2.5G Multi-Gigabit PCIe Network Card

This PCI Express network adapter adds a single RJ45 port supporting 2.5G, 1G, 100M and 10M speeds to a desktop or server. It targets administrators and enthusiasts who need faster wired throughput than standard gigabit without moving to 10G infrastructure. The card installs in an open x1 slot and works with existing Cat5e or better cabling.

PCIe 2.1 x1 Interface with Low-Profile Bracket

The card complies with the PCI Express 2.1 specification and fits both standard and low-profile chassis using the included spare bracket. Its single RJ45 connector carries all four negotiated speeds and supports IEEE 802.3az Energy Efficient Ethernet, 802.3x flow control and 802.1Q VLAN tagging for managed networks. Wake-on-LAN and RealWoW remote wake-up are also supported.

Upgrade from Standard Gigabit NICs

Replaces a 1G onboard or add-in adapter when 2.5G switches or routers are present and cabling is already Cat5e or Cat6. The jump is worth it for large file transfers, backup targets or virtualisation hosts that saturate gigabit but do not justify 10G hardware. Jumbo frames up to 16K bytes further improve throughput in compatible environments.
