Kwixesha lanamhlanje ledijithali, iiswitshi ze-Ethernet zidlala indima ebalulekileyo ekusekeni nasekugcineni unxibelelwano olungenamthungo lwenethiwekhi. Ukuqonda iimpawu zabo kunye neenzuzo kubalulekile, ngakumbi kubantu abafuna ukwandisa ukusebenza kwenethiwekhi. Eli nqaku lijolise ekunikezeni isikhokelo esibanzi kwiiswitshi ze-Ethernet kunye nendlela abanokuphucula ngayo ukuthembeka kwenethiwekhi. Ukutshintsha kwe-Ethernet sisixhobo esidibanisa izixhobo ezininzi, ezinjengeekhompyuter, iiseva, kunye nabashicileli, kwinethiwekhi yendawo yendawo (LAN) okanye inethiwekhi yendawo ebanzi (WAN). Isebenza njenge hub ephakathi eyenza unxibelelwano phakathi kwezi zixhobo ngokuthumela iipakethi zedatha kwindawo efanelekileyo.

Utshintsho lwe-PoE lusebenza njengokutshintsha, kwaye ngokuqinisekileyo lunokusetyenziswa njengokutshintsha okuqhelekileyo. Nangona kunjalo, xa isetyenziswe njengenguqu jikelele, ixabiso lokutshintsha kwe-PoE alinyuswanga, kwaye imisebenzi enamandla yokutshintsha kwe-PoE iyachithwa. Ngoko ke, kukho iimeko apho kungekho mfuneko yokubonelela amandla e-DC kwisixhobo esiqhagamshelwe kwaye kufuneka kuphela ukuhambisa idatha. , Kucetyiswa ukuba ukhethe ukutshintshela rhoqo, kwaye ukuba awufuni kuphela ukuhanjiswa kwedatha kodwa kunye nokunikezelwa kwamandla, kungcono ukhethe i-PoE switch. Ukuba ufuna ukuguqula iswitshi eqhelekileyo kwiswitshi ye-PoE, ukuba udibanisa ngokuthe ngqo iswitshi eqhelekileyo kwisitshixo se-PoE, unikezelo lwamandla kunye nokuhanjiswa kwedatha akunakufezekiswa ngokupheleleyo ngexesha elinye.

Ukutshintsha kwe-PoE luhlobo olutsha lokutshintsha kwemisebenzi emininzi. Ngenxa yokusetyenziswa ngokubanzi kokutshintsha kwePoE, abantu banokuqonda okuthile kokutshintsha kwePoE. Nangona kunjalo, abantu abaninzi bacinga ukuba iiswitshi ze-PoE zinokuvelisa amandla ngokwazo, okungeyonyani. Umbane we-PoE switch udla ngokubhekisa kwiswitshi ye-PoE enika amandla kwezinye izixhobo ngentambo yenethiwekhi ngaphandle kokuphulukana namandla okuhambisa idatha. Ke ngaba ukutshintshela kwePoE kunokusetyenziswa njengokutshintsha okuqhelekileyo? Ukutshintsha kwe-PoE kukutshintsha kunye nokusebenza kwe-PoE enokuthi idibaniswe nokutshintsha okuqhelekileyo.

Amandla phezu kwe-Ethernet (POE) iteknoloji iye yaguqula indlela esisebenzisa ngayo izixhobo zethu, ukubonelela ngokulula, ukusebenza kakuhle kunye nokonga iindleko. Ngokudibanisa amandla kunye nokuhanjiswa kwedatha kwikhebula le-Ethernet, i-POE iphelisa imfuno yentambo yamandla eyahlukileyo, ukwenza ...

Ukwazisa itekhnoloji yenethiwekhi yamva nje yokusika, iJHA Web Smart Series compact Ethernet switches. Ezi zitshintshi zokulondoloza indawo kunye neendleko ezisebenzayo zenzelwe ukuhlangabezana neemfuno ezikhulayo ze-Industrial Ethernet. I-JHA Web Smart Series itshintshela icompact ...

Kule nqaku, siza kuxubusha iziseko zokutshintsha kwenethiwekhi kwaye sihlolisise amagama abalulekileyo afana ne-Bandwidth, Mpps, Full Duplex, Management, Spanning Tree, kunye neLatency. Nokuba ungumqali wenethiwekhi okanye umntu ojonge ukwandisa ulwazi lwakho, eli nqaku ...

Kwihlabathi lanamhlanje elikhawulezayo, iteknoloji ikhula ngokukhawuleza. Njengoko imfuno yabantu yonxibelelwano olusebenzayo nolulungeleyo lwenethiwekhi iqhubeka ikhula, izixhobo ezinje ngokutshintsha kwe-POE ziye zayimfuneko. Ke yintoni kanye kanye i-POE yokutshintsha kwaye zeziphi iingenelo ...

1. I-PoE engekho mgangathweni kunye ne-PoE esemgangathweni Kumgangatho we-PoE ohambelana nemigangatho ye-IEEE 802.3af/at/bt kwaye ineprothokholi yokuxhawula izandla. I-PoE engekho mgangathweni ayinayo iprotocol yokuxhawula izandla, kwaye ibonelela nge-12V, 24V okanye i-48V DC esisigxina yombane. Umgangatho wePoE po...
