Preparation Procedures; Powering Down The Server - HP ProLiant ML350 Generation 4 Maintenance And Service Manual

Preparation Procedures

To access some components and perform certain service procedures, you must
perform one or more of the following procedures:
•
Extend the server from the rack ("Extending the Server from the Rack" on
page 16).
If you are performing service procedures in a Compaq branded rack, telco
rack, or third-party rack cabinet, you can use the locking feature of the rack
rails to support the server and gain access to internal components.
For more information about telco rack solutions, refer to the
RackSolutions.com website (http://www.racksolutions.com/hp).
•
Power down the server ("Powering Down the Server" on page 15).
If you must remove a server from a rack or a non-hot-plug component from a
server, power down the server.
•
Remove the server from the rack ("Removing the Server from the Rack" on
page 18).
If the rack environment, cabling configuration, or the server location in the
rack creates awkward conditions, remove the server from the rack.

Powering Down the Server

WARNING: When installing a server in a telco rack, be
sure that the rack frame is adequately secured to the top and
bottom of the building structure.
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.
