Introduction
The ST2000SPEXI PCI Express Dual Port Gigabit Network Card lets you add two
gigabit Ethernet ports to a desktop computer through a single, four-lane (x4 or higher)
PCI Express slot.Each port is fully compatible with IEEE 802.3/u/ab standards, for
10/100/1000 Mbps auto-negotiation.
This 2-port GbE network card is based on the high-performance Intel® I350
chipset, which oers several advanced driver options including IEEE 802.3ad link
aggregation / teaming support, enabling you to add additional bandwidth to your
system. Support for Jumbo Frames, full-duplex operation and 802.1q VLAN tagging
also aid in creating an ecient network conguration.
Also useful for virtualization applications or setting up a dual-homed host
conguration, this dual-port network card lets you accommodate several complex
network scenarios, to meet your business needs. For added versatility, the controller
card is equipped with a standard prole bracket and includes a low-prole/half-height
bracket for installation in small form-factor computers.

Installation
Hardware Installation
WARNING! PCI Express cards, like all computer equipment, can be severely damaged
by static electricity. Be sure that you are properly grounded before opening your
computer case or touching your PCI Express card. StarTech.com recommends that you
wear an anti-static strap when installing any computer component. If an anti-static
strap is unavailable, discharge yourself of any static electricity build-up by touching a
large grounded metal surface (such as the computer case) for several seconds. Also be
careful to handle the card by its edges and not the gold connectors.
1. Turn your computer o and any peripherals connected to the computer (i.e. Printers,
external hard drives, etc.). Unplug the power cable from the rear of the power
supply on the back of the computer and disconnect all peripheral devices.
2. Remove the cover from the computer case. See documentation for your computer
system for details.
3. Locate an open PCI Express slot and remove the metal cover plate on the rear of the
computer case (Refer to documentation for your computer system for details.). Note
that this card will work in PCI Express slots of additional lanes (i.e. x8 or x16 slots).
4. Insert the card into the open PCI Express slot and fasten the bracket to the rear of
the case.
Note: If installing the card into a low prole desktop system, replacing the
preinstalled standard prole bracket with the included low prole (half height)
installation bracket may be necessary.

Advanced Features (Windows)
Link Speed & Duplex
In the default mode, the adapter will attempt to auto-negotiate with its link partner
to determine the best setting. If the adapter cannot establish link with the link partner
using auto-negotiation, you may need to manually congure the adapter and link
partner to identical settings to establish link and pass packets. This should only be
needed when attempting to link with an older switch that does not support auto-
negotiation or one that has been forced to a specic speed or duplex mode. Your link
partner must match the setting you choose.
CAUTION: Only experienced network administrators should force speed and duplex
manually. The settings at the switch must always match the adapter settings. Adapter
performance may suer or your adapter may not operate if you congure the adapter
dierently from your switch.
Manually setting Speed &Duplex
By default, auto-negotiation is enabled. Change this setting only to match your
link partner.
1. Open the Device Manager and expand the Network Adapters section.
2. Right-click the Intel i350 Gigabit Network Connection you wish to congure and
select Properties.
3. Click the Link Speed tab.
4. Select the appropriate speed and duplex from the Speed and Duplex pull
down menu.
5. Click OK.
Gigabit Network Device Considerations
Per the IEEE specication, gigabit speed is available only in full duplex.
The settings available when auto-negotiation is disabled are:
• 10 Mbps or 100 Mbps Full duplex (requires a full duplex capable link partner set to
full duplex). The adapter can send and receive packets at the same time. You must
set this mode manually.
• 10 Mbps or 100 Mbps Half duplex (requires a link partner set to half duplex). The
adapter performs one operation at a time; it either sends or receives. You must set
this mode manually.

Instruction Manual
7
• Auto-Negotiation 1000 Mbps. The adapter only advertises gigabit speed at
full duplex.
Advanced Tab
All of the settings explained in the following sections can be accessed / modied from
the Advanced tab in the device properties:
1. Open the Device Manager and expand the Network Adapters section.
2. Right-click the Intel i350 Gigabit Network Connection you wish to congure
and select Properties.
3. Click the Advanced tab.
4. Make your desired modications.
5. Click OK to apply the changes.
Gigabit Master Slave Mode
Decides whether the adapter or link partner, is designated as the master. The other
device is designated as the slave. Changing the setting can improve link quality with
certain link partners.
NOTE: Some multi-port devices can be forced to master mode. If forced to master
mode, the device can either disconnect or downshift to a 100-Mbps link. This issue can
also occur in a Forced Slave to Forced Slave mode. Changing this setting can cause a
momentary loss of connectivity.

