Unikezelo oluKhawulezayo 120W Ubonelelo lwaNgaphakathi lwaMandla IEEE802.3af/at 4 Port Ethernet switch POE

Inkcazo:

I-HDV-4GE POE + 2GE UP-ND ngumgangatho oqhelekileyo we-PoE onikwe amandla we-Ethernet switch eyenzelwe kwaye iphuhliswe ngezixhobo zonxibelelwano ze-HDV.Yamkela isitshiphu sokutshintsha se-Ethernet esinesantya esiphezulu samva nje kunye noyilo lwebhanwidth ekumgangatho ophezulu.Inamandla okusebenza kwedatha kwaye iphucula ukusebenza kakuhle kokuhanjiswa kwedatha.Ixhasa i-4 * 10/100/1000Mbps Ethernet RJ45 izibuko kunye nomsebenzi we-PoE kunye ne-2 * 10/100/1000Mbps i-Ethernet uplink RJ45 izibuko, izibuko ngalinye lixhasa umsebenzi we-auto rollover (Auto MDI / I-MDIX) .Phakathi kwabo, i-4 izibuko ezinomsebenzi we-PoE, zonke zixhasa i-IEEE 802.3af / kunikezelo lwamandla oluqhelekileyo lwe-PoE, olunokusetyenziswa njengesixhobo sombane we-Ethernet.Amandla ombane aphezulu kwi-port enye yi-30W kwaye amandla aphezulu omatshini wonke yi-120W.Iyakwazi ukubona ngokuzenzekelayo kwaye ichonge i-IEEE 802.3af / kwi-standard Powered equipment.Inikwe amandla yintambo yothungelwano, ixhasa i-250 yeemitha zokuhanjiswa komgama omde kwaye ixhasa unikezelo lwamandla oluphambili.

Iimbonakalo:
• Ukusebenza kweZibuko
Ukubonelela nge-4 * 10/100/1000Mpbs RJ45 i-adaptive high-speed forwarding data port;
Ukubonelela nge-2 * 10 / 100/1000Mpbs RJ45 uplink port;
Ichweba ngalinye lixhasa i-MDI / MDIX i-rollover ngokuzenzekelayo kunye ne-auto-negotiation, kwaye ixhasa i-IEEE 802.3x yokulawula ukuhamba kwe-duplex epheleleyo kunye ne-Backpressure half-duplex flow flow;
• Ukusebenza kwamandla e-PoE
I-4 * 10 / 100/1000Mpbs i-RJ45 port isekela ukunikezelwa kwamandla e-PoE +, ukuhlangabezana neemfuno zokunikezelwa kwamandla e-PoE ekujongeni ukhuseleko, inkqubo ye-teleconference, i-wireless coverage kunye nezinye iimeko;
Ukuthobela i-IEEE 802.3af / kumgangatho wonikezelo lwamandla we-PoE, amandla aphezulu emveliso ye-PoE yomatshini wonke yi-120W, kwaye ubuninzi be-PoE yokuphuma kwamandla kwi-port enye yi-30W;
Ukuchonga ngokuzenzekelayo izixhobo ze-PoE zobonelelo lwamandla ngaphandle kokonakalisa izixhobo ezingezizo ezo-PoE;
Izibuko le-PoE lixhasa indlela ephambili.Xa amandla aseleyo angonelanga, aqinisekisa unikezelo lwamandla kwizibuko eliphambili kuqala ukuphepha ukulayisha ngaphezulu isixhobo;
• Izixhobo ezizinzileyo nezithembekileyo
Ukusetyenziswa kwamandla aphantsi kunye noyilo oluzolileyo lomninimzi luqinisekisa ukusebenza okuzinzile kwemveliso;
Yamkela unikezelo lwamandla oluphuhliswayo kunye noyilo olungafunekiyo kakhulu ukubonelela ngemveliso yamandla exesha elide ezinzileyo yePoE;
Isixhobo sihlangabezana nemigangatho ye-CCC yesizwe, ihlangabezana ngokupheleleyo neemfuno zokhuseleko, kwaye ikhuselekile kwaye inokwethenjelwa ukuyisebenzisa;
• Ukusebenza okulula kunye nokuqina okunamandla
Kulula kwaye kulula ukuyisebenzisa, akukho lungelelwaniso, iplagi kunye nokudlala, ukuhambelana okuqinileyo;
Ukuhanjiswa kwesantya esiphezulu, idatha ngaphandle kokulahleka kwepakethi, ukwandiswa okuguquguqukayo, ukwenzela ukuba inethiwekhi ingathinteli ngokucwangcisa imigca yamandla, ukugcina iindleko zomsebenzisi;
Dibana nemo yenethiwekhi efuna unikezelo lwamandla oluxinana kakhulu lwePoE;
Ilungele imali, ii-arhente zikarhulumente, iihotele, iindawo zokuthenga, iikhampasi, izibhedlele kunye namashishini amancinci naphakathi ukwenza amanethiwekhi angabizi kakhulu;
