Antaira LMP-2004G-SFP 20-Port Managed Gigabit Ethernet Switch, 16 PoE+ Ports and 4 SFP slots

Engineers and IT professionals count on Antaira Technologies to deliver performance and reliability. The LMP-2004G-SFP is no exception. It’s an industrial Ethernet switch featuring network management, 16 Gigabit Power over Ethernet (PoE) ports, quad fiber-optic SFP slots, and industrial-certified ruggedness. It simultaneously powers multiple PoE devices and handles heavy data loads without buckling. It’s ideal for aggregating security camera streams onto the fiber lines then transmitting the feeds over long distances.

Networks must be easily configurable for expansion but safe from intrusion. That’s why the LMP-2004G-SFP embeds a full complement of Layer2 and Layer 3 management. Fault recovery, redundancy, security, access lists, PoE analytics and budgeting, alarms, performance monitoring, logging, and backup are just some of the protocols it hosts. It may be quickly configured using the serial console, command-line interface, or web GUI.

The reliability of the LMP-2004G-SFP switch is the best in the industry. It stands up to extreme temperatures, uncertain power, and electrical noise. Dual-redundant power inputs, surge protection, and a -40° to 75°C operating temperature range increase up-time. The fanless, metal enclosure with a standard DIN-rail bracket installs effortlessly in electrical panes and machines. A 5-year guarantee means you can rely on the LNP-2004G-SFP to be a workhorse in your critical network.
