iv PCI ESCON Adapter Installation Guide

Chapter 1. INTRODUCTION

The PCI ESCON Adapter from Bus-Tech, Inc. is a high performance adapter that
enables PCI-based systems to communicate with mainframe systems through direct
IBM channel attachment. The ESCON adapter acts as a control unit for Enterprise
Systems Connections (ESCON); providing high speed throughput and excellent
processing efficiencies for applications that require high-speed connectivity between
a server and a mainframe. ESCON channel compatibility is guaranteed by the use of
IBM’s ESCON chipset.

The ESCON adapter can be configured to emulate the architecture of many different
device controllers. The ESCON adapter includes an onboard Intel 960 processor.
The control unit emulations are implemented directly on the 960 processor which
allows the PCI host CPU to focus on data block transfers and not channel interrupt
processing. This efficient, interrupt driven structure is utilized to avoid the CPU
overhead incurred by traditional operating system approaches. To further enhance
processing efficiency, the on-board data buffering capability allows the ESCON
adapter to respond to channel activity even when the PCI bus is temporarily busy.
Data from the channel can be buffered into on-board memory and made available to
the PCI bus when it is available. The use of modular firmware routines allows new
implementations to be developed quickly and proficiently. Due to the modularity, the
channel and PCI interface routines can be easily modified to adapt to changing
hardware and software requirements. The ESCON adapter is designed to
accommodate standardized, mainstream channel applications as well as non-standard
applications that use proprietary data transfer protocols.

Server Software

The PCI ESCON Adapter has been designed to support a wide variety of software
operating environments and communications gateways. Software currently offered
and /or supported by Bus-Tech for use with the PCI ESCON Adapter includes:

- Microsoft’s Host Integration Server (Windows 2000 and Windows NT)

- Microsoft’s SNA Server for Windows NT (Windows 2000 and Windows NT)

- IBM’s Communications Server for Windows 2000 and Windows NT

- Bus-Tech’s TCP/IP Passthrough for Windows NT

- Bus-Tech’s MPC+ for Windows (Windows 2000 and Windows NT)

Introduction 1

Additionally, the PCI ESCON Adapter includes TCP/IP Direct Connect for the
Windows 2000 and NT environments. Direct Connect provides a high-performance,
point-to-point TCP/IP connections between the mainframe and the server’s TCP/IP
stack and can be used with Bus-Tech’s MPC+ for Windows NT to provide High­Speed Data Access Services (HSAS) and MPC Point-to-Point (MPCPTP)
connections.

Introduction 3

Chapter 2. HARDWARE INSTALLATION

Installing the Adapter

CAUTION! The PCI ESCON Adapter is a PC adapter card and as such can be damaged by

Electrostatic Discharge. Before removing the adapter from it’s protective static
bag, please ensure that you are free of static charge. At minimum, you should
ground yourself to the system you are using.

The PCI ESCON Adapter is a full size PCI adapter measuring 12.283 X 4.2 inches,
Figure 2-1. The adapter hardware comes pre-configured and is ready to be installed.
There are no jumpers or switches that need setting prior to installation.

Installation procedures of the physical adapter vary depending on hardware platform
manufacturer, but have some commonalties among vendors. These steps should
guide you through a successful installation of the ESCON adapter.

Step

1. Ensure the PCI system is powered down. The ultimate assurance of this fact is to
remove the power cable from the rear of the system, where possible.

2. Remove the system cover as outlined by the system hardware manufacturer,
generally by removing the cover screws and sliding off the cover to expose the
interior of the system.

3. Determine an available slot for installation of t he adapter. The adapter requires a
full-length PCI slot. Often systems will have PCI slots which will not support full
length adapters because of processor placement. This is especially true of systems
with processor heat sinks or fans. You may have to move adapters already
installed in order to make a full length slot open for ESCON adapter.

4. Remove the adapter from its protective anti-static bag and insert the adapter into
the chosen PCI bus slot. Make sure the adapter is fully inserted in the slot. Place
a screw through the top of the mounting bracket and securely fasten to the system
chassis.

5. Replace the system cover.

6. As shown in Figure 2-1, the adapter has two connectors at the card edge; a standard
ESCON connector(top) and a serial port (bottom). Plug the IBM-compatible
ESCON channel cable directly into the ESCON connector. Ensure the cable end is
fully inserted into the socket. You should hear a click as the connector locks into
place. The serial port is for diagnostics and is not used during normal operation.

7. Reinstall the power cable, if removed in step 1, and power on the system.
If your system does not boot successfully or does not power on, ensure that you

have followed these steps or refer to the appropriate manuals for your particular
system referring to adapter installation and power up related troubleshooting.

Chapter 3. DRIVER INSTALLATION

The PCI ESCON Adapter offers drivers for Microsoft's Windows 2000 Server and
Microsoft Windows NT Server. This chapter discusses installation of the drivers.
Please refer to the section appropriate to your operating environment.

Windows 2000

Note: Bus-Tech adapters include drivers for both Windows 2000 and Windows NT.
These drivers are different and can only be installed in the appropriate
environment.

Windows 2000 Server will automatically detect Bus-Tech’s PCI ESCON Adapter the
first time your server is powered on after installing the adapter. Once detecting the
new adapter, Windows 2000 automatically invokes the New Hardware Wizard in
attempt to install drivers for the adapter.

Follow the Wizard’s installation steps, directing it to search for a suitable driver
(Figure 3-1).

Figure 3-1. Microsoft’s Hardware Installation Wizard

Insert the Windows 2000 PBSA driver diskette into your server’s diskette drive.
Then instruct the Wizard to search the system’s floppy (Figure 3-2).

Driver Installation 7

Figure 3-2. Search the Floppy

The hardware wizard will search the Windows directory and then the floppy disk.
When it finds the PBSA drivers it will prompt you for approval to install (Figure 3-3).

Figure 3-3. Confirm PBSA Driver Install

Windows 2000 will install the new drivers. At the end of installation you will be
prompted by a screen indication the New Found Hardware Wizard is completing
(Figure 3-4). Click Finish.

Windows NT

The PBSA network driver is always required in order to allow Windows NT to
communicate with the adapter. The driver must be installed once for each PCI
ESCON Adapter installed in the system. The following step-by-step procedure will
install the driver into your Windows NT Server.

Step

1. From the Windows NT Server Control Panel, open Network (Figure 3-5).
