TP-Link Omada 5-Port 2.5G Desktop Switch

TP-Link 5-Port 2.5G Desktop Switch (TL-SG105-M2) - Local Warranty

The TL-SG105-M2 puts five 2.5GBASE-T ports into a fanless desktop case, giving two and a half times Gigabit throughput over the Cat5e already in the wall. Every port auto-negotiates 100M, 1G or 2.5G, so it drops into an existing network without reconfiguration - a direct answer to NAS, Wi-Fi 6/7 access points and workstations that have outgrown a 1 Gbps link.

Five 2.5GBASE-T Ports, No Recabling Required

All five ports run 100Mbps, 1Gbps or 2.5Gbps with auto-negotiation and Auto MDI/MDIX, implementing IEEE 802.3bz - the standard written specifically so multi-gigabit speeds run over existing Cat5e and Cat6 rather than requiring a recable to Cat6A. That is the practical case for this switch: a NAS, a 2.5G Wi-Fi access point and a couple of workstations get 2.5x the bandwidth on the cabling already installed, and any device that only speaks Gigabit simply negotiates down and keeps working.

25 Gbps Switching Capacity With an 18.6 Mpps Forwarding Rate

Switching capacity of 25 Gbps covers all five ports running 2.5Gbps in both directions at once, so the fabric is non-blocking and no traffic pattern can saturate the backplane. The 18.6 Mpps packet forwarding rate sustains line rate at minimum frame size, which is what matters for the many-small-packets workloads that multi-gigabit links are usually bought for. A 16K MAC address table is generous for a five-port switch, so it holds up behind a busy segmented network rather than flooding.

10 KB Jumbo Frames and a 1.5 Mb Buffer for NAS Transfers

Jumbo frame support up to 10 KB lets a NAS or backup host move data in far fewer, larger frames, cutting per-frame overhead on exactly the large sequential transfers that justify 2.5G in the first place. The 1.5 Mb packet buffer absorbs the bursts those transfers produce instead of dropping frames, and store-and-forward switching validates each frame before it is sent on. IEEE 802.3x flow control signals congestion back to the sender, and 802.1p/DSCP QoS lets tagged latency-sensitive traffic take priority.

Fanless, Silent, and Sized for a Desk

The case measures 209 x 126 x 26 mm and has no fan, so it is silent and can sit on a desk, on a shelf beside a NAS, or behind a monitor without adding noise to a working space. Power comes from an external adapter supplying 12VDC at 1A; maximum consumption is 12.11W with heat dissipation of 41.32 BTU/h, which is higher than a Fast Ethernet switch because driving five 2.5G PHYs genuinely costs more power. One system power LED plus a Link/Act LED per port give at-a-glance status.

Unmanaged: No VLANs, No PoE, No Controller

There is no web interface, no VLAN configuration, no SNMP and no PoE, and this is not an Omada SDN device - it cannot be adopted into an Omada Controller. The QoS and flow control listed above are hardware behaviours, not configurable policy. Where a project needs VLAN segmentation, PoE for access points, or central management across a site, SourceIT can quote the Omada smart or managed 2.5G ranges instead.
