Connecting Destination Ports
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 B-35.
Figure B-35 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, t here might be a cable problem, or there might
be a 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 the target device.
Connecting to a Dual-Purpose Port
The dual-purpose port is a single port with two interfaces, one for an RJ-45 cable and another for an SFP
module. Only one interface can be active at a time. If both interfaces are connected, the SFP module has
priority. For more information about dual-purpose ports, see the “Dual-Purpose Ports” section on
page 1-5.
