2-4 Compaq ProLiant DL580 Server Maintenance and Service Guide Preparation Procedures The system power in the ProLiant DL580 server does not completely power down 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 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. For more information about removing power from the system, see "Powering Down the Server" later in this chapter. See "Server Warnings and Precautions" later in this chapter for further safety information. IMPORTANT: Before beginning to remove any serviceable part, determine whether the part is hot-pluggable or non-hot-pluggable. Hot-pluggable devices in the ProLiant DL580 server include SCSI hard drives, fans, and power supplies. Hot-Pluggable Parts If it is hot-pluggable, do not perform a power shutdown of the server. The access panel can be removed without causing system shutdown. Hot-pluggable devices in the ProLiant DL580 server include Wide Ultra2 and Ultra3 SCSI hard drives, some expansion boards, fans, and power supplies. IMPORTANT: It is not necessary to power down the server to replace hot-plug devices such as power supplies, fans, or PCI Hot Plug boards when they are not in active use. Non-Hot-Pluggable Parts If the part is non-hot-pluggable, the server must be powered down. Non-hot-pluggable parts include the processors, some expansion boards, the peripheral board, DIMMs, and drive cages. See "Powering Down the Server" for complete powering down instructions. WARNING: To reduce the risk of personal injury or damage to the equipment, the installation of options other than hot-plug power devices should be performed only by individuals who are qualified in servicing computer equipment and trained to deal with products capable of producing hazardous energy levels. WARNING: To reduce the risk of personal injury or damage to the equipment when moving the server, be sure that: The access panel is securely fastened to the chassis. You do not use the system board tray handle to move the unit. You do not use the rack-mount bezel handles to move the unit.

Compaq ProLiant DL580 Server Maintenance and Service Guide
Preparation Procedures
The system power in the ProLiant DL580 server does not completely power down 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 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. For more information
about removing power from the system, see “Powering Down the Server” later in this chapter.
See “Server Warnings and Precautions” later in this chapter for further safety information.
IMPORTANT:
Before beginning to remove any serviceable part, determine whether the part is
hot-pluggable or non-hot-pluggable. Hot-pluggable devices in the ProLiant DL580 server include SCSI
hard drives, fans, and power supplies.
Hot-Pluggable Parts
If it is hot-pluggable, do not perform a power shutdown of the server. The access panel can be
removed without causing system shutdown. Hot-pluggable devices in the ProLiant DL580
server include Wide Ultra2 and Ultra3 SCSI hard drives, some expansion boards, fans, and
power supplies.
IMPORTANT:
It is not necessary to power down the server to replace hot-plug devices such as power
supplies, fans, or PCI Hot Plug boards when they are not in active use.
Non-Hot-Pluggable Parts
If the part is non-hot-pluggable, the server must be powered down. Non-hot-pluggable parts
include the processors, some expansion boards, the peripheral board, DIMMs, and drive cages.
See “Powering Down the Server” for complete powering down instructions.
WARNING:
To reduce the risk of personal injury or damage to the equipment, the installation
of options other than hot-plug power devices should be performed only by individuals who are
qualified in servicing computer equipment and trained to deal with products capable of
producing hazardous energy levels.
WARNING:
To reduce the risk of personal injury or damage to the equipment when moving the
server, be sure that:
■
The access panel is securely fastened to the chassis.
■
You do not use the system board tray handle to move the unit.
■
You do not use the rack-mount bezel handles to move the unit.
