•
Follow installation instructions carefully.
•
Do not attempt to service the equipment yourself.
•
You should operate this equipment from the type of external power source indicated on
the electrical ratings label.
•
Always leave at least 4 inches (10.2cm) of physical clearance on all vented sides of the
M-500 appliance. This permits the airflow required for proper ventilation.
•
Avoid placing equipment close together such that it is subject to re-circulated (pre-heated)
air.
•
Ensure that all cables connected to the M-500 appliance are not under stress or high
tension 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 M-500 appliance.
•
To protect the M-500 appliance from fluctuations in electrical power, use a surge
suppressor, line conditioner or uninterruptible power supply (UPS).
•
Slide Rail Caution—Slide rail mounted equipment is not to be used as a shelf or a work
space.
•
Elevated Operating Ambient—If the M-500 appliance 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 “Environmental Specifications” on page 24.
•
Reduced Air Flow—Installation of the M-500 appliance in a rack should be such that the
amount of air flow required for safe operation is not compromised.
•
Mechanical Loading—Mounting of the M-500 appliance 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—Devices mounted in racks should be grounded properly. If using
power strips to connect the M-500 appliance to the supply circuit, make certain that the
power strips are also grounded properly.
•
Compatible Rack Systems—It is your responsibility to ensure that the rack and the
provided rail system are compatible with each other before installing the M-500
appliance.
•
Rack Stabilizers—Install the front and side stabilizers on the rack prior to installing
equipment. Failure to install stabilizers may cause a rack to tip over.
CAUTION
Please observe the following additional precautions for rack-mounted systems:
