Identifying the monitor and subsystems
This explanation of the monitor labeling is provided to assist you in identifying these
particular parts by serial number. The part numbers appearing on the labels are internal
part numbers and will not be found in the list of field replaceable units (FRUs) included in
this manual.
Future revisions of a part may not always be backward compatible with a legacy part. To
determine the correct replacement part for your unit always provide the serial number
and model when ordering.
