Chapter 1 Overview This manual describes the hardware features and installation procedures for ATI’s set of independently manageable TurboStack™ (TS) hubs. The TurboStack family also includes “Slave” modules that are not manageable as standalone devices (the AT-TS12FS/SM, ST, SC; AT-TS24TS; and AT-TS24TRS models). These devices have their own manual and are not described here.
PAGE 19
Overview The TurboStack department concentrator chassis can be configured to connect hubs across a standard (or non-segmented) backplane. In this configuration, a fully populated department concentrator comprising eight hubs behaves as a single hub in the network topology. This enables you to build and reconfigure networks easily, efficiently, and at minimum expense.
PAGE 20
TurboStack Hubs with Management ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ Hubs with Management Three types of network management capability: — SNMP — Via ASYNC ASCII terminal port (Omega) — Telnet (Omega) Software upgrade through firmware cassette or in-band downloading Hot swapping of modules in chassis Comprehensive diagnostic LED support Storage of up to 300 addresses per hub module Updates to the MAC address table are effected dynamically in Learning Mode or manually by the user.
PAGE 21
Overview Hubs without Management In addition to the TurboStack hubs with management, ATI offers six models without management (i.e., Slave modules). When used in conjunction with the managed hubs listed in Table 1, the TurboStack Slave hubs become SNMP manageable. Table 2 details the specific model number, port count and media/connector type available for these Slave hubs.
PAGE 22
TurboStack Hubs with Management You can use any combination of TurboStack and AT-3600 Series hubs in the same department concentrator. In this configuration, however, only the management features of AT-S4 firmware apply to all the installed department concentrator units. You must install only TurboStack hubs in the same department concentrator to enable the full range of TurboStack features running AT-S10 firmware,. Note Not all slots have to be populated and populated slots do not have to be contiguous.
PAGE 23
Overview In the seven-slot department concentrator shown in Figure 2, up to 90 ports can be monitored: ❑ One Master containing eight 10BASE2 station ports ❑ Two hubs with management containing a total of twelve (RJ-21) 10BASE-T station ports, twenty-four (RJ-45) station ports, and two AUI ports ❑ Two hubs with management containing a total of six (SC) 10BASE-FL station ports, twelve (ST) 10BASE-FL station ports, and two AUI ports ❑ One Slave hub containing twenty-four RJ45 station ports for UTP (The

