The sections below describe some of the different ways you can install the Cumulus Linux image, such as using a DHCP/web server, TFTP, FTP, a local file, or a USB drive.

Cumulus Linux is already installed on the switch but you want to use ONIE to reinstall Cumulus Linux or upgrade to a newer version.

No image is installed on the switch (the switch is only running ONIE).

You can install a new Cumulus Linux image using ONIE, an open source project (equivalent to PXE on servers) that enables the installation of network operating systems (NOS) on bare metal switches.īefore you install Cumulus Linux, the switch can be in two different states: Cumulus Linux provides command line options to change the default password automatically during the installation process. Be sure to update any automation scripts before installing a new image. The first time you log into Cumulus Linux, you are required to change this default password. In Cumulus Linux 4.2.0, the default password for the cumulus user account has changed to cumulus.
