Sun GigabitEthernet PCI Adapter
Product Notes
These release notes provide the latest software information about the Sun
GigabitEthernet PCI Adapter 1.0. It is a supplement to the Sun GigabitEthernet PCI
Adapter 1.0 User’s Guide.
Quick Installation Instructions
This section provides you an overview of what you must do to install and configure
the Sun Gigabit Ethernet PCI Adapter. For more detailed instructions, refer to the
Sun GigabitEthernet PCI Adapter 1.0 User’s Guide.
▼To Install the Adapter
1. Shutdown and power off the system that will receive the adapter(s).
2. Install Gigabit Ethernet adapter into appropriate slot(s) within your system.
3. Power on the system and watch for the Gigabit adapter device information to be
displayed on the system console. If you don’t see the adapter, you may need to
repeat step 1 to ensure that the adapter has been properly seated.
2Sun GigabitEthernet PCI Adapter 1.0 Product Notes • August 1997
▼To Install the Software
1. Become root.
2. Place the CD-ROM into the CD-ROM drive.
3. Mount the CD-ROM on a local directory.
If the Volume Manager (vold) is running, on your machine, then the CD-ROM is
mounted automatically under /cdrom/sungige_1_0 when it is loaded in the drive
4. Access the package directory.
5. Install the software by entering pkgadd -d . (don’t forget the dot):
The screen displays a list of packages available for installation:
6. Press Return.
The pkgadd command starts the installation script.
7. Respond to the prompts in the script.
#cd /cdrom/sungige_1_0/Product
#pkgadd -d .
The following packages are available:
1 SUNWvge Sun GigabitEthernet Adapter 1.0
(sparc) 1.0.0
2 SUNWvts Online Validation Test Suite 2.0
(sparc) 2.1, REV=35.97.05.30
Select package(s) you wish to process (or ‘all’ to process all
packages). (default: all) [?, ??, q]

8. When you have finished loading the software, unmount the CD-ROM directory:
If the automounter fails to flush a previous mount point, you may see the following
directory:
If this should happen, remove the empty directory.
▼Configure the Host Files
1. Enter echo <interface-name>/etc/hostname.vge0.
The variable <interface-name> represents the name to be associated with the first
gigabit ethernet adapter (for example,
echo myhostname-ge0 /etc/hostname.vge0)
2. Assign the IP address by using vi or a similar text editor to edit the /etc/hosts
file.
For the example in Step 1, to assign the IP address 192.170.87.32 to the interface
myhostname-ge0, you would add the following entry to your /etc/hosts file:
3. Reboot your system.
#cd /
#eject /cdrom
/cdrom/sungige_1_0#1
#rmdir /cdrom/sungige_1_0#1
192.170.87.32 myhostname-ge0
#reboot -- -r

Documentation Updates
This section corrects or updates the Sun GigabitEthernet PCI Adaper 1.0 User’s Guide.
Hardware Requirements
The Sun Gigabit Ethernet PCI Adapter 1.0 User's Guide incorrectly states that the PCI
adapter will be supported on the Sun Ultra2. The PCI adapter will be supported on
the Sun Ultra Enterprise 3000 and Sun Ultra Enterprise 4000 and 5000 systems with
PCI I/O cards.
The Ultra Enterprise systems will support 2 Gigabit Ethernet cards.
Installation Correction
On page 6 of Sun Gigabit Ethernet PCI Adapter 1.0 User's Guide, Step 8 in the section
“To Install the Software,” should be amended to include the following:
When you have finished loading the software, unmount the CD-ROM director:
If the automounter failed to flush a previous mount point, you may see the
following directory:
If this should happen, remove the empty directory.
On pages 6 and 7, a textbox shows the command boot -- -r. The correct
command in both instances is as follows:
#cd /
#eject /cdrom
/cdrom/sungige_1_0#1
#rmdir /cdrom/sungige_1_0#1
#reboot -- -r
Sun GigabitEthernet PCI Adapter Product Notes 5
LED Indicators
An explanation of the LED indicators was omitted from the Sun GigabitEthernet PCI
Adapter 1.0 User’s Guide.TABLE 1 explains the LED indicators on the adapter.
GigabitEthernet Link Negotiation
The default configuration for link negotiation is auto. With this setting, the PCI
adapter will use IEEE 802.3z (draft) link negotiation.
If you are connecting the adapter to GigabitEthernet equipment that does not
support link negotiation or if there is a problem establishing a link between the two
devices, link negotiation can be turned off. See “Configuring Driver Parameters” on
page 6 for instructions on how to change the settings. Be sure that both devices are
set to the same speed and duplex configuration.
Purchasing Fiber Cables
You can purchase fiber cables directly from Sun Microsystems, Inc. using the
following part numbers:
■2-meter fiber cable X973A
■15-meter fiber cable X978A

1000BASE-SX Link Characteristics (IEEE P802.3z
draft)
TABLE 2 has been updated to reflect changes in the latest draft from IEEE. TABLE 2
replaces Table B-1 in the Sun GigabitEthernet PCI Adapter User’s Guide
Configuring Driver Parameters
Two new capabilities have been added to the parameters you can change using the
ndd utility: nic_tracing and link_negotiation. The following procedure
reflects these changes and replaces the section by the same name in the Sun
GigabitEthernet PCI Adaper 1.0 User’s Guide.
▼To Temporarily Change a Parameter
Use the ndd(1M) utility to temporarily change a parameter. This change is lost when
you reboot the system.
●To access the parameters you can change using ndd type the following command:
The system returns the following:

Sun GigabitEthernet PCI Adapter Product Notes 7
TABLE 3 explains the available parameters and shows the default value as well as the
minimum and maximum allowed values of each.
●To change the default settings, use the following format:
Open Issues
This section addresses Sun GigabitEthernet PCI adapter issues that were not
resolved at the time the Sun GigabitEthernet PCI Adapter 1.0 User’s Guide was printed.
