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.
