Chapter 1 Overview This manual describes the hardware features and installation procedures for ATI’s set of TurboStack™ (TS) hubs that are not manageable as standalone devices. These “Slave” devices include the AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS models. For information on the software installation and network management aspects of TurboStack hubs, refer to the separate TurboStack™ AT-S10 Firmware Module for TurboStack Hubs Operations Manual.
PAGE 18
Overview Note For a detailed explanation of ATI’s TurboStack chassis/backplane offerings, refer to the TurboStack™ Chassis and Backplanes Installation Manual. This manual describes the physical features and installation procedures for the chassis models. See your ATI sales representative for further details. Data Port Connectors TurboStack hubs are based on ATI’s proprietary Application-Specific Integrated Circuit (ASIC) developed for maximum functionality and reliability.
PAGE 19
TurboStack Series Hubs The AT-TS24TS and AT-TS24TRS model hubs differ from the AT-TS12FS/ SM, SC, and ST hub models primarily because each AT-TS12FS series model has 12 paired fiber optic (10BASE-FL) ports on the front panel of the unit. Also, unlike the AT-TS24TS and AT-TS24TRS model hubs, the AUI backbone port is mounted on the front panel of AT-TS12FS/ST, SC, and SM hubs. Figure 2 shows the AT-TS24TS faceplate with two 50-pin Telco data port connectors.
PAGE 20
Overview Hub Features Table 1 summarizes the physical features of the AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS hubs without management. Specifically, this table identifies the model number, port count, and media/connector type for each Slave device.
PAGE 21
TurboStack Series Hubs Controllers Hubs with Management All three of the TurboStack Slave hubs use an ATI proprietary multiple port repeater controller to retime and regenerate signals and communicate with the network management software. The port status for each of the ports is indicated by an LED display. For any of these three hubs to be manageable, another hub with management must perform as a Master in the chassis. Table 2 lists the TurboStack hubs that can function as Master.
PAGE 22
Overview Chassis Configuration Commonly called “Slave” hubs because of their dependence on a “Master” repeater for management, the AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS models can function in any of the following four configurations: ❑ As a standalone repeating device without management: A standalone Slave hub performs simple regeneration and retiming tasks in a variety of network configurations. This configuration can use the hub’s AUI port to connect to a network backbone.
PAGE 23
TurboStack Series Hubs Note Not all slots have to be populated, and populated slots do not have to be contiguous. The Master is the top-most module. Any Slave above the Master will not be managed. Standard Backplane An 8-slot ATI chassis equipped with a standard backplane can hold a maximum of eight TurboStack hubs connected through the standard backplane mounted in the inside back wall of the chassis. Figure 4 shows ATI’s 8-slot chassis with fans and standard backplane.
PAGE 24
Overview Segmented Backplane In a 7-slot chassis with a segmented backplane, you can install up to six TurboStack hubs (i.e., one Master and five manageable modules). The seventh slot is available for a switch. As shown in Figure 5, the 7-slot TurboStack department concentrator chassis incorporates a factory-installed segmented backplane.
PAGE 25
TurboStack Series Hubs Slave Module Slave modules (AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS) may occupy any other higher-numbered slot position in the chassis except Slot 7 (the bottom slot). They do not need to be adjacent or contiguous. In other words, Slave units may be separated by empty chassis slots. TurboStack Department Concentrator Figure 6 shows a sample TurboStack department concentrator using the 7-slot chassis model.
PAGE 26
Overview Note Depending on the model used, the AUI network port on some Slave modules cannot be used in a seven-slot department concentrator because they reside on the back panel of the repeater and are blocked by the backplane. Module Functions In the department concentrator configuration, the modules perform different functions: ❑ The top module becomes the Master. It downloads software to and serves as the reporting unit for other units in the concentrator. It also controls the management functions.
PAGE 27
