Modifying Startup Configuration Information

Context

When the system software on a device is damaged and you cannot log in to the device, you can use the BootLoad to upload the system software and patch file, and configure the device to start using the uploaded files. In this way, you can restore the system software and upgrade the device.

Before modifying startup configuration information, upload specified files to the flash memory using Enter ethernet submenu.

Procedure

In the startup configuration submenu, select 2 to enter the startup configuration submenu.

startup type(1: Flash)                                                          
  current: 1                                                                    
  new    :

Currently, the device supports only the flash memory. No setting is required.

Specify the system software.
```
Flash startup file (can not be cleared)                                         
  current: s5720hi.cc                                               
  new    :
```
Enter the name of the new system software and press Enter. If the current system software is available and does not need to be replaced, press Enter.
- When new system software is configured, the system checks the system software integrity. If the digital signature of the system software is invalid, the configuration fails. Therefore, ensure the system software validity.
- The specified system software must be available and exist in the flash memory; otherwise, the device fails to start. If the device fails to start three times using the specified system software, it starts with the system software used in the latest successful startup.
- If the system software to be specified is V200R008 or an earlier version, you must restore the default BootLoad password first according to Restoring the BootLoad Password and then specify the system software. Otherwise, the BootLoad password may not be used or a fault occurs on the switch. If the BootLoad password cannot be used after the downgrade, run the reset boot password command to restore the default BootLoad password again.
Specify the patch file.
```
patch package                                                                   
  current: s5720hi-sph005.pat                                         
  new    : 
```
Enter the name of the patch file and press Enter to return to the startup configuration submenu. Press Enter if you do not need to upgrade the patch file. The submenu for modifying the flash description is displayed. By default, no patch file is specified.
