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 server 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 extension cord in any Avocent product configuration.
• Test AC outlets at the server and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the workstation and monitor. When using a backup
Uninterruptible Power Supply (UPS), power both the workstation and the transmitter off the
same supply.
NOTE: The AC inlet is the main disconnect.
