1) The replacement library enclosure will power up with theReady/Activity LED (1 in Figure 10-20 on page 10-22) ON.2) Power OFF the replacement library enclosure.3) Unplug the power cord from the power source then from the library.4) Proceed to “Swapping Library Controller Cards.”b. If power ON is not successful, contact Technical Support for furtherinstructions.Swapping Library Controller CardsIMPORTANT - READ ME BEFORE CONTINUINGThe Library Enclosure contains a copy of the vital product data (VPD) for your library. The VPD contains yourcurrent library configuration. A primary copy of this VPD is contained within the Library Controller Card. A backupcopy of this VPD is maintained on the accessor in the enclosure (or chassis). When the Library Enclosure isreplaced, the new enclosure electronics should contain zeros (0's) in key VPD locations. Upon detection of thesezeros, the library will automatically write VPD data to the replacement library enclosure from the primary copy ofthe VPD contained in the Library Controller Card. In rare occurrences, the replacement library enclosure maycontain valid (non-zero) VPD data left over from having been installed previously in another library. If this occurs,the library firmware, which is expecting to see zeros in the VPD area, will instead detect valid VPD data, and willnot know which copy of the VPD is the correct one. It will detect this VPD mismatch and display a messageentitled “VPD Selection” on the Operator Control Panel. The library will need your input to determine which copyof VPD to write to the replacement library enclosure. If you are replacing both the Library enclosure and theLibrary Controller Card, transfer VPD after installing one part before installing the other.If the message “VPD Selection” is displayed at the Operator Control Panel, carefully highlight the “VPD fromController” option before selecting OK. This will copy VPD from the controller to the replacement library enclosure.1. Swap the Library Controller Card in the defective library with the LibraryController Card in the replacement library enclosure.a. Remove the Library Controller Card (see Figure 10-19 on page 10-21) in thedefective library and in the replacement library enclosure.
