When planning the installation site, allow sufficient clearance around the rack (see
30 on page 59):
For the cooling system to function properly, the airflow around the chassis must be
unrestricted.
NOTE: If you mount the chassis 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 chassis. At least 24 in. (61.0 cm) are
required both in front of and behind the packet transport switch. NEBS GR-63
recommends that you allow at least 30 in. (72.6 cm) behind the rack.
Additional clearance is required to accommodate the depth of the cable management
system: 3.8 in. (9.7 cm) additional depth in the front of the chassis.
