P840 controller and cache battery connection

[LehcimB]

I pulled a P840 from a ProLiant G9 along with the cache battery backup. These are usually hooked up through the main board, so the problem is when you want to run them outside a ProLiant, the cables don't match so you can't directly connect the battery to the cache.

Is there a way to convert this or do I need a different battery?

There is no such standard option or long cable to connect this 96W battery outside.

In Gen9 there is a dedicated port, behind the drive backplane where you place this battery and connect into the system board connector.

Thanks for the response. Just to be clear, the P840 has no battery backup option whatsoever if not installed in a Gen9 (or up)? Not even with a different battery?

This controller is supported with Gen9 only, and as per quickspecs 96W battery is only supported option available.
