2-4 Compaq ProLiant 8000 Intel Pentium III Xeon 700MHz Servers Maintenance and Service Guide Turning Off the Server The ProLiant 8000 server's Power On/Standby switch does not shut off the system power completely. The switch functions as On and Standby, rather than On and Off. Standby mode removes power from most of the electronics and the drives, but portions of the power supply and some internal circuitry remain active. IMPORTANT: To completely remove all power from the system, you must disconnect the power cord from the server. In systems with multiple power supplies, you must disconnect all power cords to completely remove power from the system. IMPORTANT: It is not necessary to turn off the server to replace hot-plug devices, such as PCI Hot Plug power supplies or hot-plug fans. 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. Before beginning any removal and replacement procedure for non-hot-plug devices: 1. Press the Power On/Standby switch to Standby mode. This disables the main power supply output and provides auxiliary power (+5V) to the server. Standby does not disable main AC power. 2. Verify that the system LED on the front panel, near the Power On/Standby switch, is off and that the fan noise abates. 3. Disconnect all power cords from the server. 4. For some removal and replacement procedures, you must remove the server from the rack and place it on a sturdy table or workbench. Refer to the Compaq ProLiant 8000 Setup and Installation Guide for instructions. 46 - 109 kg 100 - 240 lb WARNING: To reduce the risk of personal injury or damage to the equipment: Observe local Occupational Safety requirements and guidelines for heavy equipment handling. Obtain adequate assistance to lift and stabilize the product during installation or removal. Remove all pluggable power supplies and modules to reduce the weight of the product. Stabilize the server by keeping the unit on the rails. WARNING: Because the rack allows you to stack computer components on a vertical rather than horizontal plane, you must take precautions to provide for rack stability and safety. These precautions also protect both personnel and property. Follow all cautions and warnings throughout the installation instructions that came with the server.

Compaq ProLiant 8000 Intel Pentium III Xeon 700MHz Servers Maintenance and Service Guide
Turning Off the Server
The ProLiant 8000 server’s Power On/Standby switch does not shut off the system power
completely. The switch functions as On and Standby, rather than On and Off. Standby mode
removes power from most of the electronics and the drives, but portions of the power supply
and some internal circuitry remain active.
IMPORTANT:
To completely remove all power from the system, you must disconnect the power cord
from the server. In systems with multiple power supplies, you must disconnect all power cords to
completely remove power from the system.
IMPORTANT:
It is not necessary to turn off the server to replace hot-plug devices, such as PCI Hot
Plug
power supplies or hot-plug fans.
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.
Before beginning any removal and replacement procedure for non-hot-plug devices:
1.
Press the Power On/Standby switch to Standby mode. This disables the main power
supply output and provides auxiliary power (+5V) to the server. Standby does not disable
main AC power.
2.
Verify that the system LED on the front panel, near the Power On/Standby switch, is off
and that the fan noise abates.
3.
Disconnect all power cords from the server.
4.
For some removal and replacement procedures, you must remove the server from the rack
and place it on a sturdy table or workbench. Refer to the
Compaq ProLiant 8000 Setup
and Installation Guide
for instructions.

To reduce the risk of personal injury or damage to the equipment:
■
Observe local Occupational Safety requirements and guidelines for heavy
equipment handling.
■
Obtain adequate assistance to lift and stabilize the product during installation or
removal.
■
Remove all pluggable power supplies and modules to reduce the weight of the
product.
■
Stabilize the server by keeping the unit on the rails.

than horizontal plane, you must take precautions to provide for rack stability and safety. These
precautions also protect both personnel and property. Follow all cautions and warnings
throughout the installation instructions that came with the server.
