Checking Whether Each Pair Has Dual Controllers

A replacement component is ready.
The controller that you want to replace has been located.
NOTE:
You can locate components in either of the following ways:
- On the device view of the management software, view and record the location of the component that you want to replace. For components that have location indicators, turn on the location indicators (for details, see the online help of the management software).
- Locate the faulty component based on the alarm indicator.
The cable connection positions of the controller that you want to replace are labeled on the cables.

Remove and insert an interface module with even force. Excessive force may damage the appearance or connectors of the interface module.
Remove one controller each time to avoid service interruption.
If two controllers are faulty, contact Huawei technical support engineers.
You are advised to replace a controller module within the shortest time possible.
After a user manually replaces the public/private key pair of ibc_os_hs, the public/private key pairs of all other functional controllers must be initialized before controller replacement.
To initialize the public/private key pairs, log in to the serial port of the controller enclosure as user _super_admin (the default password is Admin@revive) and run the initibckey command.
