7. During the compute node POST cycle, press F11 to open the Boot Manager. You may need to press F11
multiple times in quick succession. You can perform this operation by connecting a video/keyboard or by
using the console in BMC.
8. Select One Shot > USB Flash Drive from the menu that appears. If the USB thumb drive does not appear
in the menu, verify that USB Flash Drive is part of the legacy boot order in the BIOS of the system.
9. Press Enter to boot the system from the USB thumb drive. The firmware flash process begins.
After firmware flashing is complete and the node reboots, it might take a few minutes for ESXi to start.
10. After the reboot is complete, exit maintenance mode on the upgraded compute node using vCenter.
11. Remove the USB flash drive from the upgraded compute node.
12. Repeat this task for other compute nodes in your ESXi cluster until all compute nodes are upgraded.
Use the Baseboard Management Controller (BMC) user interface (UI)
You must perform the sequential steps to load the compute node firmware ISO and reboot the node to the ISO
to ensure that the upgrade is successful. The ISO should be located on the system or virtual machine (VM)
hosting the web browser. Ensure that you have downloaded the ISO before you start the process.

The recommendation is to have the system or VM and the node on the same network.

It takes approximately 25 to 30 minutes for the upgrade via the BMC UI.
• Upgrade firmware on H410C and H300E/H500E/H700E nodes
• Upgrade firmware on H610C/H615C nodes
Upgrade firmware on H410C and H300E/H500E/H700E nodes
If your node is part of a cluster, you must place the node in maintenance mode before the upgrade, and take it
out of maintenance mode after the upgrade.

Ignore the following informational message you see during the process:
Firmware Key is used, SecureFlash is currently in Debug Mode
Steps
1. If your node is part of a cluster, place it in maintenance mode as follows. If not, skip to step 2.
a. Log in to the VMware vCenter web client.
b. Right-click the host (compute node) name and select Maintenance Mode > Enter Maintenance
Mode.
c. Click OK.
VMs on the host will be migrated to another available host. VM migration can take time depending on
the number of VMs that need to be migrated.

2. Navigate to the BMC UI, https://BMCIP/#login, where BMCIP is the IP address of the BMC.
3. Log in using your credentials.
Ensure that all the VMs on the host are migrated before you proceed.
