Gently shake the connectors of the optical
cables by hand that link between NC and
drive unit or between drive units to check for
loosening and disconnection.
Also check if an excessive force is not
applied on them. The connector is loose or nearly
disconnected. The tab of the connector is
damaged.
Correctly install.
Replace the cable.
The connector is not disconnected. Check the investigation item No. 2.
