3.2 Monitoring the Controllers
Each controller has 11 status LEDs (Figure 26). The LEDs are defined in Table 2.

When a fault condition occurs on a controller, the enclosure LEDs indicate an enclosure
fault. Because the controllers are on the back of the enclosure where they may be hard to
see, always check controller status whenever the enclosure LEDs indicate a fault.
When the controller Fault LED illuminates, replace the controller (see Section 4.2).
