Dell EMC PowerSwitch S3048-ON Installation Guide March 2021

PDF

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
