Connecting To A Dual-Purpose Port - Cisco IE 3000 Series Hardware Installation Manual

Connecting Destination Ports
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 a problem with the adapter installed in the target device. See
solutions to cabling problems.
If necessary, reconfigure and restart the switch or the target device.
Step 5

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
page
Class 1 laser product. Statement 1008
Warning
Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
Caution
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
the
information about the LC on the SFP module.
To connect to a dual-purpose port, follow these steps:
Connect an RJ-45 connector to the 10/100/1000 port, or install an SFP module into the SFP module slot,
Step 1
and connect a cable to the SFP module port. See
