Powering On the NIP6830 - DC Power Distribution

Powering On the NIP6830 - DC Power Distribution

Check whether the NIP6830 is operating properly with the DC power supply. Power on the NIP6830 according to the following requirements to ensure device security.


Before performing a power-on check, switch all circuit breakers to the OFF position.

Before you power on the , ensure that:

  • The power cable and PGND cable are properly connected.
  • The power switch in the equipment room is easy to locate so that you can quickly power off devices in case of any problems.


  1. Turn on the circuit breakers of external DC power supplies A and B.
  2. Measure the input voltage of the device with a multimeter to ensure that the voltage falls between -72 V DC and -38 V DC.
  3. Turn on the DC power switch of the device.
  4. Wait three minutes and then check the status of the indicators.

    Figure 2-23 shows the indicator status of main parts when the device is operating properly. Table 2-4 describes all indicators.

Status Description

DC power module



If this indicator is steady on, the power module is working properly.



Alarm indicator. If the indicator is steady red:

  • The lightning protection circuit of the power module is faulty.

  • There is no power input.




If the indicator blinks once every two seconds (0.5 Hz), the FAN is working properly.


If the indicator blinks once every two seconds (0.5 Hz), the fan module or power module is faulty, or the power module does not have input power.




From the time the MPU is powered on until it is registered, the indicator status changes from off, blink once every 250 ms (4 Hz), off, steady on, and then to blink once every two seconds (0.5 Hz).

After the MPU is registered, the MPU is working properly if the indicator blinks at 0.5 Hz.


Possible causes for an off indicator include:

  • The BootROM is damaged.

  • The MPU cannot be powered on.

Possible causes for the indicator blinking quickly include:

  • The CF card is faulty.

  • The other control chips on the MPU are faulty, preventing the MPU from initializing.



If the indicator is steady off, the MPU is in the normal state. If the indicator is steady red, an alarm is generated.
