1.4.2 Emergency Power-off Considerations
If there is an emergency, then power to the Exalogic machine should be halted
immediately. The following emergencies may require powering off the Exalogic
machine:
• Natural disasters such as earthquake, flood, hurricane, tornado or cyclone.
• Abnormal noise, smell or smoke coming from the machine.
• Threat to human safety.
1.4.2.1 Emergency Power-off Procedure
To perform an emergency power-off procedure for the Exalogic machine, turn off
power at the circuit breaker or pull the emergency power-off switch in the computer
room. After the emergency, contact Oracle Support Services to restore power to the
machine.
1.4.2.2 Emergency Power-off Switch
Emergency power-off (EPO) switches are required when computer equipment
contains batteries capable of supplying more than 750 volt-amperes for more than five
minutes. Systems that have these batteries include internal EPO hardware for
connection to a site EPO switch or relay. Use of the EPO switch will remove power
from the Exalogic machine.
1.4.3 Cautions and Warnings
The following cautions and warnings apply to Exalogic machines:
• Do not touch the parts of this product that use high-voltage power. Touching
them might result in serious injury.
• Do not power off Exalogic machines unless there is an emergency. In that case,
follow the Emergency Power-off Procedure .
• Keep the front and rear cabinet doors closed. Failure to do so might cause system
failure or result in damage to hardware components.
• Keep the top, front, and back of the cabinets clear to allow proper airflow and
prevent overheating of components.
• Use only the supplied hardware.
