Antaira Technologies has unveiled two advanced managed gigabit switch models specifically designed for low-voltage industrial networking applications. The LMP-2804G-4XS-24-T and LMP-2812G-4X8S-24-T models are equipped to operate with input voltages ranging from 12 to 55VDC through dual power inputs. Featuring an integrated DC-to-DC power boost function that converts 12VDC – 36VDC inputs to 48-55VDC, these switches enable IEEE PoE standard compliance and the delivery of 30 watts per port.The LMP-2804G-4XS-24-T boasts 24 Gigabit Ethernet 802.3at PoE ports along with four 1G/2.5G/10G SFP+ fiber optic slots. Power output varies depending on the input voltage: 150W at 12VDC, 300W at 24VDC, and 720W at 48-55VDC. On the other hand, the LMP-2812G-4X8S-24-T comes with 16 Gigabit Ethernet 802.3at PoE ports, four 10G SFP+ fiber slots, and eight 1G SFP fiber slots, delivering power outputs of 150W at 12VDC, 300W at 24VDC, and 480W at 48-55VDC.
Both models are equipped with iPoE Budget Control technology for dynamic power management based on input voltage levels. The system effectively limits PoE output to 90W at 12VDC input, which increases to 240W at 48VDC input. In cases where power demand exceeds the available budget, the system automatically prioritizes lower-numbered ports while deactivating higher-numbered ports to maintain system stability.
These switches are designed to operate efficiently in temperatures ranging from -40°F to 167°F, featuring a fanless design housed in an 8-inch depth structure. Key network management features include multi-user accounts, IGMP snooping, GVRP, VLAN segmentation, QoS traffic prioritization, and SNMP. Additionally, security protocols such as Static link aggregation, Link Aggregation Control Protocol, ARP inspection, RADIUS, TACACS+, SSH, and IP Source Guard are included.
The IP30-rated metal enclosure provides EFT/ESD protection and vibration resistance. Both models are currently pending certification for Class I, Division 2 hazardous locations and compliance with the IEC 61850-3 protocol for substation installations. For network redundancy, G.8032 ERPS protocols are utilized for ring architectures.
