Installing SFP Modules
See the switch release notes on Cisco.com for the list of supported SFP modules. Use only Cisco SFP modules
on the switch. Each Cisco module has an internal serial 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 shipped with your device.
Installing an SFP Module
Before you begin
When installing 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 switch and other devices.
Removing and installing an SFP module can shorten its useful life. Do not remove
and insert any module more often than is absolutely necessary.
