Connection Types
Here are some of the possible connection type options given when
configuring NICs. The options vary depending which operating
system the NIC is being configured on.
■ Autodetect Default Connection
Detects the cable type, optimal line speed, and duplexity for
the specific Adaptec PCI NIC model in use. This is the default
and recommended connection type.
■ 10 Mbps UTP/Half Duplex
Forces the connection to 10 Mbps in Half Duplex mode.
■ 100 Mbps TX/Half Duplex
Forces the connection to 100 Mbps in Half Duplex mode.
■ 10 Mbps UTP/Full Duplex
Forces the connection to 10 Mbps in Full Duplex mode.
■ 100 MbpsTX/Full Duplex
Forces the connection to 100 Mbps in Full Duplex mode.
Full Duplex Support
To implement Full Duplex on your network, you need both a NIC
and a switch that supports Full Duplex. Full Duplex support allows
a NIC to send and receive data at the same time, doubling available
bandwidth.
Note: Full Duplex can also be enabled point-to-point with a
crossover cable instead of a switch.
Installation instructions in this user’s guide describe how to enable
Full Duplex. Additional information can be found in the
readme.txt
files. Adaptec PCI TX NICs support Full Duplex at both 10 Mbps
and 100 Mbps.
