Technical Overview

This network card is built around the Realtek RTL8125B chipset, which enables reliable 2.5Gbps performance with 802.3at PoE support. The card delivers up to 30W of power over the Ethernet connection, allowing it to power compatible devices such as IP cameras, wireless access points, or VoIP phones directly from the host system.

The adapter maintains backward compatibility with existing 1000BASE-T and 100BASE-TX networks while offering significantly higher throughput for bandwidth-intensive applications. Its single RJ-45 port supports data transfer rates up to 2.44 Gbit/s, effectively doubling the bandwidth available from standard Gigabit connections.

Key Product Advantages

This network card combines high-speed connectivity with PoE functionality in a single expansion card, eliminating the need for separate power injectors or adapters. The 2.5Gbps capability provides a substantial performance boost over standard Gigabit Ethernet while remaining compatible with existing network infrastructure.

Simplified Power Delivery

The integrated 802.3at PoE support delivers up to 30W of power through the Ethernet cable, reducing cable clutter and simplifying installation of powered devices.

  • Eliminates need for separate power injectors
  • Supports PoE+ compatible devices
  • Centralized power management

Performance Upgrade Path

2.5GBase-T technology provides a cost-effective intermediate step between Gigabit and 10 Gigabit networking, offering significantly improved throughput without requiring complete infrastructure overhaul.

  • Backward compatible with Gigabit networks
  • Uses existing twisted pair cabling
  • Doubles bandwidth of standard Gigabit

Deployment / Use Cases

This PoE network card is ideal for workstations or servers that need to connect to both high-speed networks and PoE-powered devices. It's particularly useful in environments where network bandwidth requirements have outgrown traditional Gigabit capabilities but don't yet justify the expense of 10 Gigabit infrastructure.

Common deployment scenarios include video editing workstations requiring fast network storage access, surveillance system servers connecting to multiple IP cameras, small business servers supporting VoIP systems, or development systems transferring large files between workstations and servers.

Surveillance & Security Systems

Power and connect multiple IP cameras directly from a surveillance server, reducing cable complexity while maintaining high-bandwidth video streaming capabilities.

Small Business Infrastructure

Upgrade existing servers to support faster file transfers and VoIP systems simultaneously, improving both data throughput and communication reliability.

Physical Profile

The card features a low-profile form factor with dimensions of 2.50" (63.50 mm) wide and 0.60" (15.24 mm) high, making it compatible with both standard and small form factor systems. The included low-profile bracket allows installation in space-constrained chassis, while the card's lightweight design at approximately 7.80 oz (221.13 g) ensures minimal impact on system stability.

The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: Low Profile, 2.50" (63.50 mm), 7.80 oz (221.13 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ

What systems is this network card compatible with?

The ST1000PEXPSE is compatible with desktop computers and servers that have an available PCI Express 2.1 x1 slot or larger. It supports both Windows and Linux operating systems, though specific driver availability should be verified for your distribution. The low-profile bracket makes it suitable for standard and small form factor cases.

What Power over Ethernet standard does this card support?

This network card supports the IEEE 802.3at PoE+ standard, which delivers up to 30W of power over the Ethernet connection. This is sufficient to power most PoE+ compatible devices such as IP cameras, wireless access points, VoIP phones, and other network equipment that requires both data and power through a single cable.

What is the maximum data transfer rate of this adapter?

The card supports a maximum data transfer rate of 2.44 Gbit/s using 2.5GBase-T network technology. This provides approximately 2.5 times the throughput of standard Gigabit Ethernet (1 Gbit/s) while maintaining compatibility with existing Category 5e or better twisted pair cabling up to 100 meters in length.

Does this card require special drivers or software?

The card uses the Realtek RTL8125B chipset, which is supported by drivers included in most modern operating systems. However, for optimal performance and feature support, it's recommended to download the latest drivers from the StarTech.com website. The manufacturer provides comprehensive documentation and driver updates for both Windows and Linux environments.

What is included in the package with this network card?

The package includes the 2.5Gigabit Ethernet adapter card itself, one low-profile bracket for installation in small form factor cases, and a quick-start guide. The bracket can be swapped with the existing bracket if needed for different case configurations. No additional cables or power adapters are required for basic operation.

What warranty coverage does StarTech.com provide for this product?

StarTech.com provides a 2-year limited warranty for the ST1000PEXPSE network card. This warranty covers defects in materials and workmanship under normal use. The product is also RoHS and WEEE compliant, meeting environmental standards for hazardous substance restriction and electronic waste management.
