Installing the Adapter
This chapter tells you how to install the Sun Quad FastEthernet PCI adapter in your
system and how to verify that it has been installed correctly.
Adding an Entry to the driver_aliases File
If your system is running the Solaris 2.5.1 Hardware: 4/97 operating environment,
you will need to add an entry to the /etc/driver_aliases file before installing
the Sun Quad FastEthernet PCI adapter. In future operating system releases, you
will not need to edit this file.
1. Check the /etc/driver_aliases file for the line required by the adapter.
# grep 'pci_pci "pci1011,25"' /etc/driver_aliases
If this line already exists in the driver_aliases file, you can proceed with the
adapter installation, which is described in the next section. Otherwise, you will need
to add this line to the file before installing the adapter.
2. Using a text editor, add the following line to the end of the
/etc/driver_aliases file.
pci_pci "pci1011,25"
Once you have added this line to the file, you can safely install the adapter.
5
Installing the Adapter
Note – Refer to your system installation or service manual for detailed instructions
for the following tasks.
1. Power off your system and open the system unit.
2. Attach the adhesive copper strip of the wrist strap to the metal casing of the
power supply. Wrap the other end twice around your wrist, with the adhesive side
against your skin.
3. Holding the PCI adapter by the edges, unpack and place it on an antistatic surface.
4. Remove the PCI filler panel from the slot in which you want to insert the Sun
Quad FastEthernet PCI adapter.
5. Holding the PCI adapter by the edges, align the adapter edge connector with the
PCI slot. Slide the adapter face plate into the small slot at the end of the PCI
opening.
6. Applying even pressure at both corners of the adapter, push the PCI adapter until
it is firmly seated in the slot.
Caution – Do not use excessive force when installing the adapter into the PCI slot.
You may damage the adapter’s PCI connector. If the adapter does not seat properly
when you apply even pressure, remove the adapter and carefully reinstall it again.
7. If necessary, reinstall the PCI filler panel in the unused PCI opening.
8. Detach the wrist strap and close the system unit.
9. Connect Ethernet cables to the Sun Quad FastEthernet PCI adapter and to an Ethernet network.
6 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
Verifying the Installation
After you have installed the Sun Quad FastEthernet PCI adapter, but before you boot

the Sun Quad FastEthernet PCI adapter:
ok show-devs
...
/pci@1f,2000/pci@2/SUNW,qfe@0,1
/pci@1f,2000/pci@2/SUNW,qfe@1,1
/pci@1f,2000/pci@2/SUNW,qfe@2,1
/pci@1f,2000/pci@2/SUNW,qfe@3,1
...
The SUNW,qfe@x,1 entries identify the adapter’s four Ethernet devices.
Note – If you do not see the devices listed, check that the adapter is properly seated
and, if necessary, reinstall the adapter.
Diagnostic Testing
For Sun Quad FastEthernet PCI adapter diagnostic testing, see Appendix D,
“Running Diagnostics Tests.”.
Chapter 2 Installing the Adapter 7
Examining Network Activity
After you have installed the Sun Quad FastEthernet PCI adapter, but before booting
the system, verify the installation by examining the network interfaces with the
OpenBoot PROM watch-net-all command.
Make sure that the interfaces are connected to an active network.
● Examine network activity and incoming network packets by typing
watch-net-all at the ok prompt.
The watch-net-all command monitors network traffic on all network interfaces
in the system. In the example below, the watch-net-all command tests all four of
the adapter ’s interfaces, two of which are connected to a network.
ok watch-net-all
/pci@1f,2000/pci@2/SUNW,qfe@0,1
Internal loopback test -- succeeded.
Transceiver check -- failed
/pci@1f,2000/pci@2/SUNW,qfe@1,1
Internal loopback test -- succeeded.
Transceiver check -- passed

Internal loopback test -- succeeded.
Transceiver check -- passed
Looking for Ethernet Packets.
