4.2 Replacing a Controller
The RAID controller monitors and manages the logical drives. When the controller is replaced, all the logical drive data
remains intact because the logical drive information is stored on the disk drives.
When a controller fails, you can replace the controller with a new one. The controllers are hot-swappable, which means
they can be replaced even when the RAID system is powered on and functioning.
To replace a faulty controller, follow the procedures below:
1. Disconnect the host cables, mananagement, and serial power cables connected to the faulty controller.
2. Loosen the screws of the controller.
3. Lift the handle to eject the controller.
4. Gently pull out the controller.
5. Insert the new controller into the slot with the handle lifted.
6. Push down the handle to lock the controller into place.
7. Tighten the screws to secure the controller.
8. Connect the host cables, management and serial cables.
Note
Before replacing the controller, be sure the replacement controller is greater or has the same
memory capacity as the original controller.
