Cabinet-sharing Installation
The RTN 980 can be placed in a stacked manner.
When the RTN 980 and other type of equipment are installed in the same cabinet, it is recommended that
you reserve a 2U or greater space for heat dissipation.
When the RTN 980 and other type of equipment are installed in the same cabinet, the temperature in the
air outlet needs to be lower than 50°C if the lower equipment emits the air on its top. Otherwise, use an
air guide plate for separation between the upper equipment and the lower equipment.
