2. Install the new buffer board.

a. Place the buffer board where the SCSI interface PCA was located previously (see

Figure 8).

Note: The buffer board is narrower than the SCSI interface PCD. Align the buffer board to the right

side of the module as you face the module from the back of the jukebox so that the external

connectors of the board align with the openings in the module.

b. Secure the buffer board with 4 of the screws that previously secured the SCSI interface

PCA (see Figure 8).

c. Discard all terminators (including the 68-pin terminators) from the obsolete SCSI

interface PCA.

WARNING: Do not reuse the terminators (including the 68-pin terminators) from the LUN

board. They are high-voltage differential (HVD); the new equipment can use only

low-voltage differential (LVD) terminators or single-ended terminators.

3. Connect the power cable to the buffer board (see Figure 8).

4. Add the new label to the LUN module to identify the ports on the buffer board.

5. Reconnect the cables previously disconnected from the power distribution card.

Note: There will be one cable left unconnected in the bundle of cables that connect to the power

distribution card. It is a multi-colored wire with a 12-pin offset, black connector.
