N0060612

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 

.

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

Use this procedure to remove a standard or RAID configuration hard disk cage from the BCM200 
main unit (see also 

).  

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.

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.

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.
