Safety Precautions
To avoid potential video and/or keyboard problems when using Avocent 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 Avocent-supplied cable to connect computers and KVM switches.
Avocent 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:
• Do not use a 2-wire extension cord in any Avocent 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 OutLook unit off the supply.
NOTE: The AC inlet is the main disconnect.
