Powering On the NIP6860 - DC Power Distribution

Powering On the NIP6860 - DC Power Distribution

Check whether the NIP6860 is operating properly with the DC power supply. Power on the NIP6860 according to the following requirements to ensure device security.

Context

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.

Procedure

  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. 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 2-41 shows the indicator status of main parts when the device is operating properly. Table 2-6 describes all indicators.

    NOTE:

    If not all power modules have four inputs, the STATUS indicator of the fan module is steady red.

Item

Indicator

Color

Status Description

PEM

RUN

Green

If the indicator is steady green, the PEM has normal output.

ALM

Red

Alarm indicator. If the indicator is steady red:

  • The lightning protection circuit of the PEM is faulty.

  • There is no power input.

FAN

STATUS

Green

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

Red

If the indicator blinks once every two seconds (0.5 Hz), the fan module or PEM is faulty, or not all PEMs are powered on.

MPU/SRU

RUN

Green

From the time the MPU/SRU 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/SRU is registered, the MPU/SRU is working properly if the indicator blinks at 0.5 Hz.

NOTE:

Possible causes for an offline indicator are:

  • 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/SRU are faulty, preventing the MPU/SRU from initializing.

ALM

Red

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

SFU

RUN

Green

From the time the SFU 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 SFU is registered, the SFU is working properly if the indicator blinks at 0.5 Hz.

ACT

Green

If the indicator is steady green, the SFU is working properly; if the indicator is off, the SFU is faulty.
