b. Replace and tighten the 2 T-20 (RLG) screws that mount each side of the drive enclosure.
Plug the drive cables into the interposer PCA in the following order:
1 - drive interface cable (use the one UNDER the SCSI cable connector)
2 - SCSI cable
3 - fan power cable
4 - power cable (over the SCSI cable)
Use the drive cables mounted on the upper interposer PCA as a guide.
Note
If you are upgrading this jukebox to a TOTAL of 8 drives or
10 drives, you must plug a capacitive load (terminator) to one
of the SCSI cable connectors on the lower interposer PCA. If
one already exists on that jukebox, use that one - do not add
the one from the kit.
If you are upgrading the unit to 12 drives, discard the
terminator if it is already mounted on that jukebox - the one
from the kit may be discarded also.
11. (If upgrading to an 8-drive jukebox.) Plug the capacitive load (terminator) into one of the lower
two connectors on the lower interposer PCA.
