Connecting to a Fiber-Optic SFP Module
Follow these steps to connect a fiber-optic cable to an SFP module:
Caution Do not remove the rubber plugs from the SFP module port or the rubber caps from
the fiber-optic cable until you are ready to connect the cable. The plugs and caps
protect the SFP module ports and cables from contamination and ambient light.
Before connecting to the SFP module, be sure that you understand the port and
cabling stipulations in “Installation Guidelines” section on page 3-7 and in the
“SFP Module Slots” section on page 2-12. See Appendix B, “Connector and
Cable Specifications” for information about the LC on the 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 (see Figure 3-46).
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 4, “Troubleshooting,” for solutions to cabling problems.
