Hardware Installation  
This chapter describes how to install the ITI-5232E adapter in your PCI based bus master compatible  
computer, and how to connect it to your network.  
The ITI-5232E host adapter is Plug and Play on the host systems PCI bus, and no configuration of  
the adapter hardware is necessary.  
System Requirements  
Before you begin the installation procedure, you will need:  
An available PCI bus master expansion slot  
A system that is compatible with the PCI Specification, Version 2.1  
A floppy disk drive for loading the software drivers  
UTP category 3,4 or 5 cable (type dependant on your network type)  
For multi-channel adapters such as the ITI-5232E it is required that your host system  
firmware or BIOS support PCI bridging. If your host does not support PCI bridging contact  
your system vendor for a BIOS upgrade. If your system can not be brought into compliance  
with the PCI bridge specification, then you will not be able to use multi-channel ITIpci host  
adapters.  
Installing the adapter  
The following procedure should be used to install the ITI-5332E adapter:  
1. Turn OFF the power to the computer system, and to all peripherals directly connected to  
the system (monitor, printer, external SCSI enclosures, etc.)  
2. Unplug the system from the AC power line  
3. Use an anti-static strap or precautions to avoid static discharge to your computer system  
or the ITI-5232E adapter  
4. Remove the access cover from your system (refer to the system’s documentation)

Digital UNIX  
Drivers for the ITI-5232E are on the Digital UNIX distribution kit beginning with  
Version 4.0D. Digital UNIX will identify the ITI-5232E as four 21140 based Ethernet  
controllers.  
Once the hardware is installed in your system, boot the system using genvmunix, in the  
following manner:  
>>>boot –file genvmunix  
This will cause Digital UNIX to scan all hardware devices in the system, and identify the  
ITI-5232E . Four 21140 based Ethernet adapters will be identified.  
Create a new kernel with support for the four Ethernet ports, identified in genvmunix by  
using the doconfig command.  
# doconfig  
When doconfig completes backup your existing kernel as follows:  
# cp /vmunix /vmunix.sav  
Then copy the new kernel created by doconfig, to /vmunix, and shutdown and reboot with  
your new kernel.  
If you are unfamiliar with doconfig, refer to your Digital UNIX documentation for  
additional information.  
Note: Digital UNIX relies on the settings for media type and speed set by the SRM console.  
See Appendix A for more information.

Digital OpenVMS  
Drivers for the ITI-5232E are on the Digital OpenVMS distribution kit beginning with  
Version 7.1. Digital OpenVMS will identify the ITI-5232E as four 21140 based adapters.  
Follow the documentation for the network software you will be running on the adapter for  
specific configuration information.  
Note: Digital OpenVMS relies on the settings for media type and speed set by the SRM  
console. See Appendix A for more information.  
Note: If you are connecting “Point to Point” to another adapter, do not select Auto-Sense  
for ewa0_mode. Also, many hubs do not support Auto-Sense, it is therefore recommended  
that the correct media type and speed are selected manually.

Appendix A  
Digital’s SRM Console Settings  
When the ITI-5232E is being used in a Digital Alpha platform running OpenVMS or  
Digital UNIX, the SRM console is used to set the port speed, media (cable) type and boot  
protocols, and can also be used to test the module.  
After powering your system up, and before booting your operating system, the system  
will stop at the SRM console prompt. On a uni-processor machine, the SRM prompt is  
“>>>” and on the primary processor of a multi-processor machine, is “P0>>>”.  
Digital uses a set of “Environment Variables” to store the settings of certain user  
definable parameters, which are passed to the operating system to allow the users  
configuration information to stay consistent when the SRM passes control of the system  
to the operating system.  
Displaying and Setting Ethernet Port Characteristics  
The Alpha console recognizes the Ethernet device as an EW port. There are two  
commands that are necessary for setting and showing the Ethernet port:  
SET and SHOW.  
Use SHOW to display characteristics of the Ethernet port.  
>>>Show EWn0_MODE  
Where ‘n’ is the Ethernet port letter.  
Use SET to set characteristics of the Ethernet port. The available settings for  
Ethernet media type are shown in Table 4.

For example, to set the media type and speed to FAST Twisted Pair, enter the  
command:  
>>>set ewa0_mode FAST  
If you will be remote booting via the Ethernet, you must also set the boot protocol  
to match that of the boot node. Typically OpenVMS uses MOP protocol and UNIX  
uses BOOTP.  
For example to set a port to MOP (VMS) use:  
>>>set ewa0_protocol MOP  
Note: Port 0 will be the lowest controller letter found by the SRM console, “A” if there are  
no other Ethernet ports in the system. If there is an onboard Ethernet controller, it will be  
assigned port letter “A” and the ports on your ITI-5232 will be assigned “B,C,D and E” for  
ports “0,1,2 and 3” respectively.

Table 7 Adapter to Adapter (point to point) Wiring  
Cabling Requirements  
In order for your network to operate properly, you must use a category of network cabling  
that is appropriate for the data rate of the channel. For 10Mb/s operation, Category 3, 4  
or 5 cable is appropriate. When operating in 100Mb/s or 100Mb/s Full Duplex, a  
Category 5 cable should be used.  
The maximum cable segment length supported at 100Mb/sec speed, on Category 5 cable  
is 100M. Any single cable segment (adapter to adapter or adapter to network hub) must  
be within the 100M length requirement.

Appendix C:  
Troubleshooting  
Windows NT Version 4.0 and 3.51  
The most common problem encountered on Windows NT for Ethernet devices is a  
mismatch of the port’s speed and media settings to those in use on the network. The most  
simple check of correct cabling is to observe the status lights on the handle of the card.  
Once the card is installed in the system, the software is installed, and the module is wired  
to your network hub, the LINK light should be illuminated. If LINK fails to light, check  
that your cable type and media settings are correct. Appendix B provides cable  
information for all configurations.  
If you are connected to a FAST hub, be sure card is set to AUTO1, FAST or FAST Full  
Duplex, depending on the capability of your hub.  
If you are connected to a 10Mb/sec hub, the card should be set to AUTO1, Twisted Pair or  
Twisted Pair Full Duplex, depending on the capability of your hub.  
Cables from the ITI-5232E to a hub MUST NOT BE CROSSOVER.  
Cables from the ITI-5232E to another ITI-5232E MUST BE CROSSOVER.

TIP: If you are certain your cable type is correct, but you are not seeing LINK, setting the  
port to match the hub port exactly (ex. FAST, not AUTO). Some hubs have trouble with  
cards set to AUTO negotiate.  
Error messages  
The error messages are logged in the Windows NT Error Log and can be seen using the  
Error Log Viewer (in NT's Administration Tools group).  
Each error message has a standard NDIS error code and a driver's additional code. The  
additional codes are listed in Table 8.
