The MICROSENS MS453501PM-48G6+ is a managed 6-port Gigabit Ethernet mini-switch with integrated PoE function (Power over Ethernet). It is designed for use in networks where multiple end devices such as IP cameras, access points or telephone systems are to be supplied with power and data via the network cable. The switch features five 10/100/1000T-TC ports and one SFP slot for fibre optic connections in the Gigabit range. The PoE function is available on four of the five TC ports, enabling up to four PoE-compatible devices to be directly connected and powered. Power supply is via 230VAC, with an integrated power supply unit of 65VA included in the delivery scope.

Applications
This switch is suitable for small to medium-sized networks in offices, industrial facilities or outdoor environments where a compact yet powerful network connection is required. The combination of Gigabit connections, PoE and an SFP interface makes it particularly suitable for applications requiring a flexible and scalable network infrastructure, for example in security or surveillance systems with IP cameras or in industrial environments with distributed device connections.

Functions and Equipment in Detail
The switch is managed, meaning it can be controlled and monitored via a web interface, CLI or SNMP management. This allows configuration of VLANs, QoS settings, port security and other network parameters. An integrated microSD slot enables storage of configurations, logs or firmware updates. Additionally, an RS-232 port (implemented via mini USB) is available for serial configuration or maintenance purposes. The PoE implementation complies with standards 802.3af/at, ensuring compatibility with a wide range of PoE devices.

Technology Explained Simply
The five RJ45 ports support data rates up to 1000 Mbit/s (Gigabit Ethernet) and are equipped with PoE, with four ports providing PoE. The SFP slot enables connection via fibre optic cables with a range of up to 550 metres (depending on the transceiver used), making it suitable for wired connections over longer distances. Power supply via 230VAC with integrated power supply ensures stable operating voltage. The managed function allows central management of the switch, monitoring of port status and adjustment of network settings, which is particularly important for critical applications.

Compatibility and Accessories
The switch is compatible with SFP transceivers operating in the Gigabit range, such as multimode transceivers with 850 nm wavelength. Suitable accessories include PoE testers for checking power supply and SFP modules for fibre optic connections. The use of SFP modules extends the range and flexibility of the network, especially in environments where copper cables are insufficient or impractical.

Mounting and Installation
The switch is compact and can be placed on a desk or mounted in a 19-inch rack, although the mounting options are not described in detail. Installation is carried out via the network connections and power supply. Configuration is performed via the web interface, CLI or the RS-232 port. The integrated power supply simplifies installation as no external power supply unit is required.

Advantages in Operation
The switch offers high flexibility through the combination of PoE, Gigabit connections and an SFP interface. The managed function enables central network management, simplifying maintenance and troubleshooting. The integrated power supply reduces the number of required components. Using PoE reduces the need for separate power supplies for end devices, simplifying installation and reducing the number of cables. Support for VLANs and QoS enables targeted network control, especially in environments with high demands on bandwidth and prioritisation.
