NOTICE
NOTICE
When installing the device in a closed or multi-device rack, be aware the
operating ambient temperature of the rack may be higher than the ambient
temperature of the room. Make sure the rack is installed in a suitable
environment that can withstand the maximum ambient temperature generated
by the rack.
Make sure each device in the rack is separated by at least one rack-unit of
space, or 44 mm (1.75 in), to promote convectional airflow. For CSA compliant
installations, a minimum forced airflow of 0.27 m/s at 400 CFM is required.
Note that any increase in airflow will result in a reduction of ambient
temperature and improve the long-term reliability of all equipment mounted in
the rack space.
Do not exceed the maximum number of devices or weight restrictions specified
by the rack manufacturer.
Do not overload the supply circuit. Refer to the over-current protection and
power supply ratings specified by the rack manufacturer.
Make sure the rack and all devices have a proper ground-to-Earth connection.
Pay particular attention to power supply connections other than direct
connections to the branch circuit (e.g. power strips).
