Server warnings and cautions
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
WARNING:
To reduce the risk of personal injury, electric shockserver, or damage to the equipment, disconnect the
power cord to remove power from the . Pressing the Power On/Standby button does not shut off system
power completely. Portions of the power supply and some internal circuitry remain active until AC power
is removed.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible
power supply. This device protects the hardware from damage caused by power surges and voltage
spikes and keeps the system in operation during a power failure.
CAUTION:
Do not operate the server for long periods with the access open or removed. Operating the server in this
manner results in improper airflow and improper cooling that can lead to thermal damage.
Powering down the server
Before powering down the server for any upgrade or maintenance procedures, perform a backup of critical
server data and programs.
IMPORTANT:
When the server is in standby mode, auxiliary power is still being provided to the system.
To power down the server, use one of the following methods:
• Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server enters standby
mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the server to enter standby
mode.
This method forces the server to enter standby mode without properly exiting applications and the OS. If
an application stops responding, you can use this method to force a shutdown.
• Use a virtual power button selection through iLO.
This method initiates a controlled remote shutdown of applications and the OS before the server enters
standby mode.
Before proceeding, verify that the server is in standby mode by observing that the system power LED is
amber.
