We have 9406-825 machine and there's two(2) 5094 expansion unit (One for DEV and the other for PROD). When I changed the cache battery for DEV partition, I power down the partition, but the PROD partition also power down. What would be the possible problem of our machine? Does anyone knows how to solve the problem? It's the first time to happen it here. Before it was working properly, and when I down the other partition nothing happens to the other one. Please help me.
