ServeRAID M5014/M5015 SAS/SATA Controller User’s Guide iii
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.
Audience
This document assumes that the reader is familiar with RAID controllers
and related support devices. The people who benefit from this book are:

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.
