Software loading failure
Symptom
The device fails in software loading.
Solution
To resolve the issue:
1. Verify that the physical ports are connected securely and correctly. If a port is not connected securely, reconnect the port and make sure the connections are correct.

For example, check for the following errors that might occur:
¡ When you use XMODEM to load software, you select a baud rate other than 9600 bps, but you have not reset the baud rate for the HyperTerminal.
¡ When you use TFTP to load software, you entered an incorrect IP address, software name, or TFTP serve path.
¡ When you use FTP to load software, you entered an incorrect IP address, software name, username, or password.
3. If the issue persists, contact Technical Support.
