Troubleshooting the HAL Hardware
Problem
Possible Causes
Suggested Action
Power light doesn’t come
on when the device is
plugged in.
Power outlet or power strip
isn’t working.
Try a different outlet or power strip.
HAL power cord is mal-
functioning.
Replace the HAL power cord.
Ethernet Link LED indi-
cators do not come on
after plugging the HAL
into a network switch or
connecting it directly to a
computer.
HAL and/or network switch
isn’t powered on.
Power on both devices.
Patch cable or crossover
cable is broken.
Try a different cable.
The port on the network
switch isn’t working.
Try plugging the cable into a different
port on the network switch.
Displayed on the rear panel of the HAL are four status indicators for each connected RAD. If the
HAL is communicating properly with a RAD, all four status indicators (Audio Rx, Audio Tx,
Comm, and Power) should be on. The following table details possible causes and solutions for sit-
uations in which one or more of these indicators are off.
NOTE
:
It is best to check these indicators in the following order: Power, Comm, Audio Tx,
and Audio Rx. If the power isn’t working, nothing else will work. If the data com-
munications (Comm) isn’t working, Audio Tx will not work. If Audio Tx isn’t working,
Audio Rx will not work.
