About This Guide

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

StorageWorks Modular Smart Array 500 system.

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.

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 system.

CAUTION: The equipment 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

To service the MSA500 system, you may need the following tools:

• Flat-blade screwdriver

• From the SmartStart CD:

— Advanced Diagnostics Utility (ADU)

— ROM Update Utility

Safety Considerations

Before performing service procedures, review all the safety information.

Preventing Electrostatic Discharge

To prevent damaging the system, be aware of the precautions you need to follow when

setting up the system or handling parts. A discharge of static electricity from a finger or other

conductor may damage system boards or other static-sensitive devices. This type of damage

may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free

workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

Removal and Replacement Procedures

HP CONFIDENTIAL Codename: Aurora Part Number: 251850-004 Last Saved On: 9/19/03 10:57 AM

Rack Warnings and Cautions

WARNING: Because the rack allows stacking of computer components on a vertical

rather than horizontal plane, be sure that precautions have been taken to provide for

rack stability and safety. It is important to follow these precautions providing for rack

stability and safety, and to protect both personnel and property. Heed all cautions and

warnings throughout the installation instructions provided with the device.

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

• Observe local occupational safety requirements and guidelines for heavy

equipment handling.

• Obtain adequate assistance to lift and stabilize the product during installation or

removal.

• Always load the heaviest item first, and load the rack from the bottom up. This

makes the rack bottom-heavy and helps prevent the rack from becoming unstable.

• Extend the leveling jacks to the floor.

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

• Attach the stabilizing feet to the rack if it is a single-rack installation.

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

• Fully extend the bottom stabilizers on the equipment. Be sure that the equipment is

properly supported/braced when installing options and boards.

• Be sure that the rack is adequately stabilized 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 for any reason.

• Do not attempt to move a fully loaded equipment rack. Remove equipment from the

rack before moving the rack.

• 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 2.1m (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 it from the sides. Stabilize the device by keeping

the unit on the rails.

Device Warnings and Cautions

Before installing a system, be sure that you understand the following warnings and cautions.

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

all warnings and cautions throughout this chapter.

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.
