Fire Safety Requirements
This topic applies to hardware devices in the EX Series product family, which includes
EX Series switches, the EX Series Redundant Power System (RPS), and the XRE200
External Routing Engine.
This topic also applies to hardware devices in the QFX Series and to OCX1100 switches.
In the event of a fire emergency involving switches and other network equipment, the
safety of people is the primary concern. You should establish procedures for protecting
people in the event of a fire emergency, provide safety training, and properly provision
fire-control equipment and fire extinguishers.
In addition, you should establish procedures to protect your equipment in the event of a
fire emergency. Juniper Networks products should be installed in an environment suitable
for electronic equipment. We recommend that fire suppression equipment be available
in the event of a fire in the vicinity of the equipment and that all local fire, safety, and
electrical codes and ordinancesbe observed when you install and operate your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, you should first turn power off to
the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive
fire retardants, to extinguish the fire.