'.' is a Good Packet. 'X' is a Bad Packet.
Type any key to stop.
.......................................
(Press any key to continue.)
In addition to testing the adapter’s interfaces, the watch-net-all command may
also test other network devices on the system.
Note – The network speed is the same as the speed of the network that your system
is connected. See the section “Forcing Network Speed Between 10 Mbps and 100
Mbps” on page 16 for more detailed information about speed selection.
8 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
Rebooting the System
After you have examined the network activity, perform a reconfiguration boot on
your system so the operating environment can recognize the Sun Quad FastEthernet
PCI adapter.
● Perform a reconfiguration boot on the system.
ok boot -r
Refer to the Solaris 2.x Peripheral’s Handbook for more information.

10 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
CHAPTER
3
Configuring the Driver Software
This chapter describes how to configure the driver software used by the Sun Quad
FastEthernet PCI adapter.
Installing the Driver Software
The Sun Quad FastEthernet 2.0 CD-ROM contains the software required by the Sun
Quad FastEthernet PCI adapter. Install the software driver packages as described in
the CD insert. (Future revisions of the Sun Quad FastEthernet software will also
work with your adapter.)
Before you can use the four channels of the adapter, you will need to create and edit
system host files, as described in the next section.
Configuring the Host Files
After installing the Sun Quad FastEthernet driver software, you must create a
hostname.qfe<num> file for the adapter’s Ethernet interfaces. You must also create
both an IP address and a host name for its Ethernet interfaces in the /etc/hosts
file.
11
1. At the command line, use the grep command to search the /etc/path_to_inst file for qfe devices.
# grep qfe /etc/path_to_inst
"/pci@1f,2000/pci@2/SUNW,qfe@0,1" 4 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@1,1" 5 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@2,1" 6 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@3,1" 7 "qfe"
In the example above, the four SUNW,qfe@x,1 instances are from a Sun Quad
FastEthernet PCI adapter installed in slot 2. For clarity, the instance numbers are
bold.
2. Create an /etc/hostname.qfe<num> file, where <num> corresponds to the
instance number of each interface you plan to use.
If you wanted to use all of the adapter’s interfaces in Step 1’s example, you would
need to create four files:
Filename Instance
Number
Adapter Ethernet Channel
(See
FIGURE 1-2 on page 2)
/etc/hostname.qfe4 40
/etc/hostname.qfe5 51
/etc/hostname.qfe6 62
/etc/hostname.qfe7 73
■ Do not create /etc/hostname.qfe<num> files for Sun Quad FastEthernet PCI
adapter channels you plan to leave unused.
■ The /etc/hostname.qfe<num> file must contain the hostname for the
appropriate network interface.
■ The host name should have an IP address and should be entered in the
/etc/hosts file.
■ The host name should be different from any other host name of any other
interface, for example: /etc/hostname.hme0 and /etc/hostname.qfe2
cannot share the same host name.
12 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
Using the instance examples in Step 1, the following example shows the four
/etc/hostname.qfe<num> files required for a system called zardoz that has a
Sun Quad FastEthernet PCI adapter (zardoz-11, zardoz-12, zardoz-13, and
zardoz-14).
# cat /etc/hostname.hme0
zardoz
# cat /etc/hostname.qfe4
zardoz-11
# cat /etc/hostname.qfe5
zardoz-12
# cat /etc/hostname.qfe6
zardoz-13
# cat /etc/hostname.qfe7
zardoz-14
3. Create an appropriate entry in the /etc/hosts file for each active qfe channel.
Using the example in Step 1, you will have:
# cat /etc/hosts
#
# Internet host table
#
127.0.0.1 localhost
129.144.10.57 zardoz loghost
129.144.11.83 zardoz-11
129.144.12.41 zardoz-12
129.144.13.67 zardoz-13
129.144.14.30 zardoz-14
4. Reboot your system.
Chapter 3 Configuring the Driver Software 13
Booting From the Network
To use a Sun Quad FastEthernet PCI adapter ethernet interface as the boot device,
perform the following tasks:
1. At the ok prompt type:
ok show-devs
The show-devs command lists the system devices. You should see the full path
name of the qfe devices, similar to the example below:
/pci@1f,2000/pci@2/SUNW,qfe@0,1

14 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
Post-Installation Procedures (Optional)
Perform the tasks in the following sections to customize the performance of the Sun
Quad FastEthernet PCI adapter.
