T640 Clearance Requirements for Airflow and Hardware Maintenance

 

When planning the installation site, you need to allow sufficient clearance around the rack (see Figure 1):

  • For the cooling system to function properly, the airflow around the chassis must be unrestricted. Airflow Through the Chassis depicts the airflow in the router.

    Note

    If you mount the router in a cabinet, be sure that ventilation is sufficient to prevent overheating.

  • For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. At least 24 in. (61 cm) is required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the rack.
