Advanced Network Connection

Whether you need to add a third Gigabit Ethernet port to your Mac Pro® tower for improved performance, or step up to Gigabit Ethernet connectivity for your PC, get a Sonnet Presto Gigabit Pro PCIe Gigabit Ethernet adapter card for an advanced networking solution. This Sonnet card supports link aggregation(1) with your Mac's onboard Gigabit Ethernet ports, and full duplex communication to achieve 2000 Mbps transfer rates—the ideal solution for high-bandwidth data transfer requirements. Presto Gigabit Ethernet Pro PCIe also supports 9000 byte jumbo packet transfers (compared to 1500 byte standard packets) to support higher performance and reduced overhead when transferring large files.

Presto Gigabit Pro PCIe is compatible in Mac Pro towers and PCs with a PCIe slots. This card is also compatible with any Mac® or PC with a Thunderbolt port when installed is a Sonnet Echo Express or xMac™ Thunderbolt 2-to-PCIe card expansion chassis or other qualified Thunderbolt expansion system. Offering simple configuration, this Sonnet card is easy to use, and its support for 1000/100/10BaseT Usage vignette for Presto Gigabit Pro PCIeauto-negotiation and full/half duplex communication enable it to be used in most networks.


Key Features

Provides Gigabit Ethernet Connectivity to Mac Pro Towers and Windows PCs—Simple way to add or expand Gigabit Ethernet connectivity to any compatible computer

Simple Connection—Supports gigabit speeds on common CAT-5 cabling (no need for costly cable replacement)

Jumbo Packets Support—Supports jumbo packets (Mac and Windows)

Link Aggregation Support—Supports link aggregation with onboard Gigabit Ethernet ports (Mac only)

Full/half duplex

1000/100/10BaseT auto negotiation

Plug-and-Play Installation—Easy setup with Mac computers

Thunderbolt-compatible—Compatible with Sonnet's Echo Express and xMac lines of Thunderbolt 2-to-PCIe Card Expansion Systems


Presto Gigabit Pro PCIe supports gigabit speeds over common CAT-5e 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.
