1 Quick Start 1. Install the Express 10/100 Stackable Hub in a rack or on a shelf or table, plug it in, and turn the power on. 2. Connect either 100BASE-TX devices or 10BASE-T devices to the ports. 3. Check the LEDs for links. You’re done. Next steps (Optional) Continue to the next page if you want to connect multiple hubs.
2 (Optional) Connecting multiple hubs Connecting hubs running at 100 Mbps to hubs running at 10 Mbps Use an Intel Cascade Cable to connect the hubs. Hubs running at 100 Mbps can talk to each other, and hubs running at 10 Mbps can talk to each other.
3 3 Over view This guide covers both the 12- and 24-port versions of the Intel Express 10/100 Stackable Hub. • Intel product code: EE110TX12 • Intel product code: EE110TX24 • 12 fixed TPE ports .
4 Connection Guidelines Connecting 100BASE-TX devices • Use Category 5 twisted-pair Ethernet (CAT 5 TPE) cable. • Always limit the distance between devices connected with TPE cable to 100 meters (the IEEE specification requires this). • Use a crossover cable to connect the hub to a switch.
5 Example Configurations Mix ed 10 Mbps and 100 Mbps en vir onment A stack of Express 10/100 Stackable Hubs can contain hubs running at both 10 and 100 Mbps. However, the hubs running at 10 Mbps and the hubs running at 100 Mbps are on separate network segments.
6 Bridging with the Express 10/100 Fast Ethernet Switch A switch with individual ports capable of operating at 10 or 100 Mbps can bridge 10 Mbps and 100 Mbps segments. No configuration of your network operating system is needed. Express 10/100 Fast Ethernet Switch Category 5 TPE (100m max.
7 Bridging with the Express 10/100 Downlink The Express 10/100 Downlink has two ports that operate at either 10 or 100 Mbps. Each port automatically senses the speed of the attached device. All you need to do is set the speed of the hubs. No configuration of your network operating system is needed.
8 Extending the 100 Mbps network topology You can extend the network topology only by connecting hubs to a switch, bridge, or router. You can’t extend the topology by daisy- chaining hubs together. In the example below, the network diameter is extended to 400 meters by connecting the two hub stacks to an Intel Express 10/100 Fast Ethernet Switch.
9 Extending the 10 Mbps network topology To extend the 10BASE-T network topology, you can attach hubs to a switch or daisy-chain the hubs using TPE cabling.
10 Understanding LEDs P or t LEDs The LEDs above a port provide information about the port’s configuration and status. Green LED (left side) Amber LED (right side) LED Status Meaning Green Solid Port has a link. Blinking Receive activity detected on port.
11 Unit LEDs Unit LEDs indicate the status of a hub’s power supply, hub speed, collision occurrences in a hub or stack of hubs, and whether a hub is managed. 10BASE-T 100BASE-TX Collision Managed Status Power Change hub speed LED Status Meaning 10BASE-T O n Hub is operating at 10 Mbps.
12 Cab ling Requirements Incorrect cabling is often the cause of network problems. Read the next two pages if you’re unsure of your requirements. 100B ASE-TX requirements The 100BASE-TX Fast Etherne.
13 Straight-thr ough vs. c r osso ver cab les Ports on the hub are wired MDI-X (media dependent interface crossover) so you can use a straight-through cable when connecting to a workstation or server (network adapter cards are wired MDI). For direct connection to another MDI-X port (hub and switch ports), you must use a crossover cable.
14 T r oubleshooting No link (green LED is off). • Remove the cable and plug it in again. Wait up to six seconds for a link. • If you’re using the wrong type of cable, either straight-through or crossover, the green LED above the port will not come on.
15 Frequently Asked Questions I have 10 Mbps and 100 Mbps hubs connected with an Intel Cascade Cable. Can they talk to each other? No. All hubs running at 100 Mbps are in one collision domain (or segment) and all hubs running at 10 Mbps are in a separate collision domain.
16 Can I configure a full-duplex link between the hub and another device? Only to the optional Ethernet Module or Fiber Module. The external ports on the modules are switched ports and are capable of full duplex. The base ports of the hubs aren’t capable of full-duplex operation.
