Figure 128   Remove the primary hard disk from the RAID hard disk cage

Place the primary hard disk on a flat, clean, and static-free surface.

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.
