The Macintosh line of computers, has, for many years implemented quick, simple and powerful networking technologies years ahead of other computer makers.This post is about the dual gigabit ethernet ports that have been standard on the Power Mac G5 and the recent Mac Pro computers.  Apple led the field in 2000 by shipping its PowerBook and PowerMac computers with Gigabit Ethernet.

 Initially, gigabit Ethernet was deployed in high-capacity backbone network links (for instance, on a high-capacity campus network). In 2000, Apple’s Power Mac G4 and PowerBook G4 were the first mass produced personal computers featuring the 1000BASE-T connection.^[1] It quickly became a built-in feature in many other computers.

But Apple innovated again when they shipped the Power Mac G5 in June 2003 with Dual Gigabit Ethernet Ports, praise reigned on the Power Mac for this:

 The Power Mac G5 supports up to 16GB of 533-MHz DDR2 SDRAM and now includes two Gigabit Ethernet ports. Multiple Gigabit Ethernet ports are well suited for users who plan to utilize their Power Mac in an Xsan environment — that’s Apple’s storage-area network technology for high-performance computing. 

But, what can these dual ports do for us in our day to day computing? Well, simply put, your Power Mac can connect to your Router through both of these ports simultaneously and instantly double your network bandwidth.Many operating systems including Unix, Linux and Windows XP require intelligent configuring on the part of the user or the “System Administrator”, on the Mac, however, It Just Works.This trick will work for you even on your laptop, where a windows laptop would become confused with a WiFi connection as well as a Wired Gigabit connection, the MacBook will happily use both network connections simultaneously to get the most efficiency from your home router. Remember, the greatest home routers are the Apple Airport line of routers available from the Apple Store, Amazon or AuburnCom, your San Francisco Mac Evangelist!
