Tyan S2885 won't turn on

I have a Tyan S2885 with a Antec TP2-550EPS12V power supply. Everything is hooked up according to the manual. Jumpers are for the most part in teh factory default position. When you press the start button (or short the power buttn pins directly) nothing happens. No fans turn (not even in the power supply itself).

What's going on?

Thanks in advance.

Your power supply is the wrong type. According to the Tyan site you need an EPS 12v  with  24pin and 8pin power plugs.
like this one  http://www.newegg.com/Product/Product.asp?Item=N82E16817703002
 If you use the one you have it may damage the board.

Sorry meant to say >EPS12v/SSI< power supply. note the SSI change.

Whoa there gay_sap3219. If this is the wrong power supply he can fry his motherboard and use it for a dinner plate instead. He may have already killed it if he has plugged one of those 6pin SLI plugs into the 6pin connector.

sparkmaker,  ignore gay_sap3219, he just registred today and is making non-sense posts, I mean stuff like:

"It is quite simple to insert a floppy disk into the drive.  i would recommend having a mexican at hand just incase something happens.  If he comes to no use, just have him mow your lawn." (see http://www.experts-exchange.com/Hardware/Q_21823464.html)

Can we have some more about your setup?
Do you have dual or single CPU's installed and what are they?
What is the make/model/spec of your memory chips?
.
The board only supports -REGISTERED- memory.
If you don't have registered memory it won't start.
.
If you have dual CPU's then each CPU has it's own memory controller.
If you don't have the memory in the correct slots then one CPU may have all the memory and the other CPU has none.
The Tyan blurb goes:
• Always install memory beginning with CPU0/DIMMA1
• In order to access memory on CPU2; both processors must be installed
• Single, pairs, or four modules are supported on each CPU
• Configure memory symmetrically on each CPU for best performance
• At least ONE Registered DDR SDRAM module must be installed for the system to turn on and POST.
• 128MB, 256MB, 512MB, 1GB, and 2GB* Registered DDR400#/333/266
• SDRAM memory modules are supported
• All installed memory will be automatically detected
• The Thunder K8W supports up to 16GB with two CPU's installed
-------------
* 2GB Registered DDR333/400modules not available at time of print
# DDR400 supported on Opteron™ 246 and higher

Dual Opterons.
Tried single and double memory sticks. One in the CPU0DIMMA1 slot, then one in that slot as well as in the othe one specified by the manual. Both of the sticks are registered DDR SDRAM. It was 2 sticks of 1GB.

Opteron model 244s.

Memory models: CMSS1GBR72-400 and CM72SD1024RLP-2700/S

Crucial does not list the CMSS1GBR72-400 as being compatible with your MoBo.

Tyan also does not list the CMSS1GBR72-400 as being compatible.
What I do keep seeing on it is: "For specific Dell, Compaq, HP, IBM, and Gateway Servers.".

To start it you are jumpering pins 6 and 8 on J86?

DrDamnitAuthor Commented:
Yes. PC Bonez, that memory seems to be 400Mhz, and I am not using an opteron 246 or above (see your previous post). If the memory is not supported, would that cause the board to not power up? In my experience, if the memory is inserted incorrectly, or not compatible, the board will power up, but will not post. Could that be the issue?

MarkCommented:
Check that PSU, if its not the type specified by the manufacturer -->EPS12v/SSI<-- you may have already blown the motherboard. This spec for the PSU has both 24 pin and 8 pin power plugs. If your PSU doesn't have both of these, especially the 8pin, then you have the wrong PSU in there. The manual is very explicit on this and warns not to use any other type. And if you do then they recind your warranty on the board.

Please specify if you have the proper PSU before you do anythng else.

The PSU has the 24, 8, and 6 pin connectors. I connected them all, they all fit easily (i.e., I didn't force it). Could it still be the PSU?

DrDamnitAuthor Commented:
It makes no mention of SSI, however....

MarkCommented:
Ok thats a relief, -->Server System Infrastructure (SSI) Is a Specification for servers,standardizing interfaces between components including boards, chassis, and power supplies.
The 6pin is not necessary unless you are using an AGP Pro 110W video card. Its for the extra power needed to run this type of card. What video card are you using. If its not an AGP Pro 110w card then the 6pin doesn't need to be connected.

In the manual from Tyan, Section 2-12 on page 26 gives instuction on the PSU installation. ftp://ftp.tyan.com/manuals/m_s2885_101.pdf

I'm wondering if the PSU is dead at this point.

PCBONEZCommented:
(The mention of the 246 was from a Tyan's info chart and left in for completeness.
- It only applies where the # marker is in the chart.)

You missed my point.
The CMSS1GBR72-400 is appearantly not compatible with your motherboard board.

MarkCommented:
And a fine point it was PCBONEZ. That could explain alot, but would it keep the PSU from even turning a fan?

PCBONEZCommented:
Please try it with a single processor and a single CM72SD1024RLP-2700/S module in.

@sparkmaker - On this board I 'think' that's a true statement. I just went through this on another similar board (sometime -this- month) where the asker had unregistered memory and it required registered. As I recall it was a also Tyan Opteron board but I'm sure it was at least a Tyan dual CPU board,,, but I can't seem to find the blasted question to verify my, um, memory...

DrDamnitAuthor Commented:
It's fixed! Not the board, I canned the board and got a different one. The memory was fine, the CPUs and the power supply were all ok. So, the problem is most likely that the 400Mhz memory with the Opteron 244s were not compatilble, and the board not only knew it, but didn't even turn the fans on because of it. Doesn't seem likely, but hey.....

PCBONEZCommented:
I agree with your "problem is most likely" senario.
That or something close is what I figured. Tyan boards can be unusually picky about memory.
It seems like they are just making things hard but I'm sure their real concern is a rock solid stable system once you get it built. Tyan does pretty well at that.
