Upgrading ONIE on the S4048-ON
To upgrade the ONIE package you have installed, use one of the following two processes: zero touch (dynamic) update or
manual update.
1. Zero touch (dynamic): Copy the updated ONIE installer and the DIAG installer for your system to the TFTP/HTTP
server. Configure the DHCP options using the ONIE specifications shown at the following link: https://github.com/
opencomputeproject/onie/wiki/Design-Spec-SW-Image-Discovery.
S4048-ON image >>>> onie-updater-x86_64-dell_s4000_c2338-r0.3.21.1.0-5
2. Manual: Copy the image onto the TFTP/HTTP servers and boot ONIE. Update the ONIE using the onie-self-update
command, then download and run an ONIE updater image.The supported URL types are: HTTP, FTP, TFTP, and FILE.
