2.2 Safety Precautions
To avoid potential video and/or keyboard problems when using these 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 BLACK BOX-supplied cable to connect computers and KVM switches.
To avoid potentially fatal shock hazard and possible damage to equipment, please
observe the following precautions:
•
Do not use a 2-wire extension cord in any BLACK BOX product configuration.
• Test AC outlets at the computer and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the computer and monitor. When using
a backup power supply (UPS), power the computer, the monitor and the appli-
ance off the supply.
NOTE:
The AC inlet is the main disconnect.
Rackmount safety considerations
• Elevated Ambient Temperature: If the equipment is 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 equipment.
• Reduced Air Flow: Installation of the equipment in a rack should be such that the
amount of airflow required for safe operation of the equipment is not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
• 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. Consider equipment name-
plate ratings for maximum current.
• Reliable Earthing: Reliable earthing of rackmounted equipment should be
maintained. Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).
