8 Local Console Manager Installation and User’s Guide
• Be sure that the monitor and attached devices are electrically rated to operate with the power
that is available in the current location.
• Use only power cables that are provided with the appliance.
• To help prevent electric shock, connect the appliance and peripheral power cables into properly
grounded electrical outlets. These cables are equipped with three-prong connectors to help
ensure proper grounding. Do not use adapter connectors or remove the grounding prong from
a cable.
• Observe extension cable and power strip ratings. Make sure that the total ampere rating of all
products that are connected to the power strip does not exceed 80 percent of the ampere ratings
limit for the power strip.
• To help protect the appliance from sudden, transient increases and decreases in electrical
power, use a surge suppressor, line conditioner, or uninterruptible power supply.
• Carefully position appliance cables and power cables. Route cables so that they cannot be
stepped on or tripped over. Be sure that nothing rests on any cables.
• Do not modify power cables or connectors. Consult a licensed electrician or the power com-
pany for site modifications. Always follow the local and national wiring rules.
Rack mounting the appliance
Before installing the appliance and other components in the rack (if not already installed), stabilize
the rack in a permanent location. Install the equipment starting at the bottom of the rack, then work
to the top. Avoid uneven loading or overloading of racks.
General guidelines
• Refer to the rack installation documentation the accompanied the rack for specific caution
statements and procedures.
• Elevated ambient temperature: In a closed rack assembly, the operation temperature of the rack
environment can be greater than room ambient. Use care not to exceed the rated maximum
ambient temperature of the unit.
• Reduced air flow: Carefully install the equipment in a rack so that an adequate amount of
airflow is maintained for safe operation of the equipment.
• Mechanical loading: Avoid a potentially hazardous condition caused by uneven mechanical loading
by carefully mounting the equipment in the rack.
• Circuit overloading: Consider the connection of the equipment to the supply circuit and the
effect that overloading of circuits might have on overcurrent protection and supply wiring.
Observe equipment nameplate ratings for maximum current.
• Reliable earthing: Maintain reliable earthing of rack-mounted equipment. Pay particular
attention to supply connections other than direct connections to the branch circuit (for
example, use of power strips).
