these sections describe how to install and remove sfp modules. the modules are inserted into the sfp module slots on the front of the catalyst 3560 switches. these field-replaceable modules provide uplink interfaces.

    you can use any combination of sfp modules. see the catalyst 3560 release notes for the list of sfp modules that the catalyst 3560 switches support. 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 “installation guidelines” section on page 2-4 for cable stipulations for sfp connections.

    use only cisco sfp modules on the catalyst 3560 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.
