This section explains how to replace a defective drive carrier module.
Caution: Follow electrostatic discharge (ESD) precautions while replacing the drive
carriers. Avoid contact with the backplane components and module connectors.
Note: Replace disk drive modules one at a time.
To remove a drive carrier module from the D-brick2 enclosure, follow these steps:
1. Make sure that enough disk drives and dummy drives are available to occupy all
bays.
2. Ensure that users are logged off of the affected systems; back up data if necessary.
3. If the drive module is locked, insert the Torx screwdriver into the anti-tamper lock
and turn it 90 degrees counterclockwise. The indicator in the drive carrier module
turns black when the drive is unlocked. See Figure 12-20.
