HP ProLiant DL560 Gen10, Maintenance And Service Manual

Page: 33 / 125

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 panel open or removed. Operating the server
in this manner results in improper airflow and improper cooling that can lead to thermal damage.
Preparation procedures
Power 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.
Extend the server from the rack
WARNING:
To reduce the risk of personal injury or equipment damage, be sure that the rack is adequately stabilized
before extending a component from the rack.
1. Pull down the quick release levers on each side of the server.
2. Extend the server from the rack.
