The MICROSENS MS453502PM-G6+ is a 6-Port Gigabit Ethernet Switch with integrated power supply, specifically designed for use in industrial and professional networks. The device features five RJ-45 ports for 10/100/1000Base-T connections, four of which are equipped with PoE+ (Power-over-Ethernet plus) and can deliver up to 30 W per port. One additional port serves as an SFP-Uplink for fiber optic connections in the 100/1000Base-X standard. The switch is fully managed and offers extensive network management functions, including SNMP, Web interface, Telnet, SSH, and a central management platform (NMP). Device control is performed via a Linux operating system with an 800 MHz ARM CPU, ensuring fast system startup and high processing performance.

Applications
This switch is suitable for applications requiring a reliable, fanless, and compact network connection, such as in office and industrial facilities, surveillance systems, or cabling networks with PoE end devices like IP cameras or access points. The integrated power supply operating on 230VAC and the compact form factor (220 x 40 x 110 mm) allow for flexible desktop or wall mounting. The Energy Efficient Ethernet function (IEEE 802.3az) reduces power consumption per port by up to 50 %, depending on network load.

Functions and Features in Detail
The switch supports Layer-2+ Store-and-Forward switching with full wire-speed performance and is non-blocking. The maximum number of MAC addresses is 8,192, with automatic learning and aging enabled. Jumbo frames up to 10,240 bytes are supported, enhancing the efficiency of large data packet transmission. The PoE+ ports are designed for powering end devices according to IEEE 802.3at, with the switch’s total power output limited to a maximum of 65 W. The PoE function can be individually configured per port via the management software.

Technical Explanation
The integrated management agent enables configuration and monitoring via various protocols: Web interface (HTTP/HTTPS), Telnet, SSH, and SNMP (versions v1, v2c, v3). Firmware and configurations can be stored and executed directly on the device via FTP, SFTP, or TFTP. An optional microSD slot allows the use of a removable memory card for firmware updates, configurations, and scripts. The file system is fault-tolerant and can optionally be encrypted. An RS-232 console port (mini-USB) provides a direct interface for maintenance and diagnostics.

Compatibility and Accessories
The switch is compatible with standard CISCO switches, particularly regarding QoS, VLANs, CDP, and RSTP. Available accessories include SFP transceivers for multimode fiber (850 nm, LC connector), enabling uplink connections via fiber optic cable. A TP(RJ45) PoE tester for at/af standard is also available. The devices are designed for use in networks with PoE end devices, with PoE power per port and total switch power clearly defined.

Mounting and Installation
The device is fanless and thus suitable for use in environments where noise must be avoided. Mounting is either on a desktop or on the wall using an optional metal wall bracket (for variants with external power supply). Power supply is provided via the integrated 230VAC power unit with a power rating of 65 VA. Connections are clearly labeled, and the Auto-MDI/MDI-X function ensures compatible cabling with standard patch cables.

Operational Advantages
The switch offers high reliability due to its monolithic construction and fanless design. Integrated management functionality enables centralized network control, reducing maintenance effort. Support for VLANs, QoS, Port Trunking, and RSTP (Rapid Spanning Tree Protocol) ensures a flexible network architecture. The use of Jumbo frames and Energy Efficient Ethernet optimizes network performance and reduces energy consumption.