Instruction Manual
8
Interrupt Moderation
Sets the Interrupt Throttle Rate (ITR), the rate at which the controller moderates
interrupts.
The default setting is optimized for common congurations. Changing this setting can
improve network performance on certain network and system congurations.
Options:
Adaptive (ITR = -1, no interrupts/sec, it is dynamically changed by the driver)
O (ITR = 0, no limit)
Minimal (ITR = 200)
Low (ITR = 400)
Medium (ITR = 950)
High (ITR = 2000)
Extreme (ITR = 3600)
When an event occurs, the adapter generates an interrupt, which allows the driver to
handle the packet. At greater link speeds, more interrupts are created, and CPU rates
also increase. This results in poor system performance. When you use a higher ITR
setting, the interrupt rate is lower, and the result is better system performance.
NOTE: A higher ITR rate also means the driver has more latency in handling packets.
If the adapter is handling many small packets, lower the ITR so the driver is more
responsive to incoming and outgoing packets.
Jumbo Packet
Jumbo frames are Ethernet frames that are larger than 1518 bytes. You can use Jumbo
Frames to reduce server CPU utilization and increase throughput. However, additional
latency may be introduced.
NOTES:
• All equipment on the network must also support the larger frame size. When
setting up Jumbo Frames on other network devices, be aware that dierent network
devices calculate Jumbo Frame size dierently. Some devices include the header
information in the frame size while others do not. Intel adapters do not include
header information in the frame size. When conguring Jumbo Frames on a switch,
set the frame size four bytes higher for CRC, plus four bytes if you are using VLANs or
QoS packet tagging.
• Jumbo Frames are supported at 1000 Mbps only. Using Jumbo Frames at 10 or 100
Mbps is not supported and may result in poor performance or loss of link.

Instruction Manual
9
Restrictions:
• Jumbo Frames can be implemented simultaneously with VLANs and teaming,
however Jumbo frames are not supported in multi-vendor team congurations.
• Supported protocols are limited to IP (TCP, UDP).
• Jumbo frames require compatible switch connections that forward Jumbo Frames.
To congure Jumbo Frames at the switch, consult your network administrator or
switch user's guide.
• When standard sized Ethernet frames (64 to 1518 bytes) are used, there is no benet
to conguring Jumbo Frames.
• The Jumbo Frames setting on the switch must be set to at least 8 bytes larger than
the adapter setting for Microsoft Windows operating systems, and at least 22 bytes
larger for all other operating systems.
Large Send Ooad
Enables the adapter to ooad the task of segmenting TCP messages into valid
Ethernet frames.
Because the adapter hardware can complete data segmentation much faster than
operating system software, this feature can improve transmission performance. The
adapter also uses fewer CPU resources.
Large Send Ooad can be congured separately for IPv4 and IPv6.
Locally Administered Address
The Locally Administered Address feature allows you to override a device’s MAC
Address and assign an address of your choice. The address is a 12-digit hexadecimal
number in the range: 0000 0000 0001 – FEFF FFFF FFFF.
CAUTION: Make sure no other systems on the network use this address.
NOTES:
• Do not use a multicast address (least signicant bit of the high byte = 1).
For example, in the address 0y123456789A, "y" cannot be an odd number. (y must
be 0, 2, 4, 6, 8, A, C, or E.)
• To restore the default MAC address, click Use Default.
• You cannot change the address if the adapter is part of a team.
• Changing this setting may cause a momentary loss of connectivity.

Instruction Manual
10
The LAA setting is disabled and cannot be changed if one or more of the following
is true:
• The device is congured to iSCSI boot primary or secondary.
• The device or team is bound to the Microsoft Virtual Switch Protocol.
Log Link State Event
Enables the logging of the following link state changes to the system event log:
LINK_UP_CHANGE - When this message is displayed, the link is up.
LINK_DOWN_CHANGE - When this message is displayed, the link is down. To
investigate this issue, click the Link Speed tab and run diagnostics.
LINK_DUPLEX_MISMATCH - When this message is displayed, there is a mismatch in
duplex between the adapter and the link partner. To investigate this issue, click the
Link Speed tab and change the speed and duplex settings appropriately.
Maximum Number of RSS Queues
Congures the number of Receive Side Scaling (RSS) queues:
• One queue is used when low CPU utilization is required.
• Two queues are used when good throughput and low CPU utilization are required.
• Four or more queues are used for applications that demand high transaction rates
such as web server based applications. With this setting, the CPU utilization may
be higher.
NOTES:
• RSS is not supported on some adapters congured to use Virtual Machine Queues
(VMQ). For these adapters VMQ takes precedence over RSS. RSS is disabled.
• Using eight or more queues on Microsoft Windows Server 2008 requires the system
to reboot.
• Changing this setting may cause a momentary loss of connectivity.

