Appendix A Hot-swapping
You may have to change hard disks in some situations, such as hard disk failure, degraded RAID,
Critical RAID or general maintenance. The NAS server supports HDD hot-swapping. Below are
the instructions of replacing hard disks when using the HDD module.
1. Identify which hard disk fails. The amber LED of the HDD tray will blink to indicate hard disk
failure.
2. Unplug the HDD tray and replace the HDD with a good one.
3. Plug in the HDD tray. Wait until the Green LED is steady on.
Then you are done.
When a RAID volume is degraded and there is no available hot-spare disk for rebuilding, the RAID
volume will stay in the degraded state. In this state, you can hot-unplug the failed hard disk and
plug in a good one in the same HDD tray. The RAID volume will rebuild automatically with the new
hard disk.
