Install and cable the buffer board(s)
To install and cable the buffer board(s):
1. Place the buffer board where the SCSI interface PCA used to be (see Figure 5).
Note: The buffer board is narrower than the SCSI interface PCA. Align the buffer board to the right
side of the module as you face the module from the back of the jukebox.
Figure 5: Buffer board
2. Secure the buffer board to the module.
■ If you have a 4-drive or 6-drive jukebox, use 4 of the screws that previously secured
the SCSI interface PCA (see Figure 5).
■ If you have a 10-drive jukebox, use the 4 standoffs (supplied) to secure the buffer
board to the module.
This buffer board connects to the upper interposer board.
3. For a 10-drive jukebox:
a. Stack the second buffer board on top of the first buffer board.
b. Use 4 of the screws that previously secured the SCSI interface PCA to secure the
second buffer board to the standoffs.
This buffer board connects to the lower interposer board.
WARNING: Do not reuse the terminators from the SCSI interface PCA. They are
high-voltage differential (HVD); the new equipment can use only low-voltage differential
(LVD/SE) terminators supplied.
4. Connect the new internal orange and white LVD SCSI cable(s) to the buffer board(s).
5. Connect the power cables to the buffer board(s).
6. Route the LVD SCSI cable(s) through the cable access slot on the left of the module (see
Figure 5).
7. Reattach the buffer board module to the jukebox using the 4 T-20 torx screws previously
removed.
