Maintenance Port Precautions

The serial console is only used for periodic maintenance and not to be used under normal operation.

General Safety

CAUTION Please note the following:

1	The server will not be used in a home, school or other public area where the general population would have access to it.

2	The manufacturer specifies that the thumbscrew normally should be tightened with a screwdriver. Use of a thumbscrew is not considered to compromise the basic principles of safety associated with the standard.

WARNING  To prevent potential for personal injury, property damage or death, please observe the following instructions:

•	Do not use damaged equipment, including exposed, frayed or damaged power cords. Use only the approved power cable that is rated for the equipment. The voltage and current rating of the cable should be greater than the ratings marked on the equipment.

•	Plug the power cables into properly grounded electrical outlets

•	Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs.

•	Observe extension cable and power strip ratings to ensure that the total ampere rating of all equipment plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or power strip.

•	When connecting or disconnecting power to hot-swappable power supplies, observe the following precautions:

•	Install the power supply before connecting the power cable to it.

•	Unplug the power cable before removing a power supply.

•	To disconnect power from the server, disconnect all power cables from all power supplies. (If you only disconnect one hot-swappable power supply, the system will automatically switch to a redundant one.)

•	The power supplies in the server may produce high voltages and potential energy hazards. By opening the cover of the server you may be exposed to a risk of electric shock. The components inside the server housing should only be serviced by a trained service technician.

•	Inside the housing, the power supply may have more than one power supply cable. To reduce the risk of electric shock, a trained service technician may need to disconnect all power supply cables before servicing the system.

•	The server should not be operated with the cover removed.

•	Components inside the server housing may become extremely hot during normal operations. These components include the memory and CPU modules. Allow sufficient time for components to cool before handling.

•	The server should not be operated in environments that can get wet. Protect the server at all times from liquid intrusion.

•	If your server gets wet, turn off the AC power at the circuit breaker before attempting to remove the power cables from the electrical outlet. Then disconnect power to the equipment and to any attached devices.

•	Avoid obstructing the air vents on the server or pushing objects into the openings. This could lead to fire or electric shock.

CAUTION  To prevent hardware damage or loss of data, observe the following precautions:

•	Follow installation instructions carefully.

•	Do not attempt to service the equipment yourself. The server should be serviced by a trained service technician.

•	You should operate this equipment from the type of external power source indicated on the electrical ratings label.

•	Wait 30 seconds after turning off the equipment before removing a component from the system or disconnecting a peripheral device from the server.

•	Always leave at least 4 inches (10.2cm) of physical clearance on all vented sides of the server. This permits the airflow required for proper ventilation.

•	Avoid placing equipment too close together such that it is subject to re-circulated (pre-heated) air. Avoid placing equipment too close to an server or exhaust vent.

•	Ensure that cables are connected to the server without stress and that nothing rests on the cables.

•	If the equipment is located in a rack, move it with caution. Ensure that all casters and/or stabilizers are firmly connected. While moving the equipment, avoid uneven surfaces and sudden stops.

•	Do not place other equipment, monitors, or other devices on top of the server.

•	To protect the server from fluctuations in electrical power, use a surge suppressor, line conditioner or uninterruptible power supply (UPS).

WARNING  BATTERY WARNING: Installing an incompatible battery on the server board may increase the risk of fire or explosion. Observe the following precautions:

•	The battery should only be replaced with a battery that is the same or equivalent as the factory installed battery.

•	Do not attempt to open or service the battery. Do not dispose of the battery in a fire or with household waste. Contact the local waste disposal agency for the location of the nearest battery deposit site.

CAUTION  Please observe the following additional precautions for rack-mounted systems:

•	Slide/rail mounted equipment is not to be used as a shelf or a work space.

•

Elevated Operating Ambient – If the server is installed in a closed or multi-unit rack assembly, the operating ambient temperature in the rack environment may be greater than the room ambient temperature. Therefore, consideration should be given to the maximum operating temperature specified in the environmental specifications.

•	Reduced Air Flow – Installation of the server in a rack should be such that the amount of air flow required for safe operation is not compromised.

•	Mechanical Loading – Mounting of the server in the rack should not create a hazardous condition from uneven mechanical loading.

•	Circuit Overloading – Connection of the equipment to the supply circuit should not create an overloaded situation. Pay close attention to equipment nameplate ratings.

•	Reliable Grounding – Appliances mounted in racks should be grounded properly. If using power strips to connect the server to the supply circuit, make certain that the power strips are also grounded properly.

•	It is your responsibility to ensure that the rack and the provided rail system are compatible with each other before installing the server.

•	Install the front and side stabilizers prior to installing equipment in a rack. Failure to install stabilizers may cause a rack to tip over.

•	Load racks from the bottom up, loading the heaviest items near the bottom of the rack.

•	Do not stand or step on components in the rack.

•	Do not use slide-rail-mounted equipment as a shelf or workspace. Do not add weight to the top of the server.

WARNING  Grounding Instructions for Qualified Electricians Only:

•	Grounding techniques may vary. However, a positive connection to a safety (earth) ground is required.

•	Make the ground connection first and disconnect it last to prevent hazards.

•	Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor.

•	If the system is installed in a rack, ensure that the system chassis is securely grounded to the rack cabinet frame. Do not connect power to the system until grounding cables are connected.
