QSW-98ХХ Series Switch Hardware Installation and Reference Guide 20
www.qtech.ru
The QSW-9810 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-9810 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. The supervisor and service modules use fans to draw air and the switch fabric module uses fans to blow
air for forced convection in order to ensure that the device works properly in the specified environment.
