5. Refer to Figure 11.
6. While continuing to push the disk drive module into the slot, slowly close the
handle 1 until it stops with a click. This action pushes the module fully home.
7. Verify that the disk drive module that you have just installed is aligned with the
sides of the 2104 and that no gap exists between this module and the modules
that are next to it.
Verify also that the front edge of this disk drive module aligns with the front
edges of the modules that are next to it.
If the disk drive module is not correctly aligned, remove it (see “Removing the
Disk Drive Modules and Dummy Disk Drive Modules” on page 7) and reinstall
it (steps 2 through 6 above).
8. Repeat steps 2 through 7 for each disk drive module.
Attention: Any slot that has no disk drive module installed must contain a
dummy disk drive module. The dummy disk drive module ensures that the
correct airflow is maintained around the disk drive modules in the other slots.
