The MICROSENS MS400890MX-V2 is a 25-port Gigabit Ethernet industrial switch with PoE+ functionality, specifically designed for use in demanding industrial and professional networks. The device offers full Gigabit performance and supports the Energy Efficient Ethernet standard, reducing energy consumption and operating costs. With a total of 25 Gigabit Ethernet ports, including 16 PoE+ ports and 8 LWL combo ports, it enables flexible network integration. PoE+ support according to IEEE 802.3at ensures efficient power delivery over the network cable, with the standard version providing a power budget of 240W. A special variant with a total power output of 480W is also available to meet higher requirements.

Applications

The switch is designed for use in industrial environments where high reliability, robust construction, and operation under extreme temperatures are required. It is suitable for applications such as factory networks, automation systems, surveillance installations, or critical infrastructures, where continuous network availability is essential. The integrated MICROSENS ring function ensures high fault tolerance with short switchover times in the event of a network failure.

Functions and Equipment in Detail

The device features 17 RJ45 ports for 10/100/1000T connections, of which 16 are PoE+ ports. The 8 LWL combo ports can be used either as SFP slots for fiber optic cables or as 10/100/1000T ports, enabling flexible adaptation to various network architectures. An integrated PD+ port is also available to power external devices. Management functions include web, SSH, and SNMP interfaces, as well as the MICROSENS NMP software, which enables intuitive configuration and monitoring of the switch.

Technology Explained Simply

The switch operates with the Full Gigabit Ethernet standard and supports Energy Efficient Ethernet, meaning power supply is adjusted to the actual network load to save energy. PoE+ technology (Power over Ethernet Plus) enables power delivery to end devices such as IP cameras or access points over the network cable, eliminating the need for separate power supplies. The redundant power supply with two inputs for 24 to 57 VDC increases operational reliability, as a second input takes over in the event of a power failure.

Compatibility and Accessories

The switch is equipped with an integrated DIN rail adapter, enabling mounting on a DIN rail. The MICROSENS ring function supports redundant network structures, ensuring high availability. Security functions include SSH, HTTPS, SNMPv3, Port Security according to IEEE 802.1x, and full RADIUS NAC compatibility to prevent unauthorized access. The operating temperature range extends from -40°C to +75°C, enabling use in extreme environments.

Mounting and Installation

The switch is delivered in a robust, compact, and fanless VA housing designed for use in demanding environments. Mounting is done via the integrated DIN rail adapter, with mounting hardware included in the delivery. The installation manual supports setup and configuration of the device.

Operational Advantages

The combination of PoE+ functionality, redundant power supply, extended temperature tolerance, and integrated ring function provides high operational reliability and safety. The fanless design reduces maintenance requirements and prevents dust accumulation. Management and security functions enable centralized monitoring and control of the network, making network administration more efficient. The integrated SD card and USB port support additional functions such as firmware updates or data logging.
