QNAP QSW-M408-4C Taredown

I recently replaced my QNAP QSW-M408-4C with a MikroTik CRS312-4C+8XG, and I thought it would be interesting to document the taredown process. The QNAP switch has 4x 10G SFP+/RJ45 combo ports and 8x 1Gb RJ45 ports, making it a decent switch for a home lab, but I found the UI to be very over simplified and lacking in features compared to the MikroTik switch.

Tools Required

  • Phillips head screwdriver
  • Plastic spudger (optional)

Taredown Steps

  1. Remove the screws: There are 6 screws on the bottom of the switch, 4 of which are under the rubber feet, and another is under the manufacture date sticker. You will need to peel off the rubber feet and remove the screws using a Phillips head screwdriver. Underside with screws highlighted

  2. Remove cover: The back of the switch should now be loose, you can carefully lift it slightly, but the front is still held in place by clips. Removing the cover

  3. Release the clips: Use a plastic spudger or your fingers to gently release the clips on the front of the switch. Releasing clips on the front

  4. Remove the cover: Once the clips are released, you can fully remove the cover. Removing the cover Side note: There’s a USB header along the top of the PCB, seems interesting…

Assembly Notes

The assembly is the mostly reverse of the disassembly, but there are a few things to keep in mind:

  • Be sure to push the cover back on firmly, and ensure the SFP+ ports are aligned properly as the metal bits can catch on the cover. Reassembling the switch

  • You may need to press down on the front clips to ensure they snap back into place. Reassembling the front clips

I hope you found this taredown guide helpful!
