3.3 Safety Precautions
To avoid potential video and/or keyboard problems when using Black Box
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.
To avoid potentially fatal shock hazard and possible damage to equipment,
please observe the following precautions:
• Do not use a 2-wire power cord in any Avocent product configuration.
• Test AC outlets at the target device and monitor for proper polarity and
grounding.
• Use only with grounded outlets at both the target device and monitor. When
using a backup Uninterruptible Power Supply (UPS), power the target device, the
monitor and the switch from the UPS.
NOTE: The AC inlet is the main power disconnect.
Rack mount safety considerations
Elevated Ambient Temperature: If installed in a closed rack assembly, the operating
temperature of the rack environment may be greater than room ambient. Use care not to
exceed the rated maximum ambient temperature of the switch.
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 nameplate ratings for maximum
current. 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 nameplate ratings for maximum current.
Reliable Earthing: Reliable earthing of rack mounted equipment should be maintained.
Pay particular attention to supply connections other than direct connections to the branch
circuit (for example, use of power strips). Reliable earthing of equipment should be
maintained. Pay particular attention to supply connections other than direct connections to
the branch circuit (for example, use of power strips).
3.4 Connecting the appliance hardware
To connect and turn on the appliance, complete the following steps:
1. Turn off the target devices that are part of the switching system. Connect one end of
the power cord to the rear of the appliance and connect the other end to an AC power
source.
2. Connect a VGA monitor and either PS/2 or USB keyboard and mouse cables into the
labeled appliance ports. You must install both a keyboard and mouse on the local
