Iminyaka Eyisi-8 Yokuthekelisa 8 I-Poe Switch - 8 10/100/1000TX + 2 1000FX | I-Fiber Ethernet Switch JHA-G28LN (Inethiwekhi Yokukhala Ngaphandle Kokusetha) – JHA
Iminyaka Eyisi-8 Yokuthekelisa 8 I-Poe Switch - 8 10/100/1000TX + 2 1000FX | I-Fiber Ethernet Switch JHA-G28LN (Inethiwekhi Yokukhala Ngaphandle Kokusetha) - Imininingwane ye-JHA:
Isingeniso
Uchungechunge lwe-JHA-G28LN olugcwele amaswishi e-fiber ye-gigabit ring network ahlinzeka ngokulawuleka kangcono, isekela i-QoS, okuhlanganisa i-VLAN, i-mirroring, i-port isolation, ukwesekwa okunwetshwa kwesihlahla i-STP (802.1D) ne-RSTP (802.1w) kanye nomklamo owodwa wenethiwekhi ye-fiber ring ilungele- ukusetshenziswa kwesayithi. Idizayini yomkhiqizo ivumelana nezinga le-Ethernet, yengeza ukuvikela kombani nezinyathelo zokuvikela eziqinile, futhi inebanga elibanzi lokushisa lokusebenza ukusuka -20°C kuya ku-70°C, nokusebenza okuzinzile nokuthembekile.
Idivayisi ingasetshenziswa kabanzi emikhakheni ehlukahlukene yokudlulisa idatha ye-broadband njengezakhiwo ezihlakaniphile, amadolobha ahlakaniphile, imiphakathi ehlakaniphile, ezokuthutha ezihlakaniphile, ezokuxhumana, ezokuphepha, izibambiso zezimali, amasiko, ezokuthutha, ugesi, ukongiwa kwamanzi nezinkundla zikawoyela.
Izici

* Sekela 9600bytes jumbo uhlaka;
* Uchungechunge lwebanga lokudlulisela luqediwe, olungakwazi ukubona ukudluliswa kokufika ku-120KM;
* Asikho isidingo sokusetha inethiwekhi yendandatho, ingalungisa ngokushesha imisebenzi yenethiwekhi;
* Ukusekela ukusakaza umsebenzi wokucindezela isiphepho;
* Ukusekela i-IEEE802.3/802.3u/802.3x IEEE802.3D/IEEE802.3W;
* Sekela i-ultra-low latency kanye nobuchwepheshe bokulondolozwa kwesikhashana okunwebekayo: sebenzisa imodi "yesitolo naphambili", xhuma ngaphandle komthungo amadivaysi ejubane elihlukile, futhi imodi yokusebenza iguquguquke;
* Sekela ikheli le-MAC le-16K;
