1.4.2 Power/Fan Tray Indicators
Figure 1–13 shows the ten indicators located on the PDA power/fan tray rear
panel. These indicators provide information about the power/fan tray. They
show the status of some part of the power/fan tray and are green during normal
operation. If a failure is detected, the corresponding indicator changes to red, and
the power tray shuts down. Any red indicators are latched ON, indicating the
problem area, and initiate the power shutdown.
