Step 18. Refer to Figure 78.

Step 19. Lay down the module so that it rests on the supports 1 .
Step 20. Attention: All slots must contain either a disk drive module or a dummy disk
drive module. Any slot that has no disk drive module installed must contain a
dummy disk drive module. The dummy module provides continuity of the SSA
string, and ensures that the correct airflow is maintained around the disk drive
modules in the other slots.
Go to "Installing a Module" on page 156, and install a disk drive module or
dummy disk drive module, as required.
