Internal and external NetServer covers provide proper cooling airflow. To ensure
data integrity, all covers must be in place, regardless of the external environment
(stand-alone or rack-mounted) or temperature (e.g. air conditioned). Even at low
room temperatures, ensuring that all covers and panels are in place provides
controlled airflow and system reliability. This does not include the front doors, which
may be removed without risk.
