Chapter 4: Maintenance
This chapter describes the procedures in maintening the RAID system components to ensure performance quality and
stability.
4.1 Replacing a Disk
When a hard disk fails, the Disk LED indicator lights red and the audible alert sounds.
Hard disks are hot-swappable, which means they can be installed and removed even when the RAID system is powered
on and functioning.
To replace a disk, follow the procedures below:
1. Unlock and open the front panel door.
2. Push the button to release the tray handle.
3. Grab the handle and gently pull out the disk tray.
4. Unscrew the hard disk to detach it from the disk tray.
5. Replace with a new hard disk. To install the hard disk, see also
2.1 Installing the Hard Disks on page 2-7
for more
details.
6. Slide the disk tray back into the empty slot then push down the tray handle.
7. Close and lock the front panel door..
Note
To turn off the audible alert, simultaneously press the Up and Down buttons on the front panel
twice.
Note
Replace the hard disk with the same or greater capacity than the faulty disk. If the disk is smaller,
the audible alert will sound and the auto-rebuild function will not start.
