Precautions
•
Make sure the fiber connector and fiber type match the transceiver module type.
•
The fiber ports on the switch are provided with dust plugs. Insert the dust plugs into the fiber
ports that you are not to use, to prevent particles from entering the ports.
•
Fiber connectors must be protected under safe and reliable outer packing, and be fitted with
dust caps. Fiber connectors must be installed with dust caps when they are not in use. Take
care not to scratch their end face. Replace the dust cap if it is loose or polluted.
•
Before connecting a fiber, use dust free paper and absolute alcohol to clean the end face of the
fiber connector. You can brush the end face only in one direction. You also need to brush the
end face of the fiber port.
•
Never bend or curve a fiber when connecting it. After a fiber is installed well, the bend radius
must be not less than 40 mm (the minimum dynamic bend radius is 20 D, and the minimum
static bend radius is 10 D. D indicates the outer diameter of dust caps).
•
If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted
surface (the filleting radius must be not less than 2 mm). When passing through a metallic board
hole or bending along the acute side of mechanical parts, the fiber must wear jackets or
cushions.
•
Insert and remove a plug with care. Never exert a fierce force to the fiber or plug; otherwise the
plug might be damaged or the fiber might be broken. Never pull, press or extrude the fiber
fiercely. For the allowed maximum tensile load and crush load, see
SFP+ copper cable
You can use SFP+ copper cables to connect the SFP+ ports. The SFP+ copper cables available for
the switch series are 10 G SFP+ Cu cables, as shown in
