Connecting to an SFP Module
Note
Refer to the release notes for the latest information about SFP modules supported by the switch.
Follow these steps to connect a fiber-optic cable to an SFP module:
Step 1
Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
Step 2
Insert one end of the fiber-optic cable into the SFP module port, as shown in
Figure 2-8
Connecting to an SFP Module Port
Step 3
Insert the other cable end in 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.
