Fire Suppression Equipment
Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide
(CO
(CO
2
)
and Halotron™, are most effective for suppressing electrical fires. Type C fire
extinguishers displace the oxygen from the point of combustion to eliminate the fire. For
extinguishing fire on or around equipment that draws air from the environment for cooling,
you should use this type of inert oxygen displacement extinguisher instead of an
extinguisher that leave residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers) near Juniper Networks equipment. The primary ingredient in these fire
extinguishers is monoammonium phosphate, which is very sticky and difficult to clean. In
addition, in minute amounts of moisture, monoammonium phosphate can become highly
corrosive and corrodes most metals.

Any equipment in a room in which a chemical fire extinguisher has been discharged is
subject to premature failure and unreliable operation. The equipment is considered to be
irreparably damaged.

Power System Requirements and Specifications
The router can use either AC or DC power. In either case, there are two load-sharing power
supplies located at the bottom rear of the chassis (see Figure 2). Each power supply requires
a dedicated power source.

To keep warranties effective, do not use a dry chemical fire
extinguisher to control a fire at or near a Juniper Networks
router. If a dry chemical fire extinguisher is used, the unit
is no longer eligible for coverage under a service
agreement.
