Mercusys MS105GP 5-Port Gigabit Desktop Switch with 4-Port PoE+

The Mercusys MS105GP delivers reliable gigabit networking with integrated Power over Ethernet capability, combining data transfer and power delivery in a compact desktop form factor. This unmanaged switch provides four PoE+ ports and one standard gigabit port, supporting IEEE 802.3af/at compliant powered devices with up to 30W per port and 65W total PoE budget.

Full Gigabit Performance

All five 10/100/1000 Mbps RJ45 ports support auto-negotiation and Auto MDI/MDIX, delivering up to 2000 Mbps at full duplex. The store-and-forward switching method with 2K MAC address table ensures efficient traffic management, while 9KB jumbo frame support accommodates larger data packets for improved throughput.

Extended PoE Range

Standard PoE switches limit transmission to 100 meters, but the MS105GP's Extend Mode increases PoE distance up to 250 meters. This extended range capability makes it practical for deploying IP cameras, wireless access points, and other powered devices in locations where standard PoE reach falls short.

Isolation Mode for Network Segmentation

The one-click Isolation Mode divides traffic for specific ports, creating separate network segments that improve both stability and security. This feature prevents unnecessary broadcast traffic between isolated ports while maintaining connectivity to the uplink port.

Durable Metal Construction

The metal casing provides efficient heat dissipation, supporting continuous operation in temperatures from 0°C to 40°C. The robust enclosure protects internal components while enabling desktop or wall-mount installation options. Maximum power consumption reaches only 3.13W without connected devices, scaling to 75.15W with full 65W PoE load.

Plug-and-Play Operation

No configuration required—connect your devices and the switch automatically negotiates optimal connection speeds. IGMP Snooping V1/V2/V3 optimizes multicast traffic, while 802.3x flow control prevents packet loss during high-traffic conditions.
