HP ProLiant DL320 G6 Server Maintenance and Service Guide

Removal and replacement procedures 25
WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the server.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
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
To access some components and perform certain service procedures, you must perform one or more of the
following procedures:
• Power down the server (on page 25).
If you must remove a server from a rack, power down the server.
• Remove the server from the rack (on page 26).
To access internal server components, remove the server from the rack.
Power down the server
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the power supply and some internal
circuitry remain active until AC power is removed.
IMPORTANT: If installing a hot-plug device, it is not necessary to power down the server.
1. Back up the server data.
2. Shut down the operating system as directed by the operating system documentation.
NOTE: If the operating system automatically places the server in Standby mode, omit the next
step.
3. Press the Power On/Standby button to place the server in Standby mode. When the server activates
Standby power mode, the system power LED changes to amber.
IMPORTANT: Pressing the UID button illuminates the blue UID LEDs on the front and rear panels.
In a rack environment, this feature facilitates locating a server when moving between the front and
rear of the rack.
