Feature and Specifications
Seamless backup for TS input.
MPTS/SPTS multiplexing
DVB service
1:8 TS output
Temperature reading and high-temperature alarm
Automatic power-off in case of high temperature
Parameters
Board Parameter
You can query power consumption, weight, maximum frame size, and normal operating temperature of all boards.
Table 1 lists the power consumption, weight, and maximum frame size of boards.
The operating temperature of H901XSED and H901TWED is -40°C to +55°C (in MA5800–X17/X15/X7) or -40°C to +65°C (in MA5800–X2) and the lowest board startup temperature is -25°C. The operating temperature of other boards is -40°C to +65°C and the lowest board startup temperature is -25°C.
NOTE:
The power consumption of a board is calculated based on the following conditions:
Operating voltage: -53.5 V DC.
Ambient temperature: 25°C.
Static power consumption: All ports do not carry any loads and optical modules are not installed on optical ports.
Maximum power consumption: All ports fully carry loads.
The board power consumption slightly varies with the power module configured for the board and discreteness of components.

Indicates the channel of control signal. | Indicates the channel of service signal. | ||
Control module: loads the board software, controls the running of the board, and manages the board. | Service processing module: backs up and multiplexes the DVB services sent from the backplane; forwards them back to the control board through the backplane. | ||
Indicates the channel of power or clock signal. | The power module supplies power to each functional module of the board. The clock module provides clock signals for each functional module of the board. |
Front Panel Port
The H901CVEC board does not provide external ports.
Indicator
Indicator | Name | Status | Operation Description |
RUN/ALM | Running status indicator | Red: blinks | The board enters the APP start phase during the board startup |
Green: blinks every 0.25s | The board enters the phase of communication with the control board during its startup | ||
Green: blinks every 1s | The board works in the normal state | ||
Orange: blinks every 0.25s | A high-temperature alarm is generated | ||
Red: on | The board is faulty |
