Intel 140T User Manual

• 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.

• 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).

•  Use Category 5 unshielded twisted-pair (CAT 5 UTP) cable when

connecting 100Mbps devices to the hub.

•  Use Category 3, 4, or 5 unshielded twisted-pair (CAT 3, 4, 5 UTP)

cable when connecting 10Mbps devices to the hub.

•  Limit the cable length between devices to 100 meters.

•  Use crossover cables or the daisy-chain port to connect to a hub

or switch.

• Use a straight-through cable to connect the hub to a server or

workstation. For more information on cabling, see pages 8-9.

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.
