Troubleshooting Your Appliance
70
A
Troubleshooting Appliance Startup Failure
If your appliance halts during startup prior to video imaging or LCD messaging,
especially after installing an operating system or reconfiguring your appliance’s
hardware, check for the following conditions.
◆ Invalid memory configurations could cause the appliance to halt at startup
without any video output. See
Memory on page 55.
◆
For all other startup issues, note the LCD panel messages and any system
messages that appear on-screen. See
LCD Status Messages on page 12 and
System Messages on page 24 for more information.
Troubleshooting External Connections
Ensure that all external cables are securely attached to the external connectors on
your appliance before troubleshooting any external devices. See
Figure 1 on page 6
and Figure 4 on page 10 for the front- and back-panel connectors on your
appliance.
Troubleshooting the Video Subsystem
To troubleshoot the video subsystem:
1. Check the appliance and power connections to the monitor.
2.
Check the video interface cabling from the appliance to the monitor.
3.
If two monitors are attached to the appliance, disconnect one monitor. The
appliance supports only one monitor attached to either the front or back video
connector.
4.
Try using a monitor that is known to be working.
5.
Run the appropriate online diagnostic test.
If the tests run successfully, the problem is not related to video hardware.
If the tests fail, see Getting Technical Support on page 2.
Troubleshooting a USB Device
To troubleshoot a USB device:
1. Use the following steps to troubleshoot a USB keyboard. For other USB devices,
go to step
2 .
a.
Disconnect the keyboard from the appliance briefly and reconnect it.
b. Connect the keyboard to the USB port on the opposite side of the appliance.
If the problem is resolved, restart the appliance, enter the System BIOS, and
check if the nonfunctioning USB ports are enabled.
c.
Replace the keyboard with another working keyboard.
If the problem is resolved, replace the faulty keyboard.
