Safety Precautions
To avoid potential video or keyboard problems when using Cybex products:
-
If the building has 3-phase AC power, ensure that the computer and monitor are on the same phase. For best results, they should
be on the same circuit.
-
Use only Cybex-supplied cable. Cybex warranties do not apply to damage resulting from user-supplied cable.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe the following precautions:
-
Use equipment only as intended.
-
Do not use equipment outside or in wet rooms.
-
Avoid exposure to direct sunlight.
-
Keep the equipment away from sources of vibration or physical shock.
-
Isolate equipment from strong electromagnetic fields produced by electrical devices.
-
Do not cover the ventilation openings.
-
Never install equipment that appears damaged. If the equipment is malfunctioning, contact the supplier. Never open the
equipment yourself. There are no serviceable parts inside.
-
With the exception of adding or removing original Cybex manufactured modules in accordance with written Cybex instructions, the
equipment and all attached computers should be powered down before servicing. Always disconnect the power cord from the unit.
Note: The AC inlet is the main disconnect. Caution: XP4400 may have two power cords. To remove power completely, both line
cords must be disconnected.
-
XP4400 power supplies are hot swappable; they can be removed while XP4400 is receiving power from the supply in the other
slot. But the supply must not be connected to AC power before being installed or removed.
-
The equipment is safety class I (as defined by IEC950/EN60950) and has protective earthing terminals. There must be an
uninterruptible safety earth ground from the main power source to the equipment's input wiring terminals, power cord, or supplied
power cord set. Whenever it is likely the protection has been impaired, disconnect the power cord until the ground has been
restored.
-
Do not use a 2-wire extension cord in any Cybex product configuration.
-
Use only with grounded outlets at both the computer and monitor.
-
Test AC outlets at computer and monitor for proper polarity and grounding.
-
When using a backup power supply (UPS), power the computer, the monitor and the KVM equipment off the supply.
-
The safety status of all interconnection points, that are for connection of other equipment is SELV (safety extra-low voltage, as
defined by IEC950/EN60950). SELV circuits should only be connected to other SELV circuits.
Rack Mount Safety Considerations
-
Elevated Ambient Temperature: If installed in a closed rack assembly, the operation temperature of the rack environment may be
greater than room ambient. Use care not to exceed the rated maximum ambient temperature of the unit.
-
Ventilation: Make sure the air flow around the sides and top of the equipment is not restricted. The distance between ventilation
openings and other equipment should be at least +" (2cm). Ensure that for any slot into which no module is installed, the cover
plate is installed to cover the slot. A cover plate is required for safe operation, and to ensure proper cooling. Avoid placing the
equipment in an overly congested rack because the heated exhaust air from other devices can enter the inlet air vents and cause
an overtemperature condition inside the equipment.
-
Clearance: Allow at least 19" (48cm) of clearance at the back of the rack for maintenance.
-
Mechanical Loading: The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling over.
Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest device at the bottom and
progressively lighter devices installed above. The mechanical load of the rack or cabinet must not exceed the maximum load
indicated. Be sure to use all of the screws provided to secure the equipment to the rack posts.
-
Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that
overloading of circuits might have on overcurrent protection and supply wiring. To determine the possibility of overloading the
supply circuits, add together the ampere ratings of all devices installed on the same circuit and compare the total with the rating
limit for the circuit. Consider equipment nameplate ratings for maximum current.
-
Reliable Earthing: Reliable earthing of rack mounted equipment should be maintained. Make sure that the power source circuits
are properly grounded, then use the power cord supplied with the equipment to connect it to the power source. If your installation
requires a different power cord than the one supplied with the equipment, be sure to use a power cord displaying the mark of the
safety agency that defines the regulations for power cords in your country. If the equipment is mounted in racks, grounding by
power cord with earth conductor cannot be replaced by grounding the rack. Additional earthing of the rack or cabinet has no
influence on the safety of the whole system but can be done in parallel.
-
Lifting Guidelines: A fully configured XP4400 weighs approximately 77lb (35kg); it is not intended to be moved frequently. Before
you install the equipment, ensure that your site is properly prepared so you can avoid having to move the XP4400 later to
accommodate power sources and connections. Whenever you lift any heavy assembly, follow these guidelines:
-
Have a second person available to help lift the assembly; avoid lifting the assembly alone.
-
Ensure that your footing is solid; balance the weight of the object between your feet.
-
Lift the assembly slowly; never move suddenly or twist your body as you lift.
-
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the assembly, bend at the knees,
not at the waist, to reduce the strain on your lower back muscles.
-
Always disconnect all external cables before lifting or moving the XP4400. Caution: To prevent damage, never attempt to lift
or tilt the XP4400 using the handles on the fan modules or on the power supplies. These handles are not designed to support
the weight of the XP4400.
-
Nameplate Rating: The equipment is rated 100-240V~, 50/60Hz. All components except the XP4400 are rated 1.6A (single
component power supply) or 3.2A (dual component power supply). XP4400 is rated 7A (single or dual power supply).
