Installing and Removing SFP Modules

Catalyst 2970 Switch Hardware Installation Guide
OL-6422-01
Use only Cisco SFP modules on the Catalyst 2970 switch. Each SFP 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 SFP module
meets the requirements for the switch.
For detailed instructions on installing, removing, and cabling the SFP module, see
your SFP module documentation.
Installing SFP Modules into SFP Module Slots

shows an SFP module that has a bale-clasp latch.
Caution
We strongly recommend that you do not install or remove fiber-optic SFP modules
with cables attached because of the potential damage to the cables, the cable
connector, or the optical interfaces in the SFP module. Disconnect all cables
before removing or installing an SFP module.
Removing and installing an SFP module can shorten its useful life. Do not remove
and insert SFP modules more often than is absolutely necessary.

module.
