TURBOWAYS 25 ATM MicroChannel Adapter Figure 2-2. Inserting the Adapter into the Socket Figure 2-3. Connecting the UTP/STP Cable to the ATM Switch Box 2 Installing the TURBOWAYS 25 ATM MCA Adapter This chapter explains how to install the TURBOWAYS 25 ATM MCA adapter into an MCA computer, how to configure the computer to use the adapter, and how to connect ATM cables. Installing the Adapter Note: Do not install more than one adapter in a computer. To install the adapter in a computer 1 Turn off the computer and any attached devices, and disconnect all power cords. 2 Detach all cables from the back of the computer. 3 Remove the cover from the computer case. (Refer to the computer user documentation for instructions.) Attention: To avoid possible damage to the adapter or any computer components, touch the metal part of the computer's power supply to discharge any static electricity in your clothes and body. (Use a wrist grounding strap if you have one.) 4 Locate an available 32-bit MCA expansion slot in the computer, and remove the slot cover. Store the slot cover in a safe place in case you need to use it again. 5 Carefully remove the TURBOWAYS 25 ATM MCA adapter, which is illustrated in Figure 2-1, from its antistatic packaging. Hold the adapter by its edges to avoid touching the components or the connectors. 6 Align the adapter with the MCA expansion slot, and insert the adapter firmly into the socket, as shown in Figure 2-2. 7 Attach the adapter bracket to the computer chassis. 8 Reassemble the computer, and replace the cover on the computer case. (Refer to the computer user documentation for instructions.) Configuring the MCA Computer Once you have installed the adapter into the computer, you must configure the computer to use the adapter. Note: The MicroChannel Configuration program (Reference diskette) has been implemented differently on various computer models. Follow the instructions in the computer user documentation for installing a feature card or an option. Configuring the Computer Following is the general procedure for configuring an MCA computer. (Refer to the computer user documentation for specific instructions.) 1 Install the hardware. 2 Boot into the Reference diskette or partition environment. 3 Run Automatic Configuration; the computer might automatically do this for you. 4 When you are prompted to copy or insert an option diskette, insert the ATM25 MicroChannel Adapter Option Diskette in drive A. 5 Remove the diskette from drive A, and reboot the computer. Changing Automatically Configured Parameters To change the automatically configured parameters 1 Boot into the Reference diskette or partition environment. 2 On the Main Menu, select Set Configuration and press Enter. 3 On the Set Configuration window, select Change Configuration and press Enter. 4 Using the ] and  keys, scroll through the configuration parameters to find the section labeled ATM25 NIC. 5 Change the parameters in the ATM25 NIC adapter section as follows: a Use the ] and  keys to select parameters. b Press F5 or F6 to select a setting for each parameter. Table 2-1 lists and describes the ATM25 NIC parameters in the Change Configuration screen. Note: If the selected setting is preceded by an asterisk (*), that setting (or value) is being used by another device and cannot be used by the adapter. Table 2-1. Automatically Configured Parameters Parameter Field Description Arbitration Level The priority level assigned to the adapter. The arbitration procedure provides functions to resolve multiple requests for control of the bus. An adapter capable of becoming a bus master can be assigned this value. The highest priority, 0, is used for adapters with low latency. The lowest priority, 15, is used by the system master and is reserved. Adapter I/O Port Address The I/O port address used by the adapter to communicate with the CPU. This address must be unique from that used by another device. Select Interrupt Line The level-triggered interrupt used by the adapter. This interrupt must be different from those used by other devices in the system. Streaming Data Provides performance improvements over basic data transfer. When Streaming Data is set to Enable, the adapter can transfer data at a peak rate of 40 MBytes/sec. When Streaming Data is set to Disable, the peak transfer rate is 20 MBytes/sec. This parameter must be disabled for older PCs that do not support data streaming (namely 386 and some older 486 PCs). Streaming Data should be set to Enable for PCs that support data streaming. Fairness Enable Forces a bursting adapter to equitably share the bus with other adapters. When Fairness Enable is set to Disable, any bus master adapter uses the bus as long as it needs the bus or until another master requests the bus. Then the adapter gives up the bus and requests the bus again immediately. When Fairness Enable is set to Enable, the adapter waits until all other bus masters have finished using the bus before making another request to use the bus. This parameter should be set to Enable. Base Memory Address The memory address where the adapter memory starts. The default ATM adapter base memory address is FF800000h (hex), which is the top of the 32-bit address space. The adapter uses 4 MBytes of virtual memory (not physical memory). 