Completing the parts replacement

CAUTION:
After replacing a CRU, reinstall all protective covers, including the computer cover, before connecting
power and operating the computer. This action is important to help prevent unexpected electrical
shock and help ensure the containment of an unexpected fire that could happen under extremely rare
conditions.
After completing the installation or replacement for all parts, pivot the drive bay assembly inward, reinstall the
front bezel, reinstall the computer cover, and reconnect cables. Depending on the parts you installed or
replaced, you might need to confirm the updated information in the Setup Utility program. Refer to "Using the
Setup Utility program" on page 65.
