Four RJ45 Gigabit LAN Ports

A major feature of the W224-ST708 PCI-E Expansion Card is its four RJ45 Gigabit Ethernet ports.

This multi-port configuration allows a compatible computer system to add multiple wired Ethernet connections through one PCI Express expansion card. It can be useful for systems that need several network interfaces for different devices, network segments, or communication tasks.

Compared with a single-port network card, the four-port design provides more connection capacity while reducing the need to install multiple individual Ethernet cards.

The W224-ST708 can therefore be considered for applications such as industrial computers, workstations, system integration projects, network appliances, and multi-network desktop environments.

10/100/1000 Mbps Auto-Negotiation

The W224-ST708 supports 10 Mbps, 100 Mbps, and 1000 Mbps Ethernet speeds with auto-negotiation.

Network Type	Supported Speed
Ethernet	10 Mbps
Fast Ethernet	100 Mbps
Gigabit Ethernet	1000 Mbps

Its 1000BASE-T capability provides Gigabit Ethernet connectivity, while backward compatibility with 10/100BASE-T networks allows the card to operate in existing network environments.

This flexibility is valuable for B2B customers managing mixed network infrastructures where different connected devices may operate at different speeds.

RTL8111F Gigabit Ethernet Chipset

The W224-ST708 uses the RTL8111F chipset as the core of its Gigabit Ethernet architecture.

For system builders and technical buyers, chipset information is an important purchasing factor because it helps identify the network controller platform and evaluate compatibility with the intended system.

Combined with four RJ45 interfaces, the RTL8111F-based configuration supports reliable multi-port network expansion through the PCI Express bus.

PCI Express x1 Interface

The card uses a PCI Express 1-Lane x1 interface and complies with PCI-Express Revision 1.1.

A compatible PCI Express expansion slot is required for installation. Before ordering, buyers should confirm the motherboard slot configuration and available chassis space.

The W224-ST708 also supports both standard and low-profile chassis configurations, providing additional flexibility for different computer enclosure designs.

This makes the card suitable for both conventional desktop systems and more compact installations where low-profile expansion hardware may be required.

Jumbo Frame Support up to 9K

The W224-ST708 supports Jumbo Frames up to 9K bytes.

Jumbo Frame capability can be useful in compatible Gigabit Ethernet environments where larger Ethernet frames are used to reduce protocol overhead during large-volume data transmission.

Actual performance depends on the complete network environment, including switches, connected devices, cabling, operating system settings, and driver configuration.

For customers planning to use Jumbo Frames, all relevant network components should support the required frame size.

VLAN and Network Traffic Management

The W224-ST708 supports IEEE 802.1Q VLAN tagging, allowing compatible network environments to use Virtual LAN functionality.

It also supports IEEE 802.1P Layer 2 Priority Encoding, which can be used for traffic prioritization in supported network configurations.

These features can be useful for system integrators designing networks that require logical segmentation or different traffic priority levels.

Additional network features include:

• IEEE 802.3x Flow Control

• Half duplex operation

• Full duplex operation

• 10/100/1000 Mbps auto-negotiation

IEEE Ethernet Standards

The W224-ST708 PCI-E network card complies with several common Ethernet standards.

• IEEE 802.3

• IEEE 802.3u

• IEEE 802.3ab

• IEEE 802.3x

• IEEE 802.1P

• IEEE 802.1Q

These standards cover Ethernet communication, Fast Ethernet, Gigabit Ethernet, flow control, priority encoding, and VLAN tagging.

The card is also compatible with existing CAT-5 UTP cabling, helping simplify integration into supported wired network infrastructures.

Power Saving and Wake-on-LAN Functions

The W224-ST708 includes power-management features designed for compatible computer systems.

It supports power-down and link-down power saving, helping reduce network controller power consumption when appropriate.

The card also supports Wake-on-LAN and remote wake-up functionality. In supported systems, these functions can allow a computer to be remotely awakened through a network connection.

Actual Wake-on-LAN functionality depends on motherboard support, BIOS settings, operating system configuration, drivers, and network environment.

Windows Operating System Support

The W224-ST708 supports a broad range of Windows operating systems, including:

• Windows 98SE

• Windows ME

• Windows 2000

• Windows XP

• Windows Server 2003

• Windows Vista

• Windows 7

• Windows Server 2008

• Windows 8

• Windows 8.1

• Windows 10

• 32-bit and 64-bit environments where specified

For B2B projects, customers should confirm the exact operating system version and driver requirements before large-volume deployment.
