After the telepresence host is upgraded using the upgrade tool, "Failed" is displayed on the upgrade tool, and the telepresence host cannot restart.
Before performing the following steps, set DIP switch 3 to ON and power on the telepresence host.
Step 1 Run the Ping command to check the network communication between the computer used for the upgrade and the telepresence host, as shown in the Figure 5-1.
If the computer fails to communicate with the telepresence host, ensure that the IP addresses of the computer and telepresence host are in the 192.168.1.X network segment.
