The mechanical and electrical environmental conditions at the installation site must be within the limits described in the technical manual.
Avoid installation in dusty, damp places.
Avoid places susceptible to rapid temperature variations, powerful vibrations and shocks, surge voltages of high amplitude and fast rise time, strong induced magnetic fields or similar extreme conditions.
Check that sufficient space is available.
Sufficient space is needed at the front and rear of the device to allow access to Ethernet cables and optical fibers to provide sufficient ventilation to the device and to enable maintenance and future modifications.
