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.

Procedure

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.

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.
