Protected access to the BIOS and the bootloader

The BIOS of the Management Unit, HNC and Server Unit x86 is protected by a password which is known to Customer Support.

The bootloader GRUB (GRand Unified Bootloader) which is used by Linux is also protected by a password which is known by Customer Support.

By default the rack console (local console) is attached to the Management Unit. When you switch over the console switch (see section "Access via the local console"), you can reach BIOS and GRUB from the HNC or SU x86 via the local console.
