Configuring the 100/10 PCI Ethernet Adapter
Configuring for Full-Duplex
If you have a hub that does not support auto-negotiation, manually
configure the adapter for full-duplex support. Configuration is
specific to the driver that you are loading for your network
operating system. Refer to Table 1.
Note: You must set the adapter speed when configuring for
full-duplex support. Do not leave the speed set to
auto-negotiate.

Fast Ethernet Cabling
The 100BASE-TX specifications support 100 Mbps transmission over
two or four pairs of twisted-pair Ethernet cabling. In two pair
cabling, one pair of cables is used for transmission, and the second
is used for reception and collision detection.
Because a 125 MHz frequency is used on the wire, 100BASE-TX uses
Category 5 cabling.
Segment lengths are limited to 100 meters (328 feet) with
100BASE-TX for signal timing reasons.
Fast Ethernet Hubs
New hubs are available to support a variety of Fast Ethernet LAN
configurations. These hubs can be divided into two basic types:
shared and switched. 100/10 PCI Ethernet adapters can be used
with either type of hub for 10 Mbps or 100 Mbps operations.
