TS3310 Tape Library Setup and Operator Guide
1. At first boot up from clear to ship, the library must
establish the WWN for the first time. There may be no
WWN in system memory at this point.
2. Any power up. System memory already has a WWN
established for the Library Control Blade.
3. The Library Control Blade is improperly swapped into
a different physical chassis and the system reads the
physical chassis WWN label.
1. The Library Control Blade has been swapped between
libraries.
2. WWN label is damaged.
3. Bar code scanner is not working properly.
4. Entire communication path to bar code scanner is not
working properly.

Perform "DR007: Bar Code Scanner Diagnostic (a Library
Verify Test)" on page 11-36.
Before you replace a library component, refer to
"Diagnosing a Problem" on page 10-2 for additional
diagnostic procedures.
The library encounters an error which appears to be
isolated to hardware on the Library Control Blade itself.
Code detects a board level voltage problem.
Board level voltage problems.

v Observe library component LEDs (refer to "Interpreting
LEDs" on page 10-6.
v Refer to instructions to remove and replace the Library
Control Blade (see "Removing/Replacing the Library
Control Blade and Compact Flash Card" on page 12-18).
The library detects that the 42V, F3 picker power fuse
located on the LCB has blown.
Monitoring of voltage divider indicates partial or complete
voltage drop
1. Board level hardware failures
2. Permanent or temporary short in cables, connectors,