TurboStack Series Hubs Network Management Network Management Planning Before installing and connecting manageable TurboStack hubs at various site locations (such as in closets in a single building or in closets on different floors or in different buildings), you need to decide on the number of hubs in your network and where each hub is to be located. This advanced planning will facilitate the assignment of hub names, MAC and/ or IP addresses.
PAGE 28
Chapter 2 Hardware Installation Installing the TurboStack hubs without management capability simply involves plugging the hub into a power source. Additional specific information on installing the hub in a department concentrator chassis is in the manual included with the chassis.
PAGE 29
Hardware Installation Installing Hubs This section contains two separate procedures for installing TurboStack Slave hubs: ❑ Standalone installation ❑ Installation in a managed hub configuration in a concentrator chassis Installing a standalone repeater The following procedure details how to install a TurboStack hub in a standalone configuration: 1. Plug one end of the power cord into the hub’s power receptacle and the other end into a power outlet. 2.
PAGE 30
TurboStack Series Hubs Attention Improper installation may expose the repeaters to debris and block vents, causing damage because of insufficient cooling. When installing multiple ATI hubs in a chassis with power, setting the chassis voltage switch too high (at 240V when 120V is required) will cause overheating of the fans. Setting the voltage too low (at 120V when 240V is required) will reduce the effectiveness of the fans and thus cause overheating of the installed repeater modules.
PAGE 31
Hardware Installation 1. Every ATI hub is shipped with a dust cover on the interrepeater bus port, located on the back of the module, to prevent static discharge and/ or damage to the connector pins. Before the module is installed in a multi-module chassis, the dust cover must be removed, as shown in Figure 7.
PAGE 32
TurboStack Series Hubs 4. Flip open (toward you) the two plastic doors on either side of the repeater front panel, as shown in Figure 10. Chassis frame Generic Slave hub Module guiderail Plastic door/handle Module screws Figure 10: Installing a Module in a Chassis 5. Align the guide rails on either side of the module with the grooves in the chassis slot, also shown in Figure 10. Then, slide the module into the chassis without seating it in the backplane connector.
PAGE 33
Hardware Installation Attention Upon initial power-up, the LEDs (including the red fault lights) on all units connected through a chassis backplane will activate. This is a normal cycling function and is not any indication of a problem. Note When you power-up a Slave module, its port activity LEDs continuously illuminate in sequence until either management software is downloaded from a Master or a device is connected to one of the ports on the Slave’s front panel. 8.
PAGE 34
TurboStack Series Hubs TurboStack Port Configurations AUI Port TurboStack hubs without management have a fixed AUI port, located on the front panels of the AT-TS12FS/ST, SC, SM models and on the back panels of the AT-TS24TRS and AT-TS24TS models. Figure 11 shows the front panel location of this port on the AT-TS12FS/SC module. Permanent AUI port Figure 11: AT-TS12FS/SC AUI Port Note The permanent AUI port is located on the back panels of the AT-TS24TRS and AT-TS24TS models.
PAGE 35
Hardware Installation Hub Back Panel Features As shown in Figure 12, the back panel features of the AT-TS12FS series hubs include: ❑ Interrepeater bus connector that attaches the TurboStack module to the backplane bus in a concentrator chassis ❑ Status indicators providing information on the hub as a whole; for convenience, these LEDs appear on both the front and back panels of each hub Note TurboStack hubs without management do not have a firmware cassette port.
PAGE 36
TurboStack Series Hubs LED Displays TurboStack hubs have two types of LED displays: ❑ Hub status indicators show the overall condition of the module. ❑ Port indicators show the condition of each port connection. They vary with module type; later chapters of this manual give specifics.
PAGE 37
Chapter 3 AT-TS12FS/ST, SC, SM The AT-TS12FS/ST, SC, SM models are multiport hubs designed to offer maximum flexibility for both workgroup and department needs. Specifically, this series of hubs includes three hub module designs, each with 12 fiber optic (10BASE-FL) ports and an AUI port located on the front panel. Note This manual refers to two or more chassis-mounted hubs, at least one of which is manageable, as a department concentrator. The term hub refers to either a standalone hub (i.e.

