4-2 Compaq Smart Array 431 Controller User Guide
Preparing the Server
To prepare the server for Smart Array 431 Controller installation:
1. Perform a normal system shutdown.
CAUTION: If you will be moving non-arrayed SCSI drives to the Smart Array 431
Controller, you must first back up all of your data. Data is not preserved when
drives are moved between array controllers and non-array controllers.
CAUTION: In systems using external data storage, be sure the server is the first
unit powered down and the last to be powered back up. This will ensure that the
system will not erroneously mark the drives as “failed.”
2. Turn OFF the server.
3. Turn OFF any peripheral devices attached to the server.
4. Unplug the AC power cord from the outlet, then from the server.
IMPORTANT: If you will be replacing an existing Smart Controller with a new Smart Array
431 Controller, refer to the External Cabling section later in this chapter to determine the
external cabling requirements.
5. Disconnect any peripheral devices from the server.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the
internal system components and hot-plug hard drives to cool before touching.
6. Remove the access panel.
Installing the Smart Array 431 Controller
Use the following procedure to install the Smart Array 431 Controller into a
Compaq Server.
1. Select an available PCI slot.
2. Remove the slot cover. Save the retaining screw, if necessary.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be
sure you are properly grounded before beginning this procedure. See Appendix
B for ESD information.
3. Press the Smart Array 431 Controller firmly into the slot so the contacts
on the board edge seat fully in the system board connector.
