Page 11: About
TE100-DS24X. Managed Models: TE100-DM16, TE100-DM16X, TE100-DM24, TE100-DM24X. All “X” models include a switch module in Slot 1 of the rear panel. All “M” models are intelligent (that is, “managed”) hubs capable of managing an entire hub stack. The model numbers also indicate how many ports a particular hub has, thus: DM16/DS16 hubs have 16 ports and DM24/ DS24 hubs have 24 ports. -

Page 15: Chapter 1 : Introduction
10Mbps to 100Mbps. The TE100-DM/DS series hubs, available in 16-port and 24-port models, can be stacked with up to five hubs in a stack. A stack of five 24-port hubs gives a total of 120 Ethernet or Fast Ethernet ports. -
Page 16: Product Features
1 0Mbps and 100Mbps segments. In a managed hub stack, more than one switch module can be used to provide redundancy if the two modules are both in the primary master hub segment. Other add-in modules are also available, providing switched 100BASE-TX, or switched 100BASE-FX connections. - Page 17 An optional slide-in switch module allows bridging b etween 10Mbps and 100Mbps segments. Only one switch module is needed per stack, but managed hub stacks can make use of additional switch modules for redundancy. LED indicators for power, collisions, link, network activity, partitioning status, disable, operating speed (10 or 100Mbps) and network utilization.

Page 18: Dual-Speed Ethernet Hub
100BASE-FX (see Chapter 4 : Making Connections). Dual-Speed Ethernet Hub Technology Overview Dual-speed Ethernet hubs have been developed to make it simpler to plan networks containing both 10Mbps Ethernet and 100Mbps Fast Ethernet technologies, especially when network hosts are being gradually migrated to new Fast Ethernet connections. -
Page 19: 100Base-Tx Technology Overview
CAD/CAM. To util- ize these technologically advanced applications more efficiently, there is also a growing demand for faster networks that can handle heavy network traffic. Recognizing this need for greater bandwidth and lower latency, a variety of technologies such as FDDI, ATM, and Fast Ethernet (100Mbps) have been adopted by many vendors. -
Page 20: Cables And Connectors

Page 21: Network Diameter
Unlike 10BASE-T hubs which are all functionally identical, Fast Ethernet hubs are divided into two distinct types: Class I and Class II. A Class I hub repeats all incoming signals on one port to the other ports by first translating them to digital signals and then re- translating them back to line signals. - Page 22 Dual-Speed Stackable Hubs User’s Guide TX to TX. At most, two Class II hubs can exist within the same col- lision domain. As mentioned earlier, stackable Class II hubs can be used to increase the number of available nodes in a collision domain. An entire hub stack counts as a single repeater.

Page 23: Chapter 2 : Unpacking And Setup
This chapter provides information on the unpacking and initial in- stallation of your hub stack. Unpacking Open the shipping carton of your hub and carefully unpack the con- tents. The carton should contain the following items: One dual-speed stackable hub One AC power cord, suitable for your area’s electrical power... -

LED indicators. Twisted-Pair Ports Use any of these ports to connect stations to the hub. The ports are MDI-X Nway ports, which means you can use ordinary straight-through twisted-pair cable to connect the hub to PCs, workstations, or servers through these ports, and the speed of the connection will be detected automatically. -

Daisy-Chain OUT port of the previous hub in the stack (usually placed immediately above it). A cascade of five hubs can be created in this way. The first and last hubs in the stack use only one of the daisy-chain ports, while the others use both. -
Page 27: Installing The Hub
The site where you install the hub stack may greatly affect its per- formance. When installing, consider the following pointers: Install the hub stack in a fairly cool and dry place. See A p- pendix D, Specifications, for the acceptable temperature and humidity operating ranges. -
Page 28: Rack Mounting
Dual-Speed Stackable Hubs User’s Guide Leave at least 10cm of space at the front and rear of the hub for ventilation. For more information see, “Environmental and Physical” on page 84. Install the hub on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. -
Page 29: Replacing The Power Supply
Replacing the Power Supply The hub comes with a removable power supply for easy replacement. In the unlikely event that the power supply fails or is damaged, fol- low the steps below to replace it: Disconnect the power cord from the AC outlet. - Page 30 Dual-Speed Stackable Hubs User’s Guide Slide the replacement power supply into the chassis, engaging the connector carefully. Attach the power cord to the connector of the power supply and connect the other end of the power cord to the AC supply source.

These indicators indicate data collisions on the respective 10Mbps Ethernet or 100Mbps Fast Ethernet segments of the hub. (If sev- eral hubs are stacked or linked together, all of them should detect and indicate the same collision, since collisions span the entire network segment.) Whenever a collision is d etected, the respec-... -

The indicator of a port lights green when the port is connected to a powered Ethernet or F ast Ethernet station. If the station to which the hub is connected is powered off, or if there is a problem with the link, the LED will remain off. -
Page 35: Snmp Indicator
(Master models only.) This indicator comes on when the SNMP agent of a TE100-DM/DS series master hub is active. In a stack with both a Primary and a Backup Master, the SNMP LED of the Primary master will be lit and will flash to indicate SNMP activity. -
Page 36: Console Port Indicator (Con)
Console Port Indicator (CON) (Master models only.) This indicator lights continuously under the following two conditions: 1. A good connection has been established with a console (for e x- ample, a PC or other computer). The diagnostic port of a TE100-DM/DS series master hub must be connected to the console's RS-232 serial port using a normal serial cable. -

120 twisted-pair ports. Use the provided daisy-chain cable to connect the Daisy-Chain OUT port on the rear panel of one hub to the Daisy-Chain IN port on the hub below it, as shown in the figure below. Repeat this procedure for each hub to be included in the stack. - Page 38 Dual-Speed Stackable Hubs User’s Guide Hubs should not be added to the stack or removed from the stack while the power is on at any hub in the stack. Note: Always turns off power to the entire stack before adding or removing hubs.

You can also access the same functions over a TELNET link. Once you have set an IP address for your hub (see the beginning of this chapter), you can use a TELNET program (in a VT-100 compatible terminal mode) to access and control the hub. All of the screens are for the most part identical, whether accessed from the diagnostic port or from TELNET. - Page 42 (TE100-DS24, TE100-DS24X, TE100-DM24, TE100- DM24X) end-station connections. Fast Ethernet connections require either a Category 5 UTP cable or a STP cable. These cables can be up to 100 meters long. Each Ethernet connection requires a Category 3 or better UTP cable.
-
Page 43: Hub-To-Hub Uplink
Hub-to-Hub Uplink You can link two hubs or hub stacks to each other using any of the twisted-pair ports or the Up-link port. Linking hubs using ordinary twisted-pair ports requires crossover twisted-pair cables; linking us- ing one ordinary twisted-pair port and the Up-link port requires an ordinary straight-through twisted-pair cable. - Page 44 Server (or PC) Crossover (X) A crossover cable is a straight-through twisted-pair cable in which the wires have been crossed. The figure below shows the pin a s- signments for an Ethernet or Fast Ethernet crossover cable: NOTE: The first twisted-pair port (Port 1) is logically shared with the Up-link port.

Page 45: Optional Module Connections
Optional Module Connections There are three optional modules that may be added to any of the TE100-DM/DS series hubs. Each hub can accommodate two mod- ules. Each of the modules offers a different additional network interface that allows for greater flexibility in how these hubs may be used in a network. -
