equipment. Improper repairs can create conditions that are hazardous.

Symbols in Text

These symbols may be found in the text of this guide. They have the following meanings.

WARNING: Text set off in this manner indicates that failure to follow directions in the

warning could result in bodily harm or loss of life.

CAUTION: Text set off in this manner indicates that failure to follow directions could result in

damage to equipment or loss of information.

IMPORTANT: Text set off in this manner presents clarifying information or specific instructions.

NOTE: Text set off in this manner presents commentary, sidelights, or interesting points of information.

Important Safety Information

Before installing this product, read the Important Safety Information document provided.

Compaq Technician Notes

WARNING: Only authorized technicians trained by Compaq 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.

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

Compaq ProLiant ML350 Generation 2 server. Run the diagnostics program to be sure that

all components operate properly.

To service the server, you may need a Torx T-15 screwdriver.

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.

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.

COMPAQ CONFIDENTIAL Codename: Forge Part Number: 236634-002 Last Saved On: 5/14/02 12:00 PM

Preparation Procedures

WARNING: Only authorized technicians trained by Compaq 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, and drive

cages.

Powering Down the Server

System power in the server does not completely power down when the front panel power

button is pressed. The button toggles between on and standby, rather than on and off. 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, you must

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.

To power down the server:

1. Press the power button to toggle to standby. This places the server in standby mode,

thereby 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.
