If installing multiple switches, repeat steps 1 to 4 to mount the switches
following your rack plan.
Wherever the switch is located, be sure to pay close attention to switch cooling
requirements. The location should be well ventilated and provide unrestricted air
flow at the front, back, and sides of the switch. If the air flow is insufficient, it may
cause the switch to overheat and possibly fail.
The switch includes two removable fan trays located in the rear of the switch. The
fan tray options may have either a front-to-back (F2B) airflow direction or a back-to-
front (B2F) airflow direction. For proper switch cooling, all installed fan trays must
have a matching airflow direction.
The following figure shows the airflow through the switch.