Configuring Driver Parameters
The qfe device driver, which is loaded from the CD-ROM, controls the SUNW,qfe
Ethernet devices. The device driver automatically selects the link speed using the
auto-negotiation protocol with the link partner. (See “Auto-Negotiation” on
page 17.)
You can manually configure the qfe device driver parameters to customize each
SUNW,qfe device in your system in one of three ways:
■ Configure the qfe driver parameters generally for all SUNW,qfe devices in the
system by entering the parameter variables in the /etc/system file.
■ Set a parameter on a per-device basis by creating the qfe.conf file in the
/kernel/drv directory.
■ Use the ndd utility to temporarily change a parameter. This change is lost when
you reboot the system.
See Appendix C, “Configuring the Quad FastEthernet Device Driver Parameters,”
for more information.
Increasing TCP/IP Performance
The TCP/IP performance of the Sun Quad FastEthernet PCI adapter can be
increased by changing the TCP high water mark to 64K. This can be done with the
ndd utility as follows.
1. As superuser (root), type:
# ndd -set /dev/tcp tcp_xmit_hiwat 65535
# ndd -set /dev/tcp tcp_recv_hiwat 65535
# ndd -set /dev/tcp tcp_cwnd_max 65534
The changes take effect immediately and affect all the networking interfaces in the
system. The changes are lost when you reboot the system.
Chapter 3 Configuring the Driver Software 15
Forcing Network Speed Between 10 Mbps and 100 Mbps
1. At the ok prompt, use the show-devs command to list the system devices.
You should see the full path names of the qfe devices, similar to the example below:
/pci@1f,2000/pci@2/SUNW,qfe@0,1
/pci@1f,2000/pci@2/SUNW,qfe@1,1
/pci@1f,2000/pci@2/SUNW,qfe@2,1
/pci@1f,2000/pci@2/SUNW,qfe@3,1
2. Type:
ok nvedit
3. Type the following, pressing the Return key at the end of line 0:
0: probe-all install-console banner
1: apply transfer-speed=10 (full path name of a qfe device)
Note – If you already have commands in NRAM, append these lines to the end of
the file.
4. Press the Control-C keys after typing (full path name of a qfe device) .
You will need to perform Steps 2 to 4 to set the network speed for each qfe channel.
Note – In the above example, the speed is forced to 10 Mbps. To force the speed to
100 Mbps, replace 10 with 100.
5. At the ok prompt type:
ok nvstore
ok setenv use-nvramrc? true
6. Reboot your system.
See Appendix C, “Configuring the Quad FastEthernet Device Driver Parameters,”
for more information on forcing network speed.
16 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
Auto-Negotiation
A key feature of the Sun Quad FastEthernet PCI adapter is auto-negotiation. The
auto-negotiation protocol, as specified by the 100BASE-T standard, selects the
operation mode (half-duplex or full-duplex), and the auto-sensing protocol selects
the speed (10 Mbps or 100 Mbps) for the adapter.
The link speed and modes supported by the Sun Quad FastEthernet PCI adapter are
listed as follows in decreasing order of priority:
■ 100 Mbps, full-duplex
■ 100 Mbps, half-duplex
■ 10 Mbps, full-duplex
■ 10 Mbps, half-duplex
When the system is booted, the Sun Quad FastEthernet PCI adapter advertises these
capabilities to the Link Partner at the other end of the link (a hub, switch, or another
network interface card (NIC) in a host system). If the Link Partner also supports
auto-negotiation, it will advertise its capabilities over the link. The common highest
priority mode supported by both sides will be selected automatically for the link
operation.
