Appendix D: Troubleshooting
No power status light on user station
Verify that the power supply is plugged in correctly.
Ensure that the power cable from the Avocent-supplied power supply is securely plugged into 
the user station.
No video on monitor attached to LongView IP KVM user station
Verify that the monitor attached to the user station has power.
Ensure that the video cable from the monitor is securely plugged in to the correct connector on 
the user station.
Verify that the target computer is turned on.
Confirm that a network connection exists between the transmitter and user station.
Verify the address of the target transmitter configured in the user station is correct.
Confirm that the IP address used by the transmitter has not been assigned to a second device on 
the network.
Confirm that the IP address used by the user station has not been assigned to a second device 
on the network.
Verify that the transmitter is drawing sufficient power from the USB connections on the target 
computer and that it has booted correctly: 
If the green LED on the transmitter is on, the transmitter is drawing sufficient power.
If the transmitter cannot draw sufficient power from the target computer you will need to 
obtain an external power supply unit for the transmitter from Avocent. If connected 
through a USB hub, ensure that the hub can supply enough power.
NOTE: The LVIPHR-T and LVIPDH-T transmitters require an external power supply, which is shipped with those 
units. The LVIP-T and LVIPVG-T transmitters do not come with an external power supply, but you can obtain one 
from Avocent.
Verify that the correct video setting has been configured in the transmitter serial menu:
If the target computer provides DVI-only video, verify that the transmitter serial menu has 
been configured for DVI. Then restart the target computer.
If the target computer provides VGA-only video, verify that the transmitter serial menu 
has been configured for VGA. Then restart the target computer.
The transmitter has an internal fan. Verify that the fan is functioning.
Turn the LongView IP KVM user station on, then off again. An informational message should 
appear on the monitor for a brief moment. If the message does not appear, check the monitor 
by plugging the video cable from the monitor directly into the target computer to verify that the 
monitor is working and that the target computer is generating active video. If this is function-
