P400i In Lock-up State after installing 512MB BBWC

[SeanCamby]

We have an older DL360 G5 (not currently under warranty).  It is at BIOS version P58 and has an internal P400i array controller with a 256MB cache module.  We needed to expand the RAID5 array with a 4th drive (currently shows as a spare).  From what I researched we needed to switch the 256MB module with a 512MB module (part number 405148-B21, 512MB BBWC).  After installing the 512MB module we get a post error stating "1783-Slot 0 Array controller is in a lock-up State due to a hardware configuration failure."  As a result the controller is disabled.  The firmware on the P400i is version 7.24.  I have made sure the cache mdule and cables are seated properly.  Reinstalling the 256MB module reenables the controller.  Not sure what else needs to be done/attempted.

The firwmware is the latest and the 512 cache is compatible, so you could try to reset the controller by doing following:

power down the server, install the 512 module, remove all drives (remember their exact bay position), start the server without hard drives - check if the 1783 error ist still there. 

Power down again, install the drives in their initial positions and start. 

If issue persists, the new 512 cache module may be defective.

Ok.  I will try that and see what happens.  Thanks.

I tried everything as directed and still got the 1783 error.  I was able to use the battery w/ its cable to attach to the 256MB module and got it working.  I will return the 512MB since I believe it is defective.
