Switch Installation
Installing SFP and SFP+ Modules
Some switch models support SFP modules, SFP+ modules, or both. The SFP slots support only the SFP
modules. The SFP+ slots support both SFP and 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.
