TitleHow to perform netinstall on SLX 9540 using USB?
Perform netinstall on SLX 9540 to restore the firmware back to factory default.
  • SLX 9540
  • All codes
The netinstall process will re-partition and format the SLX SSD hard drive. So, all existing data (including licenses) on the SLX SSD hard drive will be erased!
  1. Create USB with EXT4 FS, format the USB to be 10GB to reduce formatting time
If a Linux system is not available to format the USB in EXT4, see article: How to format a USB drive with an EXT2 filesystem on Windows?
  1. Copy extracted firmware to the EXT4 formatted USB drive
  2. At the SLX host level (Ctrl-y+1), reboot the host, stop the boot, and get into the boot prom by entering "3"
Hit ESC to stop autoboot: 0
