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.
- Can you start OSCAR?
- Are there any servers that, when selected from
OSCAR, display on the monitor?
- No: Go to step 4.
- Yes: Go to step 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.
- Is your monitor cable seated correctly at the
KVM switch?
- No: Reseat the cable and check the monitor.
- Yes: Go to step 6.
- 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.
- Perform the following steps:
- Connect a different monitor to the same user port on the KVM switch.
- 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.
- Power cycle your KVM switch by toggling the
On/Off switch back and forth, ending with the On/Off switch in the "On" position.
Is your monitor still blank?
- No: This ends the procedure.
- Yes: Replace the KVM switch.
- Is your server powered on?
- No: Power on the server.
- Yes: Go to step 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.
Is the monitor still
blank?
- No: This ends the procedure.
- Yes: Go to step 10.
- Change the port on your KVM switch to which
the CAT5 cable going to the KCO or to the UCO is attached.
Is
the monitor still blank?
- No: This ends the procedure.
- Yes: Replace the KVM switch.
