Antaira LMX-0804G-SFP-T 8-Port Gigabit Managed Industrial Ethernet Switch with 4x SFP and -40 to 75 °C

Fiber aggregation points out on a site, in roadside cabinets, outstations or utility kiosks, are rarely heated and can see a wide temperature swing. The LMX-0804G-SFP-T is the extended temperature build in the Antaira LMX-0804G-SFP series: an eight-port managed gigabit switch with four SFP slots, rated -40 °C to 75 °C.

It has four 10/100/1000Base-TX RJ45 ports with auto MDI and four 100/1000 dual-rate SFP slots that take single-mode or multi-mode modules, so wavelength and reach follow the transceiver chosen. Switching is store-and-forward on a 16 Gbps fabric with an 8K MAC table and 9.6 KB jumbo frames. This is a Layer 2 managed switch: IEEE 802.1Q VLANs, QoS with CoS/ToS, IGMP v1/v2 snooping for up to 256 groups, LACP, LLDP, RMON, port mirroring, IPv4/IPv6, DHCP Option 66/67/82, Modbus TCP and 802.1X with HTTPS and SSH/SSL. Ring redundancy uses ITU-T G.8032 ERPS with recovery in under 50 ms, alongside STP, RSTP and MSTP.

Power arrives on 12 to 48 V DC redundant inputs on a removable 6-contact terminal block, and the switch draws up to 15 W. Overload current protection is built in, and with reverse polarity protection the switch will not power on if the supply is reversed. Exceptions can trigger an e-mail or the relay output, and Antaira gives the switch high EFT and ESD protection. Set-up runs through the web console, Telnet or CLI, with an RS232 console port on RJ45 and USB 2.0 configuration backup.

The LMX-0804G-SFP-T sits in an IP30 metal case for DIN rail mounting, with wall mounting as an option. It is UL 61010-1 certified, carries FCC and CE marks, is RoHS compliant and comes with Antaira’s 5-year warranty. The LMX-0804G-SFP is the same switch rated -10 °C to 70 °C, and the LMX-1002G-SFP-T offers eight copper ports and two SFP slots at the same rating. We supply and specify the LMX-0804G-SFP range, with IP addressing, VLANs and ring settings pre-configured before it ships if you would like.
