Previously we talked about it, how to substitute the BBU batteries for HP SmartArray P400. Today we show the same regarding HP P600 RAID controller. This is how the battery (weel, accumulator) looks like this:
There are several choises: purchasing a new battery from Ebay, substituting charge elements inside of the battery, or our way – add external accumulators. Very naturally, doing this invalidates any real or imaginable warranties from HP. Here you see what is inside of the battery corpus after you take it apart:
You should take the original elements out of the battery:
Most important task is to find some suitable batteries for the substitution. We took the risk and purchased accumulators with twice as much of the capacity as the original ones. Our source for accumulators is http://www.ristart.ee :
Next step is to prepare a PCB which will carry the the golden contacts. Contacts are separated from the original accumulators by means of a sharp knife. The resulting PCB will look approximately this:
The whole building block is to be hardened by means of the glue gun:
A P600 controller actually needs two batteries, thus the resulting buildup will look like this:
This is how the P600 looks like after the modification:
It is neccessary to find a suitable place for the batteries inside of the computer case:
Use two-sided tape to fasten the batteries:
This is the resulting picture:
Last but not least – power on the computer and let batteries load. On the picture below, batteries are still empty and thus the cache is not usable yet:
It’ll be wise to update your controller firmware. Unsuccessfully I cannot give any hint here, because HP has recently decided to bill the access to upgrades.
Vaat siis, mis oli karul kõhus!
