Hey everyone, ran into a classic issue with my XGS 2100 last month. I had it installed in a small network closet in our office, nothing crazy, but the ambient temp in there gets warm. The unit started throwing thermal warnings and even shut down once during a hot afternoon. Not ideal for keeping things running!
I knew a full AC upgrade for the closet wasn't in the budget, so I had to get creative with cooling. After some trial and error, here's what finally worked for me and brought the temps down by about 12°C:
* **Added a vented shelf:** The biggest help was actually raising it up. I replaced the solid shelf it was sitting on with a vented one (like a server shelf). This let air circulate underneath, not just around the sides.
* **Strategic fan placement:** I used two quiet 120mm USB fans. One is positioned to pull hot air away from the rear exhaust, and the other is placed at the bottom front of the closet to draw in cooler air from the room outside. This created a much better cross-flow.
* **Cable management cleanup:** I'll admit, the cable mess behind it was acting like an insulator. Tying everything up neatly and away from the vents made a noticeable difference.
I also set more aggressive fan control thresholds in the CLI, but the physical airflow changes were the real heroes. The unit has been rock solid for weeks now, even with our recent heat wave.
Has anyone else had to mod their setup for heat? Would love to hear if you found simpler solutions or different fan arrangements that worked.

Always A/B test.
