CPU revision A or B?

I have an RP5470 with 1 processor in it at a remote location. I'm in the process of adding 3 more processors but I'm being asked if the existing processor is revision A or B. I don't have access to popping open the top and looking at it. Is there any other way to find the info? I've check stm and get the following info:

Re: CPU revision A or B?

I would guess the question is if you have a

systemboard

of revision A or B, right? Please confirm!

Hope this helps!

Torsten.

Re: CPU revision A or B?

Hi Torsten,

The initial request I received was "What rev level are your current processors, A or B?"

But after reading numerous posts on here I'd have to believe they really mean the system board revision, not the cpu..

The system board comes up as revision A14135 so that would mean it's a Rev A right?

Re: CPU revision A or B?

Okay, this is what I was just told. They need "the actual CPU version"

Wouldn't that be a PA 8700????

Re: CPU revision A or B?

I know several CPU revisions, e.g.

PA 8700 CPU Module 2.3
or
PA 8700 CPU Module 3.1

but what really matters on a L3000 server is the system board.

Only the B board can serve CPUs up to 875MHz, A is limited to 550.

Go to SAM -> performance blabla and get the actual MHZ rate of your CPU first.


Without checking I would assume you have an old firmware currently - need to check this.

The part# of the system board (from stm) will tell the revision (not in clear text, but the part# is unique).

Hope this helps!
Regards
Torsten.

Re: CPU revision A or B?

The processor is 750 Mhz so the board must be REV B.

I was told "remove the top cover and and the proc cover under that, the proc has a purple cover on it,record the numbers on the stickers on the purple cover"

I've never had to do this before when ordering processors but I'm now dealing with a new vendor and I can't get to the server b\c it's in a different state.

Re: CPU revision A or B?

I have never seen any purple parts in a l-class and I guess if you see some, they are at a wrong place ...

If you have a 750 Mhz CPU and you want a CPU - you need another 750 Mhz CPU - that's it. If you have only 1 and want to add 3, you need another processor support module.

Hope this helps!

Torsten.

Re: CPU revision A or B?

hi there,

just before you jump the gun on the system board theory.

if its a 750mhz cpu then there were actually 2 versions A and B A6805A and A6805B, this is probably why the reseller is asking, if there asking they must be good, as there trying to ensure you dont get a mix match.

Now, the A6805A has 1.5mb cache and the A6805B has 2.25mb cache installed.

not exactly sure how the cache is made up, but by your output you have 768kb inst cache and 1536kb data cache. if you were to add these this would give you the 2.25mb, but not sure you do? you could just use the data cache?

The only other way i could think of is, i seem to remember that you could get the FRU part numbers from the GSP, possibly something like the df command? or possibly run the infolog tool on the system option, usually top of the list in STM. this lists all the part numbers of the system boards, but not sure if it lists the cpus part number, but worth a go

dont also forget you will need another processor support module for the extra cpu's

will think abit harder!

Re: CPU revision A or B?

hi,

this doc lists both cpus and has info about mixing them, but not much

http://h18000.www1.hp.com/emea/presalessupport/downloads/June_bulletin_2006.pdf

do a find on A6805B

Re: CPU revision A or B?

Thanks Andrew for this input, the discussion was just to generally up to this point ... the real CPU details we identified during this discussion.

We just need to talk about ...

Hope this helps!

Torsten.

Re: CPU revision A or B?

Meanwhile I checked the firmware.

You have 42.19 installed, latest available is 44.12.

ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/PF_CARIW4412.txt
ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/PF_CARIW4412.tar.gz

There are also 'swinstall' suitable patches, did we talk about the OS already ... ?

Hope this helps!

Torsten.

Re: CPU revision A or B?

"I have never seen any purple parts in a l-class and I guess if you see some, they are at a wrong place ..."

CPU's in an L Class, (rp54xx,) have purple 'caps', and the N4000, (rp7400,) have black 'caps'. I have switched these back and forth between the classes, and the system doesn't know the difference, even though the part numbers are different.
