MA5608T Fan Tray
A fan tray functions heat dissipation, monitoring, and fan speed adjustment, which ensures that the device works at a stable temperature.
Two fans are configured in the fan tray of the MA5608T.
|Dimensions (W x D x H)
|Power consumption (including FCBB board)
- Static: 4 W
- Maximum: 39 W
The functions of the fan tray are as follows:
- Heat dissipationThe 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.
- MonitoringThe 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 adjustmentThe rotating speed of the fans can be adjusted according to the detected temperature automatically or be adjusted by software manually.
The ESD jack of the MA5608T chassis is on the middle of the fan tray, which is used to connect the ESD wrist strap to prevent device damage caused by electrostatic discharge.

Ground the chassis shell securely so that the influence electricity, leakage electricity can flow to the ground, improving the protection against electromagnetic interference.
Use a ground cable to connect the ground point of the chassis shell to the ground bar of the telecommunications room or to the ground directly. It is recommended that the grounding resistance of the telecommunications room should be less than 10 ohms. Refer to the local standards to ground the chassis.
The ground point of the chassis shell is on the left of the chassis, and there is a ground point on the front of the left mounting bracket as shown

Power Distribution Principle
The MA5608T chassis adopts AC and DC power supply. This topic describes the power distribution principle of the MA5608T chassis.
The MPWC power interface board leads two -48 V input to the backplane, and then the backplane supplies power to each board.
The MPWC boards supports two -48 V DC input. If one input is off, the other supplies power to the chassis can guarantee normal running of the system.
The MPWD power interface board supports the AC input. After AC/DC conversion, the power is supplied to the system backplane at -48 V DC.
Two MPWE boards can be configured for dual-system hot backup. Each MPWC board supports one -48 V DC input. If one MPWE board is off, the other supplies power to the chassis can guarantee normal running of the system.
This topic describes the ventilation of the MA5608T chassis.
The MA5608T chassis has a fan tray at the left to blow air for heat dissipation.
The airflow for the MA5608T chassis is as follows: The cool air flows to the chassis through the left side, and then the fans blow the air to the right side of the chassis through the boards. Finally, the air exits through the right side of the chassis
