• PROPER AIR VENTILATION IS REQUIRED.
o Air temperature inside the rack enclosure should NEVER exceed 50°C (122°F).
o Since the Switch itself is relatively passive, no additional clearance is needed
between it and the nearest modem.
o The CRS-300 CANNOT have rack slides mounted to the sides of the chassis –
air flow must not be impeded. Comtech EF Data recommends that an
alternate method of support is provided within the rack, such as standard rack
shelves, as needed.
o Make sure there is adequate clearance inside the enclosure, especially at the
sides, for air ventilation. In a rack system where there is high heat discharge,
provide forced-air cooling with top- or bottom-mounted fans or blowers.
