    4.4.2 Mounting procedure How the drive is mounted depends on the system cabinet structure. Determine the mounting procedure in consideration of the requirements of each system. This section contains the general mounting procedure and check items. See Section 3.2 for details on mounting drive. 1) For a system with an external operator panel mounted, connect the external operator panel cable before mounting the drive in the system cabinet because it is difficult to access the connector after the drive is mounted.

    Installation 4) After each cable connector is connected, secure the cable so that the cable does not touch the drive or the parts on the PCA or obstruct the flow of cooling air in the system cabinet. 1) Be careful of the insertion directions of SCSI connectors. For a system in which the terminating resistor power is supplied via the SCSI cable, connecting connectors in the wrong direction may cause the following:...
