3.4 Monitoring the APC Units

Each APC unit has four LEDs that indicate status (Figure 28) as described in Table 4 below.

When a failure occurs on an APC unit, the enclosure LEDs (see Section 3.1) indicate an

enclosure fault. Because the APC units are on the back of the enclosure where they may be

hard to see, always check the APC unit status whenever the enclosure LEDs indicate a fault.
