Step 8.
Replace the IO board –
Hold the back of the board in an elevated position,
angle the board at a slight angle to the controller module and gently slide the
host IO board into the controller module (see
Figure 2-5
). First ensure that the
front panel interfaces are correctly aligned with their respective locations on the
controller module rear panel. Next, align the board to board connectors with
from the host IO board with those on the controller board. Gently push down on
the controller board ensuring a proper connection between the board-to-board
connectors.

Step 9.
Re-install the optional BBU with the charger board –
If an optional BBU
module was previously installed, both it and its associated charger board should
be re-installed now. Detailed installation instructions for the BBU installation
procedure can be found in
Section 2.7.2
.
Step 10.
Re-insert all the retention screws
– Re-install all the retention screws that were
removed from both the rear panel interfaces and the host IO board. Note that if
these retention screws are not reinserted, the host IO board will not be properly
secured to the controller module. It is therefore imperative that all the retention
screws that were removed are replaced.
Step 11.
Reinsert the Controller Module –
If an optional BBU module is not going to be
installed, the controller can be installed.
To install the controller
align the
controller module with the controller bay and gently slide it in. Once has been
fully inserted into the rear of the subsystem, close the rear flaps and secure the
controller module to the ES U16U enclosure by
tightening the hand retention
screws
on the back of the controller module. (For more detailed instructions
please see
Section 2.8
)
