Sun FastEthernet PCI Adapter
Product Note
This document contains the late-breaking news and documentation updates for the
Sun™ FastEthernet™ PCI adapter.
Replacing a SunSwift PCI Adapter With
a Sun FastEthernet PCI Adapter in the
Same PCI Slot
Your system will encounter network problems if you replace a SunSwift™ PCI
adapter with a Sun FastEthernet PCI adapter, or if you replace a Sun FastEthernet
PCI adapter with a SunSwift PCI adapter, in the same PCI slot. To avoid these
problems, you must rename the /etc/hostname.hme<num> file on your system to
reflect the new adapter’s Ethernet interface. The /etc/path_to_instfile will be
updated when you perform a reconfiguration boot on your system after installing
the new PCI adapter.
■ If you are replacing a SunSwift PCI adapter with a Sun FastEthernet PCI adapter,
see page 2.
■ If you are replacing a Sun FastEthernet PCI adapter with a SunSwift PCI adapter,
see page 4.
Note – If you are adding a new adapter into a different PCI slot, refer to the
adapter’s installation and user’s Guide for instructions on how to install the adapter
and configure the software.

▼ To Replace the SunSwift PCI Adapter With a
Sun FastEthernet PCI Adapter in the Same PCI
Slot
Note – Refer to your system’s installation or service manual for detailed
instructions for the following three steps.
1. Power off your system and open the system unit.
2. Replace the SunSwift PCI adapter with the Sun FastEthernet PCI adapter.
3. Close the system unit.
4. Power on the system, and when the OpenBoot PROM’s banner is displayed, press
the Stop-A keys to interrupt the boot process and to display the okprompt.
5. At the okprompt, use the show-netscommand to list the system’s network
devices and to verify the Sun FastEthernet PCI adapter’s installation.
You will see the system’s network devices, which should be similar to the example
below.
ok show-nets
a) /pci@1f,4000/SUNW,hme@2,1
b) /pci@1f,4000/network@1,1
q) NO SELECTION
Enter Selection, q to quit: q
ok
■ hmeidentifies the Sun FastEthernet PCI adapter’s Ethernet device
■ networkidentifies the on-board Ethernet Device
Make a note of the Sun FastEthernet PCI adapter’s hmepathname for future
reference.
Note – If these devices are not listed, check that the adapter is properly seated and
reinstall the adapter, if necessary.

6. Perform a reconfiguration boot on your system.
ok boot -r
After rebooting your system, login as super-user (root).
7. At the command line, use the grepcommand to search the /etc/path_to_inst
file for hmedevices.
# grep hme /etc/path_to_inst
"/pci@1f,4000/network@1,1" 0 "hme"
"/pci@1f,4000/pci@2/SUNW,hme@0,1" 1 "hme"
"/pci@1f,4000/SUNW,hme@2,1" 2 "hme"
(On-board hmeinterface)
(SunSwift PCI hmeinterface)
(Sun FastEthernet PCI hmeinterface)
In the example above, the network@1,1instance is the on-board FastEthernet
device, the old SUNW,hme@0,1instance is for the previous SunSwift PCI adapter,
and the new SUNW,hme@2,1instance is for the Sun FastEthernet PCI adapter.
You will need to know the instance number for Sun FastEthernet PCI adapter. In the
above example, the instance number for the Sun FastEthernet PCI adapter is 2,
which is shown in bold.
8. Using the instance number found in Step 7, rename the
/etc/hostname.hme<num> file previously used by the SunSwift PCI adapter to
reflect the new instance number used by the Sun FastEthernet PCI adapter.
For example, if the previous file had an *.hme1extension, and the new instance
number is 2, you would type:
# mv /etc/hostname.hme1 /etc/hostname.hme2
9. Halt and reboot your system.
# init 6
Note – Refer to the Sun FastEthernet PCI Adapter Installation and User’s Guide for
more information about configuring the driver software.

Using the testnetCommand on an
Adapter With an External Transceiver
If your adapter is connected to an external transceiver, you will see incorrect error
messages when using the OpenBoot PROM (OBP) testnetcommand. Although
the testnetcommand will pass the first time it is used, it will fail on subsequent
tests, even though the Ethernet interface is functional and can be used.
You can avoid seeing these false test failures by using the OBP reset-all
command between testing the adapter with testnetcommand. Refer to bug id.
4062368 for more information.
Note – Refer to the OpenBoot 3.x Command Reference Manual (part number:
802-5837-xx) for more information about the testnetand reset-allcommands.
This document can be found in the Solaris 2.6 Answerbook.
Known Problems
The following sections list the known problems and workarounds if they exist.
Fiber Optic Transceivers
The Sun FastEthernet PCI adapter’s MII interface does not support external Fiber
Optic (FX) transceivers. However, the adapter’s MII interface does support TX, T4,
and AUI external transceivers that comply with the IEEE 802.3u standard.
Refer to bug id. 4062714 for more information.
FastEthernet Switches (100BASET)
There are two FastEthernet (100BASET) switches which currently do not operate
with the Sun FastEthernet PCI adapter:
■ Bay Networks Model 28115
■ Fore Systems (all models)

Autonegotiation
Autonegotiation is broken (10Mbps) in the hmedriver.
Refer to bug id. 4064879 for more information.
Patch 104212-06 fixes bug 4064879.
Ultra 170E
In the Ultra 170E, an MII-AUI transceiver hangs the network in 10Base-T mode.
Refer to bug id. 1252776 for more information.
Patch 10412-04 fixes bug 1252776 and resolves the problems with MII-AUI
transceivers in full-duplex mode on dumb 10Base-T hubs.
