38 Hardware Installation
System Power-on
At power-on, for the first few seconds the unit performs a sequence of diagnostic tests called Power-
On Self Tests (POST). POST also includes a loop-back test of the robotics cabling.
After the POST sequence completes successfully, the library will respond to SCSI selections. Then
the system starts a series of initialization functions, a process that consists of robot calibration
operations and cartridge inventory of magazines and drive. The barcode labels on the cartridges will
be read when running inventory.
During these operations, the library continuously shows the map status on the screen. The status of
all magazine slots and the drives are initially unknown, and a question mark (?) is displayed for each
slot. As the robot searches the magazine slots for cartridges during inventory, the display is updated.
Note
You should turn on the power at least 60 seconds before the computer system is
started. The tape drive needs up to 60 seconds after power-on until it is active on
the SCSI bus.
Note
If the self-diagnostics and the inventory sequence are successfully completed,
the green LED illuminates and the display returns to the home screen. The library
is now ready for further configuration and operation.
If a problem occurs during the power-on sequence, the StorageLibrary displays an error message on
the display. Please refer to Troubleshooting to learn the procedures for resolving the problem.
