More Information - Cisco Catalyst Express 500 Getting Started Manual

• The dual-purpose uplink ports establish a link through
either the SFP module port or the 10/100/1000BASE-T
port, but not both at the same time. An SFP module port has
precedence over a 10/100/1000BASE-T port. If an SFP
module port has a link, that link is active. If the SFP port
does not have a link and the 10/100/1000BASE-T port does,
that link is active. Reselection occurs when the active link is
disconnected.
For a list of supported modules, see the Catalyst Express 500
Switch Release Notes on Cisco.com. For detailed instructions
on installing, removing, and connecting to SFP modules, see the
documentation that accompanied the module.
