2-2 HP ProLiant DL320 Generation 3 Server Maintenance and Service Guide

WARNING: When installing the server in a telco rack, make certain that the rack frame is adequately secured to the building structure at the top and bottom.

WARNING: To reduce the risk of personal injury or damage to the equipment, at least two people are needed to safely unload the rack from the pallet. An empty 42U rack weighs 115 kg (253 lb), is over 2.1 m (7 ft) tall, and may become unstable when being moved on its casters. Do not stand in front of the rack as it rolls down the ramp from the pallet. Handle the rack from both sides.

Server Warnings and Precautions

WARNING: To reduce the risk of personal injury from hot surfaces, allow the hot-plug drives and the internal system components to cool before touching them.

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.

Unplug the power cord from the power supply to disconnect power to the equipment.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a

regulating uninterruptible power supply (UPS). This device protects the hardware from damage caused by power surges and voltage spikes and keeps the system in operation during a power failure.

CAUTION: The server cooling is not achieved if the system access panel is removed.

must always be operated with the system access panel closed. Proper

Removal and Replacement Procedures

Use the procedures in this section to perform service events on the ProLiant DL320 G3 Server.

HP ProLiant DL320 Generation 3 Server Maintenance and Service Guide 2-3

Removal and Replacement Procedures

Powering Down the Server

The server does not completely power down when the front panel power button is pressed. The button toggles server power between On and Standby. In Standby, the server removes power from most electronics and drives, portions of the power supply and some internal circuitry remain active. To completely remove all power from the system, disconnect the power cord from the server.

WARNING: To reduce the risk of injury from electric shock, remove the power cord to completely disconnect power from the system.

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that only one component is extended at a time. A rack may become unstable if more than one component is extended at the same time.

WARNING: Because the rack allows you to stack computer components in a vertical rather than a horizontal plane, you must take precautions to provide for rack stability and safety to protect both personnel and property. Heed all cautions and warnings throughout the installation instructions that come with the server.

WARNING: To reduce the risk of personal injury or damage to the equipment, place the server on a sturdy table or workbench whenever it is removed from the rack for device accessibility. Refer to the HP ProLiant DL320 Generation 3 Server User Guide for further information on working with racks.

CAUTION: Moving the Power On/Off switch to the Off position does not completely remove

system power. Some portions of the power supply and some internal circuitry remain active. Disconnect all power cords from the server to remove all power from the system.

CAUTION: ESD can damage electronic components. Be sure you are properly grounded before beginning any installation procedure. For more information, see “Electrostatic Discharge Information” in this chapter.

NOTE: Microsoft® Windows NT® users may use the Power Down Manager to power down the server. For information on this system utility, refer to the NTREADME.HLP file on the NT Software Support Diskettes.

2-4 HP ProLiant DL320 Generation 3 Server Maintenance and Service Guide

To power down the server:

1. Press the power button to toggle the server to standby. The power LED on the power button changes from green to amber.

2. Listen for the fan noise to stop to indicate that the server is powered down.

3. Disconnect the power cord first from the AC outlet and then from the server. The power LEDs turn off.

4. Disconnect all remaining cables on the server rear panel, including cables extending from external connectors on expansion boards.

5. Remove the server from the rack and position it securely on a workbench or other solid surface for stability and safety.

Access Panel

To access the system board, processor, memory modules, expansion slot, and other internal components, remove the access panel. Observe the following warnings and cautions.

Removal and Replacement Procedures

WARNING: The front panel Power On/Off switch does not completely shut off all system power. Portions of the power supply and some internal circuitry remain active until AC power is removed.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching them.

CAUTION: Do not operate the server without the access panel installed. The access panel is

required for proper airflow. Operating the server without the access panel prevents proper airflow and results in improper cooling and possible thermal damage.

CAUTION: Before removing the server access panel, be sure that the server is powered down and that the power cord is disconnected from the server and the electrical outlet.

CAUTION: To avoid the risk of damage to the system or expansion boards, remove all power cords before installing or removing expansion boards. When the Power On/Off switch is in the Off position, auxiliary power is still connected to the PCI expansion slot and may damage the card.

CAUTION: ESD can damage electronic components. Ensure proper grounding before beginning any installation procedure.
