About This Guide

This maintenance and service guide can be used for reference when servicing HP

ProLiant ML350 Generation 3 servers.

WARNING: To reduce the risk of personal injury from electric shock and hazardous energy levels, only authorized service technicians should attempt to repair this equipment. Improper repairs can create conditions that are hazardous.

Audience Assumptions

This guide is for service technicians. HP assumes you are qualified in the servicing of computer equipment and trained in recognizing hazard in products with hazardous energy levels and are familiar with weight and stability precautions for rack installations.

Technician Notes

WARNING: Only authorized technicians trained by HP should attempt to repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module-level repair. Because of the complexity of the individual boards and subassemblies, no one should 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 electric shock and hazardous energy levels, do not exceed the level of repairs specified in these procedures. 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 conditions that are hazardous.

About This Guide

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

•Disconnect power from the system by unplugging all power cords from the power supplies.

•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.

CAUTION: To properly ventilate the system, you must provide at least 7.6 cm (3.0 in.) of clearance at the front and back of the server.

CAUTION: The computer is designed to be electrically grounded (earthed). To ensure proper operation, plug the AC power cord into a properly grounded AC outlet only.

NOTE: Any indications of component replacement or printed wiring board modifications may void any warranty.

Removal and Replacement Procedures

This chapter provides subassembly/module-level removal and replacement procedures for the HP ProLiant ML350 Generation 3 server. After completing any removal or replacement procedure, run the diagnostics program to verify that all components operate properly.

To service the server, a T-15 Torx screwdriver may be needed.

Removal and Replacement Procedures

Electrostatic Discharge Information

An electrostatic discharge (ESD) can damage static-sensitive devices or microcircuitry. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage, observe the following precautions:

•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.

•Make sure that you are always properly grounded (earthed) when touching a static-sensitive component or assembly.

•Avoid touching pins, leads, or circuitry.

•Always place drives with the Printed Circuit Board (PCB) assembly-side down.

•Use conductive field service tools.

Removal and Replacement Procedures

Symbols on Equipment

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

WARNING: This symbol, in conjunction with any of the following symbols, indicates the presence of a potential hazard. The potential for injury exists if warnings are not observed. Consult your documentation for specific details.

This symbol indicates the presence of hazardous energy circuits or electric shock hazards. Refer all servicing to qualified personnel.

WARNING: To reduce the risk of injury from electric shock hazards, do not open this enclosure. Refer all maintenance, upgrades, and servicing to qualified personnel.

This symbol indicates the presence of electric shock hazards. The area contains no user or field serviceable parts. Do not open for any reason.

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

This symbol on an RJ-45 receptacle 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.

This symbol indicates the presence of a hot surface or hot component. If this surface is contacted, the potential for injury exists.

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

These symbols, on power supplies or systems, indicate that the equipment is supplied by multiple sources of power.

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

Weight in kg Weight in lb

This symbol indicates that the component exceeds the recommended weight for one individual to handle safely.

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.

Removal and Replacement Procedures

Preparation Procedures

WARNING: Only authorized technicians trained by HP should attempt to repair this equipment. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.

CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that you are properly grounded (earthed) before beginning any installation procedure. Refer to “Electrostatic Discharge Information” earlier in this chapter for more information.

Before removing any serviceable parts, determine whether the part is hot-pluggable or non-hot-pluggable.

Non-Hot-Pluggable Device

If the device is non-hot-pluggable, the server must be powered down. Non-hot-pluggable devices in the server include the processor, all boards, memory modules, fans, PCI option cards and drive cages.

Powering Down the Server

The server does not completely power down when the front panel power button is pressed. The button toggles between On and Standby. The standby position removes power from most electronics and the drives, but some internal circuitry remains active. To completely remove all power from the system, disconnect all power cords from the server.

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

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

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 must always be operated with system unit covers on. Proper cooling is not achieved when the system unit covers are removed.

2-4	HP ProLiant ML350 Generation 3 Server Maintenance and Service Guide

Removal and Replacement Procedures

To power down the server:

1.Press the power button to toggle to Standby. This places the server in standby mode, disabling the main power supply output and providing auxiliary power to the server. Standby does not completely disable or remove power from the system.

2.Be sure that the system LED closest to the right on the front panel is amber and that the fan noise has stopped.

3.Disconnect the AC power cord from the AC outlet, and then from the server.

4.Disconnect all external peripheral devices from the server.

Rack Stability Warning

For stability and safety, properly positioning the server is critical.

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 stabilizing feet are connected to the rack if it is a single-rack installation.

•The racks are coupled together in multiple-rack installations.

•Only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason.
