Step 1. If you are installing a module into a 2104 Model TU3, open the front cover
(see “Cover” on page 68), if not already done.
Step 2. If you are installing a dummy disk drive module into an empty slot, go to
step 3.
If you are installing a disk drive module into an empty slot, go to step 7 on
page 82.
If you are installing a disk drive module into a slot that already contains a disk
drive module or a dummy disk drive module, remove that module (see
“Removing a Module” on page 75), then go to step 7 on page 82.
Step 3. Refer to Figure 30.
Step 4. Insert the dummy disk drive module into the slot and push it fully home.
Step 5. Verify that the dummy 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 module
aligns with the front edges of the modules that are next to it. If the dummy
disk drive module is not correctly aligned, remove it then reinstall it.
Step 6. Repeat this procedure for other dummy disk drive modules, or go to step 7 on
page 82 to install disk drive modules.
