Removal and Replacement Procedures 2-5 Non-Hot-Pluggable Device Power must be removed from the server to remove or replace non-hot-pluggable devices. Non-hot-pluggable parts include the processors, all boards, DIMMs, and drive cages. See "Powering Down the Server" for complete power-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. Powering Down the Server Before beginning any of the removal and replacement procedures for non-hot-plug devices: 1. Press the Power On/Standby switch. This places the server in standby mode, thereby disabling the main power supply output and providing auxiliary power (+5V) to the server. 2. Verify that the power status LED indicator on the front panel, located nearest to the Power On/Standby switch, is amber and that the fans have stopped spinning. IMPORTANT: It is not necessary to power down the server to replace hot-plug devices such as power supplies, fans, or SCSI hard drives when they are not in active use. 3. Disconnect all AC power cords from the AC outlets, then from the server. WARNING: To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system. 4. Disconnect all external peripheral devices from the server. 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. 5. For stability and safety, properly positioning the server is critical. If the server is mounted in a rack, remove the server from the rack and place it on a sturdy table or workbench. To reduce the risk of personal injury or damage to the equipment, see "Rack Warnings" later in this chapter. Refer to the Compaq ProLiant ML530 Setup and Installation Guide for further information on working with racks. 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, 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.

disabling the main power supply output and providing auxiliary power (+5V) to the
server.
2.
Verify that the power status LED indicator on the front panel, located nearest to the
Power On/Standby switch, is amber and that the fans have stopped spinning.
IMPORTANT:
It is not necessary to power down the server to replace hot-plug devices such as power
supplies, fans, or SCSI hard drives when they are not in active use.
3.
Disconnect all AC power cords from the AC outlets, then from the server.
WARNING:
To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
4.
Disconnect all external peripheral devices from the server.
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.
5.
For stability and safety, properly positioning the server is critical.
■
If the server is mounted in a rack, remove the server from the rack and place it on a
sturdy table or workbench. To reduce the risk of personal injury or damage to the
equipment, see
“

later in this chapter. Refer to the
Compaq
ProLiant ML530 Setup and Installation Guide
for further information on working
with racks.
