available for the controller.

Expansion board problems

System requests recovery method during expansion board replacement

When replacing an expansion board on a BitLocker™-encrypted server, always disable BitLocker™ before

replacing the expansion board. If BitLocker™ is not disabled, the system requests the recovery method

selected when BitLocker™ was configured. Failure to provide the correct recovery password or passwords

results in loss of access to all encrypted data.

Be sure to enable BitLocker™ after the installation is complete.

For information on BitLocker™, see BitLocker™ for Servers on the Microsoft website

(http://www.microsoft.com).
