Replacing a RAID Controller Module
You must shut down the system before removing a RAID controller module (by unmounting all drives on the controller you are not changing, then shutting down and removing the power cords). See the document “Using RAID Admin and Disk Utility” on the CD that came with your system for shutdown instructions. When a controller module is out of the system (or has failed), the drive modules controlled by that card are not active and do not lose data stored on the drives.
Follow these steps to replace a RAID controller module.
1Push the two latches on the front of the module apart and use them to pull the unit out of the system. If the latches have small tabs on the inside surface, slide those tabs toward you to open the latches fully.
Push the two latches on the controller module outward to release it and then pull the module out of the unit.
2Remove the packaging from the new controller module. Hold the module by the latches and carefully slide it into the system until it clicks into place.
Make sure the controller module engages the plastic guides on the inside of the unit.
Push the controller module into the unit and squeeze the two latches together to seat the module.
