Bring an old Mac Pro 4.1 to life
Hi,
I have another post about upgrading to a dual processor from a single processor, but I think I may have jumped the gun a little bit.
Background:
I received a MacPro 4.1. It is a company cast-off, and hasn't been used in at least 6-7 years, from what I was told. There was a post-it note on it that said "start up bong, but no picture".
The machine looks OK from the outside. It has a scratch on the left side (the side that opens up), and some nicks and very small dings. Otherwise looks fine. I opened it up, and aside from being totally blown away by the build quality, looked the unit over. It is a single processor unit, it has 3 X 2GB Memory modules (DDR3-8500), and is fairly clean inside, but does have some dust. It has had all of its drive sled removed. Graphics card is a GT120.
Just for completeness, the GT120 has one mini DP port, and one DVI DL port.
Current status:
As per the post it note, it does have a start up chime, and the monitor I am using (a 27" HP) did have its front panel LED go from amber to blue (indicating sync up). There is no display of any type. I did have a wired Apple keyboard and mouse connected to the front USB port. After powering it on and off a few times, there was no chime any more (I was trying various things, like using the mini DP port instead of the DVI port, rear USB ports instead of the front panel USB ports for the keyboard, etc.)
Observations:
1. The GT120 is in the top PCIe slot. All of the documentation shows it in the bottom slot. When I look at the motherboard, it calls the top slot X4/Raid, and the bottom slot X16. Should the graphics card be in the bottom slot?
2. There are other threads that I looked at before posting this. They seem to indicate that there should be diagnostic LEDs lit up. There are none on my unit. I do get a brief red LED lighting up on the CPU tray when I power it up. Does this indicate a bad backplane or CPU tray?
3. I did download the Apple user manual. It says that startup issues are sometimes caused by the on-board battery. Considering the amount of time the machine was turned off, and the low cost of a 2032 battery, I think I am going to change that out as a first step.
Sorry to all who think this is basic stuff. This is the first Mac Pro I have been up close and personal with. I play with PCs all the time, and have 3 other Macs that I use regularly (along with other Apple devices). I have really never seen any Mac Pros outside of an Apple Store, and I have to try and figure this out, but without a display of any type, it isn't easy on an unfamiliar system.
