Your PoE load has grown. More cameras, more access points, more sensors on the line. The 240W supply is running hot and you can feel it struggling at peak draw. You need headroom without ripping out the whole switch.
The D-Link DIS-N480-48 doubles the output to 480W at 48–55V DC, purpose-built for DIS-series industrial switches. Same 70°C operating rating, so it performs in enclosed and outdoor environments where a consumer PSU would throttle or shut down.
If your network's outgrown its power budget, this is the fix that doesn't mean replacing the switch.
