AMX Switch Series Installer/User Guide
Appendix E: Troubleshooting
One or two colors are missing on a server or a user station
•
Check the VGA connection between the user station and the monitor.
•
Check the VGA connection between the IQ module and the server.
•
Connect the monitor directly to a server to determine if the video card is causing the fault.
•
If the video quality is poor on all servers from one user station, replace the UTP cable
connecting the user station and the switch.
•
Swap ports on the switch to determine if there is a port failure.
•
To determine if there is hardware failure, complete one of the following steps: 1) If the colors
are missing on a server, swap the IQ module; or 2) If the colors are missing on a user station,
swap the user station.
Video does not display after connection is made to a server
•
Make sure that the monitor is compatible with resolution settings on the server.
•
The server may be in sleep mode. Use the keyboard or mouse to restore normal
operating mode.
Video quality is poor; colors are missing or too bright
•
Make sure the monitor is connected to the user station using a UTP cable and that the VGA
connector is inserted correctly. Other cables, such as STP cables, may cause poor video quality
when used at distances over 400 feet.
•
If poor video quality is random, test the cables between tiers of AMX switches.
Switches cannot be made;
Connection timeout
error message displays
•
If any of the green LEDs on the front of the AMX switch are flashing, make sure the IQ
modules are connected to the server ports and that the user stations are connected to the user
ports. See Figure 2.6 on page 14 for more information about the location of each ports.
•
Make sure that cables between cascaded AMX switches are connected to the correct ports. In a
cascaded switching system, UTP cable is connected from the server ports on the primary
switch to the user ports on the secondary switches. This process may be repeated to add a
tertiary level of switches. Make sure that no switch has a user port connected back into one of
it's own server ports. See Installing a Cascaded AMX Switching System on page 21 for
more information.
•
If any of the green LEDs are still flashing, use the AMWorks software to Flash upgrade the
corresponding IQ module. See the AMWorks software online help for more information.
•
If the Connection timeout error message still displays, power cycle the AMX switch and
start again.
