Hot Plug Backplane

To install the backplane board when you are using an add-on SCSI controller
board, follow these steps:

1. Set the terminator switches on the backplane according to your planned

SCSI channel configuration. Refer to the “SCSI Channel Configuration”
section of this appendix for the channel configurations.

2. Remove all the old hard disk drives from the system, if any.

Note:  Make sure that you have already installed the Adaptec 2940UW
controller board before you proceed. Refer to the controller board
documentation for installation instructions. If you are not using the Adaptec
2940UW board, you can use the Mylex DAC960 disk array controller that
supports the RAID technology.

3. Install the backplane and secure it with eight screws. Refer to Figure D-9.

4. Connect three power cables into the connectors at the back of the

backplane board.

5. Connect one end of the SCSI cable to the channel on the Adaptec

2940UW board (or to your disk array controller board) and the other end
to the corresponding channel on the backplane. The figure below shows
how to connect the cables properly.
