ProLiant DL 380 Maintenance and Service Guide

2-4 Compaq ProLiant DL380 Maintenance and Service Guide
Preparation Procedures
Before beginning to remove any serviceable parts, determine whether the part is hot-pluggable
or non-hot-pluggable.
Hot-Pluggable Device
Hot-pluggable devices in the ProLiant DL380 Server include SCSI hard drives and
power supplies.
IMPORTANT: It is not necessary to turn off the server to replace hot-plug devices such as power
supplies, fans, or hard drives when they are not in active use.
Non-Hot-Pluggable Device
If the part is non-hot-pluggable, the server must be powered down. Non-hot-pluggable parts
include the processors, all boards, DIMMs, fans, and drive cages.
Powering Down the Server
System power in ProLiant DL380 Servers does not completely shut off with the front panel
Power On/Standby switch. The switch toggles between On and Standby, rather than On and Off.
The standby position removes power from most electronics and the drives, but portions of the
hot-plug power supply and some internal circuitry remain active. To completely remove all
power from the system, you must disconnect all power cords from the server.
WARNING: To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
WARNING: To reduce the risk of personal injury or damage to the equipment, ensure that only
one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING: Because the rack allows you to stack computer components in a vertical rather
than a horizontal plane, you must take precautions to provide for rack stability and safety to
protect both personnel and property. Heed all cautions and warnings throughout the installation
instructions that came with the server.
WARNING: To reduce the risk of personal injury or damage to the equipment: If the server is
removed from the rack for device accessibility, remove the server from the rack and place it on
a sturdy table or workbench. Refer to the ProLiant DL380 Server Setup and Installation Guide
for further information on working with racks.
CAUTION: The system power in the server does not completely shut off from the front
Power On/Standby switch. Moving the switch from On to Standby leaves some portions of the
hot-plug power supply and some internal circuitry active. Disconnect all power cords from the
server to remove all power from the system.
