The KVM is unavailable to the T3000

Publication Date:  2012-07-19 Views:  351 Downloads:  0

Issue Description

After the KVM is installed and then connected to the T3000, the KVM has a blank screen and no operation can be performed on the KVM. After the KVM is restarted, servers can be found. However, if the KVM is switched to another server, the KVM has a blank screen again and no operation can be performed on the KVM.

Alarm Information

None

Handling Process

Connect the KVM to a laptop, and the KVM works normally. Then check the display adapter settings of the T3500:
  1. Log in to the SUSE 10 using an SSH tool.
  2. Run the yast command on the CLI.
Choose hardware, and modify the settings of the display adapter and monitor. Then restart the KVM. After that, the KVM works normally.

Root Cause

The KVM requires that the scan frequency of the display adapter be 70 Hz and the screen resolution be 800 x 600. If the requirements are not met, the KVM has a blank screen.

Suggestions

When the KVM works abnormally, connect the KVM to a laptop and check whether the KVM works normally. Note the display adapter settings of the servers.
