Chapter 3: Troubleshooting
This chapter describes how to isolate and solve common problems during the installation of the SG200.
A Network Link is Not Established
At the back of the appliance, each of the two network connections has two LEDs—the LED on the right
flashes amber to indicate network activity and the LED on the left glows green to indicate a functional
network connection.
Figure 3-1: Verify the Network Link
If the LED on the left is not green for either connection, a network link is not established. Check the
following:
•
Verify that each cable is connected properly, such as to a switch or a hub. If you are connecting your
SG200 to your PC (see
“Connecting the SG200 to a PC”
on page 12), verify that the crossover cable is
connected between the PC and the SG200, and not between the SG200 and the LAN.
•
Try using a different network cable.
These LEDs
should be green
