Install firmware upgrade
You may need to upgrade the firmware components on an OS10 switch without upgrading the OS10 image.
NOTE: Do not upgrade the ONIE firmware and OS10 image simultaneously. Perform the ONIE firmware upgrade first before
you upgrade the OS10 image.
To upgrade firmware components in a separate operation:
1. Download the OS10 firmware file from a server using the image download server-filepath/firmware-filename
command in EXEC mode; for example:
OS10# image download http://10.11.8.184/tftpboot/users/regr//neteng/okelani/files
/new/onie-firmware-x86_64-dellemc_s5200_c3538-r0.3.40.5.1-9.bin
2. Install the OS10 firmware file using the image install firmware-file-url command in EXEC mode, where
firmware-file is the name of the firmware file downloaded in Step 1; for example:
OS10# image install image://onie-firmware-x86_64-dellemc_s5200_c3538-r0.3.40.5.1-9.bin
To view the pending firmware upgrade, use the show image firmware command. To cancel a firmware installation and
remove any pending firmware upgrades, use the image cancel command.
3. Reload the switch in EXEC mode.
OS10# reload
Upgrade OS10 automatically using ZTD
The ZTD process is enabled by default and starts an automatic discovery process, similar to the ONIE discovery process.
ZTD starts the Dynamic Host Configuration Protocol (DHCP) client on all the interfaces, including management and front-panel
ports. ZTD sends DHCP discovery packets with DHCP option 60 (vendor-class specifier) on all the interfaces and listens for the
DHCP offer. The DHCP server responds with Option 240 in its response (the DHCP offer). Option 240 includes the valid OS10
image and configuration files. The system proceeds with ZTD, installs OS10 image, and executes the configuration files.
NOTE: The DHCP server response with Option 240 can be received through the management port or a front-panel port.
The ZTD auto discovery runs continuously until any of the discovery methods complete or you cancel the ZTD process manually
using the ztd cancel command or you enter into the CONFIGURATION mode.

After ZTD completes, use the show ztd-status command to view the ZTD status. A message similar to the following one
appears:
OS10# show ztd-status
-----------------------------------
ZTD Status : disabled
ZTD State : completed
Protocol State : idle
Reason : ZTD process completed successfully at Sun Nov 7 09:42:52 2021
