When mounting this equipment in the rack, do not obstruct the cooling airflow through the
rack. Be sure to mount the blanking plates to cover unused rack space. Additional
components such as combiners and net strips should be mounted at the back of the rack, so
that the free airflow is not restricted.

meets the requirements given in this equipment's technical specifications.
CAUTION:
If installed in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient temperature. Therefore,
install this equipment in an environment compatible with the manufacturer's
maximum rated ambient temperature.
