Removal and Replacement Procedures 2-5
Powering Down the Server
Before beginning any of the removal and replacement procedures for non-hot-pluggable
devices:
1. Press the Power On/Standby switch. This switch places the server in standby mode that
disables the main power supply output and provides only auxiliary power (+5V) to
the server.
2. Verify that the Power On/Standby switch power LED indicator is amber and that the fans
are off.
3. Disconnect all AC power cords from the AC outlets, and then disconnect 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.

WARNING: To reduce the risk of personal injury or damage to the equipment,
observe local occupational health and safety requirements and guidelines for
manual material handling.
IMPORTANT: It is not necessary to power down the server to replace hot-pluggable components such as
power supplies, CPU and I/O fans, or PCI Hot Plug boards when they are not in active use.
NOTE: It is necessary to be knowledgeable of electrostatic discharge information before performing the
preparation procedures. For electrostatic discharge information, see “Electrostatic Discharge
Information” earlier in this chapter.
5. Position the server as follows to ensure stability and safety:
G 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 ML570 Server Setup and Installation Guide for further information
on working with racks.
G 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.
