Airflow Direction in the MX10008 Router
The air intake to cool the chassis is located on the port (line card) side of the chassis. Air flows into the
chassis from the ports in the RCBs and line cards, through the switch fabric boards (SFBs), and exits from
the fan trays and the power supplies. This airflow is called port-to-FRU cooling or airflow out (AFO). See
Figure 23 on page 52.
