Core I/O LEDs
The core I/O LEDs in Table 4-6 are located on the bulkhead of the installed core I/O PCA. There
is a DIP switch on the core I/O card that is used to select which MP firmware set (indicated by
the MP SEL LED) is selected for loading. The DIP switch is only visible when the core I/O card
is removed from the system and is located in the center of the PCA.
