Schneider Electric AP5717F User Manual

There are ghost images on the external monitor

The distance between the external console and the Rack LCD 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.

Some characters entered from the keyboard do not 
display correctly.

The keyboard layout setting for the port does not match the 
keyboard you are using. On your switch, change the keyboard 
layout setting for the port to match the layout of the keyboard you 
are using.

No power or no response from the target device 
(KVM switch or server)

Check that all cables are securely attached in their sockets.

Update the firmware. See “Firmware Upgrade Mode” on page 12
