Powering down the system
Two situations may arise when you need to power down the system:
• Emergency po
wer off
• Planned power off
For instructions in e ach of these situations, see the following procedures.
Emergency power off
The system does not have an emergency power off switch. In an emergency when it is
crucial to power off the system im m ed iately for safety reasons, remove power at the AC
branch circuit breakers in your facility that supply power to the system. Take care when
placing these breakers that they are clearly marked and easily accessible.
CAUTION:
Performing an emergency power off immediately shuts down the system, neglecting
the normal power off sequence. Jobs in process ar e aborted and their integrity
after recovery is not guaranteed. Use this power off method only in an emergency.
Afterwards, only a qualified HP support representative is allowed to restore power to
the system. Call your HP support representative immediately.
Emergency situations in which you should con sider performing the emergency power
off procedure are:
• A physical location catastrophe such as a flood, hurricane, tornado, or
earthquake
• Any circumstance that presents the threat of injury or death to a person
• You detect any smoke, abnormal loud noise, or smell com ing from the system.
