3CR990-FX-97 NIC Features

 

Offload Features

 

The 3CR990-FX-97 NIC supports Windows 2000 and Windows XP offload features in an

 

IP environment. The Windows offload features are designed to enhance the operating

 

system capabilities by off-loading key TCP/IP networking and security tasks from the

 

operating system:

 

 

NIC Offload Features

Description

 

 

IPSec Offload

Reduces CPU utilization by allowing the 3XP processor and a crypto chip on the NIC to

 

perform data encryption operations.

 

 

TCP Segmentation Offload

Reduces CPU utilization by allowing the 3XP processor on the NIC to perform segmentation

 

of TCP packets.

NOTE: Windows 2000 does not allow IPSec offloads and TCP Segmentation offloads for the same session. Though all offload types may be enabled, TCP Segmentation offloading does not occur during an IPSec session.

IP and TCP Checksum Offload

Reduces CPU utilization by allowing the 3XP processor on the NIC to perform the checksum

 

calculation of TCP/IP and UDP/IP packets.

 

 

802.1P Packet Priority Offload

Reduces CPU utilization by allowing the 3XP processor on the NIC to perform the insertion of

 

the 802.1Q tag header into the packet.

 

 

For more information on enabling and disabling offloads for Windows 2000, see

Chapter 4, “Using Windows Offload Features.”

Remote Wake-Up

Remote Wake-Up provides the ability to remotely power-on a network computer for after- hours administration. When the PC is in sleep mode (standby state) and receives a wake- up packet (Magic Packet frame) through the LAN, the NIC turns on the power to the PC. Remote Wake-Up also requires using a desktop management application that is able to generate a Magic Packet Remote Wake-Up signal.

If the computer complies with PCI 2.2, Remote Wake-Up is automatically enabled through the PCI bus.

NOTE: The 3CR990-FX-97 NIC supports only STANDBY state.

Remote Wake-Up Requirements

The following conditions are required to use Remote Wake-Up: Management application that supports Remote Wake-Up BIOS that supports Remote Wake-Up

PCI 2.2-compliant bus and a 5-volt standby power supply unit rated at a minimum of 375 milliamperes

If you are unsure whether your computer meets the requirements listed above, refer to the computer documentation or consult the computer manufacturer.

Remote Wake-Up and Multiple NIC Installations

To use multiple NICs as Remote Wake-Up NICs in the same computer, the computer must have a power supply that can support multiple Remote Wake-Up devices.

Refer to your computer documentation if you are unsure whether your computer power supply can accommodate more than one Remote Wake-Up device.
