Presto Gigabit Pro PCIe supports gigabit speeds over common CAT-5 cabling, so costly cable replacement is unnecessary. If your computer already has onboard Gigabit Ethernet, you can add a Presto Gigabit Pro PCIe and use it for dedicated connection to a printer, AirPort® Extreme base station, DSL or cable modem, or a video server, while leaving your onboard Gigabit Ethernet port(s) available for other connections.
Presto Gigabit Pro PCIe is compatible in Mac Pro, and Power Mac G5 & Xserve(2) & PCs with a PCI Express (PCIe) slot. Offering simple configuration, this Sonnet card is easy to use, and its support for 1000/100/10BaseT auto-negotiation and full/half duplex communication enable it to be used in most networks.
