Removal and Replacement Procedures

This chapter provides subassembly/module-level removal and replacement procedures for HP ProLiant ML570 Generation 2 servers. After completing all necessary removal and replacement procedures, run the Diagnostics program to be sure that all components operate properly.

You need the following items for some procedures:

Torx T-15 tool

•

Torx T-10 tool

•

Diagnostics Utility from the SmartStart CD

•

Wrist strap

•

Safety Considerations

Before performing service procedures, review the following safety information.

Electrostatic Discharge

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. Use a wrist strap connected

•

to the work surface and properly grounded (earthed) tools and equipment. Keep work area free of nonconductive materials such as ordinary plastic assembly aids

•

and foam packing. Be sure that you are properly grounded (earthed) when touching a static-sensitive

•

component or assembly. Avoid touching pins, leads, or circuitry.

•

Use nonconductive field service tools.

•

HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide 2-1

Removal and Replacement Procedures

Symbols on Equipment

These symbols may be located on equipment in areas where hazardous conditions may exist.

Any product or assembly marked with these symbols indicates that the component exceeds the recommended weight for one individual to handle safely.

66 kg 160 lb

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.

Any surface or area of the equipment marked with these symbols indicates the presence of a hot surface or a hot component.

WARNING: To reduce the risk of injury from a hot component, allow the surface to cool before touching it.

Any surface or area of the equipment marked with these symbols indicates the presence of electrical shock hazards. The enclosed area contains no operator-serviceable parts.

WARNING: To reduce the risk of injury from electrical shock hazards, do not open this enclosure.

Any RJ-45 receptacle marked with these symbols indicates a network interface connection.

WARNING: To reduce the risk of electric shock, fire, or damage to the equipment, do not plug telephone or telecommunications connectors into this receptacle.

Rack Warnings and Cautions

WARNING: To reduce the risk of personal injury or damage to the equipment, adequately stabilize the rack before extending a component outside the rack. Extend only one component at a time. A rack may become unstable if more than one component is extended.

WARNING: To reduce the risk of personal injury or damage to the equipment:

• Extend the leveling jacks to the floor.

• Rest the full weight of the rack on the leveling jacks.

• Attach the stabilizers to the rack, if it is a single rack installation.

• Couple the racks together in multiple rack installations.

WARNING: When installing the server in a telco rack, adequately secure the rack frame to the building structure at the top and bottom.

2-2 HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide

WARNING: To reduce the risk of personal injury or damage to the equipment, use two or more people 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 moved on its casters. Handle the rack from both sides as it rolls down the ramp from the pallet. Do not stand in front of the rack.

CAUTION: Always begin by mounting the heaviest item on the bottom of the rack. Continue

to populate the rack from the bottom to the top.

Server Warnings and Cautions

WARNING: Do not exceed the level of repair specified in the procedures in the product documentation. All troubleshooting and repair procedures are detailed to allow only subassembly or module-level repair. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.

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.

WARNING: To reduce the risk of electric shock or damage to the equipment:

• Do not disable the AC 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 each power supply to disconnect power to the

equipment.

WARNING: Before lifting the server, remove all hot-plug power supplies and hard drives to reduce weight.

WARNING: The installation of internal options and routine maintenance and service of this product should be performed by individuals who are knowledgeable about the procedures, precautions, and hazards associated with equipment containing hazardous energy levels.

WARNING: Do not use conductive tools that could bridge live parts. Remove all watches, rings, or loose jewelry when working in hot-plug areas of an energized server.

WARNING: Do not replace non-hot-pluggable components while power is applied to the product. First, shut down the product and disconnect all AC power cords.

Removal and Replacement Procedures

HP ProLiant ML570 Generation 2 Server Maintenance and Service Guide 2-3

Removal and Replacement Procedures

WARNING: Be sure that the AC power supply branch circuit that provides power to the rack is not overloaded. Maintaining a low electrical current draw reduces the risk of personal injury, fire, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating. Consult the electrical authority having jurisdiction over your facility for wiring and installation requirements.

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: Do not operate the server for extended periods without the access panel. Operating the server without the access panel results in improper airflow and improper cooling that can lead to thermal damage.

CAUTION: Reinstall each hard drive into the specific slot from which it was removed. Mixing the hard drives adversely affects the system drive configuration.

Accessing Server Components

In order to access components in the server, any or all the following procedures may be required:

Extending the server from the rack

•

Opening the hot-plug door

•

Removing the front bezel door (tower model only)

•

Removing the rack bezel (rack model only)

•

Removing the access panel

•

Opening the system tray

•
