If the environmental monitoring system detects a temperature problem, it also lights
the temperature LED on the status and control panel. If it detects a power supply
problem, it lights the power supply fault LED on the panel. The LEDs located on the
power supplies themselves will help to further identify the problem. For information
about system LEDs, see:

Note - Enterprise 250 power supplies will shut down automatically in response to
certain over-temperature and power fault conditions (see “Environmental Monitoring
and Control” on page 71). To recover from an automatic shutdown, you must
disconnect the AC power cord, wait approximately 10 seconds, and then reconnect
the power cord.
