Esikhathini samanje sedijithali, amaswishi e-Ethernet adlala indima ebalulekile ekusunguleni nasekugcineni ukuxhumeka kwenethiwekhi okungenazihibe. Ukuqonda izici nezinzuzo zabo kubalulekile, ikakhulukazi kubantu abafuna ukuthuthukisa ukusebenza kwenethiwekhi. Lesi sihloko sihlose ukuhlinzeka ngomhlahlandlela ophelele wokushintshwa kwe-Ethernet nokuthi bangakuthuthukisa kanjani ukwethembeka kwenethiwekhi. Ukushintsha kwe-Ethernet idivayisi exhumanisa amadivaysi amaningi, njengamakhompyutha, amaseva, namaphrinta, kunethiwekhi yendawo yendawo (LAN) noma inethiwekhi yendawo ebanzi (WAN). Isebenza njengehabhu elimaphakathi elivumela ukuxhumana phakathi kwalezi zisetshenziswa ngokuthumela amaphakethe edatha endaweni efanele.

Iswishi ye-PoE isebenza njengeswitch, futhi vele ingasetshenziswa njengeswitch evamile. Kodwa-ke, uma isetshenziswa njengokushintsha okujwayelekile, inani leswishi ye-PoE alikhuliswa, futhi imisebenzi enamandla yokushintsha kwe-PoE iyamoshwa. Ngakho-ke, kunezimo lapho singekho isidingo sokunikeza amandla e-DC kudivayisi exhunyiwe futhi udinga kuphela ukudlulisa idatha. , Kunconywa ukuthi ukhethe ukushintshwa okuvamile, futhi uma ungadingi ukudluliselwa kwedatha kuphela kodwa futhi nokunikezwa kwamandla, kungcono ukukhetha ukushintshwa kwe-PoE. Uma ufuna ukushintsha iswishi evamile ibe iswishi ye-PoE, uma uhlanganisa ngokuqondile iswishi evamile ibe iswishi ye-PoE, ukunikezwa kwamandla kanye nokudluliswa kwedatha ngeke kubonakale ngokugcwele ngesikhathi esifanayo.

I-PoE switch iwuhlobo olusha lweswishi enemisebenzi eminingi. Ngenxa yokusetshenziswa kabanzi kwamaswishi e-PoE, abantu banokuqonda okuthile ngokushintsha kwe-PoE. Kodwa-ke, abantu abaningi bacabanga ukuthi ukushintshwa kwe-PoE kungakhiqiza amandla ngokwawo, okungelona iqiniso. Iswishi ye-PoE yokuphakela amandla ngokuvamile ibhekisela ekushintsheni kwe-PoE enikeza amandla kwamanye amadivaysi ngentambo yenethiwekhi ngaphandle kokulahlekelwa amandla okudlulisa idatha. Ngakho-ke ingabe ukushintshwa kwe-PoE kungasetshenziswa njengokushintshwa okujwayelekile? Iswishi ye-PoE iyiswishi esebenza nge-PoE engaxhunywa kuswishi evamile.

I-1.Izishintshi ze-Sturdiness Industrial zenzelwe futhi zenziwa kusetshenziswa izingxenye zebanga lezimboni. Lezi zingxenye zikhethwa ngokukhethekile ukuze zimelane nezindawo ezinokhahlo futhi zinikeze ukusebenza okuphakeme ngisho nangaphansi kwezimo ezinzima. Ukusetshenziswa kwemboni...

Ubuchwepheshe bamandla phezu kwe-Ethernet (POE) buye bashintsha indlela esinika amandla ngayo amadivayisi ethu, sinikeza ukunethezeka, ukusebenza kahle nokonga izindleko. Ngokuhlanganisa amandla nokudluliswa kwedatha kukhebula ye-Ethernet, i-POE iqeda isidingo sentambo yamandla ehlukile, okwenza...

Sethula ubuchwepheshe benethiwekhi bakamuva, i-JHA Web Smart Series compact Ethernet switch. Lawa mashishi okonga isikhala futhi angabizi kakhulu aklanyelwe ukuhlangabezana nezidingo ezikhulayo ze-Industrial Ethernet. Ukushintsha okuhlanganisiwe kwe-JHA Web Smart Series ...

I-Shenzhen JHA Technology Co., Ltd. (JHA) yasungulwa ngo-2007 futhi ikomkhulu layo lise-Shenzhen, eChina. Ingumkhiqizi ohamba phambili wezokuxhumana nge-fiber optical kanye nemikhiqizo yokudlulisela evikelekile. I-JHA igxile kwi-fiber optic yezimboni nezentengiso...

Kulesi sihloko, sizoxoxa ngezisekelo zokushintshwa kwenethiwekhi futhi sihlole amagama abalulekile afana ne-Bandwidth, Mpps, Full Duplex, Management, Spanning Tree, kanye ne-Latency. Kungakhathaliseki ukuthi ungumuntu oqalayo wezokuxhumana noma othile ofuna ukwandisa ulwazi lwakho, lesi sihloko ...

Ezweni lanamuhla elisheshayo, ubuchwepheshe buthuthuka ngesivinini esisheshayo. Njengoba isidingo sabantu sokuxhumeka kwenethiwekhi okusebenzayo nokulula sikhula, okokusebenza okufana nokushintsha kwe-POE sekubalulekile. Ngakho-ke kuyini ngempela ukushintshwa kwe-POE nokuthi yiziphi izinzuzo ...

I-SMART NATION EXPO 2023 ibibanjelwe kahle e-Kompleks MITEC. Lo mbukiso ubandakanya amandla ahlakaniphile, imvelo, ubuchwepheshe bolwazi, ukwakhiwa, ukunakekelwa kwezempilo, amanethiwekhi e-5G, amakhadi ahlakaniphile neminye imikhakha. Lo mbukiso uphinde waba nezinkundla eziningi, izingqungquthela,...
