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.
