Troubleshooting

Overview

Operation problems can be due to a variety of causes. The first step in solving
them is to make sure that all cables are securely attached and seated completely
in their sockets.
In addition, updating the product's firmware may solve problems that have
been discovered and resolved since the prior version was released. If your
product is not running the latest firmware version, we strongly recommend that
you upgrade. See The Firmware Upgrade Utility, page 189, for upgrade
details.
Problem
There are ghost images on
the external monitor.
The distance between the external console and the
CL5708I / CL5716I is too great. The maximum VGA
cable distance should not exceed 20m and, in some
cases, may need to be shorter. Replace the VGA cable
with one of an appropriately short length.
