Chapter 1. Introduction
Thank you for choosing SMC9452TX-2 Gigabit PCI Ethernet Adapter.

1.1 Convention

The Adapter or SMC9452TX-2 mentioned in this User Guide stands for SMC9452TX-2 Gigabit
PCI Ethernet Adapter.

1.2 Product Overview

SMC9452TX-2 is a highly integrated and cost-effective single-chip Gigabit Ethernet Adapter that
provides 32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3
10Base-T, IEEE802.3u 100Base-TX and IEEE 802.3ab 1000Base-T specifications. It also
supports ACPI, PCI power management for modern operating systems that are capable of
Operating System Directed Power Management (OSPM) to achieve the most efficient power
management.
Through the aid of a VLAN membership, SMC9452TX-2 adheres to the 802.1Q for multiple VLAN
support, and 802.1P for packet prioritization. With 802.1Q support, server resources can be
shared with multiple VLANs when used in conjunction with any 802.1Q-enabled Switch. With the
802.1p support, SMC9452TX-2 allows a range of Ethernet packets to be prioritized from a critical
to a non-critical designation through a priority tag.
SMC9452TX-2 supports Full Duplex operations at 20/200/2000 Mbps data speeds used in
conjunction with 802.3x flow control support. With 802.3x flow control SMC9452TX-2 uses both
asymmetric and symmetric functions via the MAC control pause function. Any participating 802.3x
flow control node can be controlled by initiating a pause control to stop incoming network traffic, to
further reduce network congestion. SMC9452TX-2 also supports the WOL (Wake on LAN)
Function which allows a remote station “wake” your computer when it is in Standby or Hibernate
mode or after shutdown.
By default SMC9452TX-2 supports the standard 1518 Byte frame size. In addition, SMC9452TX-2
also supports Jumbo Frame transmission
It includes an interface for a boot ROM and can be used in diskless workstations, providing
maximum network security and ease of management.
In addition, being PCI 2.2 compliant, SMC9452TX-2 works with 32-bit 33Mhz PCI busses. This
compatibility provides users with an easy migration path to increase performance between
servers and workstations for large file transfer, video editing and server clustering for data
intensive applications.
