SUPERWORKSTATION 7033A-T Manual
3. SATA backplane:
All four SATA drives plug into the SATA backplane. There are two
jumpers and two headers on the SATA backplane, as noted below. A
ribbon cable from JA1 on the motherboard should be connected to the
JP26 connector on the SATA backplane. There are also two power
connectors on the backplane - both should be connected. See Figure 6-6
for the locations of backplane connectors - the reverse side of the
backplane has four channel connectors that the SATA drives plug into
when inserted with a SATA drive carrier. See Figure 6-2 for drive
number configuration. You cannot cascade the SATA backplane.
