Appendix D Cooling system
The cooling system of the HP FlexFabric 5930 switches comprises the ventilation holes in the chassis, fan
trays, and built-in fans of hot swappable 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.
The fan trays in the HP FlexFabric 5930-/HP FlexFabric 5930- TAA switch must be the
same type: LSWM1HFANSC or LSWM1HFANSCB.
•
When 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 43
.
•
When LSWM1HFANSCB 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 44
.
