Before you install an OS
After powering on the S3048-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 which entry is highlighted, use the up and down arrow keys. 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
