Replace the battery only with the same or equivalent type recommended by
•
the manufacturer.
Dispose of used batteries according to the manufacturer’s instructions.
•
Do not damage the battery in any way, a damaged battery may release hazard-
•
ous materials into the environment.
Do not discard a used battery in the garbage or a public landfill.
•
Please comply with the regulations set up by your local hazardous waste man-
•
agement agency to dispose of your used battery properly.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture of the rack environment may be greater than the ambient temperature of the
room. Therefore, consideration should be given to installing the equipment in an
environment compatible with the manufacturer’s maximum rated ambient tempera-
ture (Tmra).
Reduced Airflow
Equipment should be mounted into a rack so that a hazardous condition does not
arise due to uneven mechanical loading.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not
arise due to uneven mechanical loading.
