Connecting to SFP and SFP+ Modules
Figure 2-24 Connecting to a Fiber-Optic SFP Module Port
Step 3 Insert the other cable end into a fiber-optic receptacle on a target device.
Step 4 Observe the port status LED.
The LED turns green when the switch and the target device have an established link.
The LED turns amber while the STP discovers the network topology and searches for loops. This process
takes about 30 seconds, and then the port LED turns green.
If the LED is off, the target device might not be turned on, there might be a cable problem, or there might
be problem with the adapter installed in the target device. See
Chapter 3, “Troubleshooting,” for
solutions to cabling problems.
Step 5 If necessary, reconfigure and restart the switch or target device.
Connecting to 1000BASE-T SFP
Caution To prevent ESD damage, follow your normal board and component handling procedures.
Step 1 Connect one end of the cable to the SFP module port (see Figure 2-25). When connecting to servers,
workstations, and routers, use a four twisted-pair, straight-through cable. When connecting to switches
or repeaters, use a four twisted-pair, crossover cable.
When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.
Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by
default. For configuration information for this feature, see the switch software configuration
guide or the switch command reference on Cisco.com.
