• The CPU module has internal fault LEDs for CPUs and DIMMs on the CPU module board. POST and
runtime error detection routines are stored in on-board registers. The contents of the registers are preserved
for a limited time by a supercap voltage source.
To operate the LEDs, press switch SW1 on the board after the CPU module is removed from the chassis.
