D-Link 5-Port 2.5G Multi-Gigabit Desktop Switch Unmanaged L2 5x2.5G Ports

The D-Link DMS-105 is a compact unmanaged Layer 2 desktop switch with five 2.5 Gigabit Ethernet RJ-45 ports. Designed to increase network throughput for homes and small offices, the switch offers multi-Gigabit speeds on every port, a switching capacity of 25 Gbit/s and a MAC address table supporting up to 4000 entries. Its metal, fanless housing and energy-efficient features enable silent operation and reliable performance in a small form factor.

Advantages

All five ports support 2.5Gbps Multi-Gigabit Ethernet for faster file transfers and reduced network bottlenecks. The device is plug-and-play and requires no configuration, enabling instant network expansion. Built-in QoS, Flow Control and IGMP Snooping help prioritise traffic and reduce unnecessary multicast load, while Link Status detection and IEEE 802.3az support save power by disabling inactive ports. The compact metal housing improves heat dissipation and provides durable, silent operation without a fan.

Suitable for

• Upgrading a home network to support Wi‑Fi 6 access points
• Connecting NAS, servers and desktop computers for faster local transfers
• Small office or home office network expansion without configuration
• IPTV and multimedia streaming environments requiring multicast optimisation

How to use

Place the DMS-105 on a stable surface or mount it as needed, connect the switch to your router, modem or core network using a standard RJ-45 cable, then connect devices (PCs, NAS, APs) to the remaining 2.5G ports. The switch operates as plug-and-play so no configuration is required. Ensure connected cables and devices support the intended speeds to benefit from Multi-Gigabit throughput.

Recommendations

For best results use CAT5e or higher-rated Ethernet cables and connect Wi‑Fi 6 access points or NAS devices to the 2.5G ports to avoid creating bottlenecks. Place the fanless metal unit in a ventilated area to help heat dissipation and allow Link Status power-saving features to manage inactive ports.