Instruction Manual
11
Packet Priority & VLAN
Enables sending and receiving of IEEE 802.3ac tagged frames, which include:
802.1p QoS (Quality of Service) tags for priority-tagged packets
802.1Q tags for VLANs
Intel® PROSet automatically enables 802.1p tagging when you set up a VLAN. You
cannot disable QoS Packet Tagging on a VLAN because tagging is required for VLANs.
When this feature is enabled, tagged packets use the queue settings dened by the
operating system Priority Level Denition.
When this setting is disabled, the adapter cannot tag outgoing packets with
802.1p/802.1Q tags.
Performance Options
Receive Descriptors or Receive Buers
Sets the number of buers used by the driver when copying data to the protocol
memory. Increasing this value can enhance the receive performance, but also
consumes system memory.
Receive Descriptors are data segments that enable the adapter to allocate received
packets to memory. Each received packet requires one Receive Descriptor, and each
descriptor uses 2 KB of memory.
Transmit Descriptors or Transmit Buers
Denes the number of Transmit Descriptors, which are data segments that enable the
adapter to track transmit packets in the system memory. Depending on the size of the
packet, each transmit packet requires one or more Transmit Descriptors.
You might choose to increase the number of Transmit Descriptors if you notice a
problem with transmit performance. Increasing the number of Transmit Descriptors
can enhance transmit performance. But, Transmit Descriptors consume system
memory. If transmit performance is not an issue, use the default setting.

Instruction Manual
12
Receive Side Scaling
Enables Receive Side Scaling (RSS). RSS balances receive trac across multiple CPUs or
CPU cores. This setting has no eect if your system has only one processing unit.
NOTES:
• RSS must be enabled for Intel® I/O Acceleration Technology to function under
Microsoft Windows Server 2003.
• RSS is not supported on some adapters congured to use Virtual Machine Queues
(VMQ). For these adapters VMQ takes precedence over RSS. RSS is disabled.
• Changing this setting can cause a momentary loss of connectivity.
Teaming Notes:
• If RSS is not enabled for all adapters in a team, RSS is disabled for the team.
• If an adapter that does not support RSS is added to a team, RSS is disabled for
the team.
• If a non-Intel adapter is added to a team, its RSS settings must match the Intel
adapters in the team.
• Not all adapters support all RSS queue settings
TCP/IP Ooading Options
IPv4 Checksum Ooad
Enables the adapter to verify the IP checksum on received packets and compute
checksum on transmitted packets. Enabling this feature can improve IP performance
and reduce CPU utilization.
NOTE: Changing this setting may cause a momentary loss of connectivity.
TCP Checksum Ooad
Enables the adapter to verify the TCP checksum on received packets and compute
checksum on transmitted packets. Enabling this feature can improve TCP performance
and reduce CPU utilization.
This setting can be congured separately for IPv4 and IPv6.
NOTE: Changing this setting may cause a momentary loss of connectivity.

Instruction Manual
13
Transmit IP Checksum
Allows the adapter to compute the IP checksum of transmitted packets. This feature
can improve IP transmit performance and reduce CPU utilization. With Ooading
disabled, the operating system veries the IP checksum.
UDP Checksum Ooad
Enables the adapter to verify the UDP checksum on received packets and compute
checksum on transmitted packets. Enabling this feature can improve UDP performance
and reduce CPU utilization.
This setting can be congured separately for IPv4 and IPv6.
Wait for Link
Decides if the driver waits for Auto Negotiation to be successful before reporting the
link state.
Options
O: Driver does not wait for Auto Negotiation
On: Driver does wait for Auto Negotiation. If the speed is not set to Auto
Negotiation, the driver waits for a short time for link to complete and then
reports the link state.
Auto Detect: Automatically set to On or O depending on speed and adapter
type when the driver is installed.
• O for copper Intel PRO/1000 adapters with a speed of Auto
• On for copper Intel PRO/1000 adapters with a forced speed and duplex
• On for ber Intel PRO/1000 adapters with a speed of Auto
Power Management
The Intel® PROSet Power Management tab replaces the standard Microsoft Windows
Power Management tab in Device Manager. It includes the Power Saver and Wake on
LAN (WoL) options that were previously included on the Advanced tab. The standard
Windows power management functionality is incorporated on the Intel PROSet tab.
The Intel PROSet Power Management tab includes several settings that control the
adapter's power consumption.

