The DC-input power supply LEDs include the input power LED and the out fail LED. See Figure 8-10. The green input power LED is on when the input power is applied. The yellow out fail LED is normally off but flashes at power on for a lamp test.

The out fail LED goes on if the power supply shuts down for either of the following reasons:

Power supply DC-output failure, which could be caused by loss of DC-input power (input line failure or operator turned off system power) or an actual failure in the DC-input power supply

Power supply shutdown, initiated by the power supply because it detected an out-of-tolerance temperature or voltage condition in the power supply
