The installation of Cisco® switches inside equipment cabinets in the data center is a growing trend. Critical to supporting this trend is the need to address the right-to-left airflow pattern of Cisco 6500 and 9500 switches. Specific steps must be taken to prevent internal re-circulation and the hot exhaust from one switch raising the intake temperature of an adjacent switch. It is also highly desirable to place this equipment in a hot aisle/cold aisle layout without disrupting the data center’s planned airflow pattern. These and other issues are addressed in this white paper.
