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

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 troubleshooting 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 adoption 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.
