Four-port PoE+ network card

The SIIG LB-GE0811-S1 adds four independent Gigabit Ethernet ports with Power over Ethernet capability through a PCI Express 2.1 slot. Each port delivers up to 30 W of power under the IEEE 802.3at PoE+ standard. The Intel I350-T4 chipset provides reliable connectivity for servers and desktop systems.

Built for PoE deployments, not high-speed uplinks

This card suits installers who need to power IP cameras, wireless access points or VoIP phones directly from the network port without separate injectors. Builders who require more than four ports or link speeds above 1 Gbps should consider other solutions.

PCI Express 2.1 interface at 5.0 GT/s

The card requires an available PCI Express slot compatible with the 2.1 specification operating at 5.0 GT/s. Verify that your motherboard or riser supports this interface before purchase.

Questions about this item

Will this PCI Express 2.1 card work in my older motherboard that only has PCI Express 2.0 slots?

Yes, the card uses a PCI Express 2.1 interface at 5.0 GT/s and is backward compatible with PCI Express 2.0 and 1.0 slots, though it will operate at the lower slot speed.

How can I verify the Intel I350-T4 chipset is delivering 1 Gbps on all four RJ45 ports after installation?

Check the link speed in your operating system network settings or switch management interface; each port should negotiate 1 Gbps full duplex and show active PoE+ power delivery up to 30W per port when devices are connected.

Does the box include the low-profile bracket for slim cases or do I need to buy it separately?

The standard package includes the full-height bracket only; a low-profile bracket for slim or 1U chassis is not included and must be purchased separately if required.
