The ST4000PEXPSE 4-Port Po E NIC lets you add four Gigabit Power over Ethernet ports through a single PCI Express slot. Each port can provide up to 25. 5W of power, combining network data and power over a single Ethernet cable for reduced cable clutter and added convenience for remote Po E devices. The PCI express Po E card supports the IEEE 802. 3at (Type 1 and 2) standard for Power Sourcing Equipment (PSE), and can deliver up to 48V DC power to compliant Powered Devices (PD). This eliminates the need for a separate power source and data connection for Po E devices such as IP cameras, IP phones or wireless access points. Suitable for any standard profile PCIe-enabled client, server or workstation, the Po E network card supports features such as Jumbo Frames (up to 9KB), VLAN tagging and Wake on LAN (Wo L). Backed by a Star Tech. com 2-year warranty and free lifetime technical support.
