INTRODUCTION
TECHNICAL FEATURES
SMC's Ethernet "MC" boards, the 3016/MC and 3016TP/MC, are 16-bit, high-performance network controller boards designed to operate with the IBM Personal System/2TM and compatible Micro ChannelTM Architecture machines. These boards are suited for network file server, workstation and bridge applications.
IEEE 802.3 Compatibility
These boards comply fully with the IEEE 802.3 specifications listed in the following table:
| BOARD | SPECIFICATION |
|---|---|
| SMC3016TP/MC |
10BASE-T (Twisted Pair)
10BASE5 (Thick Ethernet) |
| SMC3016/MC |
10BASE2 (Thin Ethernet)
10BASE5 (Thick Ethernet) |
The on-board EtherStar MB86950 Controller provides full CSMA/CD (Carrier Sense/Multiple Access with Collision Detection), 10 Mbps (Megabits per second) baseband operation for both boards.
Direct 10BASE-T Connectivity for the SMC3016TP/MC Board
The 3016TP/MC features an on-board transceiver and an RJ-45 connector for direct connection to unshielded twisted pair wiring in a star topology. The central component of an Ethernet twisted pair network is a 10BASE-T wiring concentrator, such as SMC's own Ethernet 3508TP.
Direct 10BASE2 Connectivity for the SMC3016/MC Board
The SMC3016/MC features an on-board transceiver and a BNC connector. These enable the board to be connected directly to Thin Ethernet cable (RG-58A/U or RG-58C/U) with a BNC T-Connector.
TECHNICAL FEATURES
Connectivity to Other Media Via AUI Port
Connection to Thick (10BASE5) or Thin (10BASE2) Ethernet cable, or to optical fiber or twisted pair wiring, is also provided through the Attachment Unit Interface or AUI port on both boards. An external transceiver with the appropriate cable tap is required for connection to this port.
Customized Drivers
Each Ethernet "MC" board is shipped with an SMC driver diskette containing high-performance driver support for a variety of network operating systems and protocols. Also present is a copy of SMC's Adapter Descriptor File (ADF), which is required to properly configure the board's hardware options when the system is initialized.
If a supplement containing driver configuration information is enclosed, please refer to it prior to loading any software drivers. Also, follow the instructions in the README.EXE file on the diskette when loading these drivers.
Outstanding Performance
Advanced hardware features - 16-bit wide Data Bus, EtherStar Controller, 16K byte Data Packet Buffer and Dual-ported RAM - in conjunction with SMC's high-performance drivers, enable the board to achieve significant throughput, even on large or heavily loaded networks.
The EtherStar Controller provides arbitration circuitry which allows dual port access by both the station and the network. Simultaneous access by the station and the network is a highperformance feature that eliminates CPU delays. For example. the station can extract data from the receive buffer while, at the same time, the Controller is loading a packet into the receive buffer from the cable.
16K bytes of buffer memory are used for transmitting and receiving network packets. Management of the buffer is provided by the EtherStar chip. 12K bytes are used for the receive buffer. Page 4
The remaining 4K bytes are always reserved as a transmit buffer. Since the maximum packet size allowed for Ethernet is 1,526 bytes (including preamble), a 4K transmit buffer ensures at least double buffering of transmit packets. This multi-packet feature further enhances the board's performance.
Diagnostic LEDs
The SMC3016TP/MC has three green diagnostic LEDs: transmit (TX), receive (RX) and link integrity (LNK) status; and one yellow LED: collision (COL) status. The SMC3016/MC has two green diagnostic LEDs: transmit (TX) and receive (RX) status. The function of these LEDs is provided in the table below:
| BOARD | LED | ON CONTINUOUSLY |
|---|---|---|

