Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To prevent
electrostatic damage,
■ Transport products in static-safe containers, such as conductive tubes, bags, or boxes.
■ Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
■ Cover workstations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
■ Keep the work area free of nonconductive materials, such as ordinary plastic assembly
aids and foam packing.
■ Always be properly grounded when touching a static-sensitive component or assembly.
■ Avoid touching pins, leads, or circuitry.

Preparation Procedures
Hot-Pluggable Components
Before the removal of any serviceable part, determine whether it is hot-pluggable or
non-hot-pluggable. If it is hot-pluggable, do not perform a power shutdown of the server. The
access panels can be removed while the server is turned on without system shutdown. When the
server is in Standby mode, portions of the power supply, auxiliary power (+5V), and some
internal circuitry remain active.
Non-Hot-Pluggable Components
If the part is non-hot-pluggable, shut down the server. Non-hot-pluggable parts include the
processor, Processor Power Module, system board, memory board, Dual Inline Memory
Modules (DIMMs), peripheral board, and modem. Refer to “Powering Down the Server” later
in this chapter for complete power-down instructions.
WARNING: To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
Removal and Replacement Procedures 2-3
Powering Down the Server
System power in the ProLiant 6400R Server does not completely shut off with the front panel
Power On/Standby switch. The two positions of the switch function as On and Standby, rather
than On and Off. The Standby position 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 the 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 power
supplies, fans, or PCI Hot Plug boards.
Before beginning any of the removal and replacement procedures for non-hot-plug devices,
1. Move the Power On/Standby switch to the Standby position.
2. Disconnect the AC power cord from the AC outlet and then from the server.
3. Disconnect all external peripheral devices from the server.
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 ProLiant 6400R Setup and Installation
Guide for instructions.
2-4 Compaq ProLiant 6400R Maintenance and Service Guide
WARNING: Because the rack allows stacking of computer components on a vertical rather
than horizontal plane, ensure that precautions have been taken to provide for rack stability and
safety. It is important to follow these precautions to provide rack stability and safety and to
protect both personnel and property. Heed all cautions and warnings throughout the installation
instructions that came with the server.
WARNING: To reduce the risk of personal injury, always ensure that the rack is adequately
stabilized before extending a component outside the rack. A rack may become unstable if more
than one component is extended for any reason. Extend only one component at a time.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
■ The leveling jacks are extended to the floor.
■ The full weight of the rack rests on the leveling jacks.
■ The stabilizers are attached to the rack if it is a single rack installation.
■ The racks are coupled together in multiple rack installations.
CAUTION: Electrostatic discharge can damage electronic components. Ensure proper
grounding before beginning any installation procedure. For more information, refer to the
“Electrostatic Discharge” section earlier in this chapter.
Server Warnings and Precautions
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
WARNING: To reduce the risk of electric shock or damage to the equipment,
■ Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
■ Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
■ Disconnect power from the server by unplugging the power cord from either the electrical
outlet or the server.
This symbol indicates that the component exceeds the recommended weight for one
