Figure 105 Airflow through the chassis
(2) Front inlet air vents
(4) Outlet air vents in the fan tray panel
(5) Outlet air vents in the power supply panels
IMPORTANT:
The chassis and the power supplies use separate air aisles. Make sure that both aisles have good
ventilation.
A5820X-14XG-SFP+ (2 slots)/A5820X-14XG-SFP+
TAA (2 slots)
The A5820X-14XG-SFP+ (2 slots) and A5820X-14XG-SFP+ TAA (2 slots) switch chassis are 2U high and
use separate air aisles for their upper half and lower half. Make sure that the two air aisles have good
ventilation.
Figure 106 shows the airflow through the lower half of the chassis. Cool air flows in from the left
side of the chassis, circulates through the lower half of the chassis and the power supplies, and
exhausts through the air vents in the fan tray panel and the power supply panels.
Figure 107 shows the airflow through the upper half of the chassis. Cool air flows in from the left
side of the chassis, circulates through the upper half of the chassis, including the OAP card and the
interface card, and exhausts through the outlet air vents in the fan tray panel.