The qfe device driver operates the SUNW,qfe devices by default in half-duplex
mode only. If the Sun Quad FastEthernet PCI adapter is connected to a remote
system or interface that is not capable of auto-negotiation, your system
automatically selects the speed and half-duplex mode.
If the Sun Quad FastEthernet PCI adapter is connected to a link partner with which
the auto-negotiation protocol fails to operate successfully, you can configure the
device to not use this protocol and force the driver to set up the link in the mode and
speed of your choice.
Chapter 3 Configuring the Driver Software 17
local-mac-address Property
Each of the network interfaces of the Sun Quad FastEthernet PCI adapter have been
assigned a unique MAC (Media Access Control) address, which represents the 48-bit
ethernet address for that channel. The OpenBoot firmware reports this MAC address
via the local-mac-address property in the device nodes corresponding to the
network interfaces.
A system is not obligated to use this assigned MAC address if it has a system-wide
MAC address. In such cases, the system-wide MAC address applies to all network
interfaces on the system.
The device driver, or any other adapter utility, can use the network device's MAC
address (local-mac-address) while configuring it. In the Solaris 2.6 operating
system (and later Solaris revisions), you will be able to use a channel's MAC address
when booting over the network.
The mac-address property of the network device specifies the network address
(system-wide or local-mac-address) used for booting the system. To start using
the MAC addresses assigned to the network interfaces of the Sun Quad FastEthernet
PCI adapter, set the NVRAM configuration variable local-mac-address? to
true.
ok setenv local-mac-address? true

Configuring the Quad FastEthernet Device Driver Parameters
The qfe device driver controls the Sun Quad FastEthernet PCI adapter’s SUNW,qfe
Ethernet devices. You can manually configure the qfe device driver parameters to
customize each SUNW,qfe device in your system. This appendix provides an
overview of the internal transceiver used in the adapter, lists the available qfe
device driver parameters, and describes how you can configure these parameters.
Internal Transceiver
The four SUNW,qfe channels provide 10BASE-TX or 100BASE-T networking
interfaces using the PCI Fast Ethernet and Expansion (PFEX) ASIC and an internal
transceiver. The driver automatically sets the link speed to 10 or 100 Mbps and
conforms to the 100BASE-T IEEE 802.3u Ethernet standard. The PFEX ASIC provides
the PCI interface and Media Access Control (MAC) functions. The internal
transceiver, which connects to an RJ-45 connector, provides the physical layer
functions.
The internal transceiver is capable of all the operating speeds and modes listed in
the section, “Auto-Negotiation” on page 17. The internal transceiver performs autonegotiation with the remote end of the link (link partner) to select a common mode
of operation.
The internal transceiver also supports a forced mode of operation. You can select the
speed and mode using the ndd utility, by editing the /etc/system file, or creating
a qfe.conf file.

Inter-Packet Gap Parameters
The PCI Fast Ethernet and Expansion (PFEX) ASIC supports the programmable
Inter-Packet Gap (IPG) parameters ipg1 and ipg2. The total IPG is the sum of ipg1
and ipg2. The total IPG is 9.6 microseconds when the link speed set, by the autonegotiation protocol, is 10 Mbps. When the link speed is 100 Mbps, the total IPG is
0.96 microseconds.
Appendix B Configuring the Quad FastEthernet Device Driver Parameters 25
TABLE B-3 lists the default values and allowable values for the inter-packet gap (IPG)
parameters, ipg1 and ipg2.
TABLEB-3 Read-Write Inter-Packet Gap Parameter Values and Descriptions
Parameter Values
(Byte-time)
ipg1 0, 255 ipg1 = 8 (default at initialization)
ipg2 0, 255 ipg2 = 4 (default at initialization)
Description
By default, the driver sets ipg1 to 8-byte time and ipg2 to 4-byte time, which are
the standard values. (Byte time is the time it takes to transmit one byte on the link,
with a link speed of either 100 Mbps or 10 Mbps.)
