3 Installing the Smart Array 5i Plus Controller and Battery Backed Write Cache Enabler WARNING: To reduce the risk of personal injury or damage to the equipment, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. Many servers are also capable of producing energy levels that are considered hazardous. These servers are to be serviced by qualified personnel trained to deal with these hazards. Do not remove enclosures or attempt to bypass any interlocks that may be provided for the purpose of removing these hazardous conditions. Consult the safety information and user documentation provided with your server before attempting the installation. To install the Smart Array 5i Plus Controller and Battery Backed Write Cache Enabler: 1. Back up all data. This step is mandatory. CAUTION: Back up all data stored on existing drives before installing the controller. All data stored on non-array drives is destroyed when the new controller is installed. 2. Close all applications. 3. Power down the server. CAUTION: In systems using external data storage, be sure that the server is the first unit powered down and the last to be powered back up. Doing this ensures that the system will not erroneously mark the drives as failed. Compaq Smart Start 5i Plus Controller and Battery Backed Write Cache Enabler User Guide 3-1
