2-4 Compaq ProLiant ML530 Servers Maintenance and Service Guide Preparation Procedures System power in Compaq ProLiant ML530 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 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 section. See "Server Warnings and Precautions" later in this section for further safety information. 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. You do not use the tower front bezel door as a handle to move the unit. IMPORTANT: Before beginning to remove any serviceable parts, determine whether the part is hot-pluggable or non-hot-pluggable. Hot-pluggable devices in Compaq ProLiant ML530 servers include SCSI hard drives, fans, and power supplies. IMPORTANT: Before powering down the unit, verify devices to be replaced by checking the LED indicator status. LED indicators will no longer be lit after power is removed from the system. Hot-Pluggable Device The server can remain on to remove and replace hot-plug devices. The access panel can be removed without causing a system shutdown. Hot-pluggable devices will have port-colored latches. Hot-pluggable devices in Compaq ProLiant ML530 servers include SCSI hard drives, fans, and power supplies. CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning any installation procedure. See "Electrostatic Discharge Information" earlier in this chapter. IMPORTANT: If the server is a tower model, either lock the casters for stability when removing the access panel, or place the server on its side with the access panel up. To reduce the risk of personal injury or damage to the equipment, see "Server Warnings and Precautions" later in this chapter. IMPORTANT: If the server is mounted in a rack, accessibility to hot-pluggable devices can be increased by sliding the server partially out of the rack. To reduce the risk of personal injury or damage to the equipment, see "Rack Warnings" and "Server Warnings and Precautions" later in this chapter.

Compaq ProLiant ML530 Servers Maintenance and Service Guide
Preparation Procedures
System power in Compaq ProLiant ML530 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 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 section.
See “Server Warnings and Precautions” later in this section for further safety information.
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.
■
You do not use the tower front bezel door as a handle to move the unit.
IMPORTANT:
Before beginning to remove any serviceable parts, determine whether the part is
hot-pluggable or non-hot-pluggable. Hot-pluggable devices in Compaq ProLiant ML530 servers include
SCSI hard drives, fans, and power supplies.
IMPORTANT:
Before powering down the unit, verify devices to be replaced by checking the LED
indicator status. LED indicators will no longer be lit after power is removed from the system.
Hot-Pluggable Device
The server can remain on to remove and replace hot-plug devices. The access panel can be
removed without causing a system shutdown. Hot-pluggable devices will have port-colored
latches. Hot-pluggable devices in Compaq ProLiant ML530 servers include SCSI hard drives,
fans, and power supplies.
CAUTION:
Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure. See “Electrostatic Discharge
Information” earlier in this chapter.
IMPORTANT:
If the server is a tower model, either lock the casters for stability when removing the
access panel, or place the server on its side with the access panel up. To reduce the risk of personal
injury or damage to the equipment, see “Server Warnings and Precautions” later in this chapter.
IMPORTANT:
If the server is mounted in a rack, accessibility to hot-pluggable devices can be increased
by sliding the server partially out of the rack. To reduce the risk of personal injury or damage to the
equipment, see “Rack Warnings” and “Server Warnings and Precautions” later in this chapter.
