi imodzi.

Kusintha kwa PoE ndi mtundu watsopano wakusintha kwamitundu yambiri. Chifukwa cha kufalikira kwa ma switch a PoE, anthu amamvetsetsa pang'ono ma switch a PoE. Komabe, anthu ambiri amaganiza kuti ma switch a PoE amatha kupanga mphamvu pawokha, zomwe sizowona. Kusintha kwamagetsi kwa PoE nthawi zambiri kumatanthauza kusintha kwa PoE komwe kumapereka mphamvu ku zida zina kudzera pa chingwe cha netiweki popanda kutaya mphamvu zotumizira deta. Ndiye kodi kusintha kwa PoE kungagwiritsidwe ntchito ngati chosinthira nthawi zonse? Kusintha kwa PoE ndikusintha kokhala ndi magwiridwe antchito a PoE omwe amatha kulumikizidwa ndi switch yokhazikika.

1.Sturdiness Industrial switches amapangidwa ndikupangidwa pogwiritsa ntchito zigawo zamagulu a mafakitale. Zigawozi zimasankhidwa makamaka kuti zipirire malo ovuta ndikupereka ntchito zapamwamba ngakhale pansi pa zovuta. Kugwiritsa ntchito mafakitale ...

Ukadaulo wa Power over Ethernet (POE) wasintha momwe timayatsira zida zathu, kutipatsa kusavuta, kuchita bwino komanso kupulumutsa ndalama. Mwa kuphatikiza mphamvu ndi kutumiza kwa data pa chingwe cha Ethernet, POE imachotsa kufunikira kwa chingwe chamagetsi chosiyana, kupanga ...

Kuyambitsa ukadaulo waposachedwa wapaintaneti, ma switch a JHA Web Smart Series compact Ethernet. Masinthidwe opulumutsa malowa komanso otsika mtengo adapangidwa kuti akwaniritse zosowa zomwe zikukula za Industrial Ethernet. Kusintha kwa JHA Web Smart Series ...

M'nkhaniyi, tikambirana zoyambira zosinthira maukonde ndikuwunika mawu ofunikira monga Bandwidth, Mpps, Full Duplex, Management, Spanning Tree, ndi Latency. Kaya ndinu oyambira pa intaneti kapena wina yemwe akufuna kukulitsa chidziwitso chanu, nkhaniyi ...

M’dziko lamakono lamakono, teknoloji ikupita patsogolo mofulumira. Pamene chifuniro cha anthu cholumikizira ma netiweki moyenera komanso chosavuta chikupitilira kukula, zida monga ma switch a POE zakhala zofunikira. Ndiye kusintha kwa POE ndi chiyani komanso phindu lotani ...

1. PoE yosakhala wamba ndi PoE yokhazikika Kwa PoE yokhazikika yomwe imagwirizana ndi IEEE 802.3af/at/bt ndipo imakhala ndi ndondomeko yogwirana chanza. PoE yosakhala wamba ilibe protocol yogwirana chanza, ndipo imapereka magetsi a 12V, 24V kapena 48V DC okhazikika. PoE yokhazikika po...

Optical module ndiye chowonjezera chachikulu cha njira yolumikizirana yolumikizirana ndipo imagwira ntchito yofunika kwambiri pakulumikizana kwa fiber. Iwo makamaka anamaliza photoelectric kutembenuka ntchito. Ubwino wa module optical umatsimikizira kufala kwa ...
