Insert the other cable end in an RJ-45 connector on the target device.
Step 2
Step 3 Observe the port status LED.
The LED turns green when the switch and the target device have an established link.
The LED turns amber while Spanning Tree Protocol (STP) discovers the network topology and searches
for loops. This process takes about 30 seconds, and then the 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.
Step 4 Reconfigure and restart the target device if necessary.
Step 5 Repeat Steps 1 through 4 to connect each port.
