The QSW-9807 switches support N+M system power redundancy and 1+1 PoE power redundancy to improve the

system stability and reliability. We recommend users to configure redundancy for power supply modules.

Heat Dissipation Solution

The operating environment temperature of QSW-9807 switches ranges between 0 and 50°C. The heat dissipation design

must satisfy the requirement on the device's reliability in the temperature range while ensuring the device's safety and

maintainability. According to the thermal design of the QSW-9807 switch, fans are used to draw air for forced convection

cooling in order to ensure that the device works properly in the specified environment.
