Qualified Personnel Warning for J-EX Series Switches

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.
Fire Suppression Equipment
Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide
and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers
displace 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 leaves
residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers). The primary ingredient in these fire extinguishers is monoammonium
phosphate, which is very sticky and difficult to clean. In addition, in the presence of 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.
NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher
to control a fire at or near a switch running Junos OS. If a dry chemical fire
extinguisher is used, the unit is no longer eligible for coverage under a service
agreement.
We recommend that you dispose of any irreparably damaged equipment in an
environmentally responsible manner.