TurboStack Hubs with Management Chassis Options ATI offers a variety of desktop and rackmount chassis. These chassis are available with either standard or segmented backplane configurations. Chassis with Standard Backplane An ATI chassis equipped with a standard backplane can hold up to a maximum of eight TurboStack hubs connected through the standard backplane mounted in the inside back wall of the chassis. Figure 3 shows ATI’s 8-slot chassis with fans and standard backplane.
PAGE 25
Overview Chassis with Segmented Backplane In a 7-slot segmented backplane chassis, you can install up to six TurboStack hubs (i.e., one Master and five manageable modules). The seventh slot is available for a switch. The 7-slot TurboStack department concentrator chassis incorporates a factory-installed segmented backplane, shown inFigure 4.
PAGE 26
TurboStack Hubs with Management 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 27
Overview MAC Address Every “intelligent” ATI hub (i.e., hubs with management capability) is provided with a factory-installed unique 6-byte (12-digit) Media Access Control (MAC) address. This address includes a 3-byte (6-digit) company identification number. The MAC address is a unique number assigned to each node using the network. These MAC addreses are used to resolve conflict when multiple computers are trying to access the network simultaneously.
PAGE 28
Chapter 2 Hardware Installation Site Preparation Attention Improper installation of the chassis can expose personnel to high voltages, risking the possibility of injury or death. Before installing TurboStack hubs, read the See Electrical Safety and Installation Requirements on page i. Location Ventilation A TurboStack hub can operate as a standalone product, or installed in a chassis or in a 19-inch rack.
PAGE 29
Hardware Installation Installing Hubs This section contains two separate procedures for installing manageable TurboStack hubs: ❑ ❑ Standalone installation Installation in a chassis Installing a standalone hub The following procedure details how to install a TurboStack hub in a standalone configuration: 1. Plug one end of the power cord into the repeater’s power receptacle and the other end into a power outlet. 2. Check to see that the Power and Master indicators illuminate.
PAGE 30
TurboStack Hubs with Management 1. Every TurboStack hub is shipped with a dust cover on the interrepeater bus port, located on the back of the TurboStack module, to prevent static discharge and/or damage to the connector pins. Before the module is installed in a chassis, the dust cover must be removed, as shown in Figure 6.
PAGE 31
Hardware Installation Note When inserting or removing repeater modules (using the hot swapping method), you must be sure that the power cord is plugged in. To enable hot swapping, you must disconnect the module from the backplane before you unplug the power cord. 4. Flip open (toward you) the two plastic doors on either side of the repeater front panel. (See Figure 9 below.) 5. Align the guide rails on either side of the module with the grooves in the chassis slot.
PAGE 32
TurboStack Hubs with Management 10. Secure the module in the chassis slot by screwing the module in place (see Figure 9). Then, snap closed the plastic doors. Chassis frame Module guide rail Plastic door/handle Module screws Figure 9: Installing a Module in a Chassis 11. Connect your data cables to the hub and the network. Check the Link indicators. 12. If one or more of the ports on the module are transferring data, the Receive indicator will illuminate. 13.
PAGE 33
Hardware Installation Note If you have configured your chassis with both AT-3600 Series modules and TurboStack modules, you will need to refer to the AT-3600 Series Hub/ Repeaters and AT-S4 Firmware Module Network Operations Manual. The AT-S10 software will not run on a chassis configuration that includes both AT-3600 and TurboStack modules. See your ATI sales representative for further details.
PAGE 34
TurboStack Hubs with Management The principal use for the RS232 port is connection of a local network management terminal to access Omega. For more information, refer to the TurboStack™ AT-S10 Firmware Module for TurboStack Hubs Operations Manual. AUI Appliqué Port Each manageable TurboStack hub has a convertible AUI port located on the front panel. You may use this port to connect the hub to the network.
PAGE 35
Hardware Installation You can combine any TurboStack hub model type with any of the six network port appliqués listed in Table 3. Table 3: ATI Network Port Appliqués Model Description AT-TSA1 SM/SMA Fiber Optic Port AT-TSA2 SC Fiber Optic Port AT-TSA3 ST Fiber Optic Port AT-TSA5 AUI Port AT-TSA8 BNC Port AT-TSA9 RJ45 Port Note In swapping appliqués, it is advisable to turn off power to the hub since you will be loosening screws and installing metal parts through the appliqué port.
PAGE 36
TurboStack Hubs with Management Network Appliqué Installation In a TurboStack department concentrator chassis, you can connect manageable hubs to network zones using different cable media by installing different appliqués. Location of Appliqué Port To install or remove an appliqué, find the TurboStack hub appliqué port. As shown in Figure 12, this port is located directly to the left of the RS232 terminal port on the module faceplate (in this case an AT-TS06F/SC model hub).
PAGE 37
Hardware Installation 2. Detach the AUI appliqué assembly from the hub faceplate by loosening the two M3x6 flat-head screws to the far right and left on the connector plate, shown in Figure 13. M3x6 flat-head screws Connector plate Figure 13: AUI Appliqué Assembly AUI connector Note Do not unscrew the AUI slide kit screws that secure the AUI connector to the appliqué plate until the entire appliqué assembly (i.e., AUI connector, connector plate, and attached ribbon cable) pops out.

AT-TS24TR Connectivity RJ45 Connectors The AT-TS24TR uses 24 RJ45 connectors, thus eliminating the need for a Telco-type cabling adapter. Figure 51 shows a sample RJ45 connector. Pin 1 Figure 51: RJ45 Connector MDI/MDI-X Switch The 24 10BASE-T RJ45 ports on the AT-TS24TR are generally used for network connections between the hub and a transceiver. Network connections require a standard “straight-through” cable, meaning that a pin at one end connects to a pin with the same number at the other end.

Appendix A UTP Reference 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.

UTP Reference UTP Hub-to-MAU Wiring Figure 54 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 55. Pin 1 Figure 54: RJ45 Cable A 1 Pair twisted as per Level 3, 4 or 5 cable.
PAGE 73
TurboStack Hubs with Management 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 56.

Telco Reference 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.

IEEE 802.3 Quick Primer 10BASE-FL/FOIRL Ethernet The IEEE 802.3 10BASE-FL standard supports up to 2,000 meters (6,560 ft.) of multimode duplex fiber optic cable in a point-to-point link which directly attaches two devices. FL is compatible with FOIRL, but FOIRL only supports connections of 1,000 meters (3,280 ft.). Duplex refers to support for fiber optic cable pairs, enabling a two-cable fiber optic connection with transmit mode dedicated to one cable and receive mode to the other.

TurboStack Hubs with Management Propagation Propagation delay is the time it takes a signal to travel from the input of a system component to the output; it is usually measured in nanoseconds. IEEE 802.3 has specific propagation delay maximums for the Ethernet components. Cable length plays a major role; i.e., a 50 meters (164 ft.) AUI cable has a maximum propagation delay of 257 ns. The propagation delay of cable depends on the length and velocity factor of the cable type.
PAGE 81
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.

TurboStack Hubs with Management 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.
PAGE 84
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 Hubs with Management 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.
