The adapter plates can be installed in either a flush or a recessed configuration of up to 3.8 cm (1.5 in.).
The SSA switch can be configured for air intake on either the chassis switch I /O port side or the power
supply side. Adapter plate installation must align the adapter plate ears with the air intake side of the
chassis.
If you have not verified the power supply and fan module airflow for the chassis you are installing, see
Power Supply Airflow and Switch Fan Module Airflow
direction for your chassis before installing the adapter plates.
If the current fan module airflow direction does not match the intended chassis airflow direction, see
Reversing the Fan Module Airflow
To install the adapter plates, follow these steps:
1 Place the adapter plates on each side of the chassis with the ear end toward the air intake side of the
chassis, ear flange pointing away from the chassis.
Figure 23 shows the correct orientation for a chassis with airflow from switch I/O port side to power
