Optical ILA Power Supply LEDs
Each optical ILA power supply has two LEDs on the power supply faceplate. Figure 1 shows the location of the LEDs on an optical ILA AC power supply. Figure 2 shows the location of the LEDs on an optical ILA DC power supply.
1 — DC OK | 2 — AC OK |
1 — DC OUT OK | 2 — DC IN OK |
Use Table 1 and Table 2 to interpret the state of the power supply LEDs.
