Table C.1: Troubleshooting
No power status light on transmitter or receiver
Verify that the green LED on the separate Avocent-supplied power supply is illuminated, indicating that the
power supply is plugged in correctly.
Ensure that the power cable from the Avocent-supplied power supply is securely plugged into the LongView
Wireless transmitter or LongView Wireless receiver.
No video on monitor attached to transmitter
Verify that the monitor has power.
Ensure that the video cable from the monitor is securely plugged in to the correct connector on the LongView
Wireless transmitter.
Verify that the server is powered.
As a last check, plug the video cable from the monitor directly into the server to verify that the monitor is
working and that the server is generating active video. If this is functioning, check that the display settings for
your server are set no higher than a resolution of 1024 x 768 at 60 Hz refresh rate. If the monitor does not
function correctly, replace it.
No mouse and/or keyboard operation from peripherals attached to transmitter
Verify that the mouse and keyboard are connected to the correct PS/2 ports on the server. Match the connector
color codes (green is mouse and purple is keyboard).
If the LongView Wireless transmitter was powered up after the server, turn off the server and transmitter.
Power up the LongView Wireless transmitter, wait for the middle LED to illuminate, then power up
the server.
Retest the mouse and keyboard by connecting them directly to the server and rebooting the server. If one does
not function correctly, replace the non-functioning peripheral.
No video on monitor attached to receiver
Verify that the monitor attached to the LongView Wireless receiver has power.
Ensure that the video cable from the monitor is securely plugged in to the correct connector on the LongView
Wireless receiver.
Ensure that the video cable from the LongView Wireless transmitter is securely plugged in to the correct
connector on the server.
Verify that the server is powered.
Cycle power to the LongView Wireless 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 server to verify that the monitor is working and that the server is generating active video. If this
is functioning, check that the display settings for your server are set no higher than a resolution of 1024 x 768
at 60Hz refresh rate. If the monitor does not function correctly, replace it.