Instruction Manual
14
Energy Ecient Ethernet
The Energy Ecient Ethernet (EEE) feature allows a capable device to enter Low Power
Idle between bursts of network trac. Both ends of a link must have EEE enabled for
any power to be saved. Both ends of the link will resume full power when data needs
to be transmitted. This transition may introduce a small amount of network latency.
NOTES:
• Both ends of the EEE link must automatically negotiate link speed.
• EEE is not supported at 10Mbps.
Remote Wake-Up and Wake on LAN
Microsoft Windows and Windows Server do not support wake from a power-o (S5)
state, only from standby (S3) or hibernate (S4). When shutting down the system, they
shutdown ACPI devices, including Intel adapters. This disarms the adapter’s remote
wake up capability. However, in some ACPI-capable computers, the BIOS may have a
setting that allows you to override the operating system and wake from an S5 state
anyway. If there is no support for wake from S5 state in your BIOS settings, you are
limited to Wake From Standby when using these operating systems.
NOTE:
• In some scenarios, the “Wait for Link” option (located on the Advanced Tab) needs
to be set to On for Wake on LAN to function properly. If you are experiencing any
diculty getting WoL to work, please adjust this setting and try again.
Conguring Power Management Settings
1. Open the Device Manager and expand the Network Adapters section.
2. Right-click the Intel i350 Gigabit Network Connection you wish to congure
and select Properties.
3. Click the Power Management tab.
4. Set your desired power management options.
5. Click OK to apply the changes.

Instruction Manual
15
Teaming
Advanced Network Services (ANS) Teaming, a feature of the Advanced Network
Services component, lets you take advantage of multiple network ports / adapters in a
system by grouping them together. ANS teaming can use features like fault tolerance
and load balancing to increase throughput and reliability. Before you can set up ANS
teaming in Windows, you must install Intel® PROSet software.
IMPORTANT:
• Before creating a team, adding or removing team members, or changing advanced
settings of a team member, make sure each team member has been congured
similarly. Settings to check include VLANs and QoS Packet Tagging, Jumbo Frames,
and the various ooads. These settings are available in Intel PROSet's Advanced
tab. Pay particular attention when using dierent adapter models or adapter
versions, as adapter capabilities vary.
• If team members implement advanced features dierently, failover and team
functionality will be aected. To avoid team implementation issues, create teams
that use similar adapter types and models.
• Reload the team after adding an adapter or changing any advanced features. One
way to reload the team is to select a new preferred primary adapter. Although there
will be a temporary loss of network connectivity as the team recongures, the team
will maintain its network addressing schema.

Instruction Manual
16
NOTES:
• Be sure to use the latest available drivers.
• Hot Plug operations for an adapter that is part of a team are only available in
Windows Server.
• For SLA teams, all team members must be connected to the same switch. For
AFT, ALB, and RLB teams, all team members must belong to the same subnet. The
members of an SFT team must be connected to a dierent switch.
• Teaming only one adapter port is possible, but provides no benet.
• NDIS 6.2 introduced new RSS data structures and interfaces. Because of this, you
cannot enable RSS on teams that contain a mix of adapters that support NDIS 6.2
RSS and adapters that do not.
• If a team is bound to a Hyper-V virtual NIC, you cannot change the Primary or
Secondary adapter.
• Intel adapters that do not support Intel PROSet may still be included in a team.
However, they are restricted in the same way non-Intel adapters are. See Multi-
Vendor Teaming below for more information.
• To assure a common feature set, some advanced features, including hardware
ooading, are automatically disabled when an adapter that does not support Intel
PROSet is added to a team.
• Hot Plug operations in a Multi-Vendor Team may cause system instability. We
recommended that you restart the system or reload the team after performing Hot
Plug operations with a Multi-Vendor Team.
• Spanning tree protocol (STP) should be disabled on switch ports connected to
teamed adapters in order to prevent data loss when the primary adapter is returned
to service (failback). Alternatively, an activation delay may be congured on the
adapters to prevent data loss when spanning tree is used. Set the Activation Delay
on the advanced tab of team properties.
• ANS teaming of Virtual Function devices inside a Windows 2008 R2 guest running
on an open source hypervisor is supported.
• Fiber Channel over Ethernet/Data Center Bridging will be automatically disabled
when an adapter is added to a team with non-FCoE/DCB capable adapters.

