In the case of Access device, power consumption is generally transformed into heat consumption.
Hence, heat consumption (BTU/h) and power consumption (W) can be converted to each other in the
formula: 1 BTU/h = 0.2931 W.
Heat dissipation
The fan tray is at the top of the service subrack and exhausts hot air for heat dissipation.
The cool air flows to the subrack from the bottom of the subrack and then is exhausted
from the top of the subrack after passing the boards.
Monitoring
The fan tray is configured with the fan monitoring board to detect whether the fans are
working in the normal state. The fan monitoring board also provides the port for
communication with the control board. The detected information is transmitted to the
control board through the fan monitoring board periodically.
Speed adjustment
The rotating speed of the fans can be adjusted according to the detected temperature
automatically or be adjusted by setting the related data manually.
