Warning
Installing SFP or SFP+ Modules
Each Cisco module has an internal serial electrically erasable programmable read-only memory (EEPROM)
that is encoded with security information. This encoding provides a way for Cisco to identify and validate
that the module meets the requirements for the switch.
For information about installing, removing, cabling, and troubleshooting SFP modules, see the module
documentation that is shipped along with your device.
Installing an SFP or SFP+ Module
Before you begin
When installing SFP or SFP+ modules, observe these guidelines:
• Do not remove the dust plugs from the modules or the rubber caps from the fiber-optic cable until you
are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination
and ambient light.
• To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the devices.
Removing and installing an SFP or SFP+ module can shorten its useful life. Do
not remove and insert any module more often than is necessary.
