Installation

Unpack and Inspect

CAUTION: Under ordinary circumstances, the DXE-810T card will not be affected by static discharge caused by

contact with a person’s body while handling the unit. In special circumstances, the user may carry an

extraordinarily high static charge so it is good practice to disperse the charge by touching a ground

before handling the adapter card.

Open the shipping carton and carefully remove all items. Ensure that the following items are included:

One DXE-810T PCI Express 10 Gigabit Ethernet Adapter Card

DXE-810T drivers and manual on a CD-ROM

If any of these items are missing or damaged, please contact your local reseller for a replacement.

Software Installation for Linux

1. Make clean

2. Sudo make

3. Sudo make install

4. Reboot the system

Software Installation for VMware ESXi 5.x, 6.0

1. Copy the VIB file (net-tn40xx-0.3.6.12.1.x86_64.vib) to the VMware server:

2. On the VMware server shell type:

esxcli software acceptance set --level CommunitySupported

esxcli software vib install -v /net-tn40xx-0.3.6.12.1.x86_64.vib

3. Reboot the VMware server

Software Installation

You must first install the driver software for your DXE-810T before installing the PCI Express card into your

PC. Insert the CD into your PC’s CD-ROM drive. The driver installation program will run automatically if you

have AutoPlay enabled.

If you do not have AutoPlay enabled for your PC’s CD-ROM drive, navigate to the root directory of the CD

drive using Windows Explorer and double-click Autorun.exe. In the new window, click the Install Driver link

to install the driver for the NIC.

The CD-ROM included with your DXE-810T is designed to make installing required software a painless and

trouble-free process. Simply click on the Install Drivers link, and an Installation Wizard will guide you through

the process, no matter which operating system you’re running. The included Adobe Acrobat Reader, which is

needed to read or print out your user manual, will also come in handy for many other applications.

Simply follow the directions in the wizard, and your DXE-810T will be installed successfully in just a few

minutes, allowing you to enjoy the many advantages of connecting to an Ethernet LAN.

After the driver installation program is complete, you can then power off your computer and install the PCI

Express card. Once you restart your PC, the DXE-810T will be ready to use.

Installing the Adapter

1. Shut down the computer, unplug its power cord, and remove the chassis cover.

(Important: Opening the case of your computer may compromise its warranty. Consult the computer

manufacturer before opening the case to ensure that you adhere to warranty guidelines. In some cases,

you may need to have the DXE-810T installed by your computer manufacturer’s service technician.)

2. Insert the contact edge of the DXE-810T card into the connector of any available PCI Express Bus

Master expansion slot. Press the card firmly into the connector such that the card’s contacts are fully

seated in the connector.

3. Install the bracket screw that secures the card to the computer chassis.

4. Reinstall the computer’s chassis cover.

5. Reconnect the computer’s power cord, and switch on the computer’s power.

Changing the Link Speed Manually

1. Windows:

User can choose speed values in Advanced Properties as shown below.

2. Linux:

User can change link speed using the “ethtool” command, for example:

Force 10G: “ethtool –s <ethxx> speed 10000 autoneg off”

Force 5G: “ethtool –s <ethxx> speed 5000 autoneg off”

Force 2.5G: “ethtool –s <ethxx> speed 2500 autoneg off”

Force 1G: “ethtool –s <ethxx> speed 1000 autoneg off”

Force 100M: “ethtool –s <ethxx> speed 100 autoneg off”

Auto-Negotiation: “ethtool –s <ethxx> autoneg on”

Troubleshooting

If you experience any problems with the adapter, check:

that the appropriate driver is loaded;

that the proper grade of cable is used for the network connection;

that the supporting hub is qualified for the application.

Optimized Performance Tuning

This section describes possible systems and OS configuration options for general users to achieve the best

performance in typical LAN environments with normal traffic.

Preinstalled Systems

The technical information in this section and beyond targets newly installed systems. Normally, on a system

that meets our recommended minimum hardware requirements and a freshly installed OS, full throughput

performance is expected.

However, existing systems which are already in use and have had hardware and software changes may

experience lower than maximum network throughput. In this section we will provide some examples, places

to check, and tips that may help improve performance in such cases.

Check if the currently installed hardware meets our “Recommended Hardware” list:

Verify that latest BIOS version is loaded and “Optimized Defaults” are used.

Make sure the memory DIMMs match the recommended speed and are installed correctly.

If supported by your motherboard, using faster memory may improve performance.

High CPU usage may degrade traffic performance:

Check if the specific cores being used by the NIC for traffic processing are also used by other

processes.

D-Link Network Driver includes a CPU load balancing mechanism with optional configurations. The

system administrator may change the CPU working cores assigned to the NIC to allow higher

throughput.

User should check if there are any other network applications that may degrade throughput installed:

Wireshark or other network analysis tools

Remote access tools

Check if the TCP stack has been changed from the original code or configuration:

Old DLLs may influence OS behavior

Other NICs with full TCP offload support may have changed the default TCP stack behavior

Firewall and antivirus interference:

Firewalls and antivirus software check different layers of traffic in real time, so it is possible that they

may degrade performance.

Please consult your firewall/antivirus provider for the best throughput configuration.

OS Optimization

Windows OS

Make sure the latest updates for Windows are installed. Microsoft provides Performance Tuning Guidelines

for Windows Server clients:

http://msdn.microsoft.com/en-us/windows/hardware/gg463392.aspx

TCP/IP Tuning

Default TCP/IP optimization for Windows allows 10GbE wire speed network performance for limited time

periods. Usually, TCP connections are limited by timespan and do not stay live for more than a few hours.

The default Windows TCP/IP stack is optimized for WAN and long distance media connections.

For a long-lasting LAN TCP/IP connection, please refer to the Benchmark Performance Tuning section of

this document for proper OS configuration.

Receive Side Scaling (RSS)

RSS is a mechanism for distributing received traffic across available processors or cores by assigning hash

values to an indirection table. At least 4 cores must be allocated in order to achieve maximum throughput for

bidirectional 10GbE traffic.

Linux OS

The default Linux OS optimizes IPv4 traffic for the best user experience. Usually, TCP/IP traffic will remain

stable for long periods of time with no further optimization. However, some Linux distributions may have

enabled different IRQ SMP affinity methods by default. See IRQ SMP affinity in the Benchmark Performance

Tuning section for more details.
