Detection Scenario At library power ON, the robot attempts to scan all module bar code labels.
When the OID number on each label is read, the embedded branding
information is compared to persistent data on the system compact flash.
Root Causes
1. Various manufacturing defect errors, mislabeling or part mix ups.
2. Spare part logistics error where wrong module FRU or compact flash
FRU is sent to a customer site.
3. End users or Service personnel mixing and matching hardware from
multiple systems of different branding in the field.
4. Malicious intent where customers attempt to buy and combine hardware
from different sources.
5. Bar code reader is not scanning the labels correctly.

T082: Volume Serial Scanner Failure
Description GUI Description: The library volume serial scanner is not operating properly.
Explanation: The volume serial scanner is detected to be in a state where the
library control logic cannot use it. Library robot power is known to be
applied (door is closed and robot is detected to be functioning enough to
confirm power is applied) and yet scanner communication cannot be
established at all or appears to be not healthy.
Detection Scenario
1. During any library power ON or door close operation, Picker power is
applied and bar code scanner communication is established.
2. During run time operations such as inventory where the bar code scanner
is used.
Root Causes
1. Scanner is physically disconnected
2. Various electrical hardware failures that prevent proper communication
between the Library Control Blade and bar code scanner.
3. Bar code reader is not scanning the labels correctly.
Possible CRU Replacements Library Control Blade
Possible FRU Replacements Note: Read and perform all resolution steps before dispatching any parts.
Dispatch the first part listed below for replacement. If this does not solve the
problem, dispatch the second part, and so on, in order. Dispatch only one
part (or set of parts) at a time.
