Problem 6: The switch functions intermittently.
Solutions: Check the system hardware status through the management
software:
Use the SHOW SYSTEM ENVIRONMENT command in the
Privileged Exec mode to verify that the input voltage from the
power source to the switch is stable and within the approved
operating range. The unit will shutdown if the input voltage
fluctuates above or below the approved operating range.
For switches that have a ventilation fan, use the SHOW SYSTEM
ENVIRONMENT command in the Privileged Exec mode to verify
that it is operating correctly.
Verify that the location of the switch provides adequate airflow. The
unit will shutdown if it is in danger of overheating.
