4 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 .
5 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.
6 Connection Guidelines General • The 140T is capable of autonegotiating port speed and can operate at 10Mbps or 100Mbps per port. The hub matches the highest possible speed of an attached device. • The ports on the 140T hub are half-duplex. The hub cannot connect to a device at full-duplex.
7 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.
8 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 CA T 5 UTP cabling to operate at 100Mbps.
9 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.
10 Can I daisy-chain a 100Mbps hub to the 140T hub with UTP cabling? Y es. The 140T is a Class II device so you can daisy-chain two hubs operating at 100Mbps a maximum of 5m.
