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

(3）rbeka inani eliphakeme labasingathi abaxhumeke nembobo, isixhumi esibonakalayo se-Ethernet esibopha kaningi , ukwandisa umkhawulokudonsa kanye nokungafuneki kwesistimu

(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

Umhlahlandlela Womkhiqizo Ohlobene:

Kungakhathaliseki ukuthi umthengi omusha noma ikhasimende elidala, Sikholelwa ekukhulumeni okude kakhulu nasebudlelwaneni obuthembekile be-2019 Good Quality Managed Network Switch - 24+4 Management Gigabit Switch JHA-S2404MG-28BC - JHA , Umkhiqizo uzohlinzeka emhlabeni wonke, ezifana njengoba: Rwanda, Czech republic, Tunisia, Inkampani yethu ihlanganisa indawo 20, 000 square metres. Sinezisebenzi ezingaphezu kuka-200, ithimba lezobuchwepheshe elichwepheshile, isipiliyoni seminyaka engu-15, umsebenzi omuhle kakhulu, izinga elizinzile nelithembekile, intengo yokuncintisana namandla okukhiqiza anele, yile ndlela esenza ngayo amakhasimende ethu aqine. Uma unombuzo, sicela ungangabazi ukusithinta.
