(4) Switch (models AX1240S-24P2C and AX1240S-48T2C)
The airflow into and out of the Switch is shown in Figure 2-9 Airflow for models
AX1240S-24P2C and AX1240S-48T2C.

2.9.2 Cooling conditions for the Switch on a table
Ensure more than 50 mm of space for air flow from the sides of the device.
Do not block the ventilation slots. Otherwise, internal heat is not discharged, which
may cause damage. Maintain a space of at least 50 mm around the ventilation slots.
When other equipment with a forced air cooling system exists near this switch, air
flow from different systems can interfere and adversely affect the cooling of the
switch. Keep sufficient space or place a partition between the systems to prevent air
flow interference.
Note that the partition should be more than 50 mm away from the side panel of the
switch.
 The exhausted air from other equipment might be taken into the switch, and
the intake air temperature of the switch might exceed the environmental
specification limits.
 When other equipment has an intake or exhaust air system that is too strong,
air moving in the opposite direction of the switch's air flow might be generated,
affecting the internal cooling performance.
2.9.3 Cooling conditions for a rack-mounted device
Ensure more than 50 mm of space between the device and all structural components of the
