Upgrading UltraSparc III processor board to UltraSparc IV on 15K

Can the UltraSparc III processor boards on a 15K server be swapped out and upgraded to the UltraSparc IV processor boards?

Also, can MIXED processor boards be used on the 15K? In other words, can I use both UltraSparc III and IV boards on a 15k?If so what are the parameters? Are separate domains necessary for each processor type?

Thank you!

Terry

Terry,

Contact Sun, directly and open a service case.

... else contact your Sun account representative.

These forums are NOT hosted for issues on anything larger than a V1280/E2900.

Your SF15k question would be best answered by Sun.

You spent good money to acquire it and seem to be about to invest another good chunk-of-cash to upgrade it.

Take advantage of the service contract that is in place.

Don't hope for definitive answers from a public user-to-user forum.

I had a question like this from a 12k customer and I provided the info from the public handbook:

<a href="http&#58;&#47;&#47;sunsolve.sun.com/handbook_pub/Systems/SunF ire15K/components.html#SystemBoard" target="_blank">http://sunsolve.sun.com/handbook_pub/Systems/SunFire15K/comp onents.html#SystemBoard</a>

Mixing of US III, US IV and US IV+ is supported, but there is no information external to Sun, furthermore we recommended that the customer contact Sun directly, from what I understand upgrade work on these systems is to be carried out by Sun FE only ( like Bill! ). As Bill suggested use your support contract to confirm upgrade options for your system.
