Hope this helps...

AND/OR

Installing OS9 on Dell S4048T-ON via USB or Disk Image

1. Prepare the OS9 Image

  • Download the correct OS9 firmware for S4048T-ON from Dell’s support site.

2. Boot into ONIE (Open Network Install Environment)

  • Power on the switch and, at the GRUB menu, select ONIE.

3. Install OS9 Using USB Drive

  • Format a USB drive with FAT32.

  • Copy the OS9 .bin installer to the USB.

  • Insert the USB into the switch.

  • In ONIE, use the ONIE install command to point to the USB file, e.g.

    text
onie-nos-install /dev/sdb1/<os9-filename>.bin

(Replace /dev/sdb1 with your USB device path and <os9-filename> with the actual file name.)

4. Alternative: Install via Network

  • You can also use TFTP/FTP to install OS9, e.g.:

text
onie-nos-install tftp://<server-ip>/<os9-filename>.bin

or use FTP as shown in this video guide

  • .

5. Using dd to Write Image Directly (Advanced)

  • If you have a full disk image (.img), you can remove the SSD, connect it to another system, and use dd:

  • text
    dd if=<os9-image>.img of=/dev/sdX bs=4M

    (Replace /dev/sdX with your SSD device.) Reinstall the SSD and boot.

6. First Boot

  • After installation, the switch will reboot into OS9. Complete initial setup via console.

Tip: If ONIE is missing or corrupted, use Dell’s recovery ISO to restore ONIE first
