Equipment Precautions
The following information is given to prevent equipment damage.
When connecting optical patch cables to the SCUs, always follow ESD preven-
tion practices:
•
Ensure that the FSP 3000R7 shelves and the
ROADM-C40/40/OPM-3HU/2DC are electrically connected to earth through
the protective earthing conductor provided for installation.
•
Wear an ESD-preventive wrist strap, making sure that it makes good skin
contact.
•
Fasten the earthing cable of the wrist strap onto the ESD grounding point on
the shelf (if available) or to a bare metal surface onto the rack.
Optical patch cables subject to breakage, if mishandled. Handle cables with
extreme care.
Interconnecting Shelves
This section provides all relevant information about the concepts of the
shelf-to-shelf communications and gives detailed procedures for interconnect-
ing the Shelf Control Units.
This section includes the following subsections:
Interconnecting 7HU Shelves and 1HU Shelves using SCU Modules
Interconnecting 1HU Shelves with SCU-S Modules
Risk of damage due to electrostatic discharge!
Each FSP 3000R7 shelf contains modules which are sensitive to
electro-static discharge (ESD). To avoid possible ESD damages to
sensitive circuit boards, implement and maintain adequate measures
of ESD damage prevention when interconnecting shelves!
NOTICE
(1)The SFP transceiver cages of the SCU modules will be
equipped with dust plugs on delivery to prevent
impurities. These dust plugs should be in the cages as
long as the modules are not installed in a running system.
(2)Unused pluggable interfaces intended for connecting
extension shelves need not be equipped with
transceivers but must be covered with dust plugs.