6 When you have made all changes, save the changes and reboot the computer according to the instructions in the computer user documentation. Connecting the TURBOWAYS 25 ATM MCA Adapter to the Network Before you can use the TURBOWAYS 25 ATM MCA adapter, you must connect it to an ATM switch or concentrator. Do not set up two computers back-to-back, that is, without a switch. This is not supported by the ATM software. Note: The RJ-45 connector pinout on the adapter conforms with the ATM Forum standard. If the switch connector pinout is not compatible with this standard, obtain or create a cable to convert to the required pinout. (See RJ-45 Receptacle Pin Assignment on page B-4 for pinouts.) To connect the TURBOWAYS 25 ATM MCA adapter to an ATM switch or concentrator 1 Obtain connecting cable. (See Appendix B, Product Features and Specifications, for cable specifications and part numbers.) 2 Connect one end of the cable to the adapter. 3 Connect the other end of the cable to the wall outlet or directly to the ATM switch or concentrator, as in Figure 2-3. Contact your system administrator for assistance. Note: Because the adapter uses only Switched Virtual Circuits (SVCs), make sure the switch is configured to SVCs. (Refer to the switch documentation for details.) r 3 Installing and Using ATM Software for OS/2 with LAPS This chapter contains instructions for installing, using, configuring, and removing the ATM software and for configuring ATM workstations running OS/2 with LAN Adapter and Protocol Support (LAPS). If you are using Multi-Protocol Transport Services (MPTS), go to Chapter 4. Determining Your ATM Needs Before you install ATM drivers, you must determine if you should use Classical Internet Protocol (CIP) or LAN Emulation (LANE). You cannot install and operate both CIP and LANE drivers at the same time. If you are using only TCP/IP for your network protocol and you will not have any bridges in the network, use Classical IP for optimal performance. If you are using any upper-level protocols with bridges, use LAN Emulation. Installing and Using Classical IP Drivers Note: Do not install the ATM software unless you have installed the TURBOWAYS 25 ATM MCA adapter in the computer, as explained in Chapter 2. Install only one driver 4 the ATM client driver, the ATM Address Resolution Protocol (ARP) server and client driver, or the LANE driver 4 and do not install a driver more than one time. No more than one driver or one instance of the driver is supported in the system. If you need to reinstall a driver or install an updated driver, remove the old driver first, as explained in Removing ATM Drivers on page 3-16. Locating ATM Files and Directories Table 3-1 lists the files that are copied onto the hard drive from the OS/2 Classical IP Device Driver diskette when you install the ATM Classical IP software. The specific files that are installed on the hard drive depend on the driver you choose to install. The diagnostics utility, aatmdiag.exe, is not copied onto the hard drive during installation. Table 3-1. Location of Classical IP ATM Files After Installation Default Directory Driver Description \ibmcom\macs os2arp25.os2 os2arp25.nif ATM ARP server and client driver ATM ARP driver installation file os2atm25.os2 os2atm25.nif ATM client driver for the adapter ATM driver installation file \ibmcom atmh.msg atm.msg lantran.log Message file used at the command line with boot error numbers Message file with boot messages Log file of driver actions Note: If the OS/2 Classical IP Device Driver diskette contains a readme file, be sure to read the file before installing the ATM CIP software. Using Classical IP To use CIP over TCP/IP, a Logical IP Subnetwork (LIS) must be set up, and one station must be configured as an ATM ARP server. The computer with the adapter is capable of being the ARP server for one LIS. The computer may function as both an ARP server and a client. The following tables show the trade-off between the possible number of simultaneous ATM ARP connections and ATM client connections. Table 3-2 lists the number of connections when ATM extended on-board buffering is disabled. Table 3-3 lists the number of connections when ATM extended on-board buffering is enabled. In both tables, it is assumed that the maximum frame size is 9180. (The ATM extended on-board buffering parameter is explained on page 3-8 of Table 3-4.) Table 3-2. ATM ARP vs. ATM Client Connections (ATM Extended On-board Buffering Disabled) ATM ARP Connections ATM Client Connections 400 0 350 5 250 10 125 18 0 26 Table 3-3. ATM ARP vs. ATM Client Connections (ATM Extended On-board Buffering Enabled) ATM ARP Connections ATM Client Connections 400 0 350 2 to 3 250 5 125 9 0 13 You need to decide which driver to install. If your computer is to be the ARP server for your LIS, install the ATM ARP server and client driver (os2arp25.os2). If your computer is to be a client only, then install the ATM client driver (os2atm25.o2s). Installing ATM CIP Drivers This section describes how to install both the ATM CIP client driver and the ATM CIP ARP server and client driver package. To install the ATM CIP drivers 1 Open the LAPS icon, or type the following command from an OS/2 Window and press Enter: \ibmcom\laps 2 On the IBM LAN Adapter and Protocol Support window, select Install. 3 Insert the OS/2 Classical IP Device Driver diskette in a diskette drive. 4 On the Install Additional Network Drivers window a If you are installing the ATM client driver, in the Source field, type the drive letter of the diskette drive that contains the OS/2 Classical IP Device Driver diskette, and select OK. b If you are installing the ATM ARP server and client driver, type the drive letter and the directory name in the Source field, and select OK. For example a:\arpserv.os2 where a: is the letter of the diskette drive that contains the OS/2 Classical IP Device Driver diskette and \arpserv.os2 is the directory that contains the driver files. 