NE40E Upgrade

Huawei Quidway Huawei NE40E  is based on a 400G platform, which is designed to save energy. Each slot has a forwarding capacity of 400Gbps, and the bandwidth of each slot can be smoothly expanded from 40Gbps to 400Gbps, satisfying the bandwidth demands of the next three to five years.

Pre-upgrade         Ensure that the log function is enabled to record operation data for the upgrade.

   Save the configuration file of the source version, so that if the upgrade fails, you can roll back the NE40E-X1&NE40E-X2 to the source version using the saved configuration file.

   Setting a small traffic rate is recommended. This helps prevent possible NE40E-X1&NE40E-X2 upgrade failures. The traffic rate can be changed to an appropriate value after the upgrade.

Upgrade in process    Do not install, power off, restart, or remove any boards.

   Load correct paf.txt and license.txt files.

   Use commands with the slave parameter only when double MPUs are installed on an NE40E-X1&NE40E-X2.

   Skip the step of upgrading an SFU when upgrading an NE40E-X1&NE40E-X2as there is no SFU.

   Stop upgrading an LPU manually if its CPU usage exceeds 90%. High CPU usage slows down the upgrade process or results in an upgrade failure. Proceed with the upgrade after CPU usage falls below 80%.

Post-upgrade    Ensure that the following conditions are met:

   Boards register with the MPU successfully.

   Board components support the target version.

   No configuration data is missing.
