Antaira LMP-1204G-SFP-T 12-Port Gigabit Managed Industrial Ethernet Switch with 8x PoE+, 4x SFP and -40 to 75 °C

Outdoor cabinets on ITS, oil and gas and utility networks are rarely heated, so the switch inside has to start and run through hard frost and summer sun while it powers devices and holds the ring together. The LMP-1204G-SFP-T is the extended temperature model in the Antaira LMP-1204G-SFP series, a 12-port Layer 2 managed industrial PoE+ switch rated -40 °C to 75 °C.

It carries eight 10/100/1000 RJ45 ports with IEEE 802.3at/af PoE+ at up to 30 W per port and four 100/1000 dual-rate SFP slots for single-mode or multi-mode fiber, with reach set by the module fitted. Store-and-forward switching runs on a 24 Gbps fabric with an 8K MAC table and 9.6K jumbo frames. ITU-T G.8032 ERPS brings a broken ring back in under 50 ms, and STP, RSTP, MSTP, LACP, 802.1Q VLANs, QoS, IGMP and Modbus TCP cover the rest of the Layer 2 toolset.

Redundant 48 to 55 V DC inputs land on a removable 6-contact terminal block, protected against overload current and reverse polarity. The PoE ping alarm restarts a port whose device has stopped responding, which can save a site visit to a remote camera, and a relay output and e-mail alerts flag faults. 802.1X, SNMPv3, HTTPS and SSH secure management from the web console, Telnet or CLI.

The LMP-1204G-SFP-T sits in an IP30 metal case for DIN-rail or optional wall mounting. Antaira lists FCC, CE, UL 61010-1, UL Class 1 Division 2, NEMA TS2 and ATEX Zone 2 approvals and backs it with its 5-year warranty. The LMP-1204G-SFP is the standard temperature model for heated cabinets, and the LMP-1204G-SFP-bt-T adds 90 W 802.3bt ports at the same rating. We supply and specify the switch, and pre-configure IP addressing, VLANs and ring settings where you ask.
