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 Activity Port Activity Orange = Autodisabled... -
Page 7: 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 100Mbps Standalone Hub... -
Page 8: Connecting To Devices
A bridge allows two segments to communicate with each other. Typically, a bridge connects segments operating at different speeds. The 140T contains an internal bridge that automatically allows devices operating at 10Mbps to communicate with devices operating at 100Mbps. ® Intel Express 140T Collisions Power 10Mbps 100Mbps Standalone Hub... -

When using the daisy-chain port, follow these guidelines: • Only two hubs (ClassII) can be daisy-chained together. • The maximum cable length connecting the hubs can’t exceed 5 meters. 100m (max) 5m (max) 100m (max) Intel ® Express 140T Collisions Intel ® Express 140T Collisions Power 10Mbps... -
Page 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. - Page 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.

Page 12: Troubleshooting
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 to communicate with each other automatically. -
