Checking Controller Faults

The replacement components are ready.
The controller that you want to replace has been located.
NOTE:
You can locate the components in either of the following ways:
- Check and record the location of the replacement components in the Device View of the management software. You are advised to light the location indicators of the components (for details, see the online help of the management software).
- Locate the faulty components based on the location indicators.
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.
When two controllers are faulty, contact Huawei technical support engineers.
You are advised to replace a controller module within the shortest time possible.
The password of the ibc_os_hs account of each controller and data switch in the system must be the default one. The S2600T does not involve any data switch.
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 initibckey.
