Connectivity Guide

For an ONIE-enabled switch, navigate to the ONIE boot menu. An ONIE-enabled switch boots up with pre-loaded diagnostics (DIAGs) 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
OS image, the previously installed image and OS10 conguration are deleted.
• Rescue — Boots to the ONIE prompt and allows manual installation of an OS10 image or ONIE update.
• Uninstall OS — Deletes the contents of all disk partitions, including the OS10 conguration, except ONIE and diagnostics.
• Update ONIE — Installs a new ONIE version.
• Embed ONIE — Formats an empty disk and installs ONIE.
• EDA DIAG — 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 and if there is an existing OS on the device, select Uninstall OS to clear the partitions. If the problem persists,
contact Dell EMC Technical Support.
Automatic installation
You can automatically install, also known as zero-touch install, an OS10 image on a Dell EMC ONIE-enabled device. After the device
successfully boots to ONIE: Install OS, auto-discovery obtains the hostname, domain name, Management interface IP address, and the IP
address of the domain name server (DNS) 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.
If you insert USB device, auto-discovery searches the USB storage supporting FAT or EXT2 le systems. It also searches SCP, FTP, or
TFTP servers with the default DNS of the ONIE server. DHCP options are not used to provide the server IP. Auto discovery repeats until a
successful software image installation occurs and reboots the switch.
Example for automatic installation
1 Use the mv image_name onie-installer command to rename the image as onie-installer.
mv PKGS_OS10-Base-10.3.1B.144-installer-x86_64.bin onie-installer
2 After renaming, the system enters the ONIE: Install mode. Enter the command onie-discovery-start, which
automatically discovers the onie-installer image from the DHCP server.
ONIE:/ # onie-discovery-start
discover: installer mode detected. Running installer.
Starting: discover... done.
ONIE:/ # Info: eth0: Checking link... up.
Info: Trying DHCPv4 on interface: eth0
ONIE: Using DHCPv4 addr: eth0: 10.10.10.17 / 255.0.0.0
Info: eth1: Checking link... down.
ONIE: eth1: link down. Skipping configuration.
ONIE: Failed to configure eth1 interface
