Antaira LMP-1600G-T 16-Port Gigabit Managed Industrial Switch with 16x PoE+ (240W) and -40 to 75 °C

Unheated outdoor cabinets on ITS, utility and surveillance networks can hold a dozen or more cameras and sensors, all of them needing power and a managed link through frost and summer heat. The LMP-1600G-T is the extended temperature model in the Antaira LMP-1600G series, a 16-port Light Layer 3 managed industrial PoE+ switch rated -40 °C to 75 °C.

All 16 ports are 10/100/1000 RJ45 with IEEE 802.3at/af PoE+ at up to 30 W per port, drawing on a 240 W total budget, so a fully loaded switch averages 15 W per port. Store-and-forward switching runs on a 32 Gbps fabric with an 8K MAC table and 9.6K jumbo frames. The Light Layer 3 firmware adds static routes and DHCP Option 82 to 802.1Q VLANs, QoS, IGMP v1/v2/v3 snooping, LACP and Modbus TCP, and ITU-T G.8032 ERPS restores the ring in under 50 ms, with STP, RSTP and MSTP as alternatives.

Power comes in on redundant 48 to 55 V DC inputs through removable terminal blocks, with overload current and reverse polarity protection. The switch draws 13.8 W itself, and a 24 V DC, 1 A relay contact and system warnings report power loss or port faults. Security covers 802.1X, SNMPv3, HTTPS, SSH and port lock, and an RS232 console and USB configuration backup simplify replacing a unit in the field.

The LMP-1600G-T runs fanless in an IP30 metal case for DIN-rail or wall mounting. Antaira lists FCC, CE, UL 61010-1 and NEMA TS2 approvals, IEC 61850-3 Edition 2.0 for substation use and its 5-year warranty. The LMP-1600G is the standard temperature model, and the LNP-1600G-T is the unmanaged alternative at this rating where VLANs and ring control are not needed. We supply and specify the switch, and pre-configure IP addressing, VLANs and ring settings where you ask.
