Replacing an AC Power Module of the NIP6830

Replacing an AC Power Module of the NIP6830

This section describes the procedure for replacing an AC power module of the NIP6830.

Context

  • Before replacing a power module, switch off the corresponding circuit breaker on the power distribution cabinet. This powers off the power module to be replaced. In addition, switch off the power module to be replaced.

  • The NIP6830 has two power modules. Do not power off the other during the process of removing one power module.

  • The NIP6830 has one type of AC power module: 2200 W. Figure 3-23 shows the power modules.
    Figure 3-23  R4850G2 AC power module (2200 W)

    When AC 110 V input is used, the AC power module is half-load output, which cannot support the maximum system power consumption with the full configuration. Therefore, two AC power modules are required for the device to work properly. If one AC power module fails, the other cannot support the maximum system power consumption. That is, 1+1 redundancy fails.

Tool

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

Procedure

  1. Check the location of the power module to be replaced.

    Before pulling out a power module to be replaced, check its location, that is, the cabinet and chassis where the power module resides, and label the power module.

  2. Switch off the corresponding circuit breaker on the power distribution cabinet. This powers off the power module to be replaced. In addition, switch off the power module to be replaced
  3. Put on the ESD wrist strap and connect the grounding terminal to the ESD jack on the rack.
  4. Remove the cables from the power module to be replaced, as shown in Figure 3-24 (1).
  5. Replace the power module as follows:
    • Replace the R4850G2 power module.

      1. Disconnect the buckle in the upper right of the power module and lower the ejector lever on the right. Holding the ejector lever, remove the power module from the slot.

      2. Place the new power module in the slot and disconnect the buckle in the upper right. Lower the ejector lever on the right, push the power module slowly along the guide rails until it is in position. Then push the ejector lever back and fasten the buckle. Finally, connect the power cable to the new power module.

  6. Verify that the new power module is working normally.

    After inserting the power module into the chassis, switch on the circuit breaker on the power distribution cabinet and then switch on the power module. Then, you can verify if the new power module is working properly in the following ways:

    • Check the RUN indicator on the panel of the power module. If it is green, the power module is working normally.

      Check the ALARM indicator on the panel of the power module. If it is yellow, a recoverable fault has occurred on the power module.

      Check the FAULT indicator on the panel of the power module. If it is red, an unrecoverable fault has occurred on the power module.

    • Run the display device command on the console interface to check the running status of the new power module. The power module is working normally if the following is displayed:

    <sysname> display device
    NIP6830's Device status:
    Slot #    Type    Online    Register      Status      Primary
    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    1         SPU     Present   Registered    Normal      NA
    2         SPU     Present   Registered    Normal      NA
    3         LPU     Present   Registered    Normal      NA
    4         MPU     Present   NA            Normal      Master
    5         MPU     Present   Registered    Normal      Slave
    6         CLK     Present   Registered    Normal      Master
    7         CLK     Present   Registered    Normal      Slave
    8         PWR     Present   Registered    Normal      NA
    9         PWR     Present   Registered    Normal      NA
    10        FAN     Present   Registered    Normal      NA
    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

    The preceding output also indicates that the power module has returned to the normal state. If the power module fails is not working normally, contact a local Huawei office for technical support.

Follow-up Procedure

After replacing the power module, collect all tools. If the replaced power module is faulty, fill in the Repair Transmission Sheet and send the faulty module with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
