2 NIC Overview 3CR990 NICS The 3CR990 network interface cards (NICs) represent a new generation of secure, intelligent client NICs with an on-board RISC processor (3XP processor). The RISC processor is designed to optimize system and network performance. Optimization occurs by offloading key networking and security tasks even when running bandwidth-intensive applications such as voice, video, imaging, and Internet and intranet applications.
CHAPTER 2: 3CR990 NICS The following figure shows the 3CR990 NIC and the location of its major components.
NIC Features 17 MBA preboot support allows you to use management applications to perform tasks such as: ■ Installing and configuring a new PC that has never been connected to the network. ■ Upgrading software. ■ Scanning for viruses. ■ Performing disaster recovery tasks. In addition to firmware, MBA has a complete set of tools, utilities, and pre-OS software that enables network administrators to perform tasks such as: ■ Reconfiguring multiple systems at once.
CHAPTER 2: 3CR990 NICS Desktop Management Interface Desktop Management Interface (DMI) is a network management standard that is widely accepted for managing Intel-based computers. The 3Com DMI Agent allows any DMI management application to access information such as the NIC driver location, version, and size; packets sent statistics; crc receive errors; and much more.
Windows 2000 Offload Features Enabling Offloads 19 Windows 2000 provides the capability to individually enable or disable each of the four offload features. (The default setting for these features is enabled.) NOTE: For users running the Beta 3 version of Microsoft Windows 2000, the Offload function must be globally enabled in Windows 2000 before individual offload features can be enabled or disabled. See the readme.

A NIC Specifications SPECIFICATIONS The following table provides environmental, interface, and standards information for the EtherLink 10/100 PCI network interface cards with 3XP processor (3CR990 family). Hardware Memory 128 K external RAM Bus interface PCI Local Bus Specification, Revision 2.2 32-bit bus PCI master Supports bus master scatter-gather DMAs. Dimensions Length:5.24 in/13.31 cm Width: 3.35 in/8.51 cm Power requirement +5 V ±5% operating 1.
APPENDIX A: SPECIFICATIONS Network Connection Criteria The following table provides network connection criteria for the 3CR990 NICs.
Network Cable 67 The 10BASE-T name indicates a signaling speed of 10 Mbps and twisted-pair wiring. Base stands for baseband, which denotes a technique for transmitting signals as direct-current pulses rather than modulating them onto separate carrier frequencies. A wiring topology using 10BASE-T specifies a wiring hub, cable arranged in a star configuration, and unshielded twisted-pair cable. Each node has a separate cable run that must not exceed 328 ft. (100 meters) from the node to the hub.
APPENDIX A: SPECIFICATIONS Flow Control Pause Frames The 3CR990 NICs utilize flow control technology to throttle the incoming data packet stream and prevent the loss of packets. IEEE 803.2x flow control prevents the input buffers of a device from overflowing. By using pause frames to communicate buffer status between linked transmitting and receiving devices (transmitters and receivers).
