DR007: Resolve Barcode Scanner Issue

|
Problem:
The library has failed to scan one of the following system bar code labels:
v system serial number
v world wide name
v drive identification label
v module serial number
This problem IS NOT associated with failure to read a tape cartridge bar code label.
Troubleshooting Steps:
1. Select Tools → Service → Library → Barcode Test to help isolate the problem and determine if it is intermittent.
2. Run the test several times and note the results.
v If the test passes, the failure is most likely with a particular bar code label.
v If the test fails, the failure is most likely with the Picker Assembly that contains the bar code scanner.

DR008: Resolve Stuck I/O Station Interrupt

Problem:
The library control firmware receives continuous I/O station door state change events. Actual door open and
closure state changes can still be detected and cartridge inventory operations will still perform properly, but library
performance is affected.
Troubleshooting Steps:
1. Close the RAS ticket and power off the library.
2. Inspect the top and bottom library module terminators for bent or shorted connector pins. Re-attach if no
problem is found.
3. If the library consists of multiple modules, inspect all module-to-module cables for bent or shorted connector
pins. Re-attach if no problem is found.
4. If a defective connector is found, call Service for part replacement.
5. If no issue is found, power on the library and wait for the library to initialize. Open and close each I/O station
door. If the RAS ticket is displayed again, contact Service.

DR009: Resolve AC Failure

Problem:
The facility AC power appears to be failed on a power supply. This can be the result of the facility power actually
being OFF, the power switch on the power supply being turned OFF, or an actual failure in the power supply.
Troubleshooting Steps:
1. Check the facility AC power and make sure the power supply is properly seated and the power switch is on.
2. Inspect all module terminators for any broken or bent pins.
3. If the library consists of multiple modules, inspect all module-to-module cables for any broken or bent pins.
4. If the facility AC power and the power supply power switch are OK, see "Power Supply (Primary and
Redundant)" on page 8-52.
