Power Supply LEDs
Two LEDs are provided on the power supply module: a DC LED indicating the operational status of outgoing power and an AC LED indicating incoming AC line voltage is sufficient or has fallen below operational limits. Refer to Figure 3‐35 for their location and Table 3‐1 for a description of LED function. Power supplies are installed in chassis slots PS1 through PS3 at the base of the chassis.
