Figure 123 Hard disk replacement overview
Note: Maintain a current backup of your system
When you replace the hard disk, you need to restore the BCM system programming from
the backup using the backup and restore utility (BRU). If you do not have a current
backup, you must reenter configuration data. For further information on how to perform a
backup or restore, refer to the BCM 4.0 Administration Guide.
Caution: Do not use an electric or magnetized screwdriver near the hard disk. You can
lose the information stored on the disk. Shock can damage the hard disk. Do not drop or
hit the hard disk drive.
Warning: You must remove all of the connections to the BCM main unit base function
tray before you power the system down. Failure to disconnect lines before power down
can cause damage to the system.
Warning: Protect the hardware components against damage from electrostatic discharge.
Always wear a grounded wriststrap before you handle components. Always place the
components in a static-free container.
