MX2010 High-Voltage Universal (HVAC/HVDC) Power Supply Module LEDs
Each high-voltage second-generation universal (HVAC/HVDC) PSM faceplate contains four LEDs. These LEDs are shown in Figure 1 and Table 1. Nine bicolor LEDs, labeled 0 through 8 for the nine PSMs, are located in the center of the craft interface.
The primary input of the PSM is a dual redundant feed, INP0 and INP1. Both feeds are active during operation, and both feeds share load current when present. In addition, a PSM failure triggers the alarm LED on the craft interface.
