Safety Guidelines

Before you remove a server cover, observe these safety guidelines:

• Only technically qualified personnel should integrate the server.

• Turn off all peripheral devices connected to the server.

• Turn off the server using the push-button on/off power switch on the front panel of the server,

and unplug the AC power cord from each power supply or wall outlet.

• Label and disconnect all peripheral cables attached to the I/O panel on the back of the server.

• Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap

attached to chassis ground of the server—any unpainted metal surface—when handling components.

Server Precautions

WARNINGS

SERVER POWER ON/OFF: The push-button on/off power switch on the front panel of the server does not turn off the AC power. To remove AC power from the server, you must unplug each AC power cord from each power supply or wall outlet.

HAZARDOUS CONDITIONS—POWER SUPPLY AND POWER SHARE

BACKPLANE: Hazardous voltage, current, and energy levels are present

inside the power supply and the power share backplane enclosures. There are no user-serviceable parts inside them; servicing should only be done by technically qualified personnel.

HAZARDOUS CONDITIONS—DEVICES AND CABLES: Hazardous electrical conditions may be present on power, telephone, and communication cables. Turn off the server and disconnect telecommunications systems, networks, modems, and each power cord attached to the server before opening it. Otherwise, personal injury or equipment damage can result.

AVOID INJURY: To avoid personal injury when unpacking the server, use only a mechanical assist unit to lift it off the shipping pallet. The minimum server configuration weighs 38 kg (85 lbs); the maximum weighs 45 kg (100 lbs).

Do not attempt to lift or move the server by the handles on the power supplies.

Use only a hand-truck or other mechanical assist unit to move the server from one location to another.

CAUTIONS

ELECTROSTATIC DISCHARGE (ESD) AND ESD PROTECTION: ESD can damage disk drives, add-in boards, and other components. This server can withstand normal levels of environmental ESD while hot-swapping SCSI hard disk drives. However, we recommend doing all procedures in this manual only at an ESD-protected workstation. If one is not available, you can provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground of the server—any unpainted metal surface—when handling components.

HANDLING BOARDS AND MODULES: Boards and modules can be extremely sensitive to ESD and always require careful handling. After removing a board or module from its protective wrapper or from the server, place it component-side up on a nonconductive, static-free surface. If you place the baseboard on a conductive surface, the battery leads can short out. If they do, this will result in a loss of CMOS data and will drain the battery. Do not slide a board or module over any surface.

SERVER COOLING AND AIRFLOW: Operating the server with the covers removed can damage the server components. For proper cooling and airflow, always replace the covers before turning on the server.

Equipment Rack Precautions

WARNINGS

ANCHOR THE EQUIPMENT RACK: The equipment rack must be anchored to an unmovable support to prevent it from falling over when one or more servers are extended in front of it on slide assemblies. The anchors must be able to withstand a force of up to 113 kg (250 lbs). You must also consider the weight of any other device installed in the rack.

MAIN AC POWER DISCONNECT: You are responsible for installing an AC power disconnect for the entire rack unit. This main disconnect must be readily accessible, and it must be labeled as controlling power to the entire unit, not just to the server(s).

GROUNDING THE RACK INSTALLATION: To avoid the potential for an electrical shock hazard, you must include a third wire safety grounding conductor with the rack installation. If server power cords are plugged into AC outlets that are part of the rack, then you must provide proper grounding for the rack itself. If server power cords are plugged into wall AC outlets, the safety grounding conductor in each power cord provides proper grounding only for the server. You must provide additional, proper grounding for the rack and other devices installed in it.

Overcurrent protection: The server is designed for an AC line voltage source with up to 20 amperes of overcurrent protection. If the power system for the equipment rack is installed on a branch circuit with more than 20 amperes of protection, you must provide supplemental protection for the server. If more than one server is installed in the rack, the power source for each server must be from a separate branch circuit. The overall current rating of a server configured with three power supplies is under 12 amperes.

CAUTIONS

Temperature: The operating temperature of the server, when installed in an equipment rack, must not go below 5 °C (41 °F) or rise above 35 °C (95 °F). Extreme fluctuations in temperature can cause a variety of problems in your server.

Ventilation: The equipment rack must provide sufficient airflow to the front of the server to maintain proper cooling. It must also include ventilation sufficient to exhaust a maximum of 4,100 Btu's per hour for the server. The rack selected and the ventilation provided must be suitable to the environment in which the server will be used.
