After a codec is upgraded using the upgrade tool, "Failed" is displayed on the upgrade tool, and the codec cannot restart.
Use the bootrom system to implement the upgrade.
Before the upgrade, power off the codec. Set switch 1 to ON and retain the current settings for switch 2. Power on the codec. The default codec IP address is 192.168.1.1. Then upgrade the normal system.
Step 1 Run the Ping command to check the network communication between the computer used for the upgrade and the codec, as shown in the Figure 5-5.
If the computer fails to communicate with the codec, ensure that the IP addresses of the computer and codec are in the same network segment.
