There is no circumstance I know in which it is acceptable to see a continuously-burning red LED anywhere inside the Mac Pro case. They're used to indicate memory failure, over-heating, etc.
The situation was that I noticed a demonic cast to the interior of the case study machine as I could see the glow from the LEDs on the back of it. I was inspecting it because the fans were blowing hard and they had no reason as the computer hadn't been doing anything. On opening the case, eight LEDs were lit for each of the new DIMMS to increase RAM and there was another one lit on the back of the case. The one on the back was not near the processor so I assumed it had something to do with the fans.
The machine was shut down and the SMC (System Management Controller) was reset by unplugging the power cord for fifteen seconds then plugging power back to it and restarting it. (A different process is required for other Apple models)
On restart, the LEDs were out and the fans were not spun up again. After an hour or so the machine remains stable.
Odd details:
- All of the LEDs for the RAM were lit but the machine was not crashed (i.e. the RAM still worked).
- The heat sinks for the new DIMMs are significantly smaller than the ones for the original DIMMs. I attributed that to evolution in design but it also might be bait-and-switch from eBay.
- The machine ran continuously from when the DIMMs were installed until this morning. If the problem is overheating, it takes quite a while to get there. However, the new processors will definitely make it hotter and that's probably also true of the new video card.
- It's conceivable blowing the dust out of there had something to do with it. The blower was creating mighty gusts but that still won't get every dust molecule out of there. Rust never sleeps ... and neither does dust. Therefore, blow it out again during the Part II procedure.

The processors will arrive today. It's not so clear when the video card will arrive. According to the project plan, the video card should have arrived first as that progression is clear. The video card installation is not a complex process so it's good to eliminate it before going for the Big Tamale.
(I have no idea about the relative sizes of tamales. I doubt I would recognize a tamale if I saw one.)
The processor aspect is spooky as that's a One Way Out situation. If you fail going forward, it's not likely there will be success going back so it's mandatory to make it work or the machine becomes an ashtray.
The project plan can be modified to let the processor installation go first. The steps aren't dependent, it's just preference. There will definitely be video shot of the fiasco as it unfolds. Maybe I will even start the other camera as this could be a total horror show and those must be recorded. Hey, y'all, watch this.

Thats not the NEW machine is it?? ML
Nope, this is a rescue mission. As it sat, the computer was worth, tops, $250 and that would be from a generous buyer. When I'm finished, it will be a good and competent machine. Yevette has frequently mentioned an interest in working with video so the upgraded machine will be able to do it and in a sprightly manner too!
