Install and Remove SFP Modules
Before you remove or install an SFP or SFP+ module, read the installation information in this section.
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or
view directly with optical instruments. Statement 1051
Warning
Protect the line card by inserting a clean SFP/SFP+ module cage cover, shown in the figure below, into the
optical module cage when there is no SFP or SFP+ module installed.
Caution
Figure 12: SFP/SFP+ Module Cage Cover
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 by 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 of damaging 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 a module can shorten its useful life, so you should not remove and insert modules any more than is
absolutely necessary.
