Ptx5000 Clearance Requirements For Airflow And Hardware Maintenance - Juniper PTX5000 Hardware Manual

PTX5000 Clearance Requirements for Airflow and Hardware
Maintenance
When planning the installation site, allow sufficient clearance around the rack (see
168):
• 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 PTX5000. 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 following components:
• Front cable management system—3.8 in. (9.7 cm) additional depth in the front of the chassis.
• Front door—5.5 in. (14 cm) additional depth in the front of the chassis.
• Rear cable management system—5.5 in. (14 cm) additional depth in the rear of the chassis.
