Reattach the SC-type fiber-optic cable to the GBIC.
Step 5
Removing and Installing SFP Modules
Before you remove or install an SFP module, read the installation information in this section and the
"Laser Safety" section on page
Protect the SFP modules by inserting clean dust covers into them after the cables are removed. Be sure
Caution
to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another
SFP module. Avoid getting dust and other contaminants into the optical ports of your SFP modules,
because the optics will not work correctly when obstructed with dust.
Caution It is strongly recommended that you do not install or remove the 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 SFP module. Disconnect all cables before removing or installing an SFP module.
Removing and inserting an SFP module can shorten its useful life, so you should not remove and insert
SFP modules any more often than is absolutely necessary.
SFP modules use one of four different latching devices to install and remove the module from a port.
The four types of SFP module latching devices are described in the following sections:
