Cooling system
The cooling system of the switch includes the ventilation holes in the chassis, fan trays, and built-in fans of power supplies. To
guarantee that this cooling system can effectively work, you must consider the site ventilation design when you plan the
installation site for the switches.
HPE 5920 cooling system
The fan trays in the HPE 5920AF-24XG and 5920AF-24XG TAA switches must be the same type: LSVM1FANSC or
LSVM1FANSCB.
• When LSVM1FANSC fan trays are used, cool air flows in through the air vents in the fan tray panel and the power supply
49: Airflow through the chassis (with LSVM1FANSC fan trays) on page 70.
• When LSVM1FANSCB fan trays are used, cool air flows in through the air vents in the network port-side panel and the
power supply panels, circulates through the chassis and the power supplies, and exhausts through the air vents in the fan
tray panels, as shown in
Figure 50: Airflow through the chassis (with LSVM1FANSCB fan trays) on page 71.
