Bit Assignments For Error Field - Compaq AlphaServer ES45 Service Manual

Model/Other Optional data. For Compaq FRUs, the Compaq part alias
number (if one exists). For vendor FRUs, the year and
week of manufacture.
Alias/Misc Miscellaneous information about the FRUs. For Compaq
FRUs, a model name, number, or the common name for the
entry in the Part # field. For vendor FRUs, the
manufacturer's name.
Table 4–3 lists bit assignments for failures that could potentially be listed in the
E (error) field of the show fru command. Because the E field is only two
characters wide, bits are "or'ed" together if the device has multiple errors. For
example, the E field for a FRU with both TDD (02) and SDD (04) errors would
be 06:
010 | 100 = 110 (6)
