May I work with 3 processor in a rp5470_?

Hi, I need to know if I can have three processor working in a rp5470. Actually I have one.
And may I install them without shutdown the server rp5470. What about the rp5430, can I install another processor in a rp5430 without shutdown the system_? I heard about the Dynamic Processor Deallocate.....

You must shut down the system to add more processors. You can have any number from 1 to 4 processors in an rp5470, and either 1 or 2 processors in an rp5430.

1) In rp5470, you can have up to 4 processors working at the same time.

2) Yes, the system is capable of doing dynamic processor deallocation with HP-UX 11 loaded. You can remove a working CPU when the system is online.

3) In rp5430, you can have up to 2 processors.

4) Even in rp5430, dynamic processor deallocation is supported.

Read about dynamic processor deallocation here:

These are the rp54XX product details:

Hi,

when you add third processor to the system,
you should have second Processor support
module present in the system. One PSM
supplies power to 2 cpus.

Hi Shiju,

I stongly feel you cannot plug in a processor
when system is live. The dynamic processor
deallocation feature may be for the processor
already plugged.

Not sure, can some one from HP clarify??

I personally would not plug another processor into a live system purely from a saftey aspect :-) John.

"Caution: DC voltages are present when the server is connected to AC power. Do not install or service rp54xx internal components while DC voltage is present. Failure to observe this precaution can result in damage to the server."
