8 CHAPTER 1 Intel Express 100BASE-T4 Stackable Hub Media adapter slot The media adapter slot is located in the upper-left corner of the Express 100BASE-T4 Stackable Hub and accommodates two types of o.
2 Installing the Express Hub Requirements Rack installation Standard 19-in. (48.26 cm.) EIA equipment rack requirements 1.5 EIA rack-mount spaces available for each hub Table and shelf Approximately 13.25-in. (33.66 cm.) by 19.25-in. installation requirements (48.
10 CHAPTER 2 Intel Express 100BASE-T4 Stackable Hub CAUTION Don’t connect the power cord to a hub until all hubs are installed, connected together through cascade cables, and ready for operation. Installing a Single Hub To install the hub in a rack 1 Attach the mounting brackets to the sides of the hub.
11 Installing the Express Hub CHAPTER 2 Stacking Hubs You can install a maximum of six hubs in an equipment rack or on a shelf or a table. Once the hubs are stacked and secured, connect them using Intel cascade cables. The cascade cable is a unique cable for Express Stackable Hubs.
12 CHAPTER 2 Intel Express 100BASE-T4 Stackable Hub Installing Uplink Modules You can install an optional 100BASE-TX or 100BASE-FX uplink module in the media adapter slot.
13 Installing the Express Hub CHAPTER 2 Adding a Network Management Module (NMM) After powering down the hub, install the NMM in the hub at the top of your stack.
Connecting the Devices Connecting Cables to the Hub Connect devices directly to ports on the Express 100BASE-T4 Stackable Hub or to ports on installed uplink modules. This illustration shows how to connect a UTP cable to an RJ-45 connector and a fiber optic cable to an SC connector.
16 CHAPTER 3 Intel Express 100BASE-T4 Stackable Hub You can connect the following 100 Mbps devices to the ports on the Express Stackable Hub and optional uplink modules: • Workstations • Servers .
17 Connecting the Devices CHAPTER 3 • The Data % LEDs light green on each hub, indicating the overall network utilization percentage of the Ethernet segment. Because a stack of hubs is a single segment, utilization is the same for each hub in the stack.
18 CHAPTER 3 Intel Express 100BASE-T4 Stackable Hub Unit Numbering Convention When Express Hubs are stacked, cascaded, and powered, they are assigned “unit” numbers that are stored in the hub’s nonvolatile memory. Hub numbers are assigned according to a hub’s physical location in the stack.
19 Connecting the Devices CHAPTER 3 Using a Switch to Connect Hubs Integrating switching into the network enables network segmentation, which increases the total capacity and performance. You can add 100 Mbps workgroups to the network and connect them to individual ports on a Fast Ethernet switch.
20 CHAPTER 3 Intel Express 100BASE-T4 Stackable Hub Connecting to Non- 100BASE-T4 devices Connecting to 100BASE-TX devices You have two options for connecting the Express 100BASE-T4 Stackable Hub to a.
21 Connecting the Devices CHAPTER 3 Routing server If you’re using a NOS that supports multi-protocol routing, such as Novell NetWare * or Windows NT * , an inexpensive way to connect the 100BASE-T4 and 100BASE-TX segments is to install both a 100BASE-T4 and 100BASE-TX LAN adapter in your server and let the server bridge the segments.
22 CHAPTER 3 Intel Express 100BASE-T4 Stackable Hub 100BASE-TX Uplink Module and 10/100 Downlink Intel’s 100BASE-TX Uplink Module fits in the hub’s media adapter slot and allows you to connect to 100BASE-TX devices, such as the Express 10/100 Downlink.
Fast Ethernet Topology Rules This appendix describes • 100BASE-T physical layer media specifications • repeater rules For a complete explanation of the set of 100BASE-T rules and guidelines, refer to the Institute of Electrical and Electronics Engineers (IEEE) 100BASE-T 802.
24 APPENDIX A Intel Express 100BASE-T4 Stackable Hub Media Cable Connector Coding specification type(s) type(s) scheme 100BASE-T4 CAT 3, 4, 5 UTP RJ-45 8B/6T (4-pair wire) 100BASE-TX CAT 5 UTP RJ-45 4B/5B (2-pair wire) 100BASE-FX 62.
25 Fast Ethernet Topology Rules APPENDIX A Repeater rules The 100BASE-T standard defines two types of repeaters — Class I and Class II. The Express Stackable Hub is a Class I repeater. Class I repeaters (sometimes called translational repeaters) limit the number of repeaters in a physical domain to one.
26 APPENDIX A Intel Express 100BASE-T4 Stackable Hub Network Topology Extensions You can extend the network topology by connecting Express Stackable Hubs to a switching hub. In the illustration below, the network topology is extended to a maximum of 400 meters (1312 feet).
27 Fast Ethernet Topology Rules APPENDIX A In the next illustration, the network topology is extended to a maximum distance of 491 meters (1610 feet). In this network, a 160 meter (524 feet) fiber link connects the 100BASE-TX repeater to the switch, and a 131 meter (429 feet) fiber link connects the 100BASE- T4 repeater to the switch.
28 APPENDIX A Intel Express 100BASE-T4 Stackable Hub You can extend the 100BASE-T network topology further by interconnecting the switches using fiber links. Interconnecting two switches creates a network that contains four separate collision domains.
