Before you install an OS
After powering on the S4048-ON switch, it goes through a power-on self-test (POST).
POST runs every time that the switch is initialized and checks hardware components to determine if the switch is fully
operational before booting. After POST, the switch uses the Grub bootloader.
Use the up and down arrow keys to select which entry is highlighted. Press Enter to select an OS or enter e to edit the
commands before booting. Enter c for a command line. The highlighted entry runs automatically in the operating system.
Example of the grub bootloader
GNU GRUB version 2.02~beta2+e4a1fe391
