Hi,

The voltage errors are most likely the system board. Are all of the systems giving the same error?

Hi !

Yes they do, basicly. The last one nagged one time about the second psu was not connected ????
And this one, seems not to boot normally the first time, have to  confirm that.
But the PG 1  and PG 3 complaint seems with all. Can you explain, where in the server I can find exactly those points, and which ports one the PSU's ? I'm electronics certified..

I also see two small daugherboards on the motherboard, that have a small coolplate, and have power mosfets mointed. I guess those do deliver the exact tension that is needed ? They are marked 7000805-0000 and CN-0K1115-56K-1114  A01
 
Number 4 is totally desmounted now, the motherboard is real dirty.
They used to be paletised, some pest made there way in...

Follow up.
Start that 2850 again, hangs in boot, about 1/8'st, is clearly not dead. Posts errors, checks for cd, starts it's boot, then hangs there. And doesn't continue anyhow.
I did clear it's NVram, still nothing.
Now I get following errormessages : 412 PG1 -5 V, PG3-3V, PG1-8V , Riser.
Took out the riser, didn't start up, gave error PROCC VTT What is Procc VTT ?
Riser in, start boot, hangs. Resetted mem, changed psu's, etc.

Age ? These servers weren't even used for a full 2 years.

Another 2850 reads the same errors, yet runs perfectly.  Didn't even ran 6 months.

Proc VTT is voltage regulators for the processor which should be a small add in part on these systems. It seems like these systems may have had some damage in storage.

Hello Josh,

I'll be downloading that app soon,

Thanks for your answers.I'm now busy to get win2008 64bit, but they say, that is for AMD's, opteron ??
Don't tell me, Poweredges need 32 bit versions ?

Concerning the support programs you have for Suse, I guess they should be running in opensuse as well ? rpm based.. Opensuse installs right away, and recognised everything right out of the box, as did an retired 2008 version for servers from Kubuntu ( I needed something on cd.. )
Then, I'm going to download everything I need from Dell, so, at least, I can read the logs.
I guess, with the logs, we can know a little bit more.
Now, I have two 1850's running, also with errors, but can't read them, but they work fine, also one 2850, also with errors, the reserve, complaints about 0212 PG 1 , PG3, Procc Vtt , 0412, Fan 7??? like all 2850's tested.
If I can't repair the boards myself, at least, I'll give it a try, is there an addy where I can send them for repair ? I understand, they are Foxconn boards ?
All their bios are  version A002, does it help updating these ? What do I win with it? Don't change what aien't broke.
Understand, I live now in a country with minimal support, for what I understand.

I need to get these working, then later, I'll be prolly in need of a real powerfull machine(s)

You can use 64 bit OSes. These systems are end of life, parts may be hard to find for repair.

You would want something with the third version of the system board.

Hi Josh,

That's true, eol they are, while kinda 'new' .

I kinda like them, for their SCSI setup, and I hate SATA, to much of these disks died on me.
So, I stay with scsi, and a little in the future SAS.
Is there any way, to get a manual for repairs on those motherboards ? I guess the PG 1, PG 3, Riser, and Procc complaints are mostly the add on cards ? If I could find out the normal voltage out, they arrange, and the pins out/in, I could rebuild those, or build a sturdier version. ( I'll be looking at the pin config of 604 sockets meanwhile )

On the other hand, if these boards are really inpossible to repair, I could find new/refurbished one, for very modest prices. Which version will support the dual core processors ?

btw, I'm really surprised, how much 1850/2850 are still is in use these days.

thanks in advance

Hi Josh,

sorry to bother you again, how to recognise those ?
I got the following on the dirty one : CN-OT7971-13740-57R-019D.........REV A04 Foxconn LS-36

I can list them all, but that will take a while ;)

thanks for the support

Steve

Anything with Rev A04 should work. 

