Cooling Conditions For The Switch On A Table; Cooling Conditions For A Rack-Mounted Device - Alaxala AX3800S Hardware Instruction Manual

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 air vents of the device. Otherwise, the internal heat is not
discharged, which may cause a fire. Keep more than 50 mm of space from the air
vents.
When other equipment with a forced air cooling system exists near this switch, air
NOTE
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.

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 rack including the side walls, pillars, guide rails and front and rear doors.
Do not block the air vents of the device. Otherwise, the internal heat is not
discharged, which may cause a fire. Keep more than 50 mm of space from the air
vents.
Make sure that the temperature inside the rack is within the operating temperature
NOTE
specified for the switch. Otherwise, the device might malfunction or fail. To meet the
temperature requirements, consider the following means:



When other equipment with forced air cooling system exists above or under this
NOTE
device, air flow from different systems can interfere and adversely affect cooling,
causing a malfunction or a failure. Keep spaces between the systems in the rack to
prevent air flow interference.


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.
Install fans inside the rack for sufficient ventilation.
Replace the front and the rear doors with punched holes for cooling or remove
the doors in order to achieve good ventilation.
Reduce the number of items contained in the rack and mount the device
under other heat emitting bodies when necessary.
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.
