Nortel Networks 400 4.0, BCM200 manual Removing a hard disk cage

258Chapter 22 Replacing the hard disk

Note: RAID disk mirroring takes up to 3 hours to complete. The BCM system continues to operate normally during the disk mirroring process. However, because disk mirroring occupies computing resources, Nortel recommends that you perform disk mirroring during a period of low call traffic.

Note: If this is the first time installation of the RAID configuration, both primary and mirror status LEDs are green.

Removing a hard disk cage

Use the procedures in this section to remove a hard disk cage from either the BCM200 or BCM400 system. When a hard disk causes problems or fails, remove the hard disk cage from the BCM200 main unit or the BCM400 main unit. Remove the hard disk cage for RAID upgrades, or for hard disk or RAID card replacement conditions.

For information on how to determine if you have a faulty hard disk, refer to “Monitoring standard configuration hard disk status using Element Manager” on page 218 or “RAID disk mirroring” on page 221.

This section provides the following procedures for removing a hard disk cage from the BCM200 and BCM400 main unit.

•“Removing a hard disk cage from a BCM200 main unit” on page 258

•“Removing a hard disk cage from a BCM400 advanced function tray” on page 260

Warning: Maintain a current backup of your system configuration on a separate backup network server. Restore the current backup configuration data to a replacement hard disk. For further information on how to perform a backup and restore, refer to the BCM 4.0 Administration Guide.

Removing a hard disk cage from a BCM200 main unit

Use this procedure to remove a standard or RAID configuration hard disk cage from the BCM200 main unit (see also “Replacing a hard disk in the hard disk cage” on page 265).

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.
