Troubleshooting guide – KVM Switch
1. There is no LED display on KVM membrane switch.
• Make sure the power adapter is plugged into the KVM Switch.
• If the LED is still off, perform soft reset to KVM switch.
• If that does not work, power cycle the KVM switch.
2. I can power on the KVM, but I am not getting any picture.
• Switch to another port and check if this port has the same problem
• If the second port is working, check that the screen resolution is the same for both ports.
• Check that the OSD menu is available on the hot keys Scroll lock + Scroll lock + space
bar.
• Make sure the cables are inserted properly and reboot the system.
3. The screen is on but the keyboard and mouse don’t work.
• Check the server by using a different keyboard and mouse.
• For PS/2 servers, the keyboard and mouse are not hot pluggable.
• For USB servers, unplug and plug allowing a few seconds for the bus emulation process
to complete.
• Do not press any keys on the keyboard while the server is booting up. This can cause a
keyboard error or cause the keyboard not to detect the KVM switch.
• Try a different keyboard, but use only 101/102/104-key keyboard.
• Avoid moving the mouse while switching the KVM ports.
4. There is no LED display on the dongle.
• The LED on the dongle will flash when plugged into the USB or PS/2 server.
• The light will then become steady when the KVM switch has connected.
• If the LED light is on and not flashing when plugged into the server, please unplug the
USB or PS/2 and try again.
• Or try another good dongle to verify if problem still appears. If the problem persists,
please contact your supplier.
