You can determine the status of both the pedestal blowers and each power supply
by looking at the power supply LEDs (green) as shown in Figure 8-1. The left
LED displays the pedestal cooling status and the right LED displays the power
supply status. The LEDs indicate a fault when one of the following conditions
occur:
• A power supply fault
• A blower failure
• An ac input power problem
Figure 8–1 Power Supply LEDs
Tables 8-1 and 8-2 describe the power supply LED codes.
