Connecting to the Switch Ports
This section describes how to connect to the fixed switch ports and to the SFP module port. For
additional cabling information and a list of supported SFP modules, refer to the hardware installation
guide on Cisco.com.

Connect to 10/100 Ports and the 10/100/1000 Port

Follow these steps:

Connect to the 100BASE-FX Port

You can use either the 100BASE-FX port or the SFP module slot, but not both at the same time. By
default, the 100BASE-FX port is active if an SFP module is not installed in the switch at startup.
Follow these steps:
Step1 When you connect to servers,
workstations, IP phones, wireless
access points, and routers, insert a
straight-through, twisted four-pair,
Category 5 cable in a switch 10/100 or
10/100/1000 port. Use a crossover,
twisted four-pair, Category 5 cable
when you connect to other switches,
hubs, or repeaters.
Step2 Insert the other cable end into an RJ-45 connector on the other device.
Step1 Remove the dust plugs from the 100BASE-FX port and the rubber caps from the
MT-RJ patch cable. Store them for future use.
Step2 Insert an appropriate cable into the
100BASE-FX port. Insert the other
cable end into an SC port on the other
device.
