DGX H100/H200 System Firmware Update Guide Version 25.12.2#

Highlights#

Added Support#

  • Enabled NVMe and Trusted Platform Module (TPM) out-of-band firmware update.

BMC Fixes#

  • Updated OpenSSH to version openssh-10.0p1-2.

  • Incorporated security fixes in bootloader to address squashfs vulnerabilities.

  • Resolved an issue where fans were running at maximum speed.

  • Resolved an issue where differing time zone settings between the BMC and HMC caused continuous communication recovery attempts.

  • Enhanced BMC stability.

SBIOS Fixes#

  • No SBIOS fixes for this release.

The nvfwupd Command Updates#

  • An activation command (RF_PWR_STATUS) has been introduced to provide reliable insight into system power, making firmware updates, maintenance, and monitoring much safer and more efficient.

  • Introduced flint support for updating firmware directly on the host system.

  • A delay mechanism (Update_Delay feature) has been introduced to avoid memory overload and keep simultaneous BMC/HMC updates running smoothly.

  • Support added for OEM parameter support for firmware updates using the --oem_parameters option.

  • Tarfile support for PowerShelf update packages has been restored.
