Chapter 2 Switch Installation
Note
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
Step 2
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

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
problems.
Reconfigure and reboot the connected device if necessary.