ТХ | The board is transmitting. |
|
3016TP/MC
3016/MC |
RX | The board is receiving — even if the data is not intended for that station. |
| 3016TP/MC | LNK |
The link test pulse is good:
the board is connected, and the wiring polarity is correct. |
| 3016TP/MC | COL |
There are collisions on the line. Note
that it is normal for the yellow LED to blink. |
TECHNICAL FEATURES
Extended Distance Thin Ethernet Segments
The IEEE 802.3 10BASE2 specification defines the maximum length of a Thin Ethernet segment as 607 feet (185m). However, the SMC3016/MC supports Thin Ethernet segments of up to 1,000 feet (305m) in length with 50 ohm RG-58 cabling meeting the following specifications:
| Nominal Attenu | ation at 10MHz | |
|---|---|---|
| # of Nodes |
per 1,000 feet
(305m) |
per 100 feet
(30m) |
| Maximum 10 | 13db or less | 1.3db or less |
| Maximum 30 | 12db or less | 1.2db or less |
Configurable Hardware
The boards are equipped with one jumper and a pulse transformer. They are used to select the cable connector, and are clearly labeled on the board. Instructions for configuring the hardware is provided in this guide.
Optional Auto-Boot PROM for NetWare
A PROM socket, which can accommodate a device up to 16K by 8, is provided on the board for an optional auto-boot PROM. The PROM enables a diskless station to access the network, and also may be used as a convenience on any system with floppy and/or hard disk drives. The base address of the PROM is software-configurable.
SMC offers two 8K by 8 NetWare PROMs for this board: P/N SMC3016-NP (for IEEE 802.3 Ethernet), and P/N SMC3016-NP2 (for version 2.0 Standard Ethernet). Each PROM requires 8K bytes of PC memory address space. Once installed, the PROM can be enabled via the automatic configuration program. If the PROM is not enabled, the SMC3016TP/MC does not require any of the computer's memory address space.

TECHNICAL FEATURES
Network Address
A unique Ethernet Network Address is assigned to each Ethernet board. This network address, stored in an EEPROM on the board, is based on two component values: a unique vendor ID assigned by the IEEE, and a unique serial number assigned by SMC. If it is necessary to modify this address, contact SMC's Tech Support Department.
Confidence Test Utility
A utility provided on the SMC driver diskette can be used to confirm that the board is functioning properly, either during network installation or when troubleshooting an existing network.
To use this utility, first check to be sure the board is connected to a properly terminated Ethernet cable segment. Then, type:
conf_tst
at the DOS prompt, and press the Enter key.
Appropriate pass/fail messages will be displayed in a window and the user will be prompted to return to DOS.

PIN ASSIGNMENTS FOR TWISTED PAIR WIRE
An Ethernet twisted pair cable segment requires two pairs of unshielded wires. Each wire pair is identified by two colors. For example, one wire might be red and the other, red with white stripes. Or the wire pair might be blue and white or green and white, etc.
Each Ethernet twisted pair cable segment must have an RJ-45 connector attached to both ends. The two wire pairs must be connected to pins 1, 2, 3 and 6 on the RJ-45 connector. In addition, the 10BASE-T specification defines the function of these pins. Pins one and two are used for transmitting data; pins three and six are used for receiving data, as shown below:
| RJ-45 Pin | Assignment* |
|---|---|
| 1 | Tx+ |
| 2 | Tx- |
| 3 | Rx+ |
| 6 | Rx- |
* The "+" and "-" signs are used to represent the polarity of the two individual wires that make up each wire pair.
The pins must be connected in a certain orientation. This orientation is dependent upon the presence or absence of a wiring crossover. For 10BASE-T Ethernet, every connection between an adapter, such as the 3016TP/MC, and a concentrator must have a wiring crossover for transmit and receive data. The 10BASE-T specification recommends that the crossover be implemented in the concentrator. The wiring crossover actually takes place in the internal transceiver associated with each concentrator port, and the specification requires that each port supporting the crossover function be marked with an "X."
If the wiring crossover is implemented in the concentrator, as it is in SMC's 10BASE-T concentrators, the two pairs of unshielded twisted pair wires must be straight-through, as shown on the next page:

|---|---|---|---|
| Concentrator Board | |||
| 1 | 1 | ||

If, however, the wiring crossover is not implemented in the concentrator, it must be implemented in the wiring, as shown below:

PIN ASSIGNMENTS FOR TWISTED PAIR WIRE
CONFIGURING THE BOARDS
With the exception of one jumper, JP1, and a pulse transformer, T1 (see the block diagram on the following page), both boards are software-configurable.
The jumper and the pulse transformer are used to select the appropriate cable connector (RJ-45 or AUI for the 3016TP/MC and BNC or AUI for the 3016/MC). Before a board is installed in a Micro Channel Architecture machine, a cable connector must be selected. Once a board has been installed, a configuration program must be run to configure the board to the default settings and to enable some of these settings to be changed.
Instructions for selecting the cable connector and for running the configuration program are provided on the following pages.
Please refer to the manufacturers' instructions for installing expansion cards in each Micro Channel Architecture machine.

