- Delivers data and up to 25.5W per port
- Consolidates power and data cabling
Enhanced System Protection
The unique surge protection design helps prevent electrical damage to the host system, a critical consideration for deployments in environments prone to power fluctuations.
- Mitigates surge damage risk
- Protects host PC investment
Universal Bracket Compatibility
Included full-height and low-profile brackets allow installation in virtually any desktop or server chassis, providing deployment flexibility without requiring additional parts.
- Fits standard and small form factors
- No extra purchase needed for low-profile cases
Deployment / Use Cases
This adapter is ideal for expanding network connectivity in workstations or servers that need to support multiple Power over Ethernet devices. It is commonly deployed in small office environments, retail POS systems, or digital signage setups where adding separate PoE switches is impractical or cost-prohibitive.
IT administrators can use it to add dedicated network segments for VoIP telephony, connecting IP phones directly to a server for call management. It also serves well in security and surveillance deployments, powering IP cameras while providing a high-bandwidth feed back to a recording server, or in retail environments to power wireless access points while maintaining a wired backbone connection.
VoIP Telephony Setup
Connect multiple IP phones directly to a server running PBX software, providing both power and data from a single card to streamline office communication systems.
Surveillance & Security
Power IP cameras and receive high-definition video streams over a single cable, simplifying installation for CCTV or monitoring systems in small to medium businesses.
Physical Profile
The card features a compact plug-in card form factor measuring 2.70 inches in height, 0.70 inches in width, and 0.70 inches in thickness, with a light weight of approximately 3.70 ounces. Its slim profile ensures it fits comfortably in most PCI Express slots without obstructing adjacent components. The design includes appropriate clearance for the built-in SATA and LP4 Molex power connectors, which are necessary for delivering the full PoE power budget to connected devices.
