Loading Software Through CLI 
By connecting a terminal to the switch, you can upgrade the Boot ROM program and load application 
files of the switch remotely through CLI.  
Loading Software Through USB Interface 
Each S5820X series switch provides a USB interface on its front panel. You can download the Boot 
ROM and application files to a removable storage device (such as a USB flash disk), and load the file 
through the USB interface.  
Suppose the Boot ROM and application files are stored in the file named update.bin, follow these steps 
to load the files from the USB flash disk.  
Step1 
Plug the USB flash disk containing the update.bin file in the USB interface of the switch.  
Step2 
Copy the update.bin file to the flash memory of the switch.  
<H3C> cd flash: 
<H3C> copy usba:/upadate.bin update.bin 
Step3 
Remove the USB flash disk, and then load the Boot ROM file.  
<H3C> bootrom update file update.bin slot 1 
  This command will update bootrom file on the specified board(s), Continue? [Y/ 
N]:y 
  Now updating bootrom, please wait... 
Step4 
Load the application file, and specify the file as the main program file.  
<H3C> boot-loader file update.bin slot 1 main 
  This command will set the boot file of the specified board. Continue? [Y/N]:y 
  The specified file will be used as the main boot file at the next reboot on slot 1!  
<H3C> display boot-loader 
Slot 1 
The current boot app is:  flash:/update.bin 
The main boot app is:     flash:/update.bin 
The backup boot app is:   flash:/update.bin 
<H3C> reboot

After loading the application file, use the reboot command to restart the switch to make the update 
take effect (make sure you have saved other configurations before restart).  
z
 
If the flash memory does not have enough space, you can load the Boot ROM file first, and then 
delete certain application files from the flash memory (you are recommended to delete the unused 
host program files); then, load the application file to the switch through FTP for update.

Avoid any power failure during the loading process.