Instruction Manual
17
Conditions that may prevent you from teaming a device
During team creation or modication, the list of available team types or list of available
devices may not include all team types or devices. This may be caused by any of several
conditions, including:
• The operating system does not support the desired team type.
• The device does not support the desired team type or does not support
teaming at all.
• The devices you want to team together use dierent driver versions.
• TOE (TCP Ooad Engine) enabled devices cannot be added to an ANS team and will
not appear in the list of available adapters.
• You can add Intel® Active Management Technology (Intel® AMT) enabled devices
to Adapter Fault Tolerance (AFT), Switch Fault Tolerance (SFT), and Adaptive Load
Balancing (ALB) teams. All other team types are not supported. The Intel AMT
enabled device must be designated as the primary adapter for the team.
• The device's MAC address is overridden by the Locally Administered Address
advanced setting.
• The device has a virtual NIC bound to it.
• The device is part of a Microsoft Load Balancing and Failover (LBFO) team.
Microsoft Load Balancing and Failover (LBFO) teams
Intel ANS teaming and VLANs are not compatible with Microsoft's LBFO teams. Intel®
PROSet will block a member of an LBFO team from being added to an Intel ANS team
or VLAN. You should not add a port that is already part of an Intel ANS team or VLAN to
an LBFO team, as this may cause system instability. If you use an ANS team member or
VLAN in an LBFO team, perform the following procedure to restore your conguration:
1. Reboot the machine
2. Remove LBFO team. Even though LBFO team creation failed, after a reboot Server
Manager will report that LBFO is Enabled, and the LBFO interface is present in the
‘NIC Teaming’ GUI.
3. Remove the ANS teams and VLANS involved in the LBFO team and recreate them.
This is an optional (all bindings are restored when the LBFO team is removed ), but
strongly recommended step
NOTE: If you add an Intel AMT enabled port to an LBFO team, do not set the port
to Standby in the LBFO team. If you set the port to Standby you may lose AMT
functionality.

ANS Teaming Types
Adapter Fault Tolerance (AFT) - provides automatic redundancy for a server's
network connection. If the primary adapter fails, the secondary adapter takes over.
During normal operation, the backup adapters are in standby. Adapter Fault Tolerance
supports two to eight adapters per team. This teaming type works with any hub
or switch. During normal operation, the backup adapters are in standby. All team
members must be connected to the same subnet.
Switch Fault Tolerance (SFT) - provides failover between two adapters connected to
separate switches. Switch Fault Tolerance supports two adapters per team. Spanning
Tree Protocol (STP) must be enabled on the switch when you create a SFT team.
During normal operation, the secondary adapter is in standby. When SFT teams are
created, the Activation Delay is automatically set to 60 seconds. This teaming type
works with any switch or hub. All team members must be connected to the same
subnet. In SFT teams, each adapter in the team can operate at a dierent speed than
the other.
• You can set up monitoring between an SFT team and up to ve IP addresses. This
allows you to detect link failure beyond the switch. You can ensure connection
availability for several clients that you consider critical. If the connection between
the primary adapter and all of the monitored IP addresses is lost, the team will
failover to the secondary adapter.
• Switch Fault Tolerance can detect failures when they occur on either teamed
adapter, on either cable connecting the teamed adapter to its switch, or on switch
ports connected to the adapters, if link is lost
Adaptive Load Balancing (ALB) - uses software to balance routable trac among
a team of two to eight adapters or LOMs (the team must include at least one server
adapter) connected to the same subnet. The software analyzes the send and transmit
loading on each adapter and balances the rate across the adapters based on
destination address. Adapter teams congured for ALB also provide the benets of
fault tolerance.
NOTES:
• ALB does not load balance non-routed protocols such as NetBEUI and some IPX*
trac.
• You can create an ALB team with mixed speed adapters. The load is balanced
according to the lowest common denominator of adapter capabilities and the
bandwidth of the channel.
