SCSI Cabling
You can daisy chain up to 15 devices on the SunSwift SBus Adapter as follows:
Wide-to-wide devicesUse a 68-pin to 68-pin cable.
Always put wide SCSI devices closest to the host system.
Wide-to-narrow devicesUse a 68-pin to 50-pin cable.
You can include only one wide-to-narrow cable along a
chain of peripherals.
Always put the narrow SCSI devices at the end of the
chain.
The SCSI bus must be terminated at the end of the chain.
Note – If you use the SunSwift SBus Adapter for SCSI purposes only, you must
change the device name from SUNW,hme to SUNW,hme_idle to avoid a “Link
Down — cable problem?” message. Refer to SMCC Open Issues Supplement
Solaris 2.5 for more detailed information.
An additional Ethernet cable is required if you want to use your system’s
existing Ethernet interface and the SunSwift SBus Adapter Ethernet interface.
Disabling YourCurrentEthernet Device
If you remove your system’s existing Ethernet cable (either from its on-board
Ethernet device or from an existing Ethernet card) and insert it into the
SunSwift SBus Adapter Ethernet connection, you must disable your current
card’s Ethernet device. For example, if your current Ethernet device is called
le0, you would remove its IP address and host name from the /etc/hosts
file and remove the /etc/hostname.le0 file itself.
1.2If Solaris2.5 is Not Installedon YourSystem
1. Install the SunSwift SBus Adapter as described in Chapter 2 first.
2. Install the Solaris 2.5 software environment after the adapter installation,
as described in Section 2.4, “Installing the Solaris 2.5 Software.”

specific to the SunSwift SBus Adapter:
ok show-devs
...
/iommu@f,e0000000/sbus@f,e0001000/SUNW,fas@0,8800000
/iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@0,8c00000
...
• fas@0 identifies the adapter’s SCSI-2 device.
• hme@0 identifies the adapter’s Ethernet device.
Note – In the above example, the number 0 following fas@ and hme@
corresponds to the instance number of the SunSwift SBus Adapter installation.
The numbers you see when listing the system devices may be different.
If you do not see these devices listed, check that the adapter is properly seated
and reinstall the adapter, if necessary.
Refer to the Solaris 2.5 Handbook for SMCC Peripherals manual for detailed
instructions for the following tasks.
• To boot the system from the default boot device, use the boot -r command.
• To use the SunSwift SBus Adapter Ethernet interface as the boot device,
Note – A“SUNW,hme0: Link Down - cable problem?” message means that the
Ethernet cable is disconnected either at the RJ-45 connector or at the hub.

2.4Installing theSolaris 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 SUNWhmd and SUNWhmdu
packages.
The installation process will also create the necessary
/etc/hostname.hme<num> file and the hme channel entries in the
/etc/hosts file, 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 interface’s device name in the /etc/hosts file
and create its hostname.xx<num> file. Perform the following tasks after
installing the Solaris 2.5 software.
1. As superuser, edit the /etc/hosts file 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.
• hostname is literal. Type hostname.
•
num
is the instance number of the SBus card installation. Use 0 for the first
SBus card installation, 1 for 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.
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 User’s Guide document for diagnostic tests for the
SunSwift SBus Adapter.
Installing the Adapter2-5
2
2.5.3 Auto-Negotiation
A key feature of the SunSwift SBus Adapter is auto-negotiation. The autonegotiation 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 hme device driver operates the SUNW,hme device by default in halfduplex 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 hme device driver and autonegotiation. (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 hme device driver, which is loaded from the Solaris 2.5 CD-ROM, controls
the SUNW,hme Ethernet device. The device driver automatically selects the link
speed using the auto-negotiation protocol with the link partner.
You can manually configure the hme device driver parameters to customize
each SUNW,hme device in your system in one of three ways:
• Configure the hme driver parameters generally for all 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 hme.conf file in the
/kernel/drv directory.
• Use the ndd utility to temporarily change a parameter. This change is lost
