d. Replace with a new Hard Disk Drive
It must be same capacity or greater than the faulty drive, if you
replace with a Hard Disk Drive of insufficient capacity, the Disk
Array's built-in buzzer will sound and the intelligent Auto-Rebuild
function will not be started.
For best performance, we recommend you swap with an
identical Hard Disk Drive.
e. Gently slide-in the HDD tray and lock up to start
the Auto-Rebuild
When you have installed the replacement disk drive, screw in all
the screws and plug in the cables. You may now gently slide in
the HDD tray into the chassis and lock up it.
Data Auto-Rebuild will be started automatically when you lock up
the HDD tray.
