Instructions

The ONIE Firmware Updater is a utility that runs within Open Network Install Environment (ONIE) to update firmware components on Dell open‑networking switches, such as the Dell PowerSwitch S5200‑ON series, Z series.
 

What does the ONIE Firmware Updater do?

The ONIE Firmware Updater checks versions and updates hardware firmware components, including:

  • BIOS
  • BMC (Baseboard Management Controller)
  • CPLD
  • FPGA
  • SSD firmware (when applicable)
  • ONIE

It ensures that all components are at Dell‑supported versions required for stable operation.

 

Note: The updater does not update PCIe firmware in S5200 platforms; PCIe updates must be performed using the DIAG OS.

 

How much time does it take to run ONIE Firmware Updater package?

The package includes multiple firmware components.

If a component on the switch already matches the version in the package, the upgrade for that component is skipped, saving time. 

If the package contains a newer version of a firmware component, it is upgraded.

The ONIE version is updated first, if needed, and the switch reboots to load the updated version and proceeds with the firmware upgrade (BIOS, CPLD, FPGA, and BMC). Once all the firmware is updated, the switch again reboots into the NOS (OS10, SONiC).

Typically, a full ONIE Firmware Update takes approximately 25+ minutes to complete. 

 

Where can we download the latest ONIE Firmware Updater package?

The ONIE Firmware Updater is available under the Drivers & Downloads section for your specific switch model.
