Temperature and Physical Specifications
For temperature and physical specifications, refer to the Physical characteristics table in the Cisco 8000 Series
Routers Data Sheet.
Weight and Power Consumption
For weight and power consumption, refer to the Physical characteristics table in the Cisco 8000 Series Routers
Data Sheet.
Airflow Direction
The airflow through the fan trays and power supplies on the Cisco 8800 series routers routers are from front
to back (port side intake).
To ensure proper airflow for the router in your facility, position the router with its air intake on a cold aisle
and the air exhaust on a hot aisle.
