Procedure:
1
Switch the controller off and disconnect the power supply cable before
partially pulling out the optical ports panel
.
2
Loosen the four screws of the optical ports panel, so that these protrude at
least 1 cm (see figure 13).
3
Partially pull out the optical ports panel holding the optical ports from the
housing. Stop pulling when the module is located in the position as shown in
figure 13 and you feel resistance against pulling it out further.
4
Press on the locking tab of the connector that you wish to clean and carefully
pull it out completely from the corresponding mating adapter.
5
Carefully pull out the orange glass fibre cable a few centimetres from the
housing, but under no circumstances beyond the point of resistance, until the
connector reaches the position as shown in figure 13
.
6
Now you can perform, as described above, a visual inspection of the
connector and clean it with a cloth
.
7
Then carefully push the cleaned connector with the glass fibre cable back into
the housing without kinking or crushing the glass fibre cable
.
8
Carefully plug the connector into the corresponding mating adapter and
engage it by means of the locking tab. Ensure that the channel number
indicated on the glass fibre cable matches the channel number assigned to
the mating adapter on the optical ports panel.
9
Carefully push the optical ports panel holding the optical ports back into the
housing without kinking the glass fibre cable(s).
10 Tighten the four screws.
CAUTION!
The printed circuit board, on which the mating adapters are mounted, holds
sensitive electronic components. Do not touch them!
The manipulation of other components, which are accessible when the optical
ports panel is partially pulled out, will void the warranty and liability of the
manufacturer.
Do not disconnect the electrical connection to the printed circuit board!
