Notice The cooling fans are mounted on the front panel and will only
operate when the panel is fitted correctly to the front of the subrack. To
ensure adequate airflow through the base station, do not operate it for
more than a few minutes with the front panel removed (e.g. for servicing
purposes). Both the PMU and PA modules have built-in protection
mechanisms to prevent damage from overheating.
