Connect Devices
When you connect devices to the switch ports,
refer to the Smartports role assignments that you
recorded in Step 10 of the Express setup
procedure.
Ethernet Connections
• Use either straight-through or crossover Category 5 cables with RJ-45 connectors to connect from
the switch Ethernet ports to other devices.
• By default, the PoE ports automatically provide up to 15.4 W power when IEEE
802.3af-compliant-powered devices are connected.
• By default, autonegotiation and auto-MDIX are enabled on the 10/100BASE-T and
10/100/1000BASE-T ports; the ports automatically provide the appropriate Ethernet connection.
Uplink port connections
• Use the 10/100/1000BASE-T port or add a Cisco fiber-optic SFP module to the SFP module port
for a Gigabit uplink connection to another switch. Use Category 5 cables with RJ-45 connectors
to connect to a 10/100/1000BASE-T port. Use LC fiber connectors to connect to a fiber-optic SFP
module.
• 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.
