Antaira Technologiesi LMX-2004G-SFP on 20-portiline tööstuslik Gigabiti hallatav Ethernet-kommutaator, mis sisaldab 16*10/100/1000Tx Ethernet-porti ja 4*100/1000 SFP-pesa. LMX-2004G-SFP on täielikult hallatav kerge 3. kihi Ethernet-kommutaator, mis on eelnevalt varustatud kasutajasõbraliku veebihalduskonsooli disainiga. See toetab ringvõrgu redundantsfunktsiooni, kasutades turu avatud standardit ITU-T G.8032 ERPS (Ethernet Ring Protection Switch), mille võrgu taastumisaeg on <50 ms. Täiustatud võrgu filtreerimis- ja turvafunktsioonid, nagu IGMP, VLAN, QoS, SNMP, portide lukustamine, RMON, Modbus TCP ja 802.1X/HTTPS/SSH/SSL, suurendavad determinismi ja parandavad võrgu haldamist kaugjuhtimissüsteemide või juhtimisvõrkude puhul.
LMX-2004G-SFP on IP30-klassi ja DIN-riba paigaldatav. Samuti on standardne temperatuurivahemik (STD: -10°C kuni 70°C). See pakub ka kõrget EFT- ja ESD-kaitset tööstuslike võrgurakenduste jaoks, näiteks elektri- ja kommunaalteenuste, vee- ja reovee-, nafta-, gaasi- ja kaevandamisvõrkude, tehaste automatiseerimise, transpordi turvaseire, intelligentsete transpordisüsteemide ja mis tahes muu välitingimustes või rasketes tingimustes kasutatava keskkonna jaoks.
Toetab 16*10/100/1000Tx RJ45 porti.
Toetab 4*100/1000 SFP-pesa
