2. Loosen the retaining screws that hold the chassis tray assembly.
3. Gently slide the chassis tray assembly forward to remove the tray from the appliance so you
can access the hard-disk drive retaining screws from the bottom of the tray.
Note
Because power to an IP390 appliance is automatically disconnected when the chassis
tray assembly is opened, you do not need to manually disconnect the power for this
procedure. Any servicing of the unit, however, should be completed with the chassis tray
assembly fully removed from the appliance. Power is still active in the chassis body and
care should be taken when working on the power supply or power supply wiring without
disconnecting the power cord.
