Power-on Check

Power-on Check

Power-on Check Flowchart

  • Before performing a power-on check, ensure that the device power switch is OFF. Ensure that the input voltage is normal before powering on the device.
  • The normal DC power distribution voltage ranges from -40 V DC to -72 V DC. The normal AC power distribution voltage ranges from 100 V AC to 240 V AC.

Indicators on the NE40E-X16A

Module/Board

Indicator

Color

Description

Power monitoring module (PMU)

RUN

Green

  • Blinking quickly (2 Hz) indicates that the board has not registered.
  • Blinking slowly (0.5 Hz) indicates that the board has registered and communicates normally with other boards.

ALM

Red

ON indicates that an alarm is generated and OFF indicates that no alarm is generated.

ACT

Green

ON indicates that the PMU is the master one and OFF indicates that the PMU is the backup one.

Power module (PM)

Input

Green

  • Blinking slowly (0.5 Hz) indicates overvoltage or undervoltage of input power.
  • ON indicates correct input voltage.

Output

Green

ON indicates correct output voltage and OFF indicates incorrect output voltage.

Alarm

Red

ON indicates that an alarm is generated and OFF indicates that no alarm is generated.

Fan assembly (FAN)

STATUS

Green

Blinking slowly (0.5 Hz) indicates that fans work normally, and blinking quickly (2 Hz) indicates that fans work abnormally.

Red

Blinking slowly (0.5 Hz) indicates that communication is normal but an alarm is generated. The alarm indicates an error in fans, one channel of power, or sensors.

MPU

RUN

Green

Before the MPU is powered on and registers, the indicator status changes in the following sequence: off -> blinking quickly (2 Hz) -> off -> steady on -> blinking slowly (0.5 Hz).

After the MPU is powered on and registers, the indicator blinks at 0.5 Hz, indicating that the board is working properly.

NOTE:

Possible causes for the indicator to stay off are as follows:

  • The BootROM is damaged.
  • The MPU cannot be powered on.

Possible causes for the indicator to blink quickly are as follows:

  • The SSD card is faulty.
  • The other control chips on the MPU are faulty, causing an initialization failure on the MPU.

ALM

Red

If the indicator is steady off, the MPU works normally. If the indicator is steady red, an alarm is generated.

SFU

RUN

Green

After the board is powered on but before it registers, the indicator status changes in the following sequence: off -> blinking once every 500 ms (2 Hz) -> off -> steady on -> blinking once every two seconds (0.5 Hz).

After the board registers, the indicator blinks at 0.5 Hz, indicating that the board is working properly.

NOTE:

Possible causes for the indicator to stay off are as follows:

  • The BootROM is damaged.
  • The SFU cannot be powered on.

Possible causes for the indicator to blink quickly are as follows:

  • The flash memory is faulty.
  • The network port is faulty.

ACT

Green

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

LPU

RUN

Green

After the board is powered on but before it registers, the indicator status changes in the following sequence: off -> blinking once every 500 ms (2 Hz) -> off -> steady on -> blinking once every two seconds (0.5 Hz).

After the board registers, the indicator blinks at 0.5 Hz, indicating that the board is working properly.

NOTE:

Possible causes for the indicator to stay off are as follows:

  • The BootROM is damaged.
  • The LPU cannot be powered on.

Possible causes for the indicator to blink quickly are as follows:

  • The flash memory is faulty.
  • The network port is faulty.

Link/ACT

Green

  • If this indicator is off, the link is Down.
  • If this indicator is steady on, the link is Up.
  • If this indicator is blinking, data is being transmitted.
