The FE-551 is the most popular and reliable Fast Ethernet PCI card for Mac. Designed for any Macs with a PCI slot, FE-551 adds a Fast Ethernet port to your Mac so you can connect to any standard Ethernet network running at 10Mbps or 100Mbps. Whether you are upgrading your older Mac to Ethernet or replacing your worn-out stock Ethernet port, FE-551 is your best choice.

Our FE-551 works with 10Base hubs or 100Base switches because it is auto-sensing and will adjust the transfer speed to the incoming traffic. The card's 32-bit bus mastering mode gives you higher processing speeds by reducing the burden on the CPU. You'll be blaze through file transfers with ease and confidence.

The FE-551's Plug-N-Play jumper-less design allows for an easy installation by automatically configuring itself to the existing hardware. In addition to compatibility with Mac OS, the FE-551 is also compatible with all Windows OS.

It's time to change gears and get in the fast-lane with the FE-551 Fast Ethernet Card.
