Nortel Networks 400 4.0, BCM200 manual Provides an overview of the hard disk replacement process

254Chapter 22 Replacing the hard disk

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.
