Appendix D: Troubleshooting

No power status light on ECMS 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 ECMS user station.

No video on monitor attached to ECMS user station

• Verify that the monitor attached to the ECMS user station has power.

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

the ECMS user station.

• Verify that the remote computer is turned on.

• Confirm that a network connection exists between the transmitter and ECMS user station.

• Verify that the address of the target transmitter that is 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 ECMS 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 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.

• Turn the ECMS 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 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 display 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.
