PA-RISC 8500 360 Mhz Upgrade

[Americo]

Hi,

I have a HP9000 N4000 server with 4 processors PA-RISC 8500 360 Mhz.

I want to upgrade all the processors with new ones.

It's possible to upgrade to PA-RISC 8600 or 8700? Changing processors is enough or i'll need an upgrade kit?

Thanks for the help.

Hi Americo,

You will need an upgrade kit A5866A
Processor upgrade kit - Includes one 550MHz PA-RISC 8600 processor with 1.5MB cache and attached heat sink

What is the model number on the server?
A3639A
or
A3639B?

The A revision can only accept 360 & 440 MHz CPUs.

The B Revision can also accept 550MHz CPUs.

To use the 650MHz or 750MHz (8600 or 8700) you will need to upgrade to a C revision (also known as an rp7400)

The upgrade product # for that is A6750A.
