AMX Switch Series Installer/User Guide
server within the system. The connection between the AMX switching system and these modules is
through industry standard UTP cabling.
UTP cables
The AMX switching system uses video technologies that compensate for the losses that occur in all
UTP cables. These technologies make the AMX switch compatible with most UTP cable types and
support AMX switch use in environments where there are combinations of UTP cable types and
patch panels. The AMX switch will function correctly with any combination of CAT 5, CAT 5e
and CAT 6 cables.
NOTE: Throughout this manual, the generic term UTP refers to any CAT cable used by the AMX switching system.
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 server and monitor. When using a backup
Uninterruptible Power Supply (UPS), power the server, the monitor and the AMX switch off
the supply.
NOTE: The AC inlet is the main disconnect.
DC installation safety considerations
As a safety precaution, install this product in an area with limited or controlled access. A readily
accessible disconnect device that is suitably approved and rated shall be incorporated in the field
wiring. Connect field wiring from earth ground to the screw terminal marked with the ground
symbol. Terminals will accommodate wiring from 26 to 12 AWG (up to 2.5 mm
section). Strip each wire, insert it in the square opening in the terminal block and tighten the screw
above it to a maximum of 70 ounce-inches (0.5 Nm) using either a flat or Phillips-head screwdriver.
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.
•
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.
