IBM 2104 Model DU3 - Manual (Page 31)

Reinstalling the Disk Drive Modules and Dummy Disk Drive Modules
Attention:
v Disk drive modules are fragile. Handle them with care, and keep them well away
from strong magnetic fields.
v 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.
1. Referring to the note that you made about the original locations of the disk
drive modules, reinstall the disk drive modules (in the same sequence that
they were removed) as described in the following steps.
2. Refer to Figure 10.
3. Ensure that the handle 1 is fully open on the disk drive module that you are
going to install.
4. With one hand giving support to the base of the disk drive module and the
other hand holding the handle 1 , insert the disk drive module and push it into
the slot.
When the handle touches the front surface of the enclosure, the module stops.
Note that the disk drive module is not yet fully home.
