Nortel Networks BCM1000 manual Removing the hard disk, Replacing the hard disk

174Chapter 16 Replacing the hard disk

Warning: Maintain a current backup of your system.

When you replace the hard disk in a single disk system, you must restore the Business Communications Manager system programming from the backup.

Warning: Mirrored disk systems do not replace the need to have current BRU backups that you store in a secure remote location.

Caution: Use only a Nortel Networks approved upgrade or replacement kits.

Remember to take suitable precautions when working inside the Business Communications Manager base unit. Maintain a clean and static-safe site.

Danger: Electrical shock warning

Disconnect the telephone and network cables, and then the power cord before opening the base unit.

Read and follow all instructions carefully.

Caution: Do not use an electric screwdriver near the hard disk. You can lose the information stored on the disk.

Shock can damage the hard disk. Do not drop or hit the hard disk drive.

Removing the hard disk

The hard disk brackets are attached to the hard disk and the floor of the BCM1000. When you want to replace a hard disk, you remove both the brackets and the disk, or disks, as one unit, so they are easier to work with.

Warning: Ensure that you put all equipment on a static-free surface when you are working with it. Boards that you need to remove to access parts of the interior must be put into a static-free bag until you are ready to replace them in the unit.

The following steps describe that process for removing the bracket and hard disk unit.

1If you still have access to the Unified Manager, shut down the system by following the instructions in “Shutting down the system software” on page 168. Otherwise, skip to step 2.

2Set up the BCM1000 for maintenance, as described in “Shutting down the system hardware” on page 169.

3Inside the BCM1000, disconnect the hard disk power cables and ribbon cables.
