ONIE installation instructions

This section describes the dierent methods to install ONIE on your switch.

NOTE: After installing the networking operating software (NOS) and diagnostics operating system (DIAG-OS), if you boot into

ONIE Install mode, ONIE assumes ownership of the system; ONIE Install mode is sticky. In this situation, ONIE stays in Install

mode until NOS and DIAG-OS are successfully installed again. If you want to boot into ONIE for any reason other than

installation, use Rescue mode or Update mode.

NOTE: To access ONIE, use the RJ-45 console port.

• Installing ONIE—these instructions use the universal serial bus (USB) method. To boot from a Linux USB, you must preinstall BIOS on

your system.

• ONIE operates using a 115200 baud rate. Ensure that any equipment attached to the serial port supports the required 115200 baud rate.

your system’s applicable values.

ONIE service discovery and OS installation

ONIE attempts to locate the installer through several discovery methods.

To download and run an installer, the ONIE Service Discovery feature follows these steps in order and uses the rst successful method

found:

1 Pass from the boot loader.

2 Search locally attached storage devices for one of the ONIE default installer lenames—for example, USB.

3 Discover the URLs from DHCPv4.

4 Report discovered URLs based on the DHCPv4 responses.

5 Query to the IPv6 link-local neighbors using HTTP for an installer.
