Maintenance and Troubleshooting
7.1 Troubleshooting of Load Failure
In the case of load failure, the system will run the original version. In this case, users ought to check
connection of physical ports first. If port connection is not made properly, reconnect the ports
correctly, and conduct reloading. If physical connection has no problem, check the loading process
information displayed on the hyper terminal for input error. If input error exists, correct the input
error, and conduct reloading. For example, inputting wrong IP addresses of Server or Switch or
wrong loader software name, or failure to designate correct operating path of correct TFTP server
when using TFTP protocol. If you fail to load without physical connection error and input error,
please contact your technical support/salesperson/agent for help.

Bootrom> run bootcmd
CAUTION
By using the above commands, the system will clear the file startup-config; the startup-config