5 When the Installation Complete message appears, select OK. Note: If an error message appears, some version of the driver might already be installed in the computer. Select Cancel on the error message window; remove the driver, as explained in Removing ATM Drivers on page 3-16; and go back to step 1. 6 Remove the OS/2 Classical IP Device Driver diskette from the diskette drive. 7 On the IBM LAN Adapter and Protocol Support window, select Configure. 8 On the Configuration window, select Configure LAN transports, and then select Continue. 9 On the Configure Workstation window, select the driver you installed in step 4 from the Network Adapters list, and then select Add: n 25 Mbps ATM MCA Adapter (Client Only) for the ATM client driver or n 25 Mbps ATM MCA Adapter (ARP Server and Client) for the ATM ARP server and client driver 10 On the Configure Workstation window, select IBM TCP/IP from the Protocols list, and then select Add. 11 Write down the LAN interface number to the left of IBM TCP/IP in the Current Configuration list. For example, you would write down LAN Interface 1 for the following entry: 1 - IBM TCP/IP You will need this number to configure TCP/IP. (See Using TCP/IP on page 3-15.) 12 On the Configure Workstation window, double-click on one of the following drivers in the Current Configuration list: n 25 Mbps ATM MCA Adapter (Client Only) for the ATM client driver or n 25 Mbps ATM MCA Adapter (ARP Server and Client) for the ATM ARP server and client driver 13 On the 25 Mbps ATM MCA Adapter (ARP Server and Client)/(Client Only) window, edit the parameters by typing a setting/value in the field provided for each parameter. (Settings/values and settings that initially appear in the fields are the defaults.) Use the ] and  keys to move among parameters. For each configurable parameter, select Range to display the range available, or select the field and press F1 for help. Table 3-4 lists and describes the 25 Mbps MCA ATM Adapter (ARP Server and Client)/(Client Only) window parameters: Table 3-4. 25 Mbps ATM MCA Adapter (ARP Server and Client)/ (Client Only) Window Parameters Parameter Field Description ARP Server ATM Address The 20-byte address of the ATM ARP server. This parameter is required for the CIP client. You must use exactly 40 hex characters: the first 13 bytes are the switch address; the next 6 bytes are the MAC address of the ARP server; and the last byte is the selector used for the ARP server. Each byte must be represented by exactly 2 digits, e.g., 0 = 00, C = 0C, etc. If you leave this field blank, the driver assumes its own ATM address. IP Address The IP address of this workstation for the ATM adapter. You may use a maximum of 15 characters in dotted decimal format (e.g., 162.62.51.50). Write this address down; you'll use it when you configure TCP/IP. (See Using TCP/IP on page 3-15.) ARP Server IP Address The IP address of the ARP server. The ARP Server IP address is used only for ATM ARP purposes and will reject any IP traffic. You may use a maximum of 15 characters in dotted decimal format (e.g., 162.62.43.254).

TURBOWAYS 25 ATM MCA Adapter) B Product Features and Specifications This chapter provides an overview of TURBOWAYS 25 ATM MCA adapter features. This chapter also includes a list of product specifications. Features The TURBOWAYS 25 ATM MicroChannel Adapter is an ATM Network Interface Card (NIC) designed to be easily installed in an MCA slot of a computer. The adapter is specifically designed to enhance the computer's performance by providing easy access to ATM networks. The adapter supports an RJ-45 shielded connector, which connects easily to either a UTP 3 or better or Type 1 STP copper cable. The maximum cable length between the adapter and the switch connector is 100 meters. The adapter delivers high performance in terms of low latency, high throughput, and fast response time. The adapter supports simultaneous inbound and outbound transfers at the maximum line speed. At the physical layer, the adapter conforms to the ATM Forum's standard pinouts and 25.6 Mbit/sec standard transmission method. The TURBOWAYS 25 ATM MCA adapter is illustrated in Figure 4-1. One of the adapter's most important functions is to perform the segmentation and reassembly of data for communication with the ATM network. The adapter segments outgoing PDUs into ATM cells and transmits them on to an ATM network for delivery to the destination. The adapter uses AAL 5 protocol to map PDUs into the information field of the ATM cell. The adapter also reassembles incoming cells into a larger AAL-5 frame and uses a buffering system scheme for the efficient transfer of PDUs between the adapter and the host computer. The following list summarizes of the features of the TURBOWAYS 25 ATM MCA adapter: n 32-bit MCA bus master n Supports data streaming n Direct memory access (DMA) n 512 KBytes of packet memory n Dedicated 25 Mbit/sec full-duplex connection n SVC support n ATM adaptation layer (AAL) 5 support n ATM user network interface (UNI 3.0 or 3.1) featuring C Scalability for present and future network requirements C Bandwidth on demand C Aggregation of voice, data, and video traffic into one transmission scheme Specifications The adapter complies with applicable ATM Forum specifications and with MCA bus specifications.

