Figure 6 BPS-120 Front Panel STANDBY/ACTIVE
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.
