Maintenance and troubleshooting
7.1
Loading failure handling
After the loading fails, the system will maintain running on the original version. At this moment,
users should recheck whether the physical ports are connected properly first. Where any port hasn’t
been connected properly, connect the port again, ensure correct physical connection, and restart the
loading procedures. Where the physical connection is proper, check the information on the loading
procedures shown on the HyperTerminal, and check whether there exist input errors, etc. Where
there exist input errors, please correct input errors and reload. For example, having entered wrong IP
addresses of Server and Switch when using TFTP protocol, wrong name of loading software, and
failing to designate correct working path of correct TFTP server, etc.; where the loading finally fails
in case of proper physical connection and no input error during the loading, please contact your
technical support/seller/agent for help.
