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 adapters 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  
adapters installation and users 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 systems 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 PROMs 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 systems network  
devices and to verify the Sun FastEthernet PCI adapters installation.  
You will see the systems 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

Make a note of the Sun FastEthernet PCI adapters 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 Users 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 adapters MII interface does not support external Fiber  
Optic (FX) transceivers. However, the adapters 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 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
