Replacing CF Card 2

Replacing CF Card 2

This section describes the procedure for replacing CF card 2.


Before replacing CF card 2, note the following:

  • CF card 2 of a NIP device supports hot swap. Therefore, before replacing CF card 2 of a NIP device, press the CF OFL button on the panel of the MPU/SRU.

  • CF card 2 lies on the panel of the MPU/SRU, so you do not need to pull out the MPU/SRU before replacing CF card 2.

  • When CF card 2 is replaced, the device log and alarm information cannot be stored.


Before replacing CF card 2, you need the following tools:

  • ESD wrist strap or ESD gloves

  • ESD bag


  1. Check the location of the CF card to be replaced.

    Before pulling out the CF card that is to be replaced, check the location of the CF card, that is, the cabinet and chassis where the CF card resides. Then locate the MPU/SRU whose CF card is to be replaced and label the MPU/SRU.

  2. Press the CF OFL button on the panel of the MPU/SRU for about 6 seconds until the CF ACT indicator turns off.
  3. Open the shielding can on the CF card, as shown in Figure 3-34 (1). Press the button on the CF card 2 jack, as shown in Figure 3-34 (2). The CF card automatically pops out. Remove the CF card, as shown in Figure 3-34 (3).

  4. Place the removed CF card in the ESD bag.
  5. Insert the new CF card into the CF card 2 slot the MPU/SRU and push it in the proper position, as shown in Figure 3-35 (1). Close the shielding can properly, as shown in Figure 3-35 (2).

  6. Check whether the new CF card is working properly.

    You can check the running status of the new CF card in the following ways:

    • Check the CF ACT indicator (green) on the panel of the MPU/SRU. If it is steady on or blinking, the new CF card is working normally.

    • Check the alarms. If the system does not generate any alarm related to the new MPU/SRU, the CF card is working properly.

    • Run the dir command on the console interface to check whether the new CF card can be displayed. If the new CF card is working normally, the following is displayed:

    <sysname> dir ?
      /all            List all files
      STRING<1-64>    [drive][path][file name]
      cfcard2:         Device name
      cfcard:          Device name
      slave#cfcard2:  Device name
      slave#cfcard:   Device name

    The preceding output also indicates that the new CF card has returned to the normal state. If the new CF card does not work normally, contact a local Huawei office for technical support.

Follow-up Procedure

After replacing the CF card, collect all tools. If the replaced CF card 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.
