Cooling
Table 11. Cooling specifications
Parameter Specification
Thermal dissipation See the Power consumption information in the Product specifications section
Number of fixed fans 1 (1425) or 2 (1445 and 1485)
Minimum CFM 5.6 (one fan)
Maximum CFM 10 (two fans)
NOTE: For thermal considerations, do not stack the VEP1405 platforms on top of each other. Stacking of the platforms
impairs cooling and places the external power supply on top of the unit.
