CAUTION
The connectors of the fiber-optic cables have to be mounted on their original plug-in
position. The fiber-optic cables and the plug sockets are labelled accordingly (U11, U21,
U31).
Carefully re-establish the plug connections and ensure that they are secure.
When dealing with connectors with a lock, make sure that the locking lever is securely
engaged once connected.
The screwed connections for the protective covers must only be tightened by hand.
