Installing the Hardware

Preparing the Server

Before installing the controller in the server, back up all data. This step is mandatory if you are moving non-arrayed SCSI drives to a Smart Array controller, because data is not preserved during a move between array controllers and non-array controllers.

WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with the computer before attempting the installation.

Many computers are capable of providing energy levels that are considered hazardous, and are only intended to be serviced by qualified personnel trained in dealing 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.

If the server supports hot-pluggable devices, go directly to the “Installing the Smart Array Controller” section.

To prepare a server that does not support hot-pluggable devices:

1.Close all applications.

2.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 unit to be powered back up. This precaution ensures that the system will not erroneously mark the drives as failed.

3.Power down any peripheral devices that are attached to the server.
