50-60 Hz 1.5A MAX. Power Plug • Autosenses speed—10Mbps or 100Mbps per port. • Automatically bridges 10Mbps and 100Mbps segments. • Can be daisy-chained with another 140T hub (or any ClassII hub) to expand port density (maximum of two hubs). -
Página 6: Understanding 140T Hubs
Understanding 140T Hubs Port LEDs On the 140T, the port LEDs are located on a common panel with the hub LEDs. These LEDs indicate port status, individual port speed, and port activity. Solid green = Link Top rows: Port Blinking green = Activity... -
Página 7: Hub Leds
Hub LEDs The 140T hub LEDs are located above and below the port LEDs. These LEDs indicate the condition of the power supply, collisions per segment, and the amount of traffic per segment. ® Intel Express 140T Collisions Power 10Mbps... -
Página 8: Connecting To Devices
• The ports on the 140T hub are half-duplex. The hub cannot connect to a device at full-duplex. • To prevent a loop in the network, do not connect the 140T to 10Mbps and 100Mbps segments simultaneously if the 10Mbps and 100Mbps segments are bridged externally (through a switch). -
Página 9: Daisy-Chaining Hubs
Normally, to make a hub-to-hub connection you need to use a crossover cable. The daisy-chain port on the 140T hub is wired MDI so you can use a straight-through cable to connect the 140T to an MDI-X port on a hub or switch. -
Página 10: Cabling Devices
Cabling Devices Media Requirements Incorrect cabling is often the cause of network configuration problems. Read the next two pages if you’re unsure of your requirements. 100Base-TX The 100Base-TX Fast Ethernet specification requires that you use CAT 5 UTP cabling to operate at 100Mbps. If you use lower grade cabling (CAT 3 or CAT 4), you may get a connection, but will soon experience data loss or slow performance. - Página 11 However, if the LEDs remain off, you probably have a bad cable. If a cable passes either of these tests, but the network connection is slow, verify that wires 1 & 2 and 3 & 6 on the cable are twisted pairs. Refer to the following diagrams.

Página 12: Troubleshooting
Can I daisy-chain a 100Mbps hub to the 140T hub with UTP cabling? Yes. The 140T is a Class II device so you can daisy-chain two hubs operating at 100Mbps a maximum of 5m. How do I get devices running at 10Mbps to talk to devices running at 100Mbps? The 140T hub’s internal bridge allows 10Mbps and 100Mbps segments... -
