Figure 132 Install a primary hard disk into the RAID hard disk cage
Installing a mirror hard disk into a RAID hard disk cage
Use this procedure to install the mirror hard disk into the RAID hard disk cage for the BCM200
and BCM400 systems. Use this procedure if you need to replace a faulty mirror hard disk.
Nortel recommends that you replace a 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.
Note: For a RAID upgrade kit, the mirror disk and primary disk IDE ribbon cables are
preinstalled. If applicable, install the programmed hard disk from your single disk system
into the RAID hard disk cage (use as the primary disk; see
).
Note: For a BCM200 system, orient the hard disk so that the power and IDE connectors
are on the bottom and opposite to the hard disk cage lift tab (see
).
For a BCM400 system, orient the hard disk so that the power and IDE connectors are on
the bottom and on the same side as the hard disk cage lift tab (see
).
