4×2.5G RJ45 + 2×10G SFP+ switch

The TelDaykemei Hi-K0402WS is a stackable Ethernet switch with four 2.5G RJ45 ports and two 10G SFP+ optical uplinks. It targets home labs and small offices that need multi-gigabit connectivity for NAS, workstations or 2.5G access points. The switch supports IEEE 802.3, 802.3u, 802.3x, 802.3ab and 802.3bz standards for broad device compatibility.

Sustained-load behaviour

A store-and-forward mechanism with high-capacity internal cache reduces forwarding latency under continuous traffic. All six ports deliver non-blocking wire-speed forwarding at a packet rate of 44.64 millionths of a second. The 2.5G RJ45 ports handle 2500 Mbps links while the SFP+ slots accept 10G optical modules for uplink aggregation.

Pre-order checklist

Verify that your SFP+ modules match the 10G optical interface and that cabling supports 2.5GBASE-T or 10GBASE-R distances. Confirm the stackable form factor fits your rack or shelf layout. Ensure connected endpoints negotiate 2.5G or 10G speeds; legacy 1G devices will operate at lower rates.

Questions about this item

Does the Hi-K0402WS run silently or need a fan when all four 2.5G ports and both 10G SFP+ slots are active all day?

The switch is fanless, so it operates silently even under continuous load across all six ports.

Which SFP+ transceivers or direct-attach cables must I already own to use the two 10G uplink slots on this switch?

The 10G SFP+ slots accept any standard SFP+ module or DAC; you supply the optics or copper cables that match your link distance and fibre type.

Will my existing 1Gbit desktop and 100Mbit IP camera connect automatically to the 2.5G RJ45 ports on the Hi-K0402WS?

Yes, each 2.5G port auto-negotiates down to 1G or 100M speeds, so legacy devices work immediately without configuration.
