What you'll notice
The switch reboots or fails on hot afternoons; the cabinet smells warm; ports fail one by one over months.
Why it happens
A sealed enclosure with no airflow, direct sun on the cabinet, or a switch running near its limits in a hot ceiling.
How we fix it
Ventilation, relocation or a fan kit — heat is the primary killer of network hardware, and fixing it costs far less than replacing switches annually.
Still not working?
