Mercusys MS112GMP 12-Port Gigabit Desktop Switch with 8 PoE+ Ports

The Mercusys MS112GMP is a high-performance 12-port Gigabit desktop switch engineered to streamline network connectivity and power delivery. Featuring 8 Gigabit PoE+ ports, this device simplifies installations by transmitting both data and electricity through a single Ethernet cable, making it an essential component for modern home and small office networks. With its robust switching capacity and versatile uplink options, including SFP slots, it ensures reliable and high-speed data transmission for demanding network environments.

Advantages

This switch offers significant flexibility through its PoE+ support, providing up to 30W per port with a total power budget of 110W, which is ideal for powering IP cameras, access points, and VoIP phones. The inclusion of an Extend Mode allows for data and power transmission over distances of up to 250 meters, overcoming standard cable limitations. Enhanced security and performance are achieved through the Isolation Mode, which separates traffic between ports, while the Priority Mode ensures critical devices connected to ports 1-2 receive stable bandwidth. Furthermore, the PoE Auto Recovery function maintains network uptime by automatically restarting unresponsive connected devices, and the fanless design ensures silent operation in any environment.

Suitable for

• Powering and connecting IP security cameras
• Deploying wireless access points in offices or homes
• Expanding wired network capacity for desktop computers and printers
• Creating secure, isolated network segments for specific devices
• Long-distance network installations requiring power over Ethernet

When it may not be suitable

This switch is not intended for large-scale enterprise environments that require managed features like VLAN tagging, SNMP monitoring, or complex traffic shaping. Additionally, it may not be suitable for high-density deployments where the 110W total power budget is insufficient to support multiple high-power consumption devices simultaneously.

Key specifications

• 8 x 10/100/1000 Mbps PoE+ RJ45 ports
• 2 x Gigabit RJ45 uplink ports and 2 x Gigabit SFP slots
• Total PoE budget of 110W with up to 30W per port
• Switching capacity of 24 Gbps
• Extend Mode support up to 250 meters
• Fanless design for silent operation
• Dimensions: 209 x 126 x 26 mm

How to use

The Mercusys MS112GMP is designed for immediate deployment using a plug-and-play approach. Simply connect the provided power adapter to the switch and a wall outlet, then connect your network devices to the RJ45 ports using standard Ethernet cables. For devices requiring power, ensure they are connected to ports 1 through 8. If you need to extend the range beyond 100 meters, toggle the Extend Mode switch on the device. The switch automatically detects and negotiates the speed and power requirements of connected devices without the need for manual configuration.

What to consider before purchase

• Verify that your connected devices support the IEEE 802.3af/at standard for PoE.
• Ensure the total power consumption of all connected PoE devices does not exceed the 110W budget.
• Check if your network infrastructure requires SFP fiber connectivity or if standard RJ45 uplinks are sufficient.
• Confirm the physical space requirements for the desktop form factor.

Usage recommendations

For optimal performance and longevity, ensure the switch is placed in a well-ventilated area, even though it is fanless, to allow for natural heat dissipation. When using the Extend Mode, ensure you are using high-quality Cat5e or Cat6 cabling to maintain signal integrity over longer distances.
