Overview
The Open Network Install Environment (ONIE) is a small Linux-based operating
system that provides an open install environment for network switches without
operating systems.
ONIE enables a network switch ecosystem where end-users can choose among
different Network Operating Systems (NOS). Practically, ONIE boots on a switch,
discovers NOS installer images available on the local network or on a USB drive,
copies the chosen image to the switch, and provides an environment where the
installer can load the NOS onto the switch.
ONIE is classified as free software, meaning it can be redistributed and/or modified
under the terms of version 2 of the GNU General Public License as published by the
Free Software Foundation. To read the license, visit the following link:

12 Lenovo ONIE Quick Start Guide for NE1032T
Installing the ONIE FoD License Key
ONIE is not installed by default and it can be activated only using a Feature on
Demand (FoD) license key. The process of obtaining and installing a FoD license key
is described in the following pages.
Obtaining the ONIE License Key
The ONIE license key or activation key can be acquired using the Lenovo Features on
Demand (FoD) website:
http://fod.lenovo.com/lkms/
You can also use the website to review and manage the license, and to obtain
additional help if required.
Note: An ID and password are required to log into the FoD website. If you do not
have an ID, you can register at the website.
The ONIE FoD license key is provided as a file that must be downloaded to the
switch. To obtain an activation key, acquire an Authorization Code from the Lenovo
Features on Demand website.
To acquire the Authorization Code, you need to provide the unique ID (UID) of the
specific switch where the ONIE license key is to be installed. The UID is the last 12
characters of the switch serial number. This serial number is located on the Part
Number (PN) label.
You can also view the UID of a switch using the following command:
Lenovo Cloud Network OS:
Once the ONIE license key file is acquired from the Lenovo Features on Demand
website, it must be installed on the NE1032T.

16 Lenovo ONIE Quick Start Guide for NE1032T
Booting in ONIE Mode
After you activate and install an ONIE image, you can boot the switch in ONIE
mode. ONIE offers four modes for booting, each providing a different operation:
ONIE install mode
ONIE rescue mode
ONIE uninstall mode
ONIE update mode
There are two ways to boot the switch in an ONIE mode:
using the Command Line Interface (CLI):
Lenovo Cloud Network OS:
–startup image onie-image install
–startup image onie-image rescue
–startup image onie-image uninstall
–startup image onie-image update
using the Boot Management Menu (for more details, see “The Boot Management
Menu” on page 19)
Note: For CNOS, the CLI commands for booting in different ONIE modes display
an error if the ONIE license key is not installed on the switch. To install the ONIE
license key, see “Installing the ONIE FoD License Key” on page 12.
The following pages describe the four ONIE modes and how the CLI commands
can be used to boot the switch in each mode.
Booting in ONIE Install Mode
This mode is used to install a NOS using ONIE. The ONIE install mode boots the
ONIE kernel and file-system and executes the ONIE discovery process. The
discovery process uses a number of different mechanisms to find a NOS installer
program.
Once a NOS installer is found, it is downloaded and executed. The installer loads
the Network OS on the switch, updates required ONIE environment variables, and
reboots the switch.
The switch now runs its newly installed Network OS and behaves like a regular
switch. The user can, at any point, reboot and run the ONIE installer again to
install another Network OS.
The Lenovo ONIE installer image, which installs the different Lenovo Network
Operating Systems, is called
onie-installer-powerpc-lenovo_ne1032t-r0 ,
and it is available at the following link:
http://support.lenovo.com/

To boot the switch in ONIE install mode on the next reload, use the following
command from the switch CLI:
Lenovo Cloud Network OS:
To check which in ONIE mode the switch is configured to boot, use the following
command
from the switch CLI :
Lenovo Cloud Network OS:
Booting in ONIE Uninstall Mode
This mode is used to uninstall a NOS using ONIE. The ONIE uninstall mode boots
the ONIE kernel and deletes the NOS image running on the switch. After the
uninstall is complete, the ONIE discovery process is executed.
To boot the switch in ONIE uninstall mode on the next reload, use the following
command from the switch CLI:
Lenovo Cloud Network OS:
Note: The following warning is displayed after choosing ONIE uninstall mode.
You are prompted for confirmation:
Once you confirm, the switch boots in ONIE uninstall mode on the next reload. For
more details, see “Uninstalling the Lenovo Network OS” on page 20.
NE1032T(config)# startup image onie-image install
NE1032T# display boot
Current ZTP State: Enable
Current FLASH software:
active image: version 10.4.2.0
standby image: version 0.0.0.0
Uboot: version 10.4.2.0
ONIE: version 10.4.2.0
Currently set to boot ONIE install mode
Currently scheduled reboot time: none
Current port mode: default mode
NE1032T(config)# startup image onie-image uninstall
WARNING: Booting ONIE in uninstall mode will completely uninstall the
operating system!
Only the ONIE image will be preserved.
Are you sure you want the next boot to uninstall the OS? (y/n)

18 Lenovo ONIE Quick Start Guide for NE1032T
Booting in ONIE Update Mode
ONIE update mode installs a new version of ONIE on the switch, including the
boot loader and the Linux kernel. It works similarly to the ONIE install mode,
except the discovery process searches for an ONIE image instead, and not a NOS
image.
Notes:
This only upgrades the ONIE partition on the switch and does not affect the
NOS image.
The ONIE updater image is called
onie-updater-powerpc-lenovo_ne1032t-r0.
This also installs a different version of the ONIE boot loader, which does not
support running Lenovo Network OS. If you wish to boot Lenovo NOS, you
have to re-install it by using ONIE Install mode (for more details, see “Booting in
ONIE Install Mode” on page 16).
To boot the switch in ONIE update mode on the next reload, use the following
command from the switch CLI:
Lenovo Cloud Network OS:
Note: Upon reloading after the update process is completed, the switch is not able
to load the Lenovo Network OS, booting into ONIE Install mode instead. To access
the console port at this point, you must change the default baud rate of the
terminal emulator to 115,200 bps.
Booting in ONIE Rescue Mode
ONIE rescue mode is useful when trying to recover from a broken NOS image. It
works similarly to the ONIE install mode, except the ONIE discovery process is
disabled. ONIE will not try to find and install a NOS image. This allows for the
troubleshooting of the system.
To boot the switch in ONIE rescue mode on the next reload, use the following
command from the switch CLI:
Lenovo Cloud Network OS:
NE1032T(config)# startup image onie-image update
NE1032T(config)# startup image onie-image rescue

switch to boot in different ONIE modes.
You can interrupt the startup process of the switch and enter the Boot Management
menu from the serial console port. When the system displays the following
message, press Shift + B. The Boot Management menu appears.
Note: For CNOS, the submenu is available, but executing any of its options results
in an error, unless the ONIE license key is installed. For more details, see
“Installing the ONIE FoD License Key” on page 12.
To enter the ONIE submenu, press O .
The ONIE submenu allows you to perform the following actions:
