The recovery key/password is generated during BitLocker setup, and can be saved and printed after
BitLocker is enabled. When using BitLocker, always retain the recovery key/password. The recovery
key/password is required to enter Recovery Mode after BitLocker detects a possible compromise of
system integrity or firmware or hardware change.
For security purposes, follow these guidelines when retaining the recovery key/password:
•
Always store the recovery key/password in multiple locations.
•
Always store copies of the recovery key/password away from the server.
•
Do not save the recovery key/password on the encrypted hard drive.

Replacing the system battery
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before
touching them.
The server comes with a system battery (Panasonic BR2032) installed on the system board, which
supplies power to the real-time clock and has a lifespan of 3 to 5 years. If the server no longer
automatically displays the correct date and time, you might need to replace the battery. As a best
practice, use the Panasonic BR2032 battery to replace the old one.