Hello Josh

Thanks for your reply.
I have now installed windows 2003 enterprise server 64bit on an 1850, with REV 03 board, and like all 2850's, it has REV 002 bios.
Processors are all recognised as F43.
When I look into the internet, F43 should be a single core processor.
And here starts confusion. Linux, and windows recognises 2 core, and even show them in the operanting systems, with both running different tasks ( different load caracteristic )
Processors all run on 3.2Ghz, while they should then be single core ? Dual cores are said to run only 2.8Ghz ?
I did find a whole bunch of boards, with xC8306 marking, new in box, looking on the first usefull link, the declare it first generation, none dual core capable ?
My Rev 04 boards have code markings O(T7971), which should make them as well gen 1 boards, not comp with dual core, so I'm confused now.

Second question.
Like said, I have now installed a full version of 2003 running. Which Dell programs should I install, to be able, to read the error logs ?

As all boards have Bios Rev 002, does it make sense, updating the bioses ?
I'm waiting to read a detailed log, so I could get here inserted, and depending the result, I'll be taking the purchase decision.

To be sure, if I buy 'new' boards, for the 1850's, and 2850's, which part numbers should they be, to be dual core capable ?

Best regards,

Steve

Processor is single CORE, but it supports Hyper-Threading (HT), so the OS will actually see both "logical" processors even though there is only one "physical" processor. If you had both sockets populated, you would actually see 4 logical processors in the OS. HT was the predecessor to multi-core processors - it looks and acts like multi-core processors, it is just not as efficient or as powerful.

There exists a PowerEdge 2850 II ... ONLY this revision supports actual dual-core processors. This revision is NOT common. If I remember correctly, this model was only available for a matter of months before the 2950 was released, so there are few of them out there, few parts, and little documentation.

You should have all your hardware up to date. No reason not to.

Hi again Flash and Josh

A few extra questions :

-Which Dell programs to install to read the errors, that the led display can't ?
-Under windows, I keep having 3 'pci' items that keep being a problem to be recognised.
Probably one could be Drac,  the others I have no idea ?

- All these servers came with Nanya memory from Factory, but are 333Mhz rated.
Being 800Mhz processors, is memory busspeed then no 400Mhz ? So, they actually are limiting the processor capacity ?

I found this information about different generations:

Generation I system boards support up to two (2) Intel Xeon 64-bit single-core processors only. They will NOT support dual-core CPUs. Example Generation I part numbers for these system boards are T7916, T7971, C8306, and X7322.

Generation II system boards support all Intel Xeon socket 604, 64-bit single-core processors intended for the PowerEdge 2850 model in addition to the 2.8GHz dual-core Paxville processor with 4MB cache (SL8MA). The front of the system chassis is usually labeled with a Roman numeral "II" in the upper left corner above the LCD display. Example part numbers for generation II system boards are XC320, CD158, and NJ023.

So, If I can get NJ023's or XC320 , I'll be fine ?

I have now 5 Xeon 3.2Ghz processors, I guess, I use those double in the 1850's, and put dual cores in the 2850's.
Actually, these dual cores are more powerful, being 'only' 2.8Ghz ? While I know, even those won't soon be powerful enough no more. ( video recalculation , and pulling in subtitles ), and send on the fly

Steve

Typically newer processors with more cores at a lower clock speed will beat older processors with fewer cores but higher clock speed on benchmarks.

You should always install OpenManage Server Administrator (Managed Node, 32-bit) on your servers - it will probably also take care of the PCI devices you are seeing, including the DRAC if you have it installed. This will show you what is in the hardware log.

You can't change the system bus speed, but you could put memory in capable of using the full bus speed.

Hello both,


Thanks for the replies.
Well, that's be the way I'll go. I can get both the second gen. XC320 and NJ023 boards, and even new first gen T7971 boards, and those of 1850 2d gen as well
I also found dual cores, and get an offer for +30 Harddrive. Then these old guys are complete.

I dont want to change the busspeed, just give it the change to use it bus to the max.
I'm against the 'tuning'. The only thing I modded was the K6-II...
Concerning the slow memory, yes, I was already thinking to change them all to faster ones DDR400+
6 x 4 GB per machine  would do the trick ? I want ECC enabled..
