The Intelligent Way to Connect
The Intel
®
82572EI Gigabit Ethernet Controller is
a single, compact component with fully integrated
Gigabit Ethernet Media Access Control (MAC) and
physical layer (PHY) functions. This device uses
the PCI Express architecture (Rev. 1.0a), and
also enables a Gigabit Ethernet implementation
in a very small area, which is useful for server
and workstation network designs with critical
space constraints. The Intel 82572EI Gigabit
Ethernet Controller provides an IEEE 802.3*
Ethernet interface for 1000BASE-T, 100BASE-TX,
and 10BASE-T applications. It also integrates
a Serializer-Deserializer (SerDes) to support
1000BASE-SX or 1000BASE-LX (optical fiber)
and Gigabit backplane applications. In addition
to managing MAC and PHY Ethernet layer
functions, the controller manages PCI Express
packet traffic across its transaction, link, and
physical/logical layers.
On-Board Management Features
The on-board System Management Bus (SMB)
or Fast Management Link (FML) ports of the
Intel 82572EI Gigabit Ethernet Controller enable
network manageability implementations required
by IT personnel for remote control and for alerting
via the LAN. With SMB, management network
packets can be routed to or from a management
processor. The SMB port enables industry
standards, such as the Intelligent Platform
Management Interface (IPMI) and Alert Standard
Format (ASF) 2.0, to be implemented using the
controller. In addition, connecting to a manage-
ment processor via the controller’s FML port
allows higher speed management traffic, such
as keyboard, video and mouse (KVM) data, to
be sent via the LAN to a remote management
console. Both SMB and FML operation use the
standard SMB protocol and allow enhanced
pass-through implementations using a
standardized interface.
