## Installing the Driver Software

The Gigabit Ethernet Controller must be physically installed in your system prior to installing the driver software.

| NOTE: A network device driver must be installed before the Gigabit Ethernet Controller can be used with your Windows NT system. BACS Help files require Internet Explorer 4.0 or later to work properly.

| NOTE: We recommend using Internet Explorer 5.0 to view help files.

Install the adapter software for Windows NT as follows:

1. Verify that the Windows NT system is upgraded with Service Pack 4 or later.

2. Start your Windows NT system and log on. You must have system administrator permissions to install the driver software.

3. Open the Control Panel.

4. In the Control Panel, double-click the Network icon.

5. When the Network window opens, select the Adapters tab.

6. Click Add to install a new adapter.

   All previously installed drivers are listed under Network Adapters.

7. When the Select Network Adapter window opens, click Have Disk....

8. When prompted, insert the driver installation media, or choose a location to install the driver from. Type the path to the driver, and click OK.

   For example, to install the adapter driver software for Windows NT, type e:\ in the Insert Disk location box (where e: is the designation of the CD-ROM drive on your system).

> | NOTE: If you acquired the adapter software on floppy disk, or from the Broadcom support website, enter the path to where the adapter driver files reside on your system.

9. With Gigabit Ethernet Controller highlighted in the Select OEM Option window, click OK.

> The adapter files are installed, then the Network window is displayed showing the newly installed adapter.

10. Click Close, then the Microsoft TCP/IP Properties window appears.

11. Configure the TCP/IP protocol and click OK.

12. When prompted to restart your computer, click Yes.

## Changing Configuration Parameters

After 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 Window

To configure adapter parameters, first bring up the Gigabit Ethernet Controller parameters window 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 and Duplex
> - Flow Control

> Refer to the parameter settings below for configuration details.

### Speed and Duplex Parameter

The Speed and 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 below:

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

| NOTES: Selecting the Auto setting 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 1 Gbps 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 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

### 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.

## Updating the Driver Software

Do the following to replace version 4.0 adapter driver software with newer versions as they become available.

1. Start your Windows NT system and log on. You must have Network Administrator permissions to install the driver software.
2. Open the Control Panel and double-click the Network icon.
3. When the Network window opens, select the Adapters tab. Any previously installed Gigabit Ethernet driver software is listed under Network Adapters.
4. Select a Broadcom Gigabit Ethernet Controller and click Update.
5. When the Select Network Adapter window opens, click Have Disk....
6. When prompted, insert the Broadcom CD-ROM into your system's CD-ROM drive, type the root path to the drive, and click Continue.

   For example, type e:\

   (Where e: is the designation of the CD-ROM drive on your system).

   The system then copies the appropriate adapter files from the CD-ROM.

| NOTE: If you acquired the adapter software on floppy disk, or from the Broadcom support website, enter the path to where the adapter driver files reside on your system.

1. When the copying process is complete, click Close in the Network window.
2. When prompted to restart your computer, click Yes. The system restarts using the new configuration settings.
