16 HP Smart Array 6400 Series Controllers User Guide CAUTION: In systems that use external data storage, be sure that the server is the first unit to be powered down and the last to be powered back up. Taking this precaution ensures that the system does not erroneously mark the drives as failed when the server is powered up. 3. Power down all peripheral devices that are attached to the server. 4. Unplug the AC power cord from the outlet and then from the server. 5. Disconnect all peripheral devices from the server. Installing the controller board WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with the server before attempting the installation. Many servers are capable of providing energy levels that are considered hazardous and are intended to be serviced only by qualified personnel who have been 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. 1. Remove or open the access panel. 2. Select an available 3.3-V PCI or PCI-X slot. 3. Remove the slot cover or open the hot-plug latch. Save the retaining screw if one is present. 4. Slide the controller board along the slot alignment guide, and press the board firmly into the slot so that the contacts on the board edge are properly seated in the system board connector. 5. Secure the controller board in place with the hot-plug latch or retaining screw. If there is a guide latch on the rear of the board, close the latch. 6. Connect storage devices to the controller ("Connecting storage devices" on page 17). NOTE: Drives that are to be grouped in the same array should all have comparable capacity for efficient use of total storage capacity.
