Reference Guide

A replacement switch comes without an operation system or license installed. If you receive a replacement switch, you must
assign the STAG of the replacement switch to the SW entitlement in DDL and install the OS10 software and license.
Follow the steps for an ONIE switch without an OS installed to download OS10 Enterprise Edition and the license. See
Installation and Install OS10 license for complete installation and license information.
Installation using ONIE
If you purchase an open network install environment (ONIE)-only switch or if you want to replace an existing OS, you can install
an OS10 software image using ONIE-based auto-discovery or a manual installation:
● Automatic installation — ONIE discovers network information including the DHCP server, connects to an image server,
and downloads and installs an image automatically.
● Manual installation — Manually configure your network information if a DHCP server is not available, or if you install the
OS10 software image using USB media.
If OS10 is pre-installed on a switch, zero-touch deployment (ZTD) is enabled by default. ZTD automatically downloads and
installs an OS10 image in the standby partition. For more information, see Zero-touch deployment.
System setup
Verify that the system is connected correctly before installation:
● Connect a serial cable and terminal emulator to the console serial port — required serial port settings are 115200, 8 data bits,
and no parity.
● Connect the Management port to the network if you prefer downloading an image over a network. To locate the Console
port and the Management port, see the Getting Started Guide shipped with your device or the platform-specific Installation
Guide at www.dell.com/support.
Install OS10
If ONIE is installed on a device, navigate to the ONIE boot menu. An ONIE-enabled device boots up with pre-loaded diagnostics
and ONIE software.
+--------------------------------------------------------+
|*ONIE: Install OS |
| ONIE: Rescue |
| ONIE: Uninstall OS |
| ONIE: Update ONIE |
| ONIE: Embed ONIE |
| ONIE: Diag ONIE |
+--------------------------------------------------------+
● Install OS — Boots to the ONIE prompt and installs an OS10 image using the automatic discovery process. When ONIE
installs a new operating system (OS) image, the previously installed image and OS10 configuration are deleted.
● Rescue — Boots to the ONIE prompt and allows for manual installation of an OS10 image or updating ONIE.
● Uninstall OS — Deletes the contents of all disk partitions, including the OS10 configuration, except ONIE and diagnostics.
● Update ONIE — Installs a new ONIE version.
● Embed ONIE — Formats an empty disk and installs ONIE.
● Diag ONIE — Runs the system diagnostics.
After the ONIE process installs an OS10 image and you later reboot the switch in ONIE: Install OS mode (default), ONIE
takes ownership of the system and remains in Install mode (ONIE Install mode is sticky) until an OS10 image successfully installs
again. To boot the switch from ONIE for any reason other than installation, select the ONIE: Rescue or ONIE: Update
ONIE option from the ONIE boot menu.
CAUTION:
During an automatic or manual OS10 installation, if an error condition occurs that results in an
unsuccessful installation, perform Uninstall OS first to clear the partitions if there is an existing OS on the
device. If the problem persists, contact Dell EMC Technical Support.
Automatic installation
You can automatically install an OS10 image on a Dell ONIE-enabled device. Once the device successfully boots to ONIE: Install
OS, auto-discovery obtains the hostname, domain name, Management interface IP address, as well as the IP address of the DNS
name server(s) on your network from the DHCP server and DHCP options. The ONIE automatic-discovery process locates the
stored software image, starts installation, then reboots the device with the new software image.
