Description
===========
The Compaq NC3123 NIC uses a PCI v2.1/v2.2 bus architecture with the Intel
82559 chipset. The NIC supports emerging standards for system manageability
and power management, such as ACPI and PC98. The Compaq NC3123 NIC has one
RJ-45 port and auto-negotiates 10 or 100 Mb/s, depending on the speed of the
device to which it is connected. Performance is further ensured with a 6 KB
buffer memory which makes for low CPU utilization at high throughputs.
The NC3123 features a robust plug and play capability for conflict-free auto
configuration. Auto-sensing capabilities enable the NC3123 to automatically
negotiate between 10 and 100 Mbps to achieve the highest common speed on the
network. Compaq's SmartStart configuration utility includes setup support
for the NC3123 so the NIC can be configured easily in server environments.
The Wake on LAN feature lets designers build NICs that can "listen to"
network activity even when the computer is turned off. WOL NICs have a
special low-power standby mode that is active when the rest of the computer
is without power. The NIC will respond to a special "wake-up" packet sent by
another computer or network device. Typically this wake-up packet causes the
NIC to signal the computer to power up. For the Wake on LAN (WOL) feature to
work correctly, the NC3123 NIC must be connected to a continuous power
source. This allows the NIC to listen to the network even when the computer
is turned off.
Along with Wake on LAN, the NC3123 also provides standard SNMP MIB support
and can be remotely monitored with Compaq Network Management Software
(CNMS), Compaq Insight Manager, or any SNMP-compliant management software.
Supports DMI 2.0 (Desktop Management Interface) for inventory control and
asset management. Supports Web-Based Enterprise Management (WBEM)
The PCI Hot Plug capability enables PCI networking controllers to be
replaced or added to a server without taking the system down.
Network Fault Tolerance (NFT) is a simple, effective, and fail-safe approach
to increase the reliability of server connections. NFT gives you the ability
to set up link recovery to the server NIC in case of a cable, port, or NIC
failure. By assigning two Compaq NICs as a team, NFT enables you to maintain
uninterrupted network performance. During normal operation, the backup will
have transmit disabled. If the link to the primary NIC fails, the link to
the backup NIC automatically takes over.
Adaptive Load Balancing (ALB) creates a team of NICs to increase a server's
transmission throughput. ALF works with any 100Base-TX or Gigabit switch.
With ALB, as NICs are added to the server, you can group them in teams to
provide a single virtual NIC with increased transmission bandwidth. For
example, an ALB team containing four Compaq Fast Ethernet NICs configured
for full-duplex operation can provide an aggregate, maximum transmit rate of
400 Mb/s and a 100 Mb/s receive rate. In this example, total bandwidth is
500 Mb/s. To use ALB, you must install at least two Compaq NICs in the
server and link these to the same network hub/switch.
Features
========
Half- and full-duplex operation. Full Duplex at 20Mbps for
Ethernet, 200Mbps for Fast Ethernet.
6 KB of buffer memory, FIFO.
Automatically senses 10 and 100Mbps. Auto-negotiation (hardware
and software implementations)
Network Fault Tolerance capability when configured with a 2nd
NIC.
PCI Hot Plug compatible.
WOL, Wake On LAN using 3-pin header or through the PCI Bus.
AOL, Alert On LAN support.
ALB, Adaptive Load Balancing. and Cisco's Fast EtherChannel are
two port bonding methods supported by the NC3123. ALB provides both
failover and balancing of transmit traffic across NICs for increased
performance.

One RJ-45 port operating at 10 or 100 Mb/s
64/32-bit , 33 Mhz PCI host-interface compliant
ACPI and PC98 compliant
Built-in Compaq Network Teaming and Configuration (CPQNTAC)
utility provides NIC teaming, diagnostics, and statistics for Windows NT
4.0 users and diagnostics and statistics for Windows NT 3.51 users.
Windows 95 users can access CPQSET, a utility providing diagnostics and
statistics.
