d
tape drive and to the connector on the controller card (SAS or SCSI)
or the SATA connector on the system board.
Ensure that a power cable is properly connected to the drive and to
e
the power distribution board.
Close the system. See "Closing the System" on page 86.
f
Place the system upright and on its feet on a flat and stable surface,

reconnect the system to the electrical outlet, and turn on the system
and attached peripherals.
5 For SCSI tape drives, verify that the tape drive is configured for a unique
SCSI ID number and that the tape drive is terminated or not terminated,
based on the interface cable used to connect the drive.
See the documentation for the tape drive for instructions on selecting the
SCSI ID number and enabling or disabling termination.
6 Run the appropriate online diagnostics tests. See "Using Online
Diagnostics" on page 181.
