Page 6: About This Guide
This guide discusses how to install and use your Ethernet/Fast Ethernet dual-speed stackable hub. Conventions As used in this guide, the term hub, unless otherwise noted, refers to the eight- or sixteen-port Ethernet/Fast Ethernet dual-speed stackable hub with which this guide was packaged, or to another hub in the same product family. - Page 7 Dual-Speed Stackable Hub User’s Guide ♦ Appendix A, Cables and Connectors. Provides specifications on the cables and connectors used with the hub. ♦ Appendix B, Specifications. Lists the hub’s specifications. About this Guide...

Page 9: Introduction
This means you can connect all of your Ethernet and Fast Ethernet hosts to your hub (or to a stack of hubs in the same product family) without any rewiring required when a host is upgraded from 10 Mbps to 100 Mbps. -
Page 10: Product Features
100-Mbps Fast Ethernet nodes and vice versa, regardless of which hub in the stack any node is attached to. Note that if two or more hubs in a stack have switching circuits built in, only one hub’s switching circuit will be enabled; any other switching circuits in the stack will automatically be disabled, and only one hub’s SW Enable indicator will shine. - Page 11 ♦ Daisy-chaining ports for interconnecting up to five hubs to form one logical hub. ♦ Uplink jack for easy linking of two hubs or hub stacks (or of a hub to a stack) to further expand the network. ♦ Optional brackets for mounting in a standard 19-inch equipment rack.

CAD/CAM. To utilize 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 (100 Mbps) have been adopted by many vendors. -

Page 15: 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 retranslating them back to line signals. -

Page 19: Uplink Jack
Crossover Cables on page ♦ Uplink Jack The Uplink jack is an MDI-II jack, which means you can connect the hub (or a hub stack) to a device with an MDI-X port using an ordinary straight-through cable, making a crossover cable unnecessary. -

OUT port of the previous hub in the stack (usually placed immediately above it). A stack of five hubs can be created in this way. The first and last hubs in the stack use only one of the daisy-chaining ports, while the others use both. -

(such as motors), vibration, dust, and direct exposure to sunlight. ♦ Leave at least 10 cm of space at the front and rear of the hub for ventilation. ♦ Install the hub on a sturdy, level surface that can support its weight. -

Page 24: Hub State Indicators
If a hub with a switching circuit is used alone (that is, not in a stack), its SW Enable indicator will shine all the time, even if all devices connected to the hub operate at the same speed. -
Page 25: Port Speed Indicators
Port Status Indicators There is one port status indicator for each of the hub’s twisted-pair ports. When a good link to a powered-up but idle device is detected on a port, the port’s status indicator shines steadily. When packets are received from the device, the indicator blinks off and on. -
Page 27: Making Connections
80 twisted-pair ports. Never connect or disconnect a daisy-chaining cable while the power is on to the hub or to any other hub in the stack. Always turn off power to the entire stack before adding or removing a hub or hubs. -
Page 28: Connectivity Rules
If more than one hub in the stack has a switching circuit, only one hub’s SW Enable indicator will light up, and that hub will provide 10-Mbps/100-Mbps intercommunication capability for all end nodes connected to the stack. -

Type 1 STP with RJ-45 plugs). ♦ The maximum diameter of a collision domain is 205 meters using two Class II hubs (or two hub stacks, or one hub and one stack) uplinked together. ♦ Between any two end-stations in a collision domain, there may be up to three cable segments and two Class II hubs (or two hub stacks, or one hub and one stack). - Page 30 Each Fast Ethernet connection requires either a Category 5 UTP cable or a Type 1 STP cable. These cables can be up to 100 meters long. Each Ethernet connection requires a Category 3 or better UTP cable. It is recommended that you use Category 5 cabling for all connections in order to make it easier to transition all stations to 100 Mbps.

Dual-Speed Stackable Hub User’s Guide Uplink Connection You can “uplink” two hubs (or two hub stacks, or a hub and a stack) to each other using either (a) any two numbered X-type jacks or (b) a numbered X-type jack and an Uplink jack. (In the... - Page 32 When you uplink two hubs together, the maximum distance between any two end nodes in a collision domain is 205 meters. If both hubs have maximum-length (100-meter) connections to end nodes (even if there is only one such connection on each hub), the hub-to-hub uplink connection will be limited to 5 meters.

♦ Cable characteristics: Category 5 unshielded twisted-pair or EIA/TIA-568 compliant, 100-ohm shielded twisted-pair data cable with 0.4 to 0.6 mm (22 to 26 AWG) wires in two or four twisted pairs (only two pairs—that is, four wires—are used for 100BASE-TX). -
Page 36: Crossover Cables
Crossover Cables When making an uplink connection between one hub and another (or between a hub and a switch or bridge) using X-type jacks at both ends, you must use a crossover cable. In a crossover cable, two pairs of wires are switched at one end. Carry out the following... - Page 37 Dual-Speed Stackable Hub User’s Guide At the other end of the cable, connect wires 1 and 2 to contacts 3 and 6, respectively.
