Cisco Catalyst 9407R User Manual

To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum
space of 6 inches (15 cm) between a wall and the chassis and power supply unit air intakes or a wall and the
chassis and power supply unit hot air exhausts. In situations where the switch chassis are installed in adjacent
racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and
the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis may cause the
switch chassis that is drawing in the hot exhaust air to overheat and fail.
