• You need to log in through the console port of the switch and perform the ONIE installation. • Other NOSes including user data will be removed when install PICOS under ONIE environment. • When the ONIE installer is used to downgrade the PICOS version from version 4.x to PICOS 3.x or lower versions, we first need to use ONIE to uninstall the higher version PICOS before proceeding with installing PICOS 3.x or a lower version. On the ARM platform, execute the onie_uninstaller command at the ONIE prompt to uninstall the current version PICOS. On the x86 platform, select the "ONIE: Uninstall OS" option in the GRUB menu to uninstall the current version PICOS. • If you enter GRUB rescue mode and the switch has GPT format partition, you can use the following commands to reset the GRUB boot variable to enter ONIE GRUB and then install PICOS. grub rescue> set prefix=(hd0,gpt2)/grub • Do not plug in the USB disk during onie-nos-installer process until ONIE starts up. If you have plugged in the USB disk before the installation operation, ONIE will find the installer on the USB disk when beginning the installation. On AS4610 series switches, when installation is complete, the installer will display: Please take out the usb disc, then remove the USB disk within 10 seconds after installation successful, and before machine restarts. • All X86 platforms share one installation and upgrade package with the name fixed as: onie-installer-picos-VERSION-x86.bin, where VERSION is the release version. X86 platform are listed below: • FS N5850-48S6Q • FS N8550-48B8C • FS N8550-32C • Edgecore AS4630-54PE • Edgecore AS5835-54X • DELL N3248P-ON • DELL S5212F-ON • DELL S5248F-ON • DELL Z9100-ON • DELL Z9264F-ON • DELL N3224T-ON• DELL S4128T-ON |
