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 6000A V2 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 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 6000A V2
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.
Changing the
module carrier
If the module carrier installed onto the Platform must be changed,
proceed as follows:
1 Switch off the Platform and disconnect the mains supply.
2 Turn the instrument face down on the work surface.
3 Unscrew the 4 screws on the 4 extremities of the pack module
installed onto the Platform.
4 Pull the pack gently to remove it from the Platform.
5 Set the new module carrier, making flush the connectors (2a & 2b)
on both parts and the 4 screws with the 4 holes provided for those
screws (1a -> 1d).