PAGE 39
TurboStack Series Hubs Since these models do not incorporate management agent software, they can operate only as part of a non-managed hub or as Slave modules in an ATI department concentrator chassis. Features Table 4 summarizes the features of the AT-TS12FS/ST, SC, SM hubs, including model number, port count, and media connector type.
PAGE 40
AT-TS12FS/ST, SC, SM There are desktop and rackmount department concentrator chassis available to hold from two to eight TurboStack hubs. Since the department concentrator chassis connects hub modules across a backplane, a fully populated department concentrator behaves as a single hub in the network topology. This enables you to build and reconfigure networks easily, efficiently and at minimum expense. An AT-TS12FS series module repeats 10BASE-FL signals according to IEEE 802.3 specifications.
PAGE 41
TurboStack Series Hubs Fiber Optic (10BASE-FL) Wiring Specifications The IEEE FOIRL standard limits a fiber segment length to 1 km (3,280 ft.). That is, the fiber optic cable that connects two hubs is limited to 1 km (3,280 ft.). On the other hand, the more recent IEEE 10BASE-FL standard limits a fiber segment length to 2 km (6,560 ft.). Note, however, that this only applies to topologies in which one 10BASE-FL node connects to another 10BASE-FL node.
PAGE 42
AT-TS12FS/ST, SC, SM Attention The ST connector is keyed. Gently rotate the connector to ensure proper mating of the ST plug receptacle. Be careful not to force the connector mating or you might damage the hub’s connector. Figure 18 shows the square push-pull SC connector. Also shown is the optional duplexing clip. Duplexing Clip Figure 18: SC Connector for Fiber Optic Cabling Attention The SC connector may be installed with an optional duplexing clip, as shown in Figure 19 above.
PAGE 43
TurboStack Series Hubs LED Displays Hub Indicators LED indicators appear on each AT-TS12FS/ST, SC, SM hub. The LEDs intentionally do not reflect real-time activity, because a data packet is too fast for the human eye to distinguish on the LED indicator; therefore, the hub artificially stretches the LED ON time for observation. LED indicators for the AT-TS12FS hub series are described below: POWER—Green whenever power is applied.
PAGE 44
AT-TS12FS/ST, SC, SM FLASHING AMBER—This indicates that the port has a valid link and that there are collisions on the port. NO LIGHT—This indicates that the port is not functioning. If you fail to get a Link light at a particular port, one or more of the following conditions may be occurring: 1. Network device at other end is turned OFF (transmitter is inactive). 2. Cable is damaged or broken, or attenuation is too high (i.e., too little light is being received because the cable is too long). 3.
PAGE 45
Chapter 4 AT-TS24TS The AT-TS24TS is a multiport hub designed to offer maximum flexibility for both workgroup and department needs. Specifically, the AT-TS24TS uses two 50-pin Telco connectors. In addition, you can connect an AT-ADAPT-2, or an octopus cable, to the AT-TS24TS, enabling you to use RJ45 connectors. Note This manual refers to two or more chassis-mounted hubs, at least one of which is manageable, as a department concentrator. The term hub refers to either a standalone hub (i.e.

