Connectivity Guide

• Automatic installation — ONIE discovers network information including the Dynamic Host Conguration Protocol (DHCP) server,
connects to an image server, and downloads and installs an image automatically.
• Manual installation — Manually congure 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
Before installation, verify that the system is connected correctly:
• Connect a serial cable and terminal emulator to the console serial port — serial port settings are 115200, 8 data bits, and no parity.
• Connect the Management port to the network to download an image over a network. To locate the Console port and the Management
port, see the platform-specic Installation Guide at www.dell.com/support.
Install OS10
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: 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.
