Follow these guidelines:
For the cooling system to function properly, the airflow around the chassis must be unrestricted. See
"PTX10008 Cooling System and Airflow" on page 46
about the airflow through the chassis.
If you are mounting a PTX10000 in a rack with other equipment, ensure that the exhaust from other
equipment does not blow into the intake vents of the chassis.
Leave at least 24 in. (61 cm) both in front of and behind the PTX10000 for service personnel to remove
and install hardware components. To be NEBS GR-63 compliant, allow at least 30 in. (76.2 cm) in front
of the rack and 24 in. (61 cm) behind the rack.
