Alta Labs already have a fanless 16-port POE switch in their offerings. However, its size prevents it from being placed on a desktop for users who don’t have or want a rack in their house. I know the S8-POE is smaller enough for this purpose, but for some, 8 ports are just not enough. 2 WiFi access points, a couple of POE security cameras, ethernet ports for the TV, media player, gaming console and NAS, and you’re starting to run out of ports for your study. You also need a port for your router.
In my case, I have my router, switch and ISP issued modem sitting on an IKEA 4x1 Kallax shelving unit (KALLAX Shelf unit, white, 16 1/2x57 7/8" - IKEA) in my study. The S-16 POE, at 441.5 mm wide, is just too wide to fit on the shelf. So, a desktop version that is no wider than 280 mm would be ideal in my opinion.
Other than the Unifi Lite 16 POE (USW-Lite-16-POE), there aren’t too many fanless 16-port POE switches with VLAN capabilities on the market right now. This could be an opportunity to capture some market share.
