KeepLiNK KP-9000-9XHML-X: a lightly managed 8-port 2.5G switch

The useful detail in the KP-9000-9XHML-X is not only its eight 2.5G ports, but how power changes with active ports. In a HomeLab, that affects heat and always-on cost.

What the sample tells us

The source reports: 12V/1.5A; 1.8W idle; 4.8W with four ports; 7.9W with eight ports; RTL8373N; RTL8224N; 2MB flash. These are observations from the sample and conditions documented by ACWiFi, not a guarantee for every production batch.

How to read the hardware

I do not infer aggregate throughput, temperature, or OpenWrt support from a chip name alone. For a switch, separate port count, uplink type, and simultaneous forwarding. For a router, separate the radios, CPU, memory, flash, and hardware revision. When the source does not measure something, I leave it unknown instead of filling the gap with a guess.

Có hợp với HomeLab không?

Is it a good HomeLab fit?

This sample is worth considering only for the capabilities documented by the source. Before buying, verify the revision, included power supply, port types, and firmware. If SFP+/optical modules matter, test the exact module or consult a compatibility list; one working module does not prove that another will work.

Limits of the teardown

This is an analysis of one disassembled sample, not an independent AIoT measurement. Another revision or batch may use a different PCB, chip, FEM, flash, or firmware. I do not rehost the source images or turn a teardown observation into an OpenWrt-support claim.
