When LSWM1FANSC/LSWM1HFANSC fan trays are used, cool air flows in through the air vents in the fan tray panel and the
power supply panels, circulates through the chassis and the power supplies, and exhausts at the network port side, as shown in
Figure 51: Airflow through the HPE 5900AF-48XG-4QSFP+ chassis (with LSWM1FANSC fan trays) on page 72.
