Abathengisi Abahle Bezitolo Ezinhle 24 I-Port Fiber Switch - 48+4 10G Management Fiber Ethernet Switch JHA-SW4804MG-52VS – JHA Imininingwane:
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

Ø isekela i-SFP +, kanye nokuhambisana emuva kwe-XFP, njll
9.Ithrafikhi eqinile nokuphathwa kokusakaza
Ukutholwa okuzenzakalelayo nokucindezelwa kwesiphepho esisakazwayo, sekela ukutholwa komlayezo we-IGMP, kukhawulele ngempumelelo ukugcwala komlayezo wokusakaza
I-Ø isekela imodi ye-duplex egcwele kanye nemodi ye-duplex enguhhafu yokulawula ukugeleza
Ø isekela isixhumi esibonakalayo se-Ethernet nge-1 m njengezinga lokulinganisa ubude besinyathelo

♦ Ukuthuthwa nokugcinwa komkhiqizo
♦ Ukuthutha: ukupakishwa kwalo mkhiqizo kulungele ukuthuthwa kwezimoto, imikhumbi, izindiza nezitimela. Ngesikhathi sokuthutha, kufanele ivikelwe elangeni, ukucwiliswa kwamanzi kanye nokulayisha okuphucuzekile nokuthulula.
♦ Isitoreji: umkhiqizo kufanele ubekwe ebhokisini lokupakisha uma ungasetshenziswa. Izinga lokushisa kanye nomswakama wendawo yokugcina impahla kufanele kuhlangabezane nezidingo zomkhiqizo. Akufanele kube khona izinto ezonakalisayo endaweni yokugcina izinto futhi kungabikho ukudlidliza komshini okuqinile, umthelela kanye nesenzo sensimu kazibuthe.
Izithombe zemininingwane yomkhiqizo:
Umhlahlandlela Womkhiqizo Ohlobene:
Sisebenzisa ingqikithi yenqubo yokuphatha ikhwalithi enhle yesayensi, ikhwalithi ephezulu nokholo oluhle kakhulu, sithola igama elihle futhi sathatha le nkambu yabaThengisi Abahle I-Good Wholesale Vendors 24 Port Fiber Switch - 48+4 10G Management Fiber Ethernet Switch JHA-SW4804MG-52VS – JHA , The umkhiqizo uzohlinzekwa kuwo wonke umhlaba, njengalokhu: i-Sri Lanka, i-Niger, i-Uruguay, Kuze kube manje, uhlu lokuthengiswayo lubuyekezwa njalo futhi luhehe amakhasimende avela emhlabeni wonke. Imininingwane enemininingwane ingatholakala ekhasini lethu lewebhu futhi uzonikezwa isevisi yomeluleki yekhwalithi enhle yithimba lethu langemva kokuthengisa. Bazokuvumela ukuthi uthole ukuvuma okuphelele mayelana nezinto zethu futhi wenze izingxoxo ezigculisayo. Amabhizinisi amancane hlola efektri yethu e-Uganda angamukeleka nganoma yisiphi isikhathi. Ngiyethemba ukuthola imibuzo yakho ukuze uthole ukubambisana okujabulisayo.
Ngu-Joa wase-Iceland - 2018.06.09 12:42 Sihlale sikholelwa ukuthi imininingwane inquma ikhwalithi yomkhiqizo wenkampani, kulokhu, inkampani ivumelana nezimfuneko zethu futhi izimpahla ziyahlangabezana nesikulindele.
