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 part of this manual.
Ensure the power supply during software loading.