A Address Resolution Protocol (ARP) A protocol that dynamically maps between Internet addresses, baseband adapter addresses, X.25 addresses, and token-ring adapter addresses on a local area network. American National Standards Institute (ANSI) The coordinating body for voluntary standards groups within the United States. ANSI is a member of the International Organization for Standardization (ISO). Asynchronous Transfer Mode (ATM) A form of data transmission based on fixed-length packets, called cells, that can carry data, voice, and video at high speeds. This technology is designed to combine the benefits of switching technology (constant transmission delay, guaranteed capacity) with those of packet switching (flexibility, efficiency for intermittent traffic). ATM is defined by ITU-T specifications. ATM Adaptation Layer (AAL) One of the three layers of the ATM protocol reference model. It translates incoming data into ATM cell payloads and translates outgoing cells into a format readable by the higher layers. Five AALs have been defined: AAL1 and 2 handle traffic like voice and video which is sensitive to transmission delays, while AAL 3, 4, and 5 pertain to data communications through the segmentation and reassembly of packets. ATM Layer A service independent layer that sits on top of the PHY Layer. The ATM layer receives the 48-byte SAR- PDU from the AAL Layer, adds the 5-byte header, then transfers this 53-byte ATM cell to the PHY Layer. Two different formats are used to create the ATM cell4one for the UNI and one for the NNI. The UNI and NNI cell headers are exactly the same except that the UNI replaces the first 4 bits of the VPI field with a GFC field, which is not used at this time. ATM Switches ATM switches are the heart of ATM technology. ATM switches initially set up the virtual circuit for the end nodes to communicate. Then they route the incoming ATM cells using the VPI/VCI numbers to the appropriate outgoing VPI/VCI and on to the respective node. ATM switches are currently designed with one of two hardware standards: the ATM backplane and the ATM matrix. B Best Effort The transmission is sent using the highest bandwidth available to the driver. If you do not select Best Effort, your data is sent when all of the specified requirements have been met. C cell The fixed-length transmission unit used by ATM. Each cell is 53 bytes long with a 5-byte header containing its connection identifier and a 48-byte payload. See CLP, HEC, PTI, and VCI/VPI. cell-switching A technology used by ATM to combine circuit-switching and packet-switching, for a fast and inexpensive way of transmitting various kinds of data. channel A path along which signals can be sent, for example, data channel, output channel. (A) circuit-switching A communication technology that is appropriate for constant bit rate services such as voice and image. It is used by ATM in combination with packet-switching. Classical IP Defined by RFC 1577. constant bit rate (CBR) Used for real time services/data transmissions that accept no or very little delay of the output signal. Video for instance is a continuous bit rate service. See Isochronous. Consultative Committee for International Telegraph and Telephone (CCITT) An international organization that develops communication standards such as Recommendation X.25. Name recently changed to ITU (International Telecommunication Union). Control Plane In the B-ISDN protocol reference model, the layer which handles signalling and connection control functions. D Double Buffer Assigned to receive VCCs on the adapter for reassembly of PDUs. Double Buffer increases the amount of buffer space allocated to a VCC, maximizing throughput while decreasing the number of available VCCs. E erasable programmable read-only memory (EPROM) An integrated circuit used to store the host adapter BIOS and firmware. EPROMs can be erased by exposure to ultraviolet light and then reprogrammed with different data. Ethernet A 10-Mbps baseband local area network that allows multiple stations to access the transmission medium at will without prior coordination, avoids contention by using carrier sense and deference, and resolves contention by collision detection and transmission. Ethernet uses carrier sense multiple access with collision detection (CSMA/CD). G gateway A functional unit that interconnects two computer networks with different network architectures. A gateway connects networks or systems of different architectures. A bridge interconnects networks or systems with the same or similar architectures. (T) H Header Error Control (HEC) The HEC field is an 8-bit CRC computed on all fields in an ATM header and capable of detecting single-bit and certain multiple-bit errors. hub In a network, a point at which circuits are either connected or switched. For example, in a star network, the hub is the central node; in a star/ring network, it is the location of wiring concentrators. I Institute of Electrical and Electronics Engineers (IEEE) A professional society accredited by the American National Standards Institute (ANSI) to issue standards for the electronics industry. Interim Local Management Interface (ILMI) The standard specification used to manage an ATM network. The ILMI uses the SNMP protocol and an ATM UNI MIB to provide the administrator with status and configuration information.
