Add on Module for PERC 3/DC

Question

I've been looking around the support site for documentation with a parts breakdown of the PERC 3/DC to see what i have missing from the 3/DC controller that I have got.

In pictures that I have seen of the card there appears to eb a daughter board on the controller card just above the Cache memory DIMM. Can someone tell me what that daughter board is for? The controller that I have is missing this part. I haven't had a chance to power up the controller card yet to find out if it is working yet.

Thought someone here might be able to tell me what it is, and whether it is vital or an optional part.

Thanks

That is the battery pack for the cache module.  Without that module the controller is a Perc3/DC Lite.  This means that you can use the read cache, but not the write cache.

That's interesting. From the pcitures I've seen i had assumed that was what it was. But i took the DIMM out and there was a battery mounted onto the back of the DIMM module.

Have I got a different controller than what I thought I'd bought? The controller is marked as being a 9M912 which i believe is a PERC3/DC.

The part # you supplied is for the PERC 3/DC.

Well now I'v ehad a chance to stick it in a server and things dont look to good. The server recognises the device on boot up ans displays the PERC title page with BIOS revison (3.17)
Then does:

Initializing

Scanning for devices

Reading Configuration

Where it pauses for quite some time and eventually comes back with

Adapter at Range F000H is not responding
No adapter

I guess this means it knackered, unless there is a way of resetting it?

Try moving the Perc to a different slot, disable unneeded system board devices. Be aware the Perc 3 will not be very fast.

Server only has a single PCI-X slot. Thanks.
