Troubleshooting monitor problems when connected to a KVM switch for the 1x8 and 2x8 console manager

Use this procedure to diagnose monitor problems when the monitor is connected to a KVM switch on a 1x8 or 2x8 Console Manager.

Before beginning this isolation procedure, invoke the OSCAR interface on your monitor, as described in "Starting the OSCAR interface". Information on using OSCAR can be found in your Console switch installation and user's guide (680 KB) or Local 2x8 Console manager user's guide (6000 KB). The OSCAR interface uses step by step menus that appear on your monitor allowing you to view, configure and select target devices connected to the KVM switch.

1. Can you start OSCAR?
   • No: Go to Troubleshooting user port problems for the (KVM) switch on a 1x8 or 2x8 console manager.
   • Yes: Go to step 2.
2. Are there any servers that, when selected from OSCAR, display on the monitor?
   • No: Go to step 4.
   • Yes: Go to step 3.
3. On servers that do not display, is the conversion option (CO) cable connected correctly to the graphics adapter?
   • No: Reseat the cable and check the monitor.
   • Yes: Go to step 5.
4. Is your monitor cable seated correctly at the KVM switch?
   • No: Reseat the cable and check the monitor.
   • Yes: Go to step 6.
5. Is your monitor refresh rate set at or below 1280 x 1024 resolution?
   • No: Set the refresh rate at or below 1280 x 1024.
   • Yes: Go to step 8.
6. Perform the following steps:
   1. Connect a different monitor to the same user port on the KVM switch.
   2. Ensure both switch and monitor are plugged in and powered on (green LED indicates power on) and that the correct monitor input is selected.

   Is the monitor still blank?

   • No: Follow the problem determination guide for the monitor you replaced.
   • Yes: Go to step 7.
7. Power cycle your KVM switch by toggling the On/Off switch back and forth, ending with the On/Off switch in the "On" position.

8. Is your server powered on?
   • No: Power on the server.
   • Yes: Go to step 9.
9. Replace the KVM conversion option (KCO) or the USB conversion option (UCO). This will be dependent on the option that is in use and connects to your server.
