The Spec is pending and needs your requirements

The problem is really "heat" + "port density". There are many ports, if you line them up, you are wider than 10 inch. If you stack them, then heat becomes an issue. The 10g switch for example, it wiill need to have fans and a much bigger power unit to push 400+ watts ... you can't really make that into a 10 inch.
And yes, we fully understand the 10 inch look, the gold pro fit in a 10inch (wide) rack.

Ryan, I've scoured the switch mine-fields too, NetGear, QNAP, UniFi, ... generics. I narrowed the contender for a 10GbE / RJ45 / SPF+ option to the same model: QNAP QSW-M3216R-8S8T-US. At some point I need a POE switch to run a few things but that's not as imperative. I've kicked my 10GbE can" down the road" since Summer 2025. I am unsure how much longer I can hold out for a Firewalla-based eco-system switch. Each player has strengths.

I have had several 8 port sfp+ switches which would fit in a 10in rack and have had all of the ports running with SFP rj-45 transceivers with no issues. Also, I have several 8-port SFP+ from mikrotik which also meet this requirement and have fully loaded with RJ-45 transceivers. Not sure what port density you are looking for here as originally I asked about the target switches and they were going to be 5-8 ports of 10gb. Of course if you go to 12-24 port then yes 10 inch is an issue as well as needing fans and a higher power consumption.
Mikrotik CRS309 8 port SFP+ 10gb and no fans would draw about 55W with all SFP+ ports full with the higher wattage transceivers and would be pushing the limits of 57W power supply fully loaded. But with the lower power transceivers would be about 35W. Note: That this switch is just slightly over 10" but can fit in a 10" rack with 3D printed ears.
However, the mikrotik CRS326-24S+2Q+RM has 24 SFP+ 10gb ports, 3 fans, 2 redundant power supplies would be the following:
- Switch base draw: ~30-35W
- 24x copper SFP+ transceivers: 24 × 3-5W = 72–120W
- 2x QSFP+(40gb) (if populated): add another 3-10W each
- 2x 130w power supplies redundant
So fully loaded that is like 175-180W meaning like a 200-225w power supply not 400+. I use >2w RJ45 transceivers which brings that down to about 103W totally loaded.
Heat is an issue but with the lower power SFP+ RJ-45 transceivers that is less of an issue. Even in the lower end 8-port SFP+ switches with the lower power RJ-45 transceivers I did not have a heat issue. Also, for 10" rack I would use DACs not transceivers which is even less power and less heat.
I use 19" racks so I don't have this issue but for your market it would seem a 10" footprint would be better served for at least one model of the switch. Along with a rack kit for both 19" and 10" racks.
