I just fully deployed my CSS326-24G-2S+RM in my network and it’s totally doing good but I noticed that the Switch gets hot at 70-78 degree Celsius. I don’t have any cooling fans to alleviate the whole network, should I get worried about it?
If that’s a non-air conditioned room, that is pretty normal. I just looked at mine (same switch type) and they vary from about 50 (in an air conditioned data cabinet) up to 72 (in my not air conditioned family room - currently 27C). Also varies a little depending on what SFPs you have plugged in. The high speed Ethernet SFPs make a lot more heat than optical SFPs.
I used AOC but not from official brands and more like something made in China. The brand is non-existent but it showed up as Huawei with 40mm Copper cable which is false but it works fine in 10G Link Speeds.
