Ukulethwa okusheshayo 1000base Lx Sfp 1310nm 10km - 24+4 Management Gigabit Switch JHA-S2404MG-28BC - JHA Imininingwane:
24+4 Ukuphatha Gigabit Shintsha I-JHA-S2404MG-28BC
♦PumkhiqizoTHEukubuka konke
I-24+4 Management Gigabit Switch iyiswishi evamile engavimbeli. Ihlinzeka ngamachweba angu-24*10/100/1000Base-T, amachweba we-SFP angu-4*1000M; Umthamo wokushintsha we-56Gbps, ukusebenza kokudlulisa okungu-41.644Mpps, amandla okuxhumana aguquguqukayo aqinisekisa ukuzinza kwenethiwekhi kanye nebhalansi yesixhumanisi somthwalo. okunikeza umkhawulokudonsa owanele wokuhlanganisa idatha kanye nokushintshisana kwedatha.Futhi ukuze baphendule ngokuguquguqukayo ezidingweni zenethiwekhi, abasebenzisi bangakhetha izimbobo ze-Gigabit ezifanele ngokwezidingo zabo; Ifanele amabhizinisi amancane naphakathi nendawo, inethiwekhi yekhampasi, amakhefi e-inthanethi kanye nokusetshenziswa kwe-MAN.
♦ UmkhiqizoKeyFizidlakudla
1 . Ukusebenza okuphezulu

(4)pI-ACL enamandla, isekela ukuhlunga kwedatha ye-L2-L4
(5)inqubomgomoUhlu lokulawula kanye nokulawulwa kokugeleza
3 . Ukulungisa Kalula
(1)sekela ukucushwa kwembobo eguquguqukayo
(2)ekwazi ukuphathwa ngeIwebhu, SNMP,njll
(3)sthuthukisa iphrothokholi ye-XModem, sebenzisa i-TFTP/ZMODEM ukuze uthuthukise isofthiwe futhi uthuthukise i-BootRom
4 . Ukugeleza Okunamandla Nokuphathwa Kokusakaza
(1) thola futhi ulawule ngokuzenzakalelayo isiphepho sokusakaza, sekela ukutholwa kwamaphakethe e-IGMP, unciphise ngempumelelo ukugcwala kwamaphakethe okusakaza.
(2)ssekela imodi egcwele ye-duplex kanye nokulawula ukugeleza kwemodi ephindwe kabili
(3)sisixhumanisi esibonakalayo se-Ethernet esithatha u-1M njengobude besinyathelo sokukhawulela izinga
