Product ID: ST4000PEXPSE
The ST4000PEXPSE 4-Port PoE 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 PoE devices.
The PCI express PoE 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 PoE devices such as IP cameras, IP phones or wireless access points.
Suitable for any standard profile PCIe-enabled client, server or workstation, the PoE network card supports features such as Jumbo Frames (up to 9KB), VLAN tagging and Wake on LAN (WoL).
Backed by a StarTech.com 2-year warranty and free lifetime technical support.

Sometimes an on-board network interface card (NIC) conflicts with a new NIC. In these cases it is best to disable the on-board NIC.
The best way to disable your on-board NIC is to go into your BIOS and disable it there if possible. To do this, consult your motherboard manual.
You can also disable any NIC in Windows. Here is how you do this:
First click Start, or, in Windows 10 and 8, hold down the Windows key and press X. Then click Control Panel.
If you are experiencing speed or connectivity issues, it is best to set a specific speed at half or full duplex in your settings. You can set your network adapter to perform at a certain speed, but the device that the adapter is connected to (whether it is a router, switch, or computer) must also be able to perform at the same speed.
Note: You must log in as the local administrator before you continue.
