Preface

This manual is the primary reference and user’s guide for the ServeRAID

M5014 SAS/SATA controller and the ServeRAID M5015 SAS/SATA

controller. It contains installation instructions and specifications for the

controller, and it explains how to install and use the ServeRAID M5000

Series Battery Assembly with the ServeRAID M5014 SAS/SATA

controller and the ServeRAID M5015 SAS/SATA controller. In addition, it

explains how to install the ServeRAID M5000 Series Advanced Feature

Key on the ServeRAID M5015 SAS/SATA controller.

For details on how to configure the storage adapter, refer to the

ServeRAID-M Software User’s Guide. For information about the

operating system drivers, refer to the ServeRAID-M Device Driver

Installation User’s Guide.

viii Preface

Protecting against Electrostatic Discharge – Static electricity can

harm delicate components inside your computer. To prevent static

damage, discharge static electricity from your body before you touch any

of your computer’s electronic components, such as the microprocessor.

You can do so by touching an unpainted metal surface, such as the metal

around the card-slot openings at the back of the computer.

As you continue to work inside the computer, periodically touch an

unpainted metal surface to remove any static charge your body may

have accumulated. In addition to the preceding precautions, you can also

take the following steps to prevent damage from electrostatic discharge:

•

When unpacking a static-sensitive component from its shipping

carton, do not remove the component from the antistatic packing

material until you are ready to install the component in your

computer. Just before unwrapping the antistatic packaging, be sure

to discharge static electricity from your body.

•

When transporting a sensitive component, first place it in an

antistatic container or packaging.

Handle all sensitive components in a static-safe area. If possible, use

antistatic floor pads and workbench pads.
