GW-9000-6XH-X2 Teardown: A Slim 4×2.5G plus 2×SFP+ Switch

ACWiFi opened a GW-9000-6XH-X2 from 感闻科技, a slim metal switch with four 2.5G ports and two 10G optical ports.[4] The 2026-01-24 post is most useful for its power/DC and board-layout details rather than for a speed claim.[4]

Dimensions, power, and consumption

The adapter is rated 12V/1A.[4] Its DC plug is 5.5/2.5 mm, not the common 5.5/2.1 mm; a cabinet distribution block that only provides 5.5/2.1 mm will not fit.[4] ACWiFi measures roughly 1.3 W idle, 2.6 W with two 2.5G ports connected, and 4 W with all four 2.5G ports connected.[4]

The chassis is about 17.5 cm long and 7.3 cm wide, with side vents and mounting holes on the bottom.[4] The DC jack is on a different side from the network ports, which affects cable routing in a small cabinet.[4]

Internal hardware

The product label reads GW-9000-6XH-X2.[4] The teardown shows:[4]

• a metal chassis and two SFP+ slots;[4]
• a heatsink attached with thermal material, with the author describing the pad between the bottom and board as somewhat small;[4]
• an RTL8372N switch chip;[4]
• approximately 4 MB of flash.[4]

The source asks whether that flash could turn the device into a managed switch, but provides no firmware, flashing procedure, or evidence of a successful conversion.[4] I do not turn that question into an OpenWrt support claim.[4]

HomeLab implications

The slim chassis and low measured power suit a compact rack, while four 2.5G ports plus two SFP+ ports fit a topology with optical uplinks.[4] Before buying, I check the 5.5/2.5 DC connector, thermal clearance, and fiber cable length.[4] The measured consumption belongs to the inspected sample; SFP+ modules, optical load, and another revision can change it.[4]

ACWiFi also notes that a 5×2.5G plus 1×10G SFP+ switch is usually more expensive than a 4+2 design because it needs another 2.5G PHY chip.[4] That is a BOM/price explanation, not a throughput measurement.[4]

Teardown limits

The source does not publish forwarding tests, long-duration thermal data, an SFP+ compatibility table, management features, or OpenWrt firmware.[4] I therefore use the article to understand hardware, power, and layout only; software capability and real load must be tested separately.[4]

Conclusion

The GW-9000-6XH-X2's clear strengths are 4×2.5G + 2×SFP+, low idle power, and the familiar RTL8372N.[4] The 5.5/2.5 mm power connector, 4 MB flash, and lack of evidence for managed firmware are the three checks I would make before relying on it as long-term infrastructure.[4]
