## Changing Configuration Parameters

Once the adapter driver software has been installed, you can examine and change the configuration options at any time. The following adapter parameters are user-configurable:

- Basic properties: Tx and Rx Flow Control, Duplex Mode, and Port Speed
- Optional properties: Failover Team Configuration and VLAN Configuration

### Gigabit Ethernet Controller Parameters Screen

To configure adapter parameters, first bring up the Gigabit Ethernet Controller parameters screen as follows:

1. Open the Control Panel and right-click the Network icon.
2. When the Network window opens, select the Adapters tab.

> The bus and slot numbers of the highlighted adapter are listed as part of the adapter name in the Network Adapter window.

3. Select the desired adapter from the Network Adapters window and click on Properties. The Gigabit Ethernet Controller parameters window opens.

> The possible adapter parameter types are:

> - Speed & Duplex
> - Flow Control
> - Jumbo Mtu

> Refer to the parameter settings below for configuration details.

### Speed & Duplex Parameter

The Speed & Duplex parameter allows the user to set the connection speed duplexed to the network. Note that Duplex Mode allows the adapter to transmit and receive network data simultaneously. The adapter is set to Auto (optimum connection) by default. Set the speed and mode as described and shown below:

- Auto - (Default) Sets the speed and mode for optimum network connection (recommended)
- 10 Mb Half - Sets the speed at 10Mbps and mode to Half Duplex
- 10 Mb Full - Sets the speed at 10Mbps and mode to Full Duplex
- 100 Mb Half - Sets the speed at 100Mbps and mode to Half Duplex
- 100 Mb Full - Sets the speed at 100Mbps and mode to Full Duplex

  ###

| NOTES – Auto is the recommended selection. This selection allows the adapter to dynamically detect the line speed and duplex mode of the network. Whenever the network capability changes, the adapter will automatically detect and adjust to the new line speed and duplex mode. Also, when Auto is selected, the 1Gbps speed detection is enabled.

### Flow Control Parameter

The Flow Control parameter allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The recommended selection is Disable, which will configure the adapter to ignore PAUSE frames. Disabled by default, to enable Flow Control to receive, transmit, or receive and transmit PAUSE frames, select the appropriate parameter from the drop-down menu described and shown below.

- Disable - (default) PAUSE frame receipt and transmission is disabled (recommended)
- Rx PAUSE - PAUSE frame receipt is enabled
- Tx PAUSE - PAUSE frame transmission is enabled
- Rx/Tx PAUSE - PAUSE frame receipt and transmission is enabled
- Auto - PAUSE frame receipt and transmission is optimized

> ###

### Jumbo Mtu Parameter

The Jumbo Mtu parameter allows the adapter to transmit and receive oversized Ethernet frames that are greater than 1514 but less than 9000 bytes in length. Note that this parameter will require a switch that is able to process large frames.

Set at 1500 bytes by default, to increase the size of the received frames, select the byte quantity in 500-byte increments from the drop-down menu shown below.

### Save Settings

1. When adapter parameter configuration is complete, click Continue at the Gigabit Ethernet Controller screen to accept the settings..
2. When prompted to restart your computer, click Yes.

> The system restarts, using the new configuration settings.

3. When the system returns to proper operation, verify that the adapter port LEDs operate as described in Table 1 in the Introduction.

| NOTE - If no configuration changes have been made, you can click No to close the configuration session without restarting your system.

| NOTE – If other adapters in your system use TCP/IP bindings, the TCP/IP Properties window opens. Perform any necessary TCP/IP configuration and click OK when finished. For help in configuring TCP/IP protocol, consult your Microsoft Windows NT 4.0 documentation.
