Protect the SFP or SFP+ modules by inserting clean dust covers into them after the cables are removed.
Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of
another module. Avoid getting dust and other contaminants into the optical ports of your SFP or SFP+
modules, because the optics do not work correctly when obstructed with dust.
Caution
We strongly recommended that you do not install or remove the SFP or SFP+ module with fiber-optic
cables attached to it because of the potential to damage the cable, the cable connector, or the optical
interfaces in the module. Disconnect all cables before removing or installing an SFP or SFP+ module.
Removing and inserting an module can shorten its useful life, so you should not remove and insert modules
any more often than is absolutely necessary.
Caution
When installing an SFP or SFP+ module, you should hear a click as the triangular pin on the bottom of
the module snaps into the hole in the receptacle, indicating that the module is correctly seated and secured
in the receptacle. Verify that the modules are completely seated and secured in their assigned receptacles
on the line card by firmly pushing on each SFP or SFP+ module.
Note
