Deployment / Use Cases
The ST4000PEXPSE is ideal for expanding network connectivity while adding PoE capabilities to systems that lack built-in PoE support. It's particularly valuable in surveillance installations where multiple IP cameras need both data and power, or in office environments deploying VoIP phone systems and wireless access points.
Small business servers can benefit from the additional network ports for segmentation or link aggregation, while the PoE functionality supports connected devices without requiring separate electrical outlets at each endpoint. The card's compact form factor and standard bracket design ensure compatibility with most desktop and tower chassis.
Surveillance Systems
Power and connect multiple IP cameras from a central server or workstation, simplifying installation and reducing power cable runs throughout the facility.
Office Network Expansion
Add PoE ports to support VoIP phones, wireless access points, and other networked devices while maintaining Gigabit data throughput for all connected equipment.
Physical Profile

FAQ
What devices can this PoE network card power?
The ST4000PEXPSE can power any IEEE 802.3at compliant PoE device, including IP cameras, VoIP phones, wireless access points, and other network equipment that requires up to 25.5 watts per port. It supports both Type 1 and Type 2 PoE standards, making it compatible with a wide range of business and surveillance equipment.
What type of PCI Express slot does this card require?
This network card requires a PCI Express x4 slot or larger (x8, x16) for installation. It uses a PCIe x4 host interface to provide sufficient bandwidth for all four Gigabit ports operating simultaneously at full speed. The card will physically fit in any standard PCIe slot while utilizing the electrical connections of an x4 interface.
Does this card need external power connections?
Yes, the card requires external power to deliver PoE to connected devices. It includes both SATA and LP4 Molex power connectors, allowing you to choose the most convenient power source from your system's available connections. The external power input supplies the necessary current for PoE delivery while the PCIe slot provides data connectivity and minimal card power.
