Site Environmental Requirements
Table 17 specifies the environmental conditions required for normal router operation. In
addition, the site should be as dust-free as possible. Dust can clog the air filter, reducing
cooling system efficiency. Check the air filter under the cable management system and the
covers on all cooling subsystems frequently, cleaning them as necessary. For more
information, see “Maintain and Replace Cooling System Components” on page 153.

Fire Safety Requirements
In the event of a fire emergency involving routers 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.
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 ordinances be observed when installing and operating 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. For more information about fire extinguishers, see “Fire
Suppression Equipment” on page 44.
