Nortel Networks 400 4.0, BCM200 manual To install a primary hard disk into a RAID hard disk cage

270Chapter 22 Replacing the hard disk

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.

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 132).

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 130).

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 131).

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.

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

1Position the primary hard disk into the top position of the RAID hard disk cage.

2Align 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 131).

3Connect the correct primary IDE ribbon cable connector to the primary hard disk.
