Question Fitting TP-Link Omada switch in 10" rack with only 2mm left - - - will it overheat ?

[wondra2]

I would like to get an Omada switch(es) with at least 12 ports for a small 10" rack, there is the TP-Link TL-SG2016P that seems to be best fit. However, the trouble is that the width of the switch is 286mm, while the internal space behind rails I measured in the 10" rack is just 288mm, only 2mm wider. I can get one to try and see if it fits, that is not a problem, however:

The question is, even if it fits, is it safe to operate a switch with virtually no space on the sides? Will I run into overheating problems, can I stress test it, create max PoE draw somehow?
Is there a better solution, another Omada switch perhaps? I ve found a smaller SG2008P which I could get two of, however it does not seem to be suited for rack placement (ports and power in are on the back side while status LEDs on the front which would make patching a nightmare.
Any help how to get out of this predicament will be appriciated.

It is going to depend on how much PoE load you plan to put on it. With none it likely only uses something small like 25 watts so you can just add the power of each poe device you plan to use.
I would not suspect it will get real hot since a lot of the heat will come out the metal case on the top and bottom. I assume you are going to jury rig some shelf or something since I don't see rack mount kits for that switch.

There isn't a fan on that switch that I can see in the specs so I am not sure if it matters a lot if you were to somewhat block the vents on the side.

Yes! I will flip standard U shelf up side down and drill screws in it as back side stop, it is perforated so there will be some air access from both top and bottom.
I plan to use some of the PoE budget - around half I think: two APs and an IP cam, possibly Raspberry Pi with some small IoT devices, but they shouldnt need much. Should never be above 100W.

I doubt you have a issue most these device will actually have a fan if they have heat issues.

I am not sure what the purpose of side vents would be. Its not like the heat will cause the air to flow from side to side. If it had a vent in the top in theory it could pull air in the side and come out the top with no fan but without a top vent it will just heat the top of the case. From the photos I found it seem it only has those small vents on the side.

I suspect since the surface area of the top of the switch is actually fairly large it will be able to radiate enough heat. In addition since it uses a power block you will not have the heat used when it converts ac power to dc inside the switch case.
