  • Secure boot and common BIOS support (QFX5241-64OD and QFX5241-64QD)—The secure boot implementation is based on the UEFI 2.4 standard. The BIOS has been hardened and serves as a core root of trust. The BIOS updates, the bootloader, and the kernel are cryptographically protected. Secure boot is enabled by default on supported platforms.
