Product overview

The TP-Link TL-SG105-M2 is an unmanaged 5-port 2.5G multi-gigabit desktop switch designed for SMB environments. It features five 2.5Gbps RJ45 ports supporting 100Mbps/1Gbps/2.5Gbps auto-negotiation and Auto-MDI/MDIX, delivering 25Gbps switching capacity and 18.6 Mpps forwarding rate. With a 16K MAC address table, 1.5Mb packet buffer, and 10KB jumbo frame support, it handles high-bandwidth demands efficiently. Advanced features include 802.3X flow control and 802.1p/DSCP QoS for optimized traffic management using store-and-forward transmission. The fanless steel case ensures silent operation, with dimensions of 8.2 x 4.9 x 1.0 in and max power consumption of 12.11W from a 12VDC/1A adapter. Compliant with IEEE 802.3, 802.3u, 802.3ab, 802.3x, 802.1p, 802.3bz standards and CE, FCC, RoHS certifications, it suits small offices, home labs, and high-speed NAS/server connections without Cat6 upgrades.
