and t hat all local fire, safety, and electrical codes and ordinances be observed

when you are in

stalling and operating your equipment.

F ire Suppression

In the event of an electrical hazard or an electrical fire, first unplug

the power cord

. (For s hu tdown instructions, see “Powering a S ervices

Router On and Off” on pa ge 90.)

Then, use a Type C fire extinguisher, which uses noncorrosive fire retardants,

to extinguish the fire. For more information about fire extinguishers,

see “Fire Sup

pression Equipment” on page 74.

F ire Suppression Equipment

Type C fire extinguishe rs, which use noncorrosive fire retardants su c h as carbon

dioxide (CO

) and Halo tron, are most effective for suppressing electrical fires.

Type C fire extinguishers d isp lace the oxygen from the point of combustion to

eliminate the fire. For extinguishing fire on o r around equipment that draws air

from the env

ironment for cooling, use this type of in ert oxygen displace ment

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. I n addition, in minute amounts of moisture, m on oa mmonium

phosphate can become highly corrosive and corrodes most metals.

NOTE: To ke

ep warranties effective, do not use a dry chemical fire extinguisher to

control a fire at or near a Juniper Networks router. If a dry chemica l fire extinguisher

is used, the unit is n o longer eligib le for covera ge u nde r a service agreement.

Any equipment in a room in which a chemical fire extinguisher has been

discharged is sub ject to premature failure and unreliable operation. The

equipment

is considered to be irreparably dama ged.

We recomme

nd that you dispose of any irreparably damaged equipment

in an environmentally responsible manner.
