Clearance Requirements for Airflow
and Hardware Maintenance
When planning the installation site, you need to allow sufficient clearance
around the rack (see Figure 17):
- For the cooling system to function properly, the airflow around
the chassis must be unrestricted. Allowing at least 6 in. (15.2 cm)
of clearance between each side of the chassis and adjacent racks or equipment
is recommended, particularly for routers in which air flows from side to side
through the chassis. Figure 10 depicts the airflow
in the M5 and M10 routers.
- For service personnel to remove and install hardware components,
there must be adequate space at the front and back of the router. Allow at
least 24 in. (61 cm) in front of the router and 19 in. (48.3 cm) behind it.