Selecting the Cable Connector
The SMC3016TP/MC contains an RJ-45 connector for unshielded twisted pair wiring. The SMC3016/MC contains a BNC connector for Thin Ethernet cabling. Both boards utilize their own on-board transceiver. Additionally, both boards contain an AUI port for connection to a wide variety of media.
With the AUI port, the board may be connected to Thick or Thin Ethernet cable, or to optical fiber or twisted pair wiring. The AUI port requires an external transceiver (MAU) with the appropriate cable tap. In addition, for Thick Ethernet cabling, an AUI cable (external transceiver drop) must be used.

SUMMARY OF CONNECTION RULES
A summary of connection rules for unshielded twisted pair wiring, and both Thick and Thin Ethernet cable, follows.
Note ... Each length of unshielded twisted pair wire must have RJ-45 connectors at both ends. Similarly, each length of Thin Ethernet cable must have BNC connectors at both ends, and each length of Thick Ethernet cable must have N-Series connectors at both ends.
The 5 - 4 - 3 Rule for Configuring Ethernet Networks
Between any two stations on the network, there may be:
- up to five segments in series,
- up to four dual- or multi-port repeaters or concentrators, and
- up to three populated segments (segments connected to PCs) the remaining two segments must be inter-repeater links (unpopulated segments). Note that this applies only to Ethernet 10BASE5 and 10BASE2 networks.
Unshielded Twisted Pair Wiring Rules:
- Stations must be connected point-to-point to a 10BASE-T multi-port wiring concentrator in a star topology.
- Each cable segment joining the station to the concentrator may be a maximum of 328 feet (100m) in length.
- Every connection must have a wiring crossover for transmit and receive data — this crossover function is typically implemented in the concentrator. (Note that SMC's 10BASE-T wiring concentrators do provide an internal crossover and the SMC3016TP/MC board does not.)
Thin Ethernet Cable Rules:
- Up to 30 stations may be connected directly to a single cable segment with BNC T-Connectors.
- Each cable segment may be a maximum of 607 feet (185m) in length and must be terminated at both ends by a 50 ohm BNC terminator. One of the terminators must be grounded. See "Technical Features" for extended distance (1,000 feet / 305m) cable specifications.

- Pairs of cable segments may be linked by a repeater; however, each repeater reduces by one the number of stations allowed on both cable segments. A repeater is connected to a cable segment with a BNC T-Connector.
- The stations and repeaters must be separated by a minimum of 1.5 feet (.5m) of cable.
Thick Ethernet Cable Rules:
- Up to 100 stations may be connected to a single cable segment with transceivers and transceiver (AUI) cables.
- The maximum length of the AUI cable is 165 feet (50m).
- Each cable segment may be a maximum of 1,640 feet (500m) in length and must be terminated at both ends by a 50 ohm N-Series terminator. One of the terminators must be grounded.
- Pairs of cable segments may be linked by a repeater; however, each repeater reduces by one the number of stations allowed on both cable segments. A repeater is connected to a cable segment with a transceiver and a transceiver cable.
- The stations and repeaters must be separated by a minimum of 8.2 feet (2.5m) of cable.
The Ethernet 3016TP/MC board can be connected to:
- a 10BASE-T multi-port wiring concentrator, using up to 328 feet (100m) of unshielded twisted pair wiring.
- any transmission media (Thick or Thin Ethernet, twisted pair or fiber), by attaching the board to the appropriate transceiver and connecting the transceiver to the cable segment.*
The Ethernet 3016MC board can be connected to:
- a Thin Ethernet cable segment, by attaching the board directly to the cable with a BNC T-Connector.
- any transmission media (Thick or Thin Ethernet, twisted pair or fiber), by attaching the board to the appropriate transceiver and connecting the transceiver to the cable segment.*
- * If the transceiver does not allow for direct connection to the board, it may be connected to the board with a transceiver (AUI) cable (maximum 165 feet / 50m).
