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.

Symbols on equipment

The following symbols may be placed on equipment to indicate the presence of potentially hazardous

conditions.

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.

Removal and replacement procedures 15

25-41 kg

55-90 lbs

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.

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.

Rack warnings

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 attached 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.

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

a rack:

• At least two people are needed to safely unload the rack from the pallet. An empty

42U rack can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft)

tall, and may become unstable when being moved on its casters.

• Never stand in front of the rack when it is rolling down the ramp from the pallet.

Always handle the rack from both sides.

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: When installing a server in a telco rack, be sure that the rack frame is

adequately secured to the top and bottom of the building structure.

Preparation procedures

To access some components and perform certain service procedures, you must perform one or more of the

following procedures:

• Extend the server from the rack ("Extending the server from the rack" on page 16).

If you are performing service procedures in an HP, Compaq branded, telco, or third-party rack

cabinet, you can use the locking feature of the rack rails to support the server and gain access to

internal components.

For more information about telco rack solutions, refer to the RackSolutions.com website

• Power down the server (on page 16).