AT-TS24TS 50-Pin Telco-to-RJ45 Octopus Cables (For Model AT-TS24TS). The 10BASE-T octopus cable breaks out the AT-TS24TS hub 50-pin Telco connector to individual RJ45 connectors for connecting directly into a patch panel in the wiring closet. When purchasing an octopus cable, make sure that it is wired for 10BASE-T 50-Pin Telco-to-RJ45 Harmonica (For Model AT-TS24TS). ATI offers a harmonica adapter, model AT-ADAPT-2.

Port activity LEDs Hub status LEDs Figure 25: AT-TS24TS LEDs The LEDs on the AT-TS24TS hub intentionally do not reflect real-time activity, because a data packet is too fast for the human eye to distinguish on the LED indicator; therefore, the hub artificially stretches the LED “ON” time for observation.
PAGE 50
AT-TS24TS COLLISION (Flashing Amber)—A momentary amber flash occurs when a collision is detected on the port. NO LINK (No Light)—If the link test function is not met by the 10BASE-T device at the opposite end of the UTP segment, this LED will not illuminate. This may occur if the workstation at the end of the segment is turned OFF or if the UTP segment is disrupted or damaged. SELF-TEST (Sequential Flashing Green)—This indicates the hub is conducting a power-ON self-test.
PAGE 51
Chapter 5 AT-TS24TRS The AT-TS24TRS is a multiport hub designed to offer maximum flexibility for both workgroup and department needs. Specifically, the AT-TS24TRS has 24 shielded RJ45 connectors for UTP cable. Since the AT-TS24TRS model does not incorporate management agent software, it can operate only as part of a non-managed hub or as a Slave module in an ATI department concentrator chassis.
PAGE 52
AT-TS24TRS As shown in the above figure, the AT-TS24TRS uses 24 RJ45 connectors for UTP. Since the AT-TS24TRS model does not incorporate management agent software, it can operate only as part of a non-managed hub or as a Slave module in an ATI department concentrator chassis. Features Table 6 summarizes the features of the AT-TS24TRS hub, including model number, port count, and media/connector type for each Slave hub.

Chapter 6 Troubleshooting This section provides a checklist for resolving problems associated with your hub and cabling. The first rule of troubleshooting is to isolate the problem. As you experiment, only vary one factor at a time. Substitute known good equipment to see if the problem persists or is eliminated. As a preliminary check, perform the following steps 1. Do not overlook the obvious—check diagnostic LEDs and make sure the cables and connectors are securely attached. 2.
PAGE 57
Troubleshooting 7. If too many collisions are present on an AUI connection, check to ensure that the external Ethernet transceiver connected to the AUI port has the SQE Test (Heartbeat) function disabled. Excessive network loading can also cause excessive collisions. 8. If a fault occurs (fault light stays ON), disengage the repeater module from the backplane, unplug and replug the power cord, and reseat the module.
PAGE 58
Appendix A UTP Wiring Specifications 10BASE-T requires UTP wiring capable of supporting 10 Megabit data rates. Use Level 3 or better UTP wiring throughout the 10BASE-T wiring system. The wire should be 22 to 26 AWG, 100 Ω impedance with 3 to 8 twists per foot. Typically, if a cable is flat, the pairs are untwisted and will cause problems. A cable more or less round in section is likely to be twisted.
PAGE 59
UTP Wiring Specifications UTP Hub-to-MAU Wiring Figure 30 shows a UTP cable with an RJ45 connector. For a 10BASE-T link between a hub and a Medium Attachment Unit (MAU) or Network Interface Controller (NIC), the cable is wired straight-through. That is, an RJ45 receptacle at the hub would wire pin-to-pin to the RJ45 receptacle at the MAU, as shown in Figure 31. Pin 1 Figure 30: RJ45 Cable A 1 Pair twisted as per Level 3, 4 or 5 cable.
PAGE 60
TurboStack Series Hubs UTP MAU-to-MAU, Hub-to-Hub Wiring 10BASE-T MAU-to-MAU or hub-to-hub wiring generally requires a crossover cable located somewhere along the UTP cable run. This may commonly occur at the punch-down block or between the RJ45 wall receptacle and the workstation. See Figure 32.

Telco (RJ21) Connection Specification Accessories 50-Pin Telco-to-RJ45 Octopus Cables The 10BASE-T ‘octopus’ cable breaks out the AT-TS12T or AT-TS24T Hub 50-pin Telco connector to individual RJ45 connectors. This is an ideal method for connecting into a patch panel in the wiring closet. Patch panels allow for easy configuration and reconfiguration of house wiring requirements. When you purchase an octopus cable, ensure that it is wired for 10BASE-T and that Level 3 UTP is used.

