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 2000 Platform 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 replace-
ment.
In implementation of this policy, we have set up powerful card trouble-
shooting test resources in our factories and a rapid dispatch system oper-
ating 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.
