48+4 10G Ukuphathwa Kwe-Fiber Ethernet Shintsha

I-JHA-SW4804MG-52VS

Pumkhiqizo ukubuka konke

I-JHA-SW4804MG-52VS iwuchungechunge olujwayelekile lwe-BCM chip switch.

Idizayini ye-modular inikeza izimbobo eziguquguqukayo ezingu-48 10/100/1000 kanye nezimbobo ezi-4 ezihlanganisiwe ze-terabyte, ehlinzeka ngomkhawulokudonsa owanele wokushintshaniswa kwedatha phakathi kokuhlanganisa kanye nomnyombo.

Nikeza umthamo wokushintshanisa umthamo ophezulu, inqubomgomo yokulawula ukuphepha ephelele kanye nenqubomgomo yokuvikela ye-CPU ukuze kuthuthukiswe ukubekezelelana kwamaphutha, nokuqinisekisa ukusebenza okuzinzile kwenethiwekhi kanye nebhalansi yomthwalo wesixhumanisi.

Ngaleso sikhathi, isekela ukuvimbela ukuhlasela kwe-DoS okuzenzakalelayo kanye ne-SNMP, IEEE 802.1, isihlahla esinwebekayo, umthetho olandelwayo wesihlahla onqamula ngokushesha, ukuhlanganisa izixhumanisi neminye imisebenzi.

Pumkhiqizo izici
