Replacing cache module on P840

Hi.  I'm a backup tech that resells the Axcient backup product which are HP ProLiant servers.  One in question has a P840 Smart Array Controller that, I'm being told by Axcient tech support, that the cache module is dead which makes sense because performance is degraded.  Unfortunataley, out of warranty.  Does anyone know if the cache module itself can be replaced or does the entire controller need to be replaced?  It looks like a separate module that is replacement in HPE Smart Array Controllers User Guide but I cannot find a part number for it.  Another guide shows that the P840 needs to be replaced and that the P840 comes with the cache module.  Thoughts?  Precautions?

I did this a few days ago on a server under warranty and the replacement part was the controller with cahe module.

Re: Replacing cache module on P840

Yes, replacement is simple ,remove the old one and install the new controller.

if you just want to replace the cache module then swap the cache module from new controller to your existing controller.
