The MICROSENS MS440203PM-48G6+ is a Gigabit Ethernet installation switch for horizontal mounting in standard network outlets. It features six ports, five of which are RJ45 connectors configured as Power-over-Ethernet+ (PSE) and thus can supply power to end devices such as IP cameras or access points. The sixth port is a 1000LX uplink with ST connector for single-mode fibre, operating in the 1310nm range, enabling connection to a central network or another switch via fibre optic cable. The ports support data rates of 10/100/1000 MBit/s, with the uplink port also usable as a downlink for 10/100/1000T.

Applications
This switch is designed for use in structured cabling systems in offices, industrial facilities, or buildings with high requirements for network security and availability. The horizontal mounting feature allows integrated installation in standard network outlets (45x45 mm), resulting in a visually clean and space-efficient cabling setup. The PoE+ function is particularly suitable for powering IP phones, surveillance cameras, or WLAN access points via the network cable.

Functions and features in detail
The switch is manageable and offers access via web interface, Telnet, and SNMP. Optionally, NMP software can be used to extend network management capabilities. Support for VLANs enables logical separation of network segments to improve security and performance. QoS (Quality of Service) functions ensure prioritisation of data traffic, for example for VoIP or video streaming applications. The integrated security function protects against unauthorised access and unauthorised use of network resources.

Technology explained simply
Power supply is via a 44 to 57 VDC connection, allowing flexible integration into existing power supply systems. PoE+ technology delivers up to 30 W per port (according to IEEE 802.3at/af), enabling even power-intensive devices to be operated. The uplink port with ST connector and 1310nm wavelength is designed for single-mode fibre optic cables, enabling high data rates over long distances. The horizontal mounting size of 45x45 mm fits standard network outlets and allows clean integration into existing installations.

Compatibility and accessories
For use of the switch, suitable mounting kits such as the M45 mounting kit universal for E2 device outlet are recommended to ensure secure installation in the outlet. To test PoE functions, a TP(RJ45) POE tester can be used to check power delivery over the network cable. Compatibility with other network devices is ensured by support for standard protocols such as SNMP, Telnet, and web management.

Installation and mounting
The switch is mounted horizontally in a standard network outlet. Mounting is done using the integrated mounting elements, and using a suitable mounting kit facilitates the installation. Power supply is via the 44–57 VDC connection, which must be connected to an appropriate power source. Network cabling is done via the RJ45 ports and the ST fibre cable for the uplink.

Operational advantages
The switch provides a compact, integrated solution for use in structured cabling systems. The PoE+ function reduces the need for additional power supplies for end devices. Management functions enable central network monitoring and control. Support for VLANs and QoS ensures optimised network performance and enhanced security. The horizontal mounting size allows clean and space-efficient installation in existing cabling systems.
