Cisco Catalyst 2960-L User Manual

Do not remove the rubber plugs from the SFP or 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.
Caution
SUMMARY STEPS
1. Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
2. Insert one end of the fiber-optic cable into the SFP or SFP+ module port.
3. Insert the other cable end into a fiber-optic receptacle on a target device.
4. Observe the port status LED.
DETAILED STEPS
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 or 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.
