Before you install an OS

After powering on the S4048-ON system, it goes through a power-on self-test (POST).
POST runs every time the switch is initialized and checks hardware components to determine if the switch is fully operational before
booting. After POST, the system 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 executes automatically in the operating system.
Example of the grub bootloader
GNU GRUB version 2.02~beta2+e4a1fe391
