C H A P T E R 1 Intel Express 100BASE-TX St ackable Hub 2 – 100BASE-T Media adapter slot to accommodate an optional media adapter that allows the repeater to be connected to other 100BASE-T network devices.
CHAPTER 1 O v e r v i e w 3 Chassis The Express hub components are enclosed in a 19-inch (48.26- centimeter) wide chassis, which is 1.5 EIA rack-mount spaces high. The chassis consists of a metal frame and a plastic front panel, and it contains components that are pertinent to the operation of the hub.
C H A P T E R 1 Intel Express 100BASE-TX St ackable Hub 4 Front Panel The front panel of the Express hub provides 12 100BASE-T ports, an MDI/MDI-X switch, an LED matrix, a media adapter slot, and an expansion slot.
CHAPTER 1 O v e r v i e w 5 The maximum cable distance between the port and the attached device is 100 meters (328 feet), including all patch cables, panels, and connectors. MDI/MDI-X Switch The MDI/MDI-X switch on the front panel of the Express hub is a recessed push-button switch that allows you to select MDI or MDI-X wiring for port 1.

C H A P T E R 1 Intel Express 100BASE-TX St ackable Hub 8 100BASE-T Media Adapter Slot The media adapter slot is located in the upper left-hand corner of the Express hub and accommodates an optional 100BASE-T media adapter. A 100BASE-T media adapter allows you to connect to other 100BASE-T network devices using a different media.
CHAPTER 1 O v e r v i e w 9 Rear Panel The rear panel of the Express hub provides an AC power receptacle, a Redundant Power connector, and two cascade cable connectors.
C H A P T E R 1 Intel Express 100BASE-TX St ackable Hub 10 The cascade cable extends the functionality of one hub to a maximum of six hubs in a stack. This stack then functions as a single repeater or collision domain.

C H A P T E R 2 Intel Express 100BASE-TX St ackable Hub 14 Installing an Express hub This section provides information and instructions for installing a single Express hub in a rack or on a table or shelf. For instructions on installing multiple Express hubs, see “Installing Multiple Hubs” later in this chapter.
C H A P T E R 2 Installi ng and Removing the Express Hub 15 3. Insert two pan-head screws with nylon washers through each mounting bracket and into the rack. 4. Using a #2 Phillips screwdriver, tighten the screws to secure the hub to the rack. 5. Continue with “Completing the Installation” to finish this installation procedure.
C H A P T E R 2 Intel Express 100BASE-TX St ackable Hub 16 2. Install any optional modules in the media adapter and/or expansion slots in the hub. a. Remove the filler panel from the slot. For instructions on removing filler panels, see “Installing and Removing Filler Panels” later in this chapter.
C H A P T E R 2 Installi ng and Removing the Express Hub 17 Installing Multiple Hubs This section describes building a stack of Express hubs. Included in this section are the guidelines for stacking and cascading Express hubs and the physical requirements for installing multiple hubs.
C H A P T E R 2 Intel Express 100BASE-TX St ackable Hub 18 Mounting Requirements for Installing Multiple Hubs Position the hub you want to be numbered 1 at the top of the stack. When an NMM is installed in the stack, it assigns unit numbers starting from the top of the stack.
C H A P T E R 2 Installi ng and Removing the Express Hub 19 Installing and Connecting Multiple Hubs The procedure for installing and connecting multiple hubs is similar for rack installations and table or shelf installations. When installing multiple hubs, follow this sequence: • Install the hubs.
C H A P T E R 2 Intel Express 100BASE-TX St ackable Hub 20 d. Tighten the screw locks on the cable connectors to secure the plug to the hub. e. Repeat steps a through d for all the hubs in the stack. 3. Connect the power cords to the AC power receptacles on the rear panel of all the hubs in the stack.
C H A P T E R 2 Installi ng and Removing the Express Hub 21 For hubs that are mounted on a rack, you may have to remove the inoperable hub from the stack and move the adjacent hub up one rack mounting space, or install a replacement hub in the rack, before connecting the cascade cable to the new hub.
C H A P T E R 2 Intel Express 100BASE-TX St ackable Hub 22 To remove a filler panel, loosen the screws on the front of the filler panel, grasp the tab on the front of the panel, and pull the filler panel out of the slot. 5914 Technology by Bay Networks Intel 100BASE Removing a filler panel To install a filler panel, follow these steps: 1.
23 Physical Configuration Guidelines This chapter describes • Making connections to ports on the Express hub. • Verifying the installation. • The unit numbering convention.
C H A P T E R 3 Intel Express 100BASE-TX St ackable Hub 24 Network Configuration Decisions Before connecting your network devices to the ports on the Express hub, make sure you have made the following network configuration decisions: • Ensure that the new connections are within the simple Fast Ethernet repeater rules.
C H A P T E R 3 Physical Configurati on Guidelines 25 Connecting Cables to the Hub You can connect devices directly to ports on the Express hub, or to ports on installed media adapter and host modules. This illustration shows how to connect UTP or STP cable to RJ-45 connectors and fiber optic cable to SC connectors.
C H A P T E R 3 Intel Express 100BASE-TX St ackable Hub 26 Verifying Installation After you complete all port and power connections to the Express hub, verify that the installation is successful by observing the LEDs on the front panel of the hub.
C H A P T E R 3 Physical Configurati on Guidelines 27 • If an optional module is installed in the expansion slot, the Expansion Slot Stat LED lights green to indicate the module in the expansion slot has passed the confidence test and is operating normally.
C H A P T E R 3 Intel Express 100BASE-TX St ackable Hub 28 Unit Numbering Convention This section provides information about the hub unit numbering convention. The unit numbering convention is invoked when an NMM is installed in one of the Express hubs in a stack.
C H A P T E R 3 Physical Configurati on Guidelines 29 In a stack of four hubs, if you remove a hub that is assigned unit 2 and connect the cascade cable of unit 1 to unit 3, the hub that was assigned unit 3 will reset and be renumbered as unit 2.
C H A P T E R 3 Intel Express 100BASE-TX St ackable Hub 30 Connecting 100BASE-T Workstations to the Hub You can connect up to 12 workstations to 12 fixed ports with RJ-45 connectors on the Express hub, provided that the workstations are configured to operate at 100 Mbps (see “100 Mbps Network Devices” earlier in this chapter).
C H A P T E R 3 Physical Configurati on Guidelines 31 100BASE-T Switched LAN Integrating switching into the network enables network microsegmentation, which increases the total capacity and performance of the network. You can add 100 Mbps workgroups to the network and connect them to individual ports on the switch.
C H A P T E R 3 Intel Express 100BASE-TX St ackable Hub 32 By integrating the switching hub into the network that populates both 10 Mbps and 100 Mbps workstations, both groups experience the benefits .
