Mystery SCSI Hotswap component.

've recently purchased some second hand SCSI components including an
ASUS PC-200 card (Rev1.2), adaptors to allow a 68pin cable to be
attached to a 50pin connector and two Seagate Barracuda hotswap drives.

Included with the package was a mystery item which appears to have been
used in conjunction with the drives.

Its a small PCB with the following markings on one face:

Samsung

LVD SCSI B/P
PCB CODE:BA41-00052A
Rev/MP 1.0

On the same face there is a, four pin molex power connector, a female
68pin SCSI connector and a set of jumpers labeled JP1. Near that is
what looks like a power connector on a floppy drive and a pair of
switches.

On the other face there are two 68 pin connectors that fit to the
Seagate drives.

I am looking for any information on the card and its use as I would
like to use the Barracudas as backup storage.

Can anyone point me to where I could find a manual?
