WARNING: Fan failure
has been detected
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:
"About the Status and Control Panel" on page 8
"Front Panel LEDs" on page 242
"Power Supply LEDs" on page 245
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 42). To recover from an automatic shutdown, you
must disconnect the AC power cord, wait approximately 10 seconds, and then
reconnect the power cord.
