Before you install an OS
After powering on the S4112-ON Series (S4112F-ON and S4112T-ON) switch, it goes through a power-on self-test (POST).
POST runs every time the switch is initialized and checks the hardware components to determine if the switch is fully operational before
booting. After POST, the switch uses the Grub bootloader.
To select an entry, use the up and down arrow keys. Press Enter to select an operating software (OS) or enter e to edit the commands
before booting. Enter c for a command line. The selected entry runs automatically in the operating system.
Grub bootloader example
GNU GRUB version 2.02~beta2+e4a1fe391