If your network has systems that use longer IPG (the sum of ipg1 and ipg2) and if
those machines seem to be slow in accessing the network, increase the values of
ipg1 and ipg2 to match the longer IPGs of other machines.
Defining an Additional Delay Before Transmitting a Packet Using lance_mode and ipg0
The PCI Fast Ethernet and Expansion (PFEX) ASIC supports a programmable mode
called lance_mode. The ipg0 parameter is associated with lance_mode.
After a packet is received with lance_mode enabled (default) an additional delay is
added by setting the ipg0 parameter before transmitting the packet. This delay, set
by the ipg0 parameter, is in addition to the delay set by the ipg1 and ipg2
parameters. The additional delay set by ipg0 helps to reduce collisions. Systems
that have lance_mode enabled might not have enough time on the network.
If lance_mode is disabled, the value of ipg0 is ignored and no additional delay is
set. Only the delays set by ipg1 and ipg2 are used. Disable lance_mode if other
systems keep sending a large number of back-to-back packets.
You can add the additional delay by setting the ipg0 parameter from 0 to 31, which
is the nibble time delay. Note that nibble time is the time it takes to transfer four bits
on the link. If the link speed is 10 Mbps, nibble time is equal to 400 ns. If the link
speed is 100 Mbps, nibble time is equal to 40 ns.
For example, if the link speed is 10 Mbps, and you set ipg0 to 20 nibble times,
multiply 20 by 400 ns to get 800 ns. If the link speed is 100 Mbps, and you set ipg0
to 30 nibble-times, multiply 30 by 40 ns to get 120 ns.

Appendix B Configuring the Quad FastEthernet Device Driver Parameters 29
Setting qfe Driver Parameters
You can set the qfe device driver parameters in three ways (ndd, /etc/system,
and qfe.conf), depending on your needs. To set parameters that are valid until you
reboot the system, use the ndd utility. Using ndd is a good way to test parameter
settings.
To set parameters so they remain in effect after you reboot the system:
■ Add the parameter values to the /etc/system file when you want to configure
parameters for all devices in the system.
■ Create a /kernel/drv/qfe.conf file and add parameter values to the this file
when you need to set a particular parameter for a device in the system.
Setting Parameters Using the ndd Utility
Use the ndd utility to configure parameters that are valid until you reboot the
system. The ndd utility supports any networking driver, which implements the Data
Link Provider Interface (DLPI).
The following sections describe how you can use the qfe driver and the ndd utility
to modify (with the -set option) or display (without the -set option) the
parameters for each SUNW,qfe device.
Identifying Device Instances
Before you use the ndd utility to get or set a parameter for a qfe device, you must
specify the device instance for the utility since there will be at least four SUNW,qfe
devices.
30 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
▼ To Specify the Device Instance for the ndd Utility
1. Check the /etc/path_to_inst file to identify the instance associated with a particular device.
# grep qfe /etc/path_to_inst
"/pci@1f,2000/pci@2/SUNW,qfe@0,1" 4 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@1,1" 5 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@2,1" 6 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@3,1" 7 "qfe"
In the example above, the four SUNW,qfe@x,1 instances are from a Sun Quad
FastEthernet PCI adapter installed in slot 2. For clarity, the instance numbers are
bold.
2. Use the instance number to select the device.
# ndd -set /dev/qfe instance instance#
The device remains selected until you change the selection.
Non-Interactive and Interactive Modes
You can use the ndd utility in two modes:
■ Non-interactive
■ Interactive
In non-interactive mode, you invoke the utility to execute a specific command. Once
the command is executed, you exit the utility. In interactive mode, you can use the
utility to get or set more than one parameter value. (Refer to the ndd (1M) man page
for more information.)
