Card Features
The copper Gigabit Ethernet PCI Express card includes these features:
•Gigabit Ethernet (1000Base-T), Fast Ethernet (100Base-TX), Ethernet (10Base-T)
•Quad Ethernet ports
•Full-duplex and Simplex Gigabit Ethernet interface as defined in the IEEE P802.3ab
approved standard
•Dual, high-speed RISC processor per channel for advanced packet classification
•Hardware acceleration that can off-load tasks from the host processor. The
controllers can off-load TCP/UDP/IP checksum calculations and TCP
segmentation.
•Support for Jumbo Frames (9KB)
Note: The hardware MAC addresses for the four ports are lowest at the top of the card
and highest at the bottom of the card.
For full technical specifications of the card, see Appendix A, “Specifications”.
The cabling for the Gigabit Ethernet card is described in the following sections:
The Copper Gigabit Ethernet card is implemented using twisted pair cable. The cable,
which is not included in the shipment, must be Category-5 cable plant (4-pair) with an
RJ45 UTP connector at each end. Table 1-1 lists the SGI twisted pair cables. The operating
range for 1000-Base-T is up to 100 m (328 ft).
To achieve the longer distances available with 1000-Base-T,use a switchwith1000-Base-T
ports.

Installing the Card
Chapter 2
This chapter shows you how to connect the copper Gigabit Ethernet card to a network,
and how to configure your system for the card.
Following is a description of each section:
•“Installing the Card” on page 5
•“Connecting to the Network” on page 5
The installation instructions for the Gigabit Ethernet card are different for different
systems. Refer to the following sources for installation instructions:
•Altix XE250: See the instructions for installing a PCI-E card in the user’s or owner’s
guide that came with your system.
•Altix XE310: See the instructions for installing a PCI-E card in the user’s or owner’s
guide that came with your system.
•Altix XE320: See the instructions for installing a PCI-E card in the user’s or owner’s
guide that came with your system.
Connecting to the Network
To connect your copper Gigabit Ethernet card to a network, insert the RJ45 connector on
one end of the copper cable into the Gigabit Ethernet card, as shown in Figure 2-1. Make
sure the connector is inserted completely into the jack, and then insert the connector on
the other end of the copper cable into the jack on the Ethernet switch, or another
computer system (as appropriate).

2: Connecting the Gigabit Ethernet Card to a Network
Note: If your network connects to an Ethernet switch, consult the operating manual for
the switch to ensure that the switch port is enabled and configured correctly.

3.Operating the Gigabit Ethernet Card
This chapter describes various issues that may occur when using a Gigabit Ethernet
network. It includes the following sections:
•“Verifying Functionality” on page 7
•“Resetting the Card” on page 11
•“Configuration Parameters” on page 12
Verifying Functionality
This section explains the following:
•“Using LEDs to Determine Card Functionality” on page 8
•“Verifying Card Recognition” on page 8
•“Verifying Card Configuration and Enabling” on page 9

3: Operating the Gigabit Ethernet Card
Using LEDs to Determine Card Functionality
The copper Gigabit Ethernet cards have light-emitting diodes (LEDs) that indicate
whether the card is configured correctly and connected to an active Ethernet, as
discussed in the following sections.
The copper Gigabit Ethernet card has three LEDs per ports. Table 3-1 describes the
functions of these LEDs.

100Mbit/s: Turns on Green.
10Mbit/s: Turns off
ConnectorsShielded RJ-45
Verifying Card Recognition
To verify that the operating system has located the Gigabit Ethernet card, use the Linux
PCI utilities lspci(8) command, as follows:
sit0 Link encap:IPv6-in-IPv4
NOARP MTU:1480 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
For more information on ifconfig, see the ifconfig(8) man page.
Resetting the Card
In the unlikely event that you need to reset the copper Gigabit Ethernet card, enter the
following:
ifconfig <interface> down
ifconfig <
where interface is name of the interface. This is usually a driver name followed by a
unit number, for example, ifconfig eth0 down, for the first Ethernet interface.
007-5515-00111
interface> up
3: Operating the Gigabit Ethernet Card
For more information on ifconfig, see the ifconfig(8) man page.
Configuration Parameters
Configuration changes for Ethernet devices drivers are made by means of the
ethtool(8) command. The ethtool command works with all Linux Ethernet drivers.
In general, each feature has a query and a modify variant. If you are wondering
whether the current driver and ethtool support a specific feature, attempt to run the
query option first, an example is, as follows:
# ethtool -a eth2
Pause parameters for eth2:
Autonegotiate: on
RX: on
TX: on
This shows the current settings of the pause (or flow control) parameters. You can then
change these parameters with the ethtool -A option.
As with any system configuration changes, make sure to have a back out strategy, read
the most recent documentation for potential changes and pitfalls, and consult with a
relevant Linux archives for examples of common usage.
