Replacing CF Card 1

Replacing CF Card 1

This section describes the procedure for replacing CF card 1.


Before replacing CF card 1, note the following:

  • CF card 1 lies on the circuit board of the MPU/SRU. Pull out the MPU/SRU before replacing CF card 1.

  • The contents on the new CF card must be consistent with the contents on CF card 1.


Before replacing CF card 1, 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. Check whether the MPU/SRU whose CF card is to be replaced is the active MPU/SRU.

    Look at the ACT indicator on the MPU/SRU to check whether the MPU/SRU is the active. The MPU/SRU whose ACT indicator is the active. The MPU/SRU who ACT indicator is off is the standby.

  3. If the MPU/SRU whose the CF card is to be replaced is the active, run the following commands to perform the active/standby switchover:

    <sysname> system-view
    [sysname] slave switchover enable
    [sysname] slave switchover

  4. Power off the MPU/SRU whose CF card needs is to be replaced.

    Press and hold the OFL button on the panel of the MPU/SRU for six seconds until the OFL indicator turns on. This means that the MPU/SRU is powered off.

  5. Pull out the MPU/SRU whose CF card is to be replaced and place the MPU/SRU horizontally on the worktable, as shown in Figure 3-32 (1). For more details, see "Replacing an MPU/SRU."
  6. Press the button on the jack of CF card 1, as shown in Figure 3-32 (2). The CF card automatically pops out. Remove the CF card vertically, as shown in Figure 3-32 (3).

  7. Place the removed CF card in the ESD bag.
  8. Insert the new CF card into the CF card 1 slot on the MPU/SRU and push the CF card into the proper position, as shown in Figure 3-33 (1).
  9. Insert the MPU/SRU into the chassis, as shown in Figure 3-33 (2). For more details, see Replacing an MPU/SRU.

  10. Check whether the new CF card is working normally.

    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.

    • 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.
