Amandla phezu kwe-Ethernet (i-PoE) iteknoloji yokubonelela ngombane esekelwe kwinethiwekhi yendawo yendawo (LAN), enokudlulisa amandla kunye nedatha kwisixhobo ngentambo yenethiwekhi kwi-Ethernet. Ukusetyenziswa kobu buchwepheshe kunokunciphisa kakhulu iindleko zokusebenza kunye nokugcina ixesha lokusebenza. Okwangoku, kukho utshintsho oluhlukeneyo olusekelwe kwi-teknoloji ye-PoE kwimarike, ngokukodwa i-PoE switch, i-PoE + switch, kunye ne-PoE ++.Nceda ulandeleI-JHA TECHukuqonda umahluko phakathi kwezi switshi.

Yintoni i-PoE? Yintoni utshintsho lwePoE?

I-PoE (ekwabizwa ngokuba yi-IEEE 802.3af standard) ngumgangatho omtsha osekelwe kwi-Power over Ethernet system epapashwe liqela elisebenzayo le-IEEE 802.3 ngo-2003. Umgangatho uchaza ukuba isixhobo sokufumana amandla (PD), njengefowuni yeVoIP. , kufuneka kusetyenziswe izibini ezimbini ezijijekileyo zentambo yothungelwano efanayo ukuba inikwe amandla ngexesha lenkqubo yokufumana amandla, kunye nokusetyenziswa kwamandla ePoE kunokufikelela ukuya kuthi ga. 12.95W.

Ukutshintsha kwe-PoE, okukwabizwa ngokuba yi-PoE yokutshintshela umbane, sisicelo esisekwe kubuchwephesha be-PoE. Kukutshintsha okunokubonelela ngombane kunye nokuhanjiswa kwedatha kwi-terminal yokufumana ngexesha elifanayo ngekhebula lomnatha, kwaye lilungu lesixhobo se-terminal terminal (PSE). Ngokuqhelekileyo, utshintsho lwe-PoE oluhambelana nomgangatho we-802.3af lunokuxhasa unikezelo lwamandla oluphezulu lwe-15.4W kwizibuko ngalinye, kwaye umbane wombane wombane yi-44V-57V. I-voltage yegalelo yesixhobo se-PoE esiqhagamshelwe kulo tshintsho lwe-PoE yi-37V-57V.

Yintoni i-PoE+? Yintoni iswitshi ye-PoE+?

I-PoE + (ekwabizwa ngokuba ngumgangatho we-IEEE 802.3af), njengophuculo kwi-teknoloji ye-PoE, ngumgangatho wezobuchwepheshe we-PoE okhutshwe ngo-2009. Ngokusetyenziswa ngokubanzi kweteknoloji ye-PoE, ezinye izixhobo zokufumana amandla njenge-wireless APs zifuna amandla amaninzi. ngaphezu kwe-12.95W. Ukuze kulungiswe le ngxaki, iqela elisebenzayo le-IEEE 802.3 likhuphe iteknoloji ye-PoE + eyenzelwe ukunika amandla aphezulu kwizixhobo.

Ukutshintsha kwePoE + kuyafana nokutshintsha kwePoE esikukhankanyileyo ngasentla, kwaye ikwabonelela ngamandla kwisixhobo sokuphela kwePoE ngentambo yenethiwekhi. Umahluko kukuba amandla ombane aphezulu kwi-port nganye ye-PoE + switch yi-30W, kunye nombane wombane we-50V-57V. Amandla ombane aphezulu afunyenwe kwisixhobo sokufumana amandla anganyuswa abe yi-25.5W, kwaye i-voltage inokunyuswa ukuya kwi-42.5V-57V.

Yintoni i-PoE++? Yintoni utshintsho lwe-PoE++?

Ngophuhliso oluqhubekayo lwemarike yesicelo se-PoE, umgangatho we-IEEE 802.3 wongeze umgangatho we-IEEE 802.3bt. Ngeli xesha, iteknoloji ye-PoE ++ iye yavela. Ngaphantsi komgangatho we-IEEE 802.3bt, iteknoloji ye-PoE ++ ineentlobo ezimbini zesebe. Enye iteknoloji ye-PoE ++ ebizwa ngokuba yi-Type3 inokunikwa amandla ngamabini amabini okanye amane ajikiweyo kwintambo yenethiwekhi efanayo, kwaye inokubonelela nge-51W yamandla okufakelwa kwisixhobo sokufumana amandla.Enye iteknoloji ye-Type4PoE ++, efuna ukunika amandla kwi-PoE. isixhobo se-terminal ngokusebenzisa zonke izibini zentambo yenethiwekhi, kwaye amandla okufaka anokufikelela kwi-71W. Ukongezelela, kukho iteknoloji ye-PoE esekelwe kumgangatho we-IEEE 802.3bt obizwa ngokuba yi-UPOE (amandla e-universal phezu kwe-Ethernet). Le teknoloji isemthethweni kwiCisco, kwaye imodi yokusebenza ifana neteknoloji ye-Type3PoE (i-PoE ++), kwaye amandla okufakwayo anokunikezelwa kwisixhobo sokugqibela sokufumana i-51W. Ke ngoko, abanye abantu kwishishini baya kujonga i-UPOE njengePoE ++.

Njengokuphuculwa kokutshintsha kwe-PoE kunye nokutshintsha kwe-PoE +, ukutshintshwa kwe-PoE ++ kunokubonelela ukuya kwi-60W yonikezelo lwamandla kwi-port ye-Type3PoE ++ yokutshintsha, kunye ne-100W ye-Type4. Jonga kwitheyibhile engezantsi ukujonga iiparamitha ezithile zokutshintsha kwePoE ++ kunye nezinye iindidi ezimbini zokutshintsha.
