Planned Maintenance Inspection (PMI)
In order to assist maintainers of Motorola Dimetra products, Motorola publishes advice for recommended.
Planned Maintenance Inspections (PMI). For each Motorola Part Number, the Inspection Schedule indicates
whether any PMI action is required/recommended, the regularity of the recommended/required action,
and a brief description of the activity. The Inspection Schedule also indicates Motorola's recommended
PMI testing activities that should be carried out as part of the PMI Schedule.
The PMI Inspection Schedule should always be read in conjunction with the relevant Motorola or
Motorola 3rd party suppliers’ Standard Product Manuals and any Technical Information Bulletins
(TIBs), where the methods of access and other information will be located.
In additional to the Planned Maintenance Inspections related to those speci
fi
c Part Numbers below, Motorola
recommends that basic functional testing should be carried out every 24 months. These functional tests should
include RF Power Measurements, RF Frequency measurements, and Bit Error Rate measurements.
Motorola recommends regular site visits for other inspections, for example, site physical
security checks, generator maintenance, and so on.
Motorola also recommends that the antennae and PSU/Battery/UPS are also inspected and
functionally tested as advised by the respective manufacturers.
Note that the prime cabinet/expansion cabinet has ventilation holes and
is not suitable for environmentally unfriendly locations. Make sure the
ventilation holes and grilles are never covered.
It is recommended that periodic inspections of the heatsinks and interior of the MTS
are made. These will require cleaning occasionally due to the buildup of dust. The
frequency of this inspection is dependent upon the local environment and is more important
when the MTS is operating at a high ambient temperature.
Where used, the back-up battery charged by the MTS should be checked in
accordance with the manufacturer’s instructions.
