Installing and Removing Transceiver Modules

Installing and Removing SFP Modules
Before you remove or install an SFP or SFP+ module, read the installation information in this section.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments. Statement 1051
Caution 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.
Figure 22: SFP/SFP+ Module Cage Cover
Protect the SFP or SFP+ modules by inserting clean dust covers into them after the cables are removed.
Caution
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.
