Clearance Requirements for Airflow and Hardware Maintenance for QFX5120 Switches

 

When planning the site for installing a QFX5120 switch, you must ensure sufficient clearance around the switch.

  • See Figure 1 for clearance requirements for QFX5120-32C switches.

  • See Figure 2 for clearance requirements for QFX5120-48T switches.

  • See Figure 3 for clearance requirements for QFX5120-48Y switches.

  • See Figure 4 for clearance requirements for QFX5120-48YM switches.

Follow these clearance requirements:

  • For the cooling system to function properly, ensure that the airflow around the chassis is unrestricted.

  • If you are mounting the switch on a rack or cabinet along with other equipment, ensure that the hot air exhaust from other equipment does not blow into the cold air intake vents of the chassis.

  • Leave at least 6 in. (15.2 cm) clearance in front of and behind the chassis for airflow.

  • Leave at least 6 in. (15.2 cm) clearance on the left of the chassis for installing the grounding lug.

  • NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.

  • Leave at least 24 in. (61 cm) clearance in front of and behind the switch for service personnel to remove and install hardware components.
