The Boot Block Status and Overwrite Password screen
(Figure 42) is typically not used. This screen provides
a method by which the bootcode can be updated on the
H2TU-C. The bootcode is seldom changed with new
download code. The bootcode is the small piece of code
that allows firmware upgrades on the H2TU-C unit. If it
becomes corrupted, the H2TU-C will require factory
service to restore it to a functional state. However, in the
rare case to provide some new bootcode feature, this
screen may be required to allow the bootcode to be
overwritten by the newly downloaded firmware.

WARNING: Overwriting the boot code involves some risk! Since
the boot block is the small piece of code responsible for allowing
firmware upgrades, overwriting the boot code with incorrect or
incomplete code will render this linecard useless and will require
factory service to restore the linecard to an operational state.
