Testing the adapter
Test the adapter by running Intel diagnostics. For Windows 95/98/2000 and Windows
NT run Intel PROSet by double-clicking the Intel PROSet Icon in the Control Panel.
Click Help from the main PROSet window to get complete diagnostics information and
instructions.
Ethernet Technical Information
Fast Ethernet Wiring
100BASE-TX Specification: The 100BASE-TX specification supports 100Mbps
transmission over two pairs of category 5 twisted-pair Ethernet (TPE) wiring. One pair
is for transmit operations and the other for receive operations. Segment lengths are
limited to 100 meters with 100BASE-TX for signal timing reasons. This complies with
the EIA-568 wiring standard.
Fast Ethernet Hub and Switches
The two basic types of hubs are shared hubs and switching hubs. Intel PRO/100+
adapters can be used with either type of hub for 10Mbps. At 100Mbps, a TX hub or
switch is required.
Shared hubs
In a shared network environment, computers are connected to hubs called repeaters. All
ports of the repeater hub share a fixed amount of bandwidth, or data capacity. On a
100Mbps shared hub, all nodes on the hub must share the 100Mbps of bandwidth. As
stations are added to the hub, the effective band-width available to any individual
station gets smaller. Shared hubs do not support full duplex. Think of a shared repeater
hub as a single-lane highway that everyone shares. As the number of vehicles on the
highway increases, the traffic becomes congested and transit time increases for
individual cars.
