Installing more CPUs

[Tim Medford]

Greetings all.

We have an old K210 server that we have shutdown for good. I've removed all the parts that are worth anything and plan to hang on to them as spares (ie. memory, cpus, internal drives, power supply, etc...)

I would like to take the 2 CPUs from the K210 and put them in a K420 server running HPUX 11.0. They are the same CPUs as far as HP part number and clock speed (PA7200, 120mhz). This would bring the K420 up to 4 CPUs, which is its max capacity.

Is there any trick to pulling this off? I assume a full power-down, plug them in and power back up? Is there anything I need to do within the OS to see those new CPUs?

Thanks in advance,
Tim

I recently added 2 processors to my K460 (it had 2 to begin with), when the machine came up it recognized all for and according to glance it is using all 4 also. All I did was plug them in (in numerical order of course!)

Yep, there are tricks..............

1. Check the power supply part numbers for the two different models of K4xx series. Sometimes adding more CPU's will change the power requirements and require a beefier power supply.

2. As far as that goes, ask your CE about what you intend to do and check this out with them. Failing that, move this post to the HP 3000/9000 server section and post my first question. Those members of the server forum whose paychecks have HP imprinted on have access to all the internal info about this. Failing that, call your trusty 3rd part refurbisher of HP parts (Abtech, Blue Line, etc. see www.3k.com under vendor listings) and ask them for a quote on upgrading the box to 4 processors. They will make sure the quote contains all the parts necessary. Grill them on power supply issues, etc. (Forgive me Danny, but you guys *are* good at it)

3. Be advised that the rubber baby buggy bumpers on the cover which goes over the CPU's is VERY necessary to ensure a good tight fit to the backplane. No cover with rubber bumpers, no boot.

4. Be damn careful with ESD protection.
