Preface

This guide provides instructions for installing both the hardware and softwarefor

the Sun Dual 10GbE XFP PCI Express card. This manual also describes how to

configure the nxge driver,which controls the card.

Theseinstructions are designed for enterprise system administrators with experience

installing network hardware and software.

Note – In this document the term x86 refers to 64-bit and 32-bit systems

manufactured using processors compatible with the AMD64 or Intel Xeon/Pentium

product families. For supported systems, see the Solaris Hardware Compatibility Guide.

How This Document Is Organized

Chapter 1 provides an overview of the Sun x8 Express Dual 10 Gigabit Ethernet

Fiber XFP Low Profile Adapter.

Chapter 2 explains how to install the nxge device driver software in a Solaris

SPARC,Solaris x86, or Linux environment.

Chapter 3 describes how to install the Sun x8 Express Dual 10 Gigabit Ethernet Fiber

XFP Low Profile Adapter in your system and verify that it has been installed

correctly.

Chapter 4 describes how to edit the network host files after the adapter has been

installed on your system.

Chapter 5 explains how to set the nxge device driver parameters to customize each

device in your system.
