Before You Start

Before You Start

This section describes the precautions, preparations, and process for replacing a switch module.

Precautions

  • Before the replacement, apply for service interruption of three hours. If you have special requirements for the service interruption time, contact Huawei technical support engineers.
  • Switch modules of version 5.13 or later do not support remote port mirroring or remote traffic mirroring (ERSPAN or RSPAN). Before the replacement, check whether these functions are needed. If you need these functions, use local mirroring instead.
  • If the stack containing the switch module to be replaced has more than two switch modules, upgrade the stacked switch modules that function properly to the latest version before the replacement. For details, see the E9000 Server V100R001 Upgrade Guide.
  • If the switch module to be replaced is CX210, CX912, CX220, or CX916, check whether the FC switching plane of the switch module to be replaced has a license before the replacement. If the CLI of the FC switching plane can be logged in to, run the licenseshow command to check whether a license exists. If the CLI of the FC switching plane cannot be logged in to, contact Huawei technical support. For details about how to log in to the CLI of the FC switching plane, see "Logging In to the FC Switching Plane" in the CXxxx Switch Module User Guide.
    • If a Full Fabric license, ISL Trunking license, or Bundle-TRK, FV, EF, FF license exists, transfer the license to the spare part. For details, see "Transferring Licenses" in the CXxxx Switch Module User Guide.
    • If a POD license exists and the switch module to be replaced is CX220 or CX916, transfer the license to the spare part. For details, see "Transferring Licenses" in the CXxxx Switch Module User Guide.
    • If a POD license exists and the switch module to be replaced is CX210 or CX912, transfer the license. For details, see Importing and Transferring Licenses (Only for the CX210 and CX912).
    • If the switch module to be replaced is a 24-port CX210 or CX912 and the spare switch module is a CX210 or CX912 with 20+4 ports, you need to apply for a POD license and then import it. For details, see Applying for a License (Only for the CX210 and CX912) and Importing and Transferring Licenses (Only for the CX210 and CX912).
    • If the preceding licenses do not exist, you do not need to perform any operation on the license.
  • You may need to upgrade software during the replacement. Therefore, obtain the latest software of the switch module to be replaced at the Huawei technical support website before the replacement.
  • If the switch module to be replaced is CX710:
    1. Run the following command on the CLI of the 40GE converged switching plane to check the current version of the 40GE converged switching plane:

      <HUAWEI> display version

      Figure 6-24 Displayed information (example)
    2. Confirm the PCB version of the CX710.
      • If PCB Version is VER A, continue to replace the switch module.
      • If PCB Version is VER B, the CPLD software cannot be rolled back to version 0.08 or 0.09.
