Weight and Power Consumption
For weight and power consumption, refer to the Physical characteristics table in the Cisco 8100 Series Routers
Data Sheet.
Airflow Direction
The airflow through the fan trays and power supplies on the Cisco 8500 switches are from front to back (port
side intake).
To ensure proper airflow for the switch in your facility, position the switch with its air intake on a cold aisle
and the air exhaust on a hot aisle.
