Maintenance procedure
Maintenance work on this instrument must only be undertaken by
qualified personnel using suitable equipment.
In most cases, it is advisable to contact the nearest Viavi Service Centre,
which will undertake the appropriate troubleshooting and repair work.
The performance and technical complexity of the SmartOTDR class this
instrument in a new generation of equipment, for which Viavi has laid
down a maintenance policy based on the principle of standard module
replacement.
In implementation of this policy, we have set up powerful card trouble-
shooting test resources in our factories and a rapid dispatch system
operating between our factories and branches.
Only by this procedure can the high quality of the instrument continue to
be ensured after repair work. This procedure also has the advantage of
reducing repair costs and time.
In the interests of quality and efficiency, we strongly recommend adop-
tion of the following procedure in the event of a fault, before any other
steps are taken:
– Verify that the instrument is plugged in.
– Check the connections of any peripheral equipment to the Platform.
– If a fault is detected, or in case of doubt, it is advisable to contact the
nearest Viavi Service Centre, which will undertake the appropriate
repair work.
