Communication
fails
(continued).
Communications cabling is
connected incorrectly.
Ensure that all communications cables are routed
correctly and connected properly. If the
connections are secure, determine whether the
cable is defective by doing the following:
• Check to see if the green communications
LED inside the InTouch is lit. Use the
security wrench to unlock and open the cover
of the InTouch.
• Check to see if the green link light on the hub
to which the InTouch is connected is lit.
If both lights are lit, the cable is not defective.
The issue may be the network configuration. If
both lights are not lit, the cable may be defective.
Consult with your system administrator to
resolve the issue.
