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
, page 57, for upgrade details.
General
Problem
Solution
Keyboard and/or mouse do
not work after computer
boots up.
For computers with PS/2 connectors, if you are using 2L-
520xP cables, make sure that all the connectors
(keyboard, video, and mouse) are plugged into their ports
on the computer before starting the computer. Plugging
the cables in after the computer has booted will not
resolve the problem.
When I emulate the Sun
keyboard, I can’t go into OK
Mode ([Stop] [A]).
To go into OK Mode, use the following key sequence:
1. Press and release [Ctrl].
2. Press and hold [T].
3. Press and hold [A].
4. Release [T] and [A] together.
There are ghost images on
the external monitor.
The distance between the external console and the
KL3116 / KL3116T is too great. The maximum VGA cable
distance should not exceed 20 m and, in some cases,
may need to be shorter. Replace the VGA cable with one
of an appropriately short length.
