Reduced Airflow 
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. 
  CAUTION: 
Installation of this equipment in a rack should be such that the amount of 
airflow required for safe operation of this equipment is not compromised.

Only install this equipment in a humidity- and temperature-controlled environment 
that 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.
