6 Replacing Modules
Caution The TB8100 PA and PMU weigh between 4.6kg
(10.1lb) and 5.8kg (12.8lb) each. Take care when
handling 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.
6.1 Saving the Base Station’s Configuration
Before replacing a module in the TB8100 BSS, you should decide whether
you need to save its configuration data. If you are unsure whether you have
a record of the configuration, use the Service Kit to read the base station and
save the configuration file before removing any modules. Once you have
replaced the module, you will be able to restore the original configuration
by programming the saved configuration back into the base station. If one
or more of the modules is faulty, you may be unable to read the base station.
In this case, you will have to restore the configuration from a back-up file.
Refer to the Service Kit and its associated documentation for more
information.
