Appendix D: Troubleshooting

No power status light on receiver

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 receiver.

No video on monitor attached to receiver

Verify that the monitor attached to the receiver has power.

Ensure that the video cable from the monitor is securely plugged in to the correct connector on the receiver.

Verify that the remote workstation is turned on.

Confirm that a network connection exists between the transmitter and receiver.

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 receiver 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 remote workstation 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 remote workstation, 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.

Verify that the correct video setting has been configured in the transmitter serial menu:

If the remote workstation provides DVI-only video, verify that the transmitter serial menu has been configured for DVI. Then restart the remote workstation.

If the remote workstation provides VGA-only video, verify that the transmitter serial menu has been configured for VGA. Then restart the remote workstation.

The transmitter has an internal fan. Verify that the fan is functioning.

Cycle power to the receiver. 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 remote workstation to verify that the monitor is working and that the remote workstation is generating active video. If this is functioning, check that the dis- play settings for your remote workstation are set no higher than a resolution of 1280 x 1024 at 60 Hz refresh rate. If the monitor does not function correctly, replace it.

If the transmitter has been turned off and then turned on again (by unplugging the USB cables), ensure that all other cables are disconnected before reconnecting the transmitter. Ensure that you connect the USB cables first.
