4×2.5G + 2×10G SFP+ Switch

The Dahua Da-K6402W is an unmanaged Ethernet switch with four 2.5G Base-T RJ45 ports and two 10G SFP+ uplink ports. It supports 100, 1000 and 2500 Mbps link speeds and delivers a 60 Gbps switching capacity. The fanless metal chassis runs silently in home or office environments.

Sustained load behaviour

The fanless design dissipates heat passively through the metal enclosure, so acoustic output stays at zero under continuous traffic. LED indicators show the active rate on each port, with the left LED signalling 2.5G and the right LED signalling 100 or 1000 Mbps. No configuration is required to maintain wire-speed forwarding across all six ports.

Practical limits of the interface

The two 10G SFP+ uplinks accept compatible transceiver modules for fibre or direct-attach copper links up to 10 Gbps. The four RJ45 ports auto-negotiate down to 100 or 1000 Mbps when connected to legacy gear, but they cannot exceed 2.5 Gbps. Builders needing more than four 2.5G copper ports or PoE power must look elsewhere.

Questions about this item

How noisy or hot does the fanless Da-K6402W get when it runs 24/7?

The metal fanless design makes the Da-K6402W silent and lowers energy consumption during continuous operation.

What cables or modules do I need to use the 10G SFP+ uplinks on this switch?

You must supply compatible 10G SFP+ transceiver modules and the matching fibre or direct-attach cables for the two uplink ports.

Will my 100 Mbps and 1 Gbps devices work alongside the 2.5G ports on the Da-K6402W?

Each RJ45 port auto-negotiates 100, 1000 or 2500 Mbps, so legacy 100 Mbps and 1 Gbps gear connects without configuration.
