The MICROSENS MS440207PM-48G6+ is a managed 6-port Gigabit Ethernet micro-switch, specifically designed for use in compact installation scenarios. It features four PoE+ ports (10/100/1000T) and two SFP slots for 100/1000X connections, making it suitable for powering PoE-enabled end devices as well as integration into existing networks with optical or cable-based connections. The switch is designed for horizontal mounting and supports an operating voltage range of 44 to 57 VDC. It is equipped with a microSD slot and an RS-232 port (RJ-45), enabling configuration and diagnostics via serial interfaces.

Applications
This switch is particularly suitable for use in industrial environments, buildings with integrated security systems, or networks requiring a compact yet powerful network connection. The PoE+ function enables power delivery to IP cameras, access points, or other PoE-enabled devices via the network cable, simplifying installation and reducing the number of required power supplies. The horizontal mounting form makes it especially suitable for installation in device enclosures or enclosures where space is limited.

Functions and Features in Detail
The switch features four RJ45 ports, each supporting 10/100/1000 MBit/s and equipped with PoE+ (Power over Ethernet Plus). This allows power delivery to end devices with up to 30 W per port, depending on the PoE standard (IEEE 802.3at). The two SFP slots provide the option to integrate optical or cable-based connections for 100/1000X, increasing flexibility in network design. The managed function enables central control, monitoring, and configuration via network protocols such as SNMP, which is essential for professional network environments.

Technology Explained Simply
The PoE+ technology enables the transmission of power and data over a single Ethernet cable, allowing the installation of end devices such as IP cameras or access points without additional power supplies. The operating voltage of 44 to 57 VDC is typical for industrial or specialized network applications, where stable and robust power supply is required. The microSD slot is used for storing configurations, logs, or firmware updates, while the RS-232 port (RJ-45) provides a serial configuration option, which is particularly useful during commissioning or troubleshooting.

Compatibility and Accessories
Various accessories are available for use with this switch, including a TP(RJ45) POE tester for checking PoE connections (at/af, Endspan/Midspan) and a M45 mounting kit universal for E2 device enclosures, consisting of a mounting adapter and a cover frame in RAL9010. These components support installation and maintenance of the switch in standardized mounting situations.

Mounting and Installation
The switch is designed for horizontal mounting, making it especially suitable for installation in device enclosures, enclosures, or other flat mounting surfaces. Mounting is done using the integrated mounting elements, with the exact mounting method depending on the specific installation scenario. Using the M45 mounting kit enables standardized installation in E2 device enclosures.

Operational Advantages
The combination of PoE+, managed function, SFP slots, and serial interface offers high flexibility and control over the network. The PoE+ function reduces the need for additional power supplies, while the managed function enables centralized network management. The horizontal form factor and support for 44 to 57 VDC make the switch particularly suitable for industrial or specialized applications where robustness and reliability are required.
