4.6 Chassis Installation
4.6.1 Airflow
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the IMB-Q354 must have air vents
to allow cool air to move into the system and hot air to move out.
The IMB-Q354 must be installed in a chassis with ventilation holes on the sides allowing
airflow to travel through the heat sink surface. In a system with an individual power supply
unit, the cooling fan of a power supply can also help generate airflow through the board
surface.
4.6.2 Motherboard Installation
To install the IMB-Q354 motherboard into the chassis please refer to the reference
material that came with the chassis.
4.7 Internal Peripheral Device Connections
This section outlines the installation of peripheral devices to the onboard connectors.
4.7.1 Dual RS-232 Cable Connection
The dual RS-232 cable consists of two connectors attached to two independent cables.
Each cable is then attached to a D-sub 9 male connector that is mounted onto a bracket.
To install the dual RS-232 cable, please follow the steps below.
Step 1: Locate the connectors. The locations of the RS-232 connectors are shown in
Chapter 3.
Step 2: Insert the cable connectors. Insert one connector into each serial port box
headers. See Figure 4-12. A key on the front of the cable connectors ensures
the connector can only be installed in one direction.
