6 Maintenance
The base station is designed to be very reliable and should require little
maintenance. However, performing regular checks will prolong the life of
the equipment and prevent problems from happening.
It is beyond the scope of this manual to list every check that you should
perform on your base station. The type and frequency of maintenance
checks will depend on the location and type of your system. The checks and
procedures listed below can be used as a starting point for your maintenance
schedule.
Performance Checks We suggest you monitor the following operational parameters using the web
interface:
■ VSWR
■ DC input voltage, especially on transmit
■ receiver sensitivity
■ any temperature alarms.
These basic checks will provide an overview of how well your base station
is operating.
Reciter If an external frequency reference is not used, check UHF reciters for
frequency drift after 3 months’ service and annually thereafter. If the drift is
> 0.5 ppm, adjust the carrier frequency offset. For details, see the Help.
PA There are no special maintenance requirements for the PA.
PMU There are no special maintenance requirements for the PMU. However, we
suggest that you periodically check that the screws on the DC input
terminals are tight. They may work loose with thermal cycling. Also, if you
are using battery back-up, you should check the batteries regularly in
accordance with the manufacturer’s recommendations.
Ventilation The base station has been designed to have a front-to-back cooling airflow.
We strongly recommend that you periodically check and maintain the
ventilation requirements described in “Equipment Ventilation” on page 64
to ensure a long life and trouble-free operation for your base station.
Cooling Fans The cooling fans have a long service life and have no special maintenance
requirements. You can use the web interface to configure the base station to
generate an alarm if any of the front panel cooling fans fails. Refer to the
Help for more details.
