KVM Login Faults

The KVM is inaccessible.

1. Use a third-party tool, such as PuTTY, to run the telnet IP address:2198 command to check whether the KVM port is normal. The default port number is 2198. Log in to the iBMC WebUI to view the KVM port number in the service configuration. If the Telnet connection fails, directly connect the PC to the iBMC for troubleshooting.
   NOTE:

   If the server does not support remote login over Telnet, use a third-party tool, such as PuTTY, to run the ssh IP address command to check whether the KVM port is normal. If the SSH connection fails, directly connect the PC to the iBMC for troubleshooting.

2. Clear all browser and Java cache and close all browsers. Then re-log in to the iBMC.
3. Adjust the Java security level to medium or lower, or add the KVM address to the Java exception sites.
4. Check the OS, Java and browser versions on the client. Firefox 23.0 is recommended. For details about the operating environment requirements, see the iBMC help document.

1. Follow the handling procedure to replace any faulty modules.
2. Restart iBMC and replace the local PC.
3. Connect the management network port to the local PC directly instead of through a switching network.

The KVM displays an error message.

• If the number of login users exceeds the maximum value, use the iBMC WebUI or CLI to check whether other users are using the KVM. If other users are using the KVM, restart iBMC to force the users to log out.
• If the KVM displays a message indicating an unauthorized user, clear all browsers and the Java cache, and close all the browsers. Then re-log in to the iBMC.
• If the input signal is out of range, check whether the OS resolution exceeds the maximum value 1280 x 1024.

Login to the KVM is successful, but the KVM functions abnormally.

• If the keyboard and mouse cannot be used but services are operating properly, reset the USB and check whether the problem is solved.
  • If yes, no further action is required.
  • If no, restart the service system, run the ipmcset -d clearcmos command to clear the CMOS, and upgrade iBMC and the BIOS.
• If an ISO file fails to be mounted to the virtual DVD-ROM drive, log in to the virtual DVD-ROM drive port over Telnet to check whether the port is normal. Use Smart Provisioning to mount the ISO file to check whether the image source is correct. Then upgrade the iBMC and BIOS.
  NOTE:

  If the server does not support remote login over Telnet, use SSH to remotely log in to the server and check whether the virtual DVD-ROM drive port is normal. Use Smart Provisioning to mount the ISO file to check whether the image source is correct. Then upgrade the iBMC and BIOS.
