Step 7 Move the chassis power switch to the Standby position.
The fans in the power supply modules will continue to run even if the chassis power switch is in the Standby
position.
Note
After powering off the controller, wait for a minimum of 30 seconds before powering it on again.
Note
Environmental Monitoring and Reporting Functions
Environmental monitoring and reporting functions allow you to maintain normal system operation by identifying
and resolving adverse conditions prior to loss of operation.
To prevent overheating of the chassis, ensure that your system is drawing cool inlet air. Over temperature
conditions may occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance
around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust
air exits the chassis and is not drawn into the inlet vent of another device.
Caution
Alarm Monitoring
The controller displays the CRIT, MAJ, and MIN alarm indicator LEDs. These LEDs indicate controller status
at all times, but you must directly observe these LEDs to become aware of a controller alarm condition.
Additionally, you can use the show facility-alarm status command to view the alarms.
To clear the the alarm LED, you need to shutdown the ports which are not connected.
Note
To clear a visual alarm, you must resolve the alarm condition. The clear facility-alarm command does not
clear an alarm LED on the controller.
Environmental Monitoring
The environmental monitoring functions use sensors to monitor the temperature of the cooling air as it moves
through the chassis.
The local power supplies provide the ability to monitor:
• Input and output voltage
