Single port KVM over IP switch

7. Troubleshooting

Q 001: The remote mouse doesn’t work or is not synchronous

A 001: Make sure the mouse settings in IP-KVM switch match the mouse model. There are some circumstances where the mouse synchronization process could behave incorrectly, refer to Section 5.3.3 for further explanation.

Q 002: The video quality is bad or the picture is grainy

A 002: Try to correct the brightness and contrast settings (see Section 5.3.4) until they are out of a range where the picture looks grainy. Use the auto adjustment feature to correct a flickering video.

Q 003: Login on IP-KVM switch fails.

A 003: Was the correct combination of user and password given? On delivery, the user ”super” has the password ”pass”. Moreover your browser must be configured to accept cookies.

Q 004: The Remote Console window can’t connect to IP-KVM switch.

A 004: Possibly a firewall prevents access to the Remote Console. Make sure the TCP port numbers 443 or 80 are open for incoming TCP connection establishments.

Q 005: No connection can be established to IP-KVM switch.

A 005: Check whether the network connection is working in general (ping the IP address of IP-KVM switch). If not, check network hardware. Is IP-KVM switch powered on? Check whether the IP address of IP-KVM switch and all other IP related settings are correct! Also verify that all the IP infrastructure of your LAN, like routers etc., is correctly configured. Without a ping functioning, IP-KVM switch can’t work either.

Q 006: Special key combinations, e.g. ALT+F2, ALT+F3 are intercepted by the console system and not transmitted to the host.

A 006: You have to define a so-called ’Button Key’. This can be done in the Remote Console settings.

Q 007: In the browser the IP-KVM switch pages are inconsistent or chaotic.

A 007: Make sure your browser cache settings are feasible. Especially make sure the cache settings are not set to something like ”never check for newer pages”. Otherwise IP-KVM switch pages may be loaded from your browser cache and not from the card.

Q 008: Windows XP doesn’t awake from standby mode

A 008: This is possibly a Windows XP problem. Try not to move the mouse while XP goes in standby mode.

Q 009: Using MacOS X a HTTPS connection fails

A 009: You have to install the IP-KVM switch certificate using our certificate installer, available on the utility CD. Please refer to the instructions on this CD for further information how to install the certificate.

Q 010: Can’t upload the signed certificate in MacOS X

A 010: If an ’internal error’ occurs while uploading the signed certificate either change the extension of the file to .txt or add a file helper using the Internet Explorer preferences for this type of file. Make sure that the encoding is plain text and the checkbox ’use for outgoing’ is checked. Another possibility is to use a Mozilla based browser.