Appendix B Configuring the Quad FastEthernet Device Driver Parameters 31
Using the ndd Utility in Non-Interactive Mode
This section describes how to modify and to display parameter values.
● To modify a parameter value, use the -set option.
If you invoke the ndd utility with the -set option, the utility passes value, which
must be specified down to the named /dev/qfe driver instance, and assigns it to
the parameter:
# ndd -set /dev/qfe parameter value
● To display the value of a parameter, specify the parameter name (and omit the
value).
When you omit the -set option, a query operation is assumed and the utility
queries the named driver instance, retrieves the value associated with the specified
parameter, and prints it:
# ndd /dev/qfe parameter
Using the ndd Utility in Interactive Mode
● To modify a parameter value in interactive mode, specify ndd /dev/qfe,as
shown below.
The ndd utility then prompts you for the name of the parameter:
# ndd /dev/qfe
name to get/set? (Enter the parameter name or ? to view all parameters)
After entering the parameter name, the ndd utility prompts you for the parameter
value (see
32 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
TABLE B-1 through TABLE B-8).
● To list all the parameters supported by the qfe driver, type ndd /dev/qfe \?.

Setting Parameters Using the
qfe.conf File
You can also specify the properties described in the section, “Setting Parameters in
the /etc/system File,” on a per-device basis by creating a qfe.conf file in the
/kernel/drv directory. The properties set in the qfe.conf file will override the
parameters set in the /etc/system file. Use a qfe.conf file when you need to set
a particular parameter for a device in the system. The parameters you set are read
and write parameters that are listed in “Driver Parameter Values and Definitions” on
page 24.
The man pages for prtconf (1M), system (4) and driver.conf (4) include
additional details. The next section shows an example of setting parameters in a
qfe.conf file.
36 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
Setting ipg Driver Parameters Using a qfe.conf File
1. Obtain the hardware path names for the qfe devices in the device tree.
Typically the path names and the associated instance numbers will be present in the
/etc/path_to_inst file.
# grep qfe /etc/path_to_inst
"/pci@1f,2000/pci@2/SUNW,qfe@0,1" 4 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@1,1" 5 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@2,1" 6 "qfe"
"/pci@1f,2000/pci@2/SUNW,qfe@3,1" 7 "qfe"
■ In the above lines:
■ The first part within the double quotes specifies the hardware node name in the
device tree.
■ The second number is the instance number.
■ The last part in double quotes is the driver name.
■ In the device path name, the last component after the last / character and before
the @ character is the device name.
■ The path name before the last component is the parent name.
■ The comma separated numbers after the @ character at the end represent the
device and function numbers, which are together referred to as unit-address.
To identify a PCI device unambiguously in the qfe.conf file, use the name, parent
name, and the unit-address for the device. Refer to the pci(4) man page for more
information about the PCI device specification.
In the first line of the previous example:
■ Name = SUNW,qfe
■ Parent = /pci@1f,2000/pci@2
■ Unit-address = 0,1
In the second line in the previous example:
■ Name = SUNW,qfe
■ Parent = /pci@1f,2000/pci@2
■ Unit-address = 1,1
Appendix B Configuring the Quad FastEthernet Device Driver Parameters 37
In the third line in the previous example:
■ Name = SUNW,qfe
■ Parent = /pci@1f,2000/pci@2
■ Unit-address = 2,1
In the fourth line in the previous example:
■ Name = SUNW,qfe
■ Parent = /pci@1f,2000/pci@2
■ Unit-address = 3,1
2. Set the ipg1 and ipg2 parameters for the above four devices in the /kernel/drv/qfe.conf file.
name = “SUNW,qfe” parent = “/pci@1f,2000/pci@2” unit-address = “0,1” ipg1=20 ipg2=10;
name = “SUNW,qfe” parent = “/pci@1f,2000/pci@2” unit-address = “1,1” ipg1=20 ipg2=10;
name = “SUNW,qfe” parent = “/pci@1f,2000/pci@2” unit-address = “2,1” ipg1=20 ipg2=10;
name = “SUNW,qfe” parent = “/pci@1f,2000/pci@2” unit-address = “3,1” ipg1=20 ipg2=10;
3. Save the qfe.conf file.
4. Save and close all files and programs, and exit the windowing system.
5. Halt and reboot the system by typing the init 6 command at the superuser prompt.

APPENDIX
D
Running Diagnostics Tests
This appendix describes how to test the Sun Quad FastEthernet PCI adapter with its
FCode PROM selftest.
