2.4 Installing the Solaris 2.5 Software  
You will be installing software from the Solaris 2.5 CD-ROM. Make sure the  
Solaris 2.5 CD-ROM is properly placed in the CD-ROM drive before  
performing the following tasks.  
Install the Solaris 2.5 software.  
Installing the software will automatically add the SUNWhmdand SUNWhmdu  
packages.  
The installation process will also create the necessary  
/etc/hostname.hme<num> file and the hmechannel entries in the  
/etc/hostsfile, only if you select hme<num> as the primary interface when  
prompted during the installation.  
If you are going to use more than one Ethernet interface, you must manually  
re-enter your existing Ethernet interfaces device name in the /etc/hostsfile  
and create its hostname.xx<num> file. Perform the following tasks after  
installing the Solaris 2.5 software.  
1. As superuser, edit the /etc/hostsfile and add an entry for the existing  
Ethernet device, for example, le0.  
2. Create a /etc/hostname.xx<num> file for the Ethernet channel you are  
planning to use for the existing Ethernet device.  
hostnameis literal. Type hostname.  
numis the instance number of the SBus card installation. Use 0for the first  
SBus card installation, 1for the second instance, and so on.  
3. In this file, add a line containing just the host name for the existing  
Ethernet interface. For example, if your host name is zardoz, enter just  
this word.

2.5 Post-Installation Procedures (Optional)  
Perform the following tasks to verify and customize the performance of the  
SunSwift SBus Adapter.  
2.5.1 Watching Network Activity  
Make sure that you are connected to an active network.  
You can watch network activity or incoming network packets by typing  
the following:  
ok watch-net-all  
/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@0,8c00000  
hme register test -- succeeded.  
Internal loopback test -- succeeded.  
Transceiver check -- Using Onboard Transceiver, 100 Mbps Link  
Down, 10 Mbps Link Up, passed  
Using Onboard Transceiver, 100 Mbps Link Down, 10 Mbps Link Up,  
Looking for Ethernet packets.  
'.' is a good packet. 'X' is a bad packet.  
Type any key to stop.  
...........  
Note – The network speed is the same as the speed of the hub to which your  
system is connected. See Section 2.5.3 “Auto-Negotiation” and Section 2.5.4  
“Configuring Driver Parameters” for information on speed selection.  
2.5.2 Running Diagnostics  
Refer to the SunVTS 1.0 Users Guide document for diagnostic tests for the  
SunSwift SBus Adapter.  
Installing the Adapter  
2-5  
 
     
2
2.5.3 Auto-Negotiation  
A key feature of the SunSwift SBus Adapter is auto-negotiation. The auto-  
negotiation protocol, as specified by the 100BASE-TX standard, automatically  
selects the operation mode (half-duplex or full-duplex) and speed (10 Mbps or  
100 Mbps) for the adapter.  
The hmedevice driver operates the SUNW,hmedevice by default in half-  
duplex mode only.  
If the SunSwift SBus 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 SunSwift SBus 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.  
Refer to the Platform Notes: The hme Fast Ethernet Device Driver document (Part  
No: 802-3970) for more information on the hmedevice driver and auto-  
negotiation. (This document is also available on the Solaris 2.5 and the Solaris  
2.5: 1/ 96 AnswerBook.)  
2.5.4 Configuring Driver Parameters  
The hmedevice driver, which is loaded from the Solaris 2.5 CD-ROM, controls  
the SUNW,hmeEthernet device. The device driver automatically selects the link  
speed using the auto-negotiation protocol with the link partner.  
You can manually configure the hmedevice driver parameters to customize  
each SUNW,hmedevice in your system in one of three ways:  
Configure the hmedriver parameters generally for all devices in the system  
by entering the parameter variables in the /etc/systemfile.  
Set a parameter on a per-device basis by creating the hme.conffile in the  
/kernel/drvdirectory.  
Use the nddutility to temporarily change a parameter. This change is lost  
when you reboot the system.
