In general the BPS-120 may be in one of the following states: ACTIVE, STANDBY, or FAULT, as indicated by their corresponding front panel LEDs shown in Figure 6. The BPS-120 also includes advanced self-diagnostic monitoring features to ensure that its own circuitry is functioning normally; the PWR, TEMP, and FAN LEDs indicate these states. This information is described in Table 2.