Note – To test the Sun Quad FastEthernet PCI adapter further, refer to the SunVTS
User’s Guide that shipped with your operating system.
Using the OpenBoot PROM FCode Selftest
The following tests are available to help identify problems with the Sun Quad
FastEthernet PCI adapter if the system does not boot.
You can invoke the FCode selftest diagnostics by using the OpenBoot user
interface test or test-all commands. If you encounter an error while running
diagnostics, appropriate messages will be displayed. Refer to the OpenBoot 3.x
Command Reference Manual for more information on the test and test-all
commands.
The selftest exercises most functionality sub-section by sub-section and ensures
the following:
■ Isolates faulty field replaceable units (FRUs)
■ Checks, with a high confidence, that no hardware fault exists on
No Trouble Found (NTF)
■ Checks connectivity during adapter card installation
■ Verifies that all components are functional
39
▼ Running the Ethernet FCode Selftest Diagnostic
To run the ethernet diagnostics, you must first bring the system to a stop at the
OpenBoot prompt after issuing a reset. If you do not reset the system, the diagnostic
tests may cause the system to hang.
For more information about the OpenBoot commands in this section, refer to the
OpenBoot 3.x Command Reference manual.
1. Shut down the system.
Use the standard shut down procedures described in Solaris 2.x Handbook for SMCC
Peripherals.
2. At the ok prompt, set the auto-boot? configuration variable to false.
ok setenv auto-boot? false
3. Reset the system.
ok reset-all
4. Type show-devs to display the list of devices.
You should see lines in the list of devices, similar to the example below, specific to
the Sun Quad FastEthernet PCI adapter:
ok show-devs
. . .
/pci@1f,2000/pci@2/SUNW,qfe@0,1
/pci@1f,2000/pci@2/SUNW,qfe@1,1
/pci@1f,2000/pci@2/SUNW,qfe@2,1
/pci@1f,2000/pci@2/SUNW,qfe@3,1
. . .
In this example, the SUNW,qfe@x,1 entries identify the device paths to the four
Ethernet channels.
5. Type the following to put the OpenBoot PROM into diagnostic mode:
ok setenv diag-switch? true
40 Sun Quad FastEthernet PCI Adapter Installation and User’s Guide • August 1997
6. Type the following to run the selftest using the test command on one of the
adapters four Ethernet channels:
ok test <device path>
The following tests are run when the test command is executed:
■ hme register
■ MAC internal loopback
■ External loopback
■ 100 Mbps PHY loopback
■ 10 Mbps PHY loopback
If the test passes, you will see these messages:
Hme register test --- succeeded.
Internal loopback test -- succeeded
Transceiver check -- Using onboard transceiver -- Link up
passed
If the channel is not connected to a network, you will see the following error
messages:
Hme register test --- succeeded.
Internal loopback test -- succeeded
Transceiver check -- Using onboard transceiver -- Link down
Autonegotiation timeout
Check Cable or contact system administrator
Failed
selftest failed. return code = -1
Note – To test other channels of the adapter, you will need to execute the test
command separately on each channel.
7. After testing the adapter, type the following to return the OpenBoot PROM to
standard operating mode:
ok setenv diag-switch? false
Appendix D Running Diagnostics Tests 41
8. Set the auto-boot? configuration parameter to true.
ok setenv auto-boot? true
9. Reset and reboot the system.
ok reset-all
