Description
===========
The NC3122 Dual Port Fast Ethernet NIC provides a low cost dual port
solution for workgroups to high-end servers that require redundancy and high
performance. This Network Interface Controller is a high performance
Ethernet LAN adapter with two fully integrated 10BASE-T/100BASE-TX LAN 82558
controllers connected on the secondary PCI bus of the 21152 PCI-to-PCI
bridge. The 82558 Ethernet controller consists of both the MAC controller
and the 10/100 Mbps physical layer interface. The controller also supports
emerging standards for system manageability and power management, such as
ACPI. The 21152 bridge chip complies fully with Revision 2.1 of the PCI
Local Bus Specification and Revision 1.1 of the PCI-to-PCI Bridge
Architecture Specification.
The 82558 based Compaq NC3122 Dual Fast Ethernet Controller is a
sophisticated 32-bit PCI component with enhanced scatter-gather bus
mastering capabilities. Its true 32-bit architecture enables it to perform
high-speed data transfers on the PCI bus using four DMA channels. The 82558
Compaq NC3122 Dual Fast Ethernet Controller provides full support for both
half duplex and full duplex operation, as well as support for full duplex
flow control on both ports.
Features
========
Plug and Play for easy installation
PCI Hot Plug capable--enables NICs to be replaced or added to a
PCI Hot Plug compatible server without having to take the system down.
Automatically senses and configures to the highest possible
network connection speed (10 or 100 Mb/s)
Auto-negotiates between half- and full-duplex Ethernet or Fast
Ethernet
Network Fault Tolerance--enables the NIC to keep an active
connection if a switch or hub link fails by automatically switching to a
secondary NIC or port.
Support for Adaptive Load Balancing, which allows full-duplex
ports to be grouped together (up to four ports) to increase available
bandwidth
Support for the Cisco Fast EtherChannel, which provides high
performance port bonding (up to four) and port fail-over coverage.
*Note:* Cisco Fast EtherChannel works only in Cisco Fast EtherChannel
switches, such as the Catalyst 5000.
Bus-mastering technology to maximize throughput and minimize CPU
utilization
Both ports are IEEE 802.3/802.3u 10BASE-T and 100BASE-TX
compatible
Glueless 32-bit PCI bus master interface via the 21152 bridge
chip
82557-Style Chained Memory Structure streamlined for performance
enhancement
Backwards compatible with 82557 software
Internal transmit and receive FIFOs (3 Kbytes each)
Back-to-back transmit at 100 Mbps within minimum IFS
EEPROM support for configuration and customization feature
section
Integrated 100BASE-TX PHY and 10BASE-T Serial ENDEC
(Encoder/Decoder) and transceiver with built in transmit and receive
filters
10BASE-T and 100BASE-TX capability using a single RJ-45
connector for each port
Both ports support IEEE 802.3u Auto-Negotiation for 10BASE-T and
100BASE-TX
Both ports support IEEE 802.3u Auto-Negotiation for hardware
selection of highest operating speed
Full or half duplex capable at 10 or 100 Mbps on both ports
IEEE 802.3x flow control support
Bay Technologies flow control support with the internal
100BASE-TX PHY
Supports ACPI rev 1.0, PC98 and PCI Power Management Spec.
Supports wakeup events in the following power states: D0a, D1,
D2, and D3(hot)
Does not support wakeup events in D3(cold)
Wakeup events are signaled to the system through the PME# pin on
the PCI bus connector
Supports the following wakeup events in the Bus States as shown:
Individual Address match B0, B1, B2
Multicast Address match B0, B1, B2
Link Status ChangeB0, B1, B2
ARP packet B0, B1, B2
Magic Packet B0, B1, B2
Flexible Packet Filtering B0, B1
