The port LED is amber while Spanning Tree Protocol (STP) discovers the
topology and searches for loops. This takes about 30 seconds, and then the port
LED turns green.
If the port LED does not come on, the device at the other end might not be turned
on, or there might be a cable problem or a problem with the adapter installed in
the attached device. See Chapter 3, “Troubleshooting,” for solutions to cabling
problems.
Step 4 Reconfigure and reboot the connected device if necessary.
Step 5 Repeat Steps 1 through 3 to connect to each 10/100 port.
Connecting to a 100BASE-FX Port
Warning
Invisible laser radiation may be emitted from the aperture ports of the
100BASE-FX single-mode supervisor engine module. Avoid exposure and do
not stare into open apertures.
Warning
Avoid exposure to the laser beam.
Caution Do not remove the rubber plugs from the fiber-optic port or the rubber caps
from the fiber-optic cable until you are ready to connect the cable. The plugs
and caps protect the fiber-optic port and cable from contamination and
ambient light.
You can connect the 100BASE-FX ports to other 100BASE-FX-compatible
network devices, such as servers, routers, and other switches. These ports use a
duplex SC connector, and you must provide the 50/125- or 62.5/125-micron
multimode fiber-optic cable to connect these ports to other 100BASE-FX devices.
The fiber-optic distances between the switch and the attached device follow.
