Chapter 22 Replacing the hard disk

N0060612

N0060612

Nortel recommends that you replace a failed primary hard disk to retain full redundancy. Replace
the failed primary hard disk during a period of low call traffic.

To install a primary hard disk into a RAID hard disk cage

1

Position the primary hard disk into the top position of the RAID hard disk cage.

2

Align the hard disk and hard disk cage retaining screw holes. Fasten the hard disk cage retainer
screws into both sides of the hard disk cage (see

Figure 132

).

3

Connect the correct primary IDE ribbon cable connector to the primary hard disk.

Caution: Use only Nortel-approved replacement components. Contact your account
representative for the current list of approved replacement parts.

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

Figure 133

).

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

Figure 131

).

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

Figure 132

).

Note: The hard disk storage capacity (in MB) for both primary and mirror hard disks must
be identical. Equipment provided by Nortel assures correct hard disk capacity
requirements.
