Page 87: Appendix E: Environmental Guidelines
This is not necessarily the same air temperature throughout the room. Cooling Air Many Enterasys switches utilize a side to side airflow method for cooling. Careful consideration is needed when mounting this equipment. Proper inlet and exit spaces must be allowed to get fresh, cool air into the equipment and to allow hot exhaust air to exit away from the equipment. -
Page 88: Airflow Concerns For Closed Racks
Temperature and Humidity Guidelines Airflow Concerns for Closed Racks When placing Enterasys switches into enclosed racks, rack exhaust fans must be considered if the rack does not contain adequate inlet and exit venting. These fans may be needed to help exhaust hot air from the rack. -

Page 90: Non-Ideal Open Rack Configuration
Temperature and Humidity Guidelines Figure E-3 Non-ideal Open Rack Configuration Non-ideal flows should be avoided or mitigated and confirmed through thermal testing. Figure E-4 below shows a non-ideal open rack configuration containing sub-systems with mixed flow directions (white arrows). This configuration shows mitigation of potential hot air recirculation by leaving a gap in the rack population. -
Page 91: Dust Mitigation And Prevention
Dust accumulation on inlet and exit venting is not uncommon after prolonged use. In dustier environments this accumulation can be much quicker. Enterasys strongly recommends routine maintenance to check for clean inlet and exit vents on this equipment. Over time, dust accumulation can create vent blockages, thereby decreasing airflow and increasing component temperatures, resulting in reduced reliability. -
