Removing a mirror hard disk from a RAID hard disk cage

Use this procedure to remove the mirror hard disk from the RAID hard disk cage for the BCM200 and BCM400 system. Use this procedure if you need to replace a faulty mirror hard disk.

Nortel recommends that you replace the failed mirror hard disk to retain full redundancy. Replace the failed mirror hard disk during a period of low call traffic. If you choose to remove both the primary and mirror hard disks from the hard disk cage, place an identifying mark on the primary hard disk to ensure correct installation.

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.
