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.
