Flow Control

AT-29xx Series Gigabit Ethernet Network Adapters Installation Guide

The Ethernet@Wirespeed property enables a Gigabit Ethernet adapter to establish a link at a lower speed when only two pairs of wires are available in the cabling plant. This property is available on the AT-2972/T2 adapter only. By default, the Ethernet@Wirespeed property is enabled.

To change the Ethernet@Wirespeed property, perform the following procedure:

1.For Windows Server 2003 and Windows XP systems, access the System Properties Dialog Box. See “Modifying Configuration Properties” on page 39.

For Windows 2008 R2, Windows 7, and Windows Vista systems, access the Device Manger for your operating system:

ˆTo access the Device Manager window in Windows 2008 R2 or Windows 7, see “Selecting the Device Manager in Windows 2008 R2 and Windows 7” on page 44.

ˆTo access the Windows Vista Device Manager, see “Selecting the Device Manager in Windows Vista” on page 46.

2.Click the Advanced tab.

The Advanced tab is shown in Figure 21 on page 56.

3.From the Properties list, select Ethernet@Wirespeed.

4.From the Values list, select one of the following:

ˆEnable - Enables Ethernet@Wirespeed. This is the default.

ˆDisable - Disables Ethernet@Wirespeed.

5.Click OK.

6.If prompted to restart your computer, click Yes.

Although it is not necessary to reboot the system for new adapter properties to take effect, rebooting is recommended to reinitialize all registers.

7.Verify that the adapter port LEDs operate as described in “LEDs” on page 18.

The Flow Control property allows you to enable or disable the receipt or transmission of PAUSE frames which allow the adapter and the switch to control the transmit rate. The port side that receives the PAUSE frame momentarily stops transmitting. The recommended selection is Disable, which configures the adapter to ignore PAUSE frames. By default, the Flow Control property is disabled.
