Step 3: Restart the switch.
<4210> reboot
n
Before restarting the switch, make sure you have saved all other configurations
that you want, so as to avoid losing configuration information.
2 Loading host software
Loading the host software is the same as loading the Boot ROM program, except
that the file to be downloaded is the host software file, and that you need to use
the boot boot-loader command to select the host software used for next startup
of the switch.
After the above operations, the Boot ROM and host software loading is
completed.
Pay attention to the following:
The loading of Boot ROM and host software takes effect only after you restart
■
the switch with the reboot command.
If the space of the Flash memory is not enough, you can delete the unused files
■
in the Flash memory before software downloading. For information about
deleting files, refer to "File System Management Configuration" on page 423.
Ensure that the power supply is available during software loading.

Loading Procedure Using FTP Server

to the switch.
