I recently purchased a TL-SG1008 network switch and noticed in the instructions that it should be used/mounted with the bottom side down. However, I'm wondering if it's possible to mount the device vertically with the entry ports facing up and the power cable facing down for space-saving purposes. I can devise a solution to mount it firmly this way using the provided rack mounting points or bracket, which could also improve the air circulation. The only downside I see is that unused Ethernet ports facing up could accumulate dust. Would there be any issue with using the switch in this orientation as long as it's securely mounted? Thank you for any advice.
