2.9.1 About Daughter Board Installation
♦ The optional, separately purchased daughter board allows you to add an additional
four SCSI-320 I/O channels to the SR controller.
♦ The daughter board, like the controller board, is a very sensitive component and must
be treated carefully. All anti-static precautions must be strictly adhered to and all the
controller safety precautions observed.

Step 1. Remove the chassis top cover. Before installing the daughter board,
remove the chassis top cover. For further instructions on how to remove
the top cover, please refer to Section 2.6.2.
Step 2. Install the daughter board. The daughter board is mounted on four pre-

front of the SCSI connectors. Place the daughter board onto the docking
connectors so that the retention screw holes on the daughter board are
clearly aligned with the spacers.
