60. MAINTENANCE
60.1. Plug-in cards removal
9
Always switch off subracks power supply before removing or inserting any
active plug-in card.
60.2. Optical equipment
It is a good rule when working with the fibre optic components, to always have
available the appropriate screw covers for closure of the optic connectors that are
not connected. The intrinsic fragility of an optic connection must be highlighted. A
minimum layer of dust causes a notable increase of the insertion loss, therefore.
9
Always close the optic connectors that are not connected, with the appropriate
screw covers.
9
Always use compressed gas to remove any deposits in the receptacles before
closing them.
9
Use the appropriate cloths to clean the connectors.
9
Do not allow the male connector to come into contact with skin or oily
surfaces.

Should it be necessary to clean the optic connector, use pure alcohol only.
