CSC/4 Processor Card LED Indicators—Front-Edge View
The three CSC/3 LEDs are shown in Figure 14. The far left, red, status LED goes on momentarily
during initialization, flashes if there is an error, and is off under normal conditions. The middle, red,
halt LED goes on only when the processor is in a halt state (which indicates an error). The far right
green OK LED lights at startup and remains on to indicate that the system software has booted and
is operational.