Appendix C IEEE 802.3 Quick Primer 10BASE-T 10BASE-T UTP media were implemented to reduce Ethernet wiring costs. UTP wiring is installed in most buildings for telephone systems. Make sure the UTP wiring used for 10BASE-T is able to carry the high Ethernet data rates before you implement a 10BASE-T network solution. Unlike coaxial Ethernet, 10BASE2 and 10BASE5, 10BASE-T UTP is point-to-point wiring.
PAGE 66
IEEE 802.3 Quick Primer 10BASE2 (Thin) Ethernet When configuring thin coax segments, IEEE 802.3 specifications allow up to 30 MAU attachments per cable segment, spaced at no less than 0.5 meters (1.64 ft.). The 10BASE2 cable length cannot exceed 185 meters (606 ft.) per segment. The worst-case propagation delay for a 185 meter (606 ft.) thin Ethernet segment is 950.9 ns. The propagation delay for thin (10BASE2) Ethernet cable is 5.14 ns/meter.
PAGE 67
Appendix D Glossary 10BASE2—Also called thin Ethernet, thinnet or CheaperNet, a 10 MHz baseband specification. Cable impedance is 50 Ω and maximum coaxial segment length is 185 meters (607 ft.). 10BASE5—Also called thick Ethernet, a 10 MHz baseband specification. Cable impedance is 50 Ω and maximum coaxial segment is 500 meters (1,640 ft.). The cable is commonly referred to as yellow cable. Thick Ethernet cable is typically used as a trunk or backbone path for the network. 10BASE-FL—IEEE 802.
PAGE 68
Glossary BAYONET NUT COUPLE (BNC) CONNECTOR—A 10BASE2 thin coax connector with push-on BNC locking lug. This lug quickly locks into place with a half twist. BIT RATE (BR)—The rate of data throughput on the medium in bits per second. Ethernet specifies 10 million bits per second. BIT TIME—The duration of one bit symbol (1/BR). Ethernet specifies a bit time of 100 ns. CARRIER SENSE—In a LAN, an ongoing activity of a data station that detects whether another station is transmitting.

TurboStack Series Hubs DEPARTMENT CONCENTRATOR—Hub that provides a large number of workstation connections. The term department concentrator refers to multiple repeaters housed in an AT-CTS 7-slot or AT-C36C 8-slot chassis. See Hub/ Repeater, Repeater. DIX CONNECTOR—See D-Sub Connector FOIRL — A fiber optic standard that allows up to 1,000 meters (3,280 ft.) of multimode duplex fiber optic cable in a point-to-point link.

Glossary LINK TEST—In 10BASE-T Ethernet, there is a link test function that validates the UTP link. This consists of a pulse transmitted from point A on one pair that is validated at point B. Point B also transmits a pulse on the second pair to be validated by point A. These pulses occur during media idle states (in between packets). MANAGED MODULE— An intelligent repeater in a department concentrator chassis that makes management data available to the Master.

TurboStack Series Hubs PROPAGATION DELAY—The time required for a signal to travel from the input of a system component to the output. Usually measured in nanoseconds. IEEE 802.3 stipulates specific propagation delay maximums for computing propagation budgets when you design a LAN. Cable length plays a major role in propagation delay; for example, a 50-meter (164-foot) AUI cable has a maximum allowable propagation delay of 257 ns.

Glossary TCP/IP PROTOCOLS—A set of protocols for intercomputer communication, including network level (Internet Protocol), transport level (Transmission Control Protocol or TCP) and application level protocols (for example, Telnet terminal emulation). TCP/IP has been used for many years in two country-wide networks, the ARPANET and MILNET. Recently, TCP/IP has become very popular with users of a variety of multi-user computer systems and engineering workstations.
