NovaScale R422 Installation and User's Guide
5-2 Serverboard Installation
This section explains the fi rst step of physically mounting the NovaScale R422 X7DBT/
X7DBT-INF motherboard into the NovaScale R422/R422-INF box (NovaScale R422/R422-
INF box (CSE-808T-980B). Following the steps in the order given will eliminate the most
common problems encountered in such an installation. To remove the serverboard, follow
the procedure in reverse order.
1. Accessing the inside of the system (see Figure 2-5)
The top cover of the chassis is secured with four screws: two at the top rear of the cover
and one on each side lip, also near the back. Remove all four, then place both thumbs in
the indentations and push the cover back until it slides off. You can then lift the top cover
from the chassis to gain full access to the inside of the server. (If already installed in a rack,
you must fi rst release the retention screws that secure the unit to the rack. Then grasp the
two handles on either side and pull the unit straight out until the rails lock into place.)
2. Check compatibility of serverboard ports and I/O shield
The NovaScale R422 X7DBT/X7DBT-INF motherboard in a Twin 1U con fi guration requires
the use of Bull's specially designed 1U Twin chassis: the NovaScale R422/R422-INF box
(CSE-808T-980B). Make sure that the I/O ports on the server boards align properly with
their respective holes in the I/O shield at the back of the chassis when installing.
3. Mounting the serverboard onto the serverboard tray
Carefully mount the server boards by aligning the board holes with the raised metal
standoffs that are visible in the chassis. Insert screws into all the mounting holes on your
server boards that line up with the standoffs and tighten until snug (if you screw them in
too tight, you might strip the threads). Metal screws provide an electrical contact to the
serverboard ground to provide a continuous ground for the system.
5-3 Connecting Cables
Now that the server boards are installed, the next step is to connect the cables to the
boards. These include the data cables for the peripherals and control panel and the power
cables.
Connecting Data Cables
The cables used to transfer data from the peripheral devices have been carefully routed to
prevent them from blocking the fl ow of cooling air that moves through the system from front
to back. If you need to disconnect any of these cables, you should take care to keep them
routed as they were originally after reconnecting them (make sure the red wires connect
to the pin 1 locations). The following data cables (with their locations noted) should be
connected. (See the layout on page 5-9 for connector locations.)

NOTE: Each connection listed should be made for both server boards in the chassis.
