I was having trouble with an ethenet card and had to replace it. When I put the card into to the slot and turned on the mac I noticed a red light on above the power supply...and my new ethernet card still didn't work. I installed the software for the card and still nothing but the red light and my fan running a bit faster than normal. I don't know if I did something to cause this red light to come on or what, but it's driving me crazy!! Please help me.
Red means STOP! Apparantly something is not connected right. I have never gotten the red light, except on my PC, so I couldn't tell you much more on it.
Thank you to all who posted replys to my problem, but I've found a solution. There was a white sticker on the rear plastic foot that had been scraped off a bit and it was messing something up...sitll not sure how that works. As soon as I did what Bob mentioned my problem was solved. Read below in blue
Thanks,

My situation was simple. The "Drive bay fan" goes to high speed on power-up and stays that way and a red LED seen through the case just above the power switch lights up. Apple replaced (in total) the Main Logic Board (MLB), both processors, the two CPU "Intake fans" and the fan next to the speaker. At this point the problem still existed. During the "Fan Calibration" process the "CPU Intake fans" were reporting to be too high which produced an error by the Apple diagnostic software the tech was using (not software the general public has access to) stating something along the lines that the plastic inner door was off, to check it and re-run the test. Everything was in its place, nice & tight.
After several trips out to my house (I'm disabled & on-site AppleCare was very much needed), the tech once again mentioned the red LED I had pointed out to AppleCare several times, this time the AppleCare rep looked into it and here is what took place to troubleshoot the LED/Drive bay fan issue.
Open your side case and see if you have a red LED on, if not, this may not be of help. If the LED is on, remove the clear plastic door and you'll notice that the rear tab has a white sticker covering it. Take a piece of white paper twice the width of the rear slot where the plastic tab goes and fold it in half to make it thick (think of bearking a beam of light, thin paper may not do the trick). Now stick the paper in the rear slot (***HOLD ONTO IT***), if the LED stays on then (in my case) you need to replace the "Airflow Detector Board"
Hope this helps.

Reason: words mispelled
Mac Specs: PowerMac G5 Dual 2GHz (June 2004), 2.5GB, Airport, black 5G iPod 30GB, white MacBook 2.0 2GB
You didn't tell us that your fans were blowing full blast, which would tell us that either the air deflector wasn't in place or, like in your case, the little white tab is gone or damaged. :cool: Worst case would have been a defect airdeflector sensor. of course.
With the right information, you'll get the right help.
But I presume your Ethernet card still doesn't work, as that problem has nothing to do with the air deflector.
I had the same problem today where the same red light inside the housing of my Power Mac G5 1.8 Ghz came on. I was befuddled at first because of the light and because the fan was louder and running more continuously than usual. That's when I noticed that, in my haste to put my computer back together after having added RAM, I forgot to put back the clear, large air/vacuum sealer that goes on right before you seal the unit with the metal door. I turned my computer off and disconnected it, then I removed the metal door, replaced the clear, transparent seal, and then replaced the metal door once again and I restarted my computer: the red light was no longer on and it sounded and functioned as it normally does once again.
