4.5.1 Airflow
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the IMBA-Q454-R10 must have air
vents to allow cool air to move into the system and hot air to move out.
The IMBA-Q454-R10 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.
4.5.2 Dual RS-232 Cable with Slot Bracket
The dual RS-232 cable slot connector 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 slot. 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 4-10. A key on the front of the cable connectors ensures
the connector can only be installed in one direction.
