Downloading and Installing the Driver on a Linux Platform

1.Login to your system.

2.Download the driver RPM for your operating system: http://www.sun.com/download/products.xml?id=44eb1efd

For example:

nxge-1.0-1.x86_64.rpm

3.Discover the network interfaces before adding the package by using the ifconfig -acommand:

# ifconfig -a grep eth
eth0	Link encap:Ethernet	HWaddr 00:14:4F:20:F1:DC
eth1	Link encap:Ethernet	HWaddr 00:14:4F:20:F1:DD
eth2	Link encap:Ethernet	HWaddr	00:14:4F:20:F1:DE
eth3	Link encap:Ethernet	HWaddr	00:14:4F:20:F1:DF

4.Use the rpm tool to install the driver on SuSe and RedHat Linux.

#rpm -ivh /tmp/RHEL4U4-large/RPMS/x86_64/nxge-1.0-1.x86_64.rpm
