The following figures show how to locate parts In the 3480 documentation, uSing the identifying numbers that are shown in "Examples of the Second Format" on LGND 10.

For the part location area that IS used in the logics, the figures show where they are located In the 3480 subsystem by referencing the

"Table of Contents" entry In the LOC and CARR sections of the Maintenance Information. The LOC and CARR sections "Table of Contents" may not be the exact name or FRU number of the part referenced in the logiC, however the page referenced by the "Table 01 Contents" will relate to the part you are looking for.

These figures also show where a part can be found in the logiCS. For example, if the power is suspected to be a problem, you can look for power parts (CBs, Power Supplies, and so forth) and find the logic pages that show these areas.
