Step 2
Connect the other end of the cable to an RJ-45 connector on the other device. The
port LED comes on when both the switch and the connected device have
established link.
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 3 Reconfigure and reboot the connected device if necessary.
Step 4 Repeat Steps 1 through 3 to connect each device.
