Finding a Philosopher Stone

On last 7th June, I replaced an Internal Battery Feature (IBF).

The IBF is an option for customer to have it . It is a part of the power components in mainframe as use for power shortage.It was designed to keep the server up long enough to properly shutdown or to ride through short power outages. IBF is connected to Bulk Power Regulator (BPR).
The BPR function is to convert AC voltage to 350 VDC as supply power to whole mainframe components.

To handle IBF it required at least 2 persons. The Pb battery weight was more than 40 KG (if im not mistaken).

The IBF is seat on the top frame of mainframe. Depend to the model it can be in both Z and A frame or only in a single frame.
To install, it required a lift tool in order to lift it down and up to the top frame. Procedure to install the lift tools can be view during the R&V procedure. In the 2nd picture as below , the IBF already take out and will be lift down.
In the 3rd picture, the IBF is being lift up by the lift tool.
The lift gear need to manually turn until it reach the IBF cage. After the IBF was installed to the original location, follow the R&V to connected the IBF cable, switch ON CB, and powering ON the IBF. Once the success message appear , the R&V complete.



This is the old and new IBF. New IBF was 'Made In Malaysia' and proudly that now many of the mainframe components are made locally .
