MA5603T Fan Tray(FMCA)
A fan tray functions heat dissipation, monitoring, and fan speed adjustment, which ensures that the device works at a stable temperature.
Appearance
Six fans are configured in the fan tray (FMCA) of the MA5603T.
Specification
Item | Specification |
Dimensions (W x D x H) | 53.0 mm x 272.5 mm x 245.7 mm |

Function
The functions of the fan tray are as follows:
Heat dissipation
The fan tray is at the left of the service subrack and blows air for heat dissipation of the service subrack. The cool air flows to the subrack from the left of the subrack and then is exhausted from the right of the subrack after passing the boards.
Monitoring
The fan tray is configured with a fan monitoring board. The fan monitoring board transmits speed adjustment signals to the fan tray, collects the rotating speed signals of the fans, and reports the rotating speed signals to the control board.
Speed adjustment
The rotating speed of the fans can be adjusted according to the detected temperature automatically or be adjusted by software manually.
LED
Indicator | Status | Meaning | Operation Description |
STATUS | Yellow: blinks every 0.3s | The fan tray is not registered or is being loaded. | No action is required. |
The communication between the host and the fan tray is interrupted. | Check communication between the fan tray and device. | ||
Green: blinks | The fan tray works in the normal state. | No action is required. | |
Yellow: blinks every 1s | The fan tray generates alarms that do not affect services. | Handle it based on the corresponding alarm. | |
Red: blinks | The fan tray is faulty or the fan tray generates an over-temperature alarm. | Increase the fan speed to lower the temperature. Replace the faulty fan tray. |
DIP Switches
The fan tray uses the FMCA monitoring board, which supports the -48 V / -60 V input voltage, which provides a set of DIP switches S1.
NOTE:
When S1-1, S1-2, and W1-3 are used to set the subnode address, make sure that the DIP switch settings are consistent with the data configuration. But the subnode address value cannot be the same as that of the environment monitoring board.
NOTE:
The fan tray (FMCA) of the MA5603T must use speed adjustment policy 1.
Fan Speed Adjustment
Set the fan speed adjustment mode to "automatic" or "manual" in the command line interface (CLI). After the fans are installed, they work in automatic mode by default.
Automatic mode
Control-system-triggering: The control system automatically adjusts fan speed according to the board temperatures for energy conservation.
Monitoring-board-triggering: The speed is automatically adjusted based on the temperature which is detected by a temperature sensor.
NOTE:
The automatic mode has two variants (automatically selected by the system): control-system-triggering and monitoring-board-triggering.
Manual mode
Commands are executed to adjust fan speed. The levels range from 0 to 6, level 0 being the lowest speed and level 6 being the highest speed.
