Note
Installing and Removing SFP Modules
These sections describe how to install and remove SFP modules. The modules are inserted into the
SFP module slots on the front of the Cisco ME switches. These field-replaceable modules provide uplink
interfaces.
You can use any combination of SFP modules. See the Cisco ME switch release notes for the list of
SFP modules that the Cisco ME switch supports. Each port must match the wave-length specifications
on the other end of the cable, and for reliable communications, the cable must not exceed the stipulated
cable length. See the
connections.
Use only Cisco SFP modules on the Cisco ME 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 the SFP module
documentation.

We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached
Caution
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.
