— 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
problems.
4. If necessary, reconfigure and restart the switch or 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
Warning: Class 1 laser product. Statement 1008
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.
Caution: Before connecting to the SFP module, be sure that you understand the port and cabling stipulations in the
Preparing for Installation, page
To connect to a dual-purpose port, follow these steps:
1. Connect an RJ-45 connector to the 10/100/1000 port, or install an SFP module into the SFP module slot, and
connect a cable to the SFP module port. See
