5. Look at the PDU and PSM LEDs on the craft interface.
6. If both PDUs fail, the system temperature might have exceeded the threshold, causing the system to
shut down. If the temperature exceeds the acceptable maximum, the Control Board turns off the
PDUs.
7. Check the temperature of components that are monitored for temperature alarms by issuing the show
chassis environment monitored command. For more information about temperature alarms, see Table 87
on page 589 .
Verify that the status of each component is OK .
