Hi
I operating two Fujitsu Eternus3000 model 50.
2 weeks aog, the replacement period of BBU(Battery Backup Unit) of
Eternus storage was expired. So I purchased two BBUs

but problme is I don't know how to replace.

I want to know flowings,

* Can replace during storage running ?
* It need some additional works before / after replacement BBU ?
* If that, what is the additional work? it's such very technically
hard that must require the support of engineer.
* Or replacement BBU is just that remove old BBU and insert new BBU?

i expect your replies whether is good or bad information.

Thanks...
