Caution The 100 W PA and PMU weigh between 9.3 lb
(4.2 kg) and 15.4 lb (7 kg) each. Take care when hand-
ling these modules to avoid personal injury.
Important 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 mech-
anisms to prevent damage from overheating.
