Removing a primary hard disk from a RAID hard disk cage
Use this procedure to remove the primary hard disk from the RAID hard disk cage for the
BCM200 and BCM400 system. Use this procedure if you need to replace a faulty hard disk. If a
primary hard disk fails, the mirror hard disk assumes control and service remains uninterrupted.
Nortel recommends that you replace the failed primary hard disk to retain full redundancy.
Replace the failed primary hard disk during a period of low call traffic.
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.
