FEP INITIALIZATION AND BUILT-IN SELF TEST
The CPCI-824 board displays on the IOP, ACT, STO and ST1 LEDs the status of the boards initial-
ization and diagnostic self test.
FEP initialization firmware illuminates various user LED patterns after completing early stages of
hardware initialization. Should the board fail to boot properly, the LED pattern will indicate the last
successfully completed stage of the board initialization sequence. The following table describes the
startup LEDs.
